Membrane Solutions LLC has a long history of enabling efficient sample
preparation within the life science, environmental analysis, clinical,
forensic and industrial quality control markets. We are constantly devising
ways to improve sample prep to meet the demands of lower detection limits
while efficiently processing more samples.
We provide filtration products for essential separation and purification
processes and help scientists anticipate and avoid problems in their
downstream analyses by finding the optimum sample preparation method.
Membrane Filter
Membrane filters or "membranes" are Micro porous films with specific
pore size ratings. Membranes retain particles and microorganisms
that exceed their pore ratings by acting as a physical barrier and
capturing such particles on the surface of the membrane.
Syringe filters
MS
® Syringe Filters are simply quality filters, well packaged, and
offered at a fair and competitive price. The Classic range is available
in all of the major membranes including Nylon, PTFE, PES, MCE and
PVDF which are supplied in 13mm, 25mm and 33mm formats in virgin
polypropylene housings.
Vacuum Filter
Vacuum Filter is used primarily in microbiological and analytical
procedures that involve collecting a particulate (bacteria, precipitate,
etc.) from a liquid suspension. Liquid poured into a funnel passes
through a filter, which retains the particulate, and filtrate can
be collected into a filter flask, directly or via a vacuum manifold.
Applying vacuum reduces process time compared to gravity flow.
Microbiology Test
Mixed Esters of Cellulose (MCE) or Cellulose Acetate(CA) are best
for microbiology and environment monitoring test. Contrasting grid
lines facilitate counting colonies on the filter surface and are
tested to assure freedom from grid line inhibition. Membrane Solutions
offers MCE monitoring membrane discs in diameters in 37mm 47mm 50mm
and other diameter. Also for different bacteria testing, we have
0.10um, 0.22um, 0.45um, 0.65um, 0.80um, 1.00um for choose. Black
and Green membranes are tested for optimal recovery of yeast and
total bacteria. Membrane Solutions MCE membranes are also tested
for freedom from grid line inhibition and optimal color reactions
on appropriate test media.
