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.

Great pans for meal trains or prep
Size: 10P -9×13 In, Color: Silver
Great pans for delivering meals to people or prepping freezer food. Four stars because they are slightly smaller than a 9x13 pan, but they still work great for most recipes. They are much cheaper than the stores.

Reviews for this product were varied, but I decided to give it a go. A wise choice. These arrived on time, in a plastic bag, in a box, inside a sturdier box…in perfect condition. They are very sturdy compared to most I’ve seen. I used them in preparing a meal for a family who lost a loved one. If they easily accommodate 5 lbs of potato salad, I’d say they’re sturdy. I also used them for sliders, and a couple of fruit trays.
