IW Tremont A83-2500 Binderless Grade A-83 glass fiber filter media, 0.5micron retention, 2.5cm 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.

Great socks. They stay on your heel! Love the material; breathable and not thick. Love the neutral tone colors.

Perfect thickness and soft feel.
Size: 6-10, Color: Halo Gray/Assorted
Why did you pick this product vs others?: Love theses socks.  It's hard to find socks which won't get pulled down by athletic shoes.  These stay put.

Comfy, great quality
Size: 6-10, Color: White
I’ve had these for quite a while now. They are holding up very well as i wear them a lot for work (coaching). They are very cushiony and most importantly, they do not slip! I would compare these to Bombas but at a significantly better price point.

My favorite socks now!
Size: Medium, Color: Deep Sea/Breaker Blue/Electro Pink
I love socks! And these are quickly becoming my favorites! They do not slide down into your shoe no matter if you are working out or just wearing them for normal everyday use. The price is a little higher than I would normally pay for 3 pair of socks, but after wearing these for a few weeks, I think the quality and comfortability of these socks is well worth the money.
