IW Tremont A83-4250 Binderless Grade A-83 glass fiber filter media, 0.5micron retention, 4.25cm diameterGRADE A 83 Imagine the loading capacity of a binderless glass microfiber filter with the tightly regulated pore size of a microfiltration membrane. Now it's possible with Grade A83. This new grade has a particle retention of 0. 5m. It has >20x loading capacity of an equivalent porosity MCE or CN membrane and >15x the flow rate. Back pressure is nearly non existent in comparison to surface membranes. Chemically inert, pure binderless borosilicate glass

GRADE A-83 - Imagine the loading capacity of a binderless glass microfiber filter with the tightly regulated pore size of a microfiltration membrane.

Now it's possible with Grade A83. This new grade has a particle retention of 0.5µm. It has >20x loading capacity of an equivalent porosity MCE or CN membrane and >15x the flow rate. Back pressure is nearly non-existent in comparison to surface membranes.

Chemically inert, pure binderless borosilicate glass with no sizing additives or other surfactants. Low background noise in LC/GC/MS and very low extractables in presence of aggressive solvents. There are many filter materials which make the claim of "nano-scale" fiber, but Grade A83 is tested by an independent laboratory using the latest in fiber analysis and SEM image quantification. With >85% of the fiber content between 300nm -100nm, this material is truly one of the highest surface area binderless glass microfiber products on the market today.

Very pretty
Style: Length 11 Inches
Seemingly good quality. Just wish it came in half sizes for example 10.5” would be the perfect size for me. 11” was too big, 10” a bit snug. I had to return both.

ABSOLUTELY LOVELY!!!!!!!
Color: B3: Gold Bar + Birthstone, Color: B3: Gold Bar + Birthstone
My fiancé and I lost our 3 month old baby boy. I thought long and hard and hunted through Amazon hoping to find something thoughtful to get him to comfort him and I saw these urn necklaces. I was a bit hesitant because they’re supposed to hold baby’s ashes and I wasn’t sure how he would feel about that but they arrived and we absolutely love them. There are two different chains so he will wear the thicker one and I’ll wear the thinner. The words are written perfectly, the stones are beautiful. It’s small enough that we never have to take them off and big enough to read the words clearly. It’s just the most beautiful and thoughtful gift I could ever give him. This product gets 10 stars!!!!!! Thank you to the company for giving us a gift that will keep our baby boy forever close to our hearts.
