1) Membrane Material - yes, xxx will be able to supply the material if
Membrane Solutions cannot source / match it, but I would prefer to buy the
complete unit from your Firm. Please advise if you cannot identify a
similar material with the same properties as either of the 2 specs. I’ve
provided.
2) I do not have any more specific information as to what material GE /
Whatman has used on these, and I do not want to inquire to them right now -
it would reveal I am looking to replace them as our Supplier. Hopefully you
will be able to analyze the samples I send you and determine the optimum
material.
3) Regarding ”QA Certificate”. I’m not sure what you’re asking. Our Sr.
Chemist has recent test results regarding flow rates from when he qualified
the new membrane material. Is that what you’re looking for?
4) I will send you 10 samples today. As indicated in my RFQ message, our
annual usage is 120,000 units, and I am looking to place a 12-month Blanket
Purchase Order for that amount of Units.
5) Please send me complete information on Membrane Solutions LLC. Does your
Firm actually manufacture these, or just distribute them? Who makes the
syringe filters? How long has Membrane Solutions been in operation? What is
the size of the company? Do you have an actual facility?

Dear Mike:
 
I have feedback from our product director and he confirmed we have exact same design product, which is our “simplepure” 25mm syringe filters. He will send me autocad drawing later after approval from our sales group (for confidential reason), but I have attached some product pictures for you to review:
 

 
On the other hand, after [...]

We are an OEM of Precision Gas Detection
Equipment. We use a hydrophobic filter unit (syringe filter) in our
remote-sensing Probes. 
Our Annual Usage is 120,000 units. We are currently
using a  unit, but are exploring immediate alternatives.
Attached are the drawing for the filter we’re using, as well as 2 different
filter media materials.

Hi John,
 
If you reject to it, I will be in a bad situation. Yesterday, our billing department didn’t allow to sent out the goods first until the shipping fee is solved. But I thought you would understand it, so promise our billing department there is no problem from your side.
