Chromatography sample vials and inserts with one-piece design provides a safe, secure sample containment for use with robotic arm autosamplers

Vineland, NJ (PRWEB) February 02, 2012

Here is a unique product for researchers tasked with managing a lot of chromatography sample vials in their laboratories: the new 300µL Interlocked R.A.M. (Robotic Arm Machine) Vial with 9mm Thread Finish, by J.G. Finneran Associates. Composed of a clear or amber Type I borosilicate glass, the vial and insert are fused together keeping the insert permanently in place. This design enables accurate automated injection, and eliminates contamination risk around the seam or space between the neck of the vial and the insert. The Interlocked R.A.M. Vial arrives ready to use saving valuable time in the laboratory.

The Interlocked R.A.M. Vial is specifically designed to work in robotic arm autosamplers such as those available from Agilent Technologies and others. The 12mm x 32mm outer dimensions is designed for robotic arms to easily grasp. Chromatography samples are contained in a clear Type I borosilicate glass 300µL conical tip insert. The Interlocked R.A.M. Vial includes a marking spot, which can be written on with a pencil. The vial is also available with a 9mm Screw Thread Closure option.

Learning to work Lean in L-A

Yu — Sun, 29 Jan 2012 06:58:00 +0000

For decades, Thos. Moser Cabinetmakers handcrafted heirloom furniture the same way, at pretty much the same speed.

Peter Brown, operations manager for Strainrite in Auburn, a manufacturer of bag filters, holds a sample of its product in the production plant.

It did it to maintain quality, yes, but the Auburn company also didn’t know how else to work. It made its chairs, tables and beds in small batches and stockpiled the inventory. When customers started asking for variation — different styles, different sizes, different colors — Thos. Moser had to be more flexible. And the company couldn’t do it.

Orders were taking up to six months to fill.

“The same principles didn’t work for us,” said Manufacturing Manager Rick Foss.

So Thos. Moser called in the Maine Manufacturing Extension Partnership, or MEP, a little-known government-backed organization that helps small and medium Maine manufacturers become more efficient, productive and competitive. Through its Lean initiative, Maine MEP cross-trained Thos. Moser workers, changed the manufacturing floor’s layout to make it more efficient and created work centers for specific products so components and products could be made in the same area at the same time and with less opportunity for error.

The company, which used to make 25 to 30 types and styles of furniture, now makes more than 250. It handcrafts products in four months — a third less time than before. Soon, it believes, it can get those pieces done in two months, without sacrificing quality.

Foss credits Maine MEP for the turnaround.

“It’s great. We’ve changed our business practices for the better two-fold, three-fold,” he said.

Thos. Moser isn’t the only one, even in the small city of Auburn. The Strainrite Companies, a liquid filtration manufacturer, used Maine MEP to help improve both efficiency and employees’ job satisfaction. Falcon Performance Footwear used Maine MEP and recently cut its production time in half.

Over the past 13 years, Maine MEP has helped dozens of manufacturers across the state streamline, cut costs and become more efficient, all without cutting one of the most expensive parts of business — employees.

“It’s about eliminating waste. It’s not about eliminating jobs,” said MEP Project Manager Wayne Messer.

That’s something manufacturers like. During the economic downturn, demand for the Maine MEP’s Lean initiative has remained steady, even when businesses have to pay for it. In the long run, they say, the savings of time, money and energy is worth it.

“It’s great financially for us and it’s great for the customers as well,” said Falcon President Carl Spang.

The faster the better

When a business asks Maine MEP for help, project managers — people with industry experience — visit the company to assess its situation. Sometimes they can pick out what’s wrong just by walking the manufacturing floor.

“You can actually see areas where an organization is very inefficient,” Messer said. “You can see piles of inventory that shouldn’t be there because every time you’ve got inventory piled up you have labor and materials, which are dollars, tied up on the floor that aren’t being put to good use.”

Visits and assessments are free, as are the suggestions specialists makes. If the company wants to hire Maine MEP to help make those changes, that can cost anywhere from hundreds of dollars to tens of thousands of dollars, depending on service and time required. Projects can take days to weeks to complete.

Thos. Moser has sought Maine MEP’s help several times.

In 1998, the furniture maker participated in “Lean 101,” a course that simulates a poorly run business and shows company leaders and employees how to fix it. In 2003, Maine MEP helped Thos. Moser streamline production by creating work centers for specific products. Until that point, employees made components — table legs and table tops, for example — and assembled them at different times and in completely different areas.

“You never knew if your parts were right, if they fit,” Foss said. “Now where we build them in the product family work centers, they build the parts and they assemble at the same time.”

In 2005, Thos. Moser asked Maine MEP to help train its workers in Lean techniques to make their work more efficient. The company also changed the layout of the production floor and cross-trained employees.

Today Thos. Moser is working with Maine MEP to review the administrative side of the business, including order entry, shipping and supply. It hopes to cut its order-to-door time to a fraction of what it once was.

“We can satisfy (customers) quicker, we can put the money back into the company quicker, and we can generate more customer interest, because when they hear 17 weeks or 20 weeks, it’s a long time and it discourages some customers,” Foss said.

Falcon Performance Footwear asked the Maine MEP for help late in the summer of 2010, and it has worked with the group constantly since. The most significant change: making shoe parts — such as leather uppers and bootie inserts — at the same time, rather than one right after the other. The change, from sequence manufacturing to parallel, meant there wasn’t as much waiting around. The company cut its boot production time in half, from 14 days to 7.

“All of our fire boots are made to order. We have no finished goods inventory, so the faster we can make them the better off we are,” Spang said.

He has come to rely on Maine MEP to provide “a second set of eyes.”

“You begin to accept things the way they are. You don’t question as much as you should when you’re associated with an operation over time and you might be a little risk averse,” Spang said. “MEP is very good at taking a fresh look at things, understanding the possibilities and pursuing them in a rational way.”

At the Strainrite Companies, Operations Manager Peter Brown has been working with Maine MEP for years. He first encountered a Manufacturing Extension Partnership in New Hampshire several years ago — funded in part by the U.S. Department of Commerce, there’s at least one MEP in every state — and he thought the group’s Lean focus could help his new employer in Auburn. Like Thos. Moser and Falcon Performance Footwear, Strainrite learned ways to make manufacturing more efficient. But, Brown said, his company’s biggest change was employee satisfaction.

As part of the Lean initiative, workers are encouraged to bring up issues bothering them, whether the problem is low morale or a high scrap rate on the manufacturing floor. Those issues are then addressed.

“We saw (improvement) in terms of employee morale, employee longevity, employee satisfaction. Which, in and of itself, translates into improvements in efficiency, better relationships between management and employees, and overall better work environment,” Brown said.

Over the past 10 years, Maine MEP has helped 600 to 800 of Maine’s nearly 1,800 small- and medium-sized manufacturers, assisting with technology, supply chain management and international sales. Although businesses can ask for help with efficiency only, nearly all of MEP’s services involve Lean initiatives in some way.

A nonprofit organization, Maine MEP’s funding comes in equal parts from the federal government, the state and the fees manufacturers pay for service. The group’s annual federal funding is based in part on its effectiveness. It loses that funding if surveys show manufacturers aren’t getting enough out of the program.

So far, that hasn’t been a problem. In Auburn, Thos. Moser, Falcon Performance Footwear and Strainrite Companies all said they would recommend Maine MEP and its Lean work.

“Absolutely,” said Brown at Strainrite. “I’ve been a Lean cheerleader for a long time.”

At Maine MEP, Messer believes Lean — and getting leaner — will only become more important to companies’ survival.

“It’s not a destination, it’s a journey,” he said.

Rising carbon dioxide confuses brain signaling in fish

anthea — Fri, 20 Jan 2012 08:39:19 +0000

A new study may explain how rising carbon dioxide concentrations — and the ocean acidification they induce — can cause topsy-turvy changes in the behavior of fish. Like a flipped switch, the normal response of nerve cells can reverse as acidifying seawater perturbs how a fish regulates acids and bases in its body, including the brain.

“This could be a big deal,” says neurobiologist Andrew Dittman of the National Oceanic and Atmospheric Administration’s Northwest undersink water filters Fisheries Science Center in Seattle. Dittman, who was not affiliated with the study, says the new findings could go a long way toward explaining curious sensory changes observed in fish exposed to acidifying waters. The scary scent of predators, for example, can suddenly become alluring.

The idea emerged after Philip Munday of James Cook University in Townsville, Australia, told Nilsson of behavioral quirks his laboratory fish were exhibiting in a high–carbon dioxide 96 well plates environment — conditions exemplifying ocean waters a half-century or more from now. Nilsson, a neurophysiologist, speculated that a connection between nerves and chemistry might be involved. “It was very much an ‘Aha’ moment,” Munday says.

Retreating Glaciers Threaten Water Supplies

anthea — Fri, 13 Jan 2012 01:59:39 +0000

Glaciers are retreating at an unexpectedly fast rate according to research done in Peru’s Cordillera Blanca by McGill doctoral student Michel Baraer. They are currently shrinking undersink water filters by about one per cent a year, and that percentage is increasing steadily, according to his calculations.

But despite this accelerated glacial shrinking, for the first time, the volume of water draining from the glacier into the Rio Santa in Northern Peru has started to decrease significantly. Baraer, and collaborators Prof. Bryan Mark, at the Ohio State University, and Prof. Jeffrey McKenzie, at McGill, calculate that water levels during the dry season could decrease by as much as 30 percent 96 well plates lower than they are currently. “When a glacier starts to retreat, at some point you reach a plateau and from this point onwards, you have a decrease in the discharge of meltwater from the glacier,” explained Baraer.

“Where scientists once believed that they had 10 to 20 years to adapt to reduced runoff, that time is now up,” said Baraer. “For almost all the watersheds we have studied, we have good evidence that we have passed peak water.” This means that the millions of people in the region who depend on the water for electricity, agriculture and drinking water could soon face serious problems because of reduced water supplies.

Fast and efficient filtration of cell culture media

Yu — Sun, 08 Jan 2012 12:57:09 +0000

Specialists in quality laboratory plasticware - Membrane Solutions has announced a new range of disposable syringe filters that provide fast and efficient filtration of cell culture media.

Manufactured in a Class 100000/ISO Class V clean room to ISO 9001:2008 and EN ISO 13485:2003 manufacturing standards ensures all Porvair syringe filters are free from DNA/RNA, DNAse/RNAse and Pyrogen contamination.

Stringent quality testing means each syringe filter performs reliably to specification.

With three membranes to choose from an optimised syringe filter is available for most applications.

Polyethersulfone membrane syringe filters exhibit a low affinity for proteins and extractables making them ideal for pre-filtration and filtration of buffers and culture media.

The mixed Cellulose Ester membrane efficiently binds trace proteins making them the syringe filters of choice for filtration of aqueous solutions. Porvair’s hydrophobic Nylon membrane offers excellent chemical compatibility across a wide pH range enabling it to be used for the filtration of either aqueous or organic solvents.

New Materials Remove Carbon Dioxide

anthea — Fri, 06 Jan 2012 09:38:35 +0000

Scientists are reporting discovery of an improved way to remove carbon dioxide — the major greenhouse gas that contributes to global warming — from smokestacks imaje inkjet filters and other sources, including the atmosphere. Their report on the process, which achieves some of the highest carbon dioxide removal capacity ever reported for real-world conditions where the air contains moisture.

Alain Goeppert, G. K. Surya Prakash, chemistry Nobel Laureate George A. Olah and colleagues explain that controlling emissions of carbon dioxide (CO₂) is one of the biggest challenges facing humanity in the 21st century. They point out that existing methods for removing carbon dioxide from smokestacks and other sources, including the atmosphere, are energy intensive, don’t work well and have other drawbacks. In an effort to overcome such obstacles, the group turned to solid materials based on polyethylenimine, a readily available and inexpensive polymeric material.

Their tests showed that these inexpensive materials achieved some of the highest carbon dioxide removal rates ever reported for humid air, under conditions that stymie other related materials. After capturing carbon dioxide, the materials give it up easily so that the CO₂ can be used in making other substances, or permanently isolated from the environment. The capture material then can be recycled and reused many times over without losing efficiency. The researchers suggest the materials may be useful inkjet filters on submarines, in smokestacks or out in the open atmosphere, where they could clean up carbon dioxide pollution that comes from small point sources like cars or home heaters, representing about half of the total CO₂ emissions related to human activity.

Mongolia focuses on bag filters to reduce air pollution

Yu — Tue, 03 Jan 2012 12:33:30 +0000

Inner Mongolia is the main location of the Chinese coal industry, iron industry and steel industry and suffers from considerable air pollution. Among other things, this is caused by the biggest arch mine of Inner Mongolia, the biggest niobium mine of China and the worldwide biggest rare earth mine. The region has put in place a new five-year plan to tighten emissions, reducing industrial dust issues and improving of air quality.

The delegation was interested in the bag filtering installations of Intensiv-Filter, which show energy-efficient solutions and a reduction of dust issues. A return visit of Intenisv-Filter management to Mongolia is planned shortly.

Are Superluminal Neutrinos Possible?

anthea — Mon, 02 Jan 2012 07:34:45 +0000

When an international collaboration of physicists came up with a result that punched a hole in Einstein’s theory of special relativity and couldn’t find any mistakes in their work, they asked the world to take a second look at their experiment.

Responding to the call was imaje inkjet filters Ramanath Cowsik, PhD, professor of physics in Arts & Sciences and director of the McDonnell Center for the Space Sciences at Washington University in St. Louis.

Online and in the Dec. 24 issue of Physical Review Letters, Cowsik and his collaborators put their finger on what appears to be an insurmountable problem with the experiment.

The OPERA experiment, a collaboration between the CERN physics laboratory in Geneva, Switzerland, and the Laboratori Nazionali del Gran Sasso (LNGS) in Gran Sasso, Italy, timed particles called neutrinos traveling through Earth from the physics laboratory CERN inkjet filters to a detector in an underground laboratory in Gran Sasso, a distance of some 730 kilometers, or about 450 miles.

OPERA reported online and in Physics Letters B in September that the neutrinos arrived at Gran Sasso some 60 nanoseconds sooner than they would have arrived if they were traveling at the speed of light in a vacuum.
