How the shop filters work
Category, membrane, diameter, pore size, pack size, price, and stock. Two choices in one group mean either. Choices in different groups mean both.

What a clearer bench means here
Clear does not mean a bare bench or a styled one. It means the next person can see which filter, which box, and which tool belongs where.
What hydrophobic and hydrophilic mean on a listing
Two PTFE listings use these words so the groups can be told apart. The words are not a test report, and they do not say the filter suits a named sample.
13 mm, 25 mm, and 33 mm
Diameter is the width of the filter disc. In this shop the numbers that appear are 13 mm, 25 mm, and 33 mm. 25 mm is not 0.25 µm.
When the organizer does not fit the shelf
Lab Organization, pipette accessories, and benchtop tools are on the menu. They do not all have products yet. An organizer that does not fit is still the problem those categories are for.
Pore size, written the way the shop writes it
0.22, 0.45, 0.8, 1.2, and 2.0 µm are the pore sizes in the current catalog. The number is not the diameter, and a finer pore is not a recommendation.
What to write before you order
If the product page does not answer you, send the product name, the quantity and option, and the job. Shipping and returns stay on their own pages.
The membrane names on the packs
Nylon, PES, PTFE, MCE, PVDF, and BT are the membrane names printed on current listings. Here is what those letters stand for, and the claim this page will not add.
Three packs that look the same
Nylon, PTFE, and MCE can look identical in a product photo. So can 0.22 and 0.45. The difference has to live on the label, not in the thumbnail.
How to read a syringe filter title
Diameter, membrane, pore size, and pack size are the four lines a title in this shop is trying to answer. This note is how to compare them, and what it will not claim.
