I.W. Tremont A3700 Grade A cut 3.7cm diameter - 100/pk Binderless glass microfiber filter media

The A3700 filter is made from 100% binderless borosilicate glass microfiber, meaning it contains no added binders or chemicals. This results in low extractables and high purity, which is critical for sensitive analytical and laboratory applications.

This Grade A filter provides approximately 1.6 µm particle retention with a fast flow rate, making it ideal for efficiently capturing fine particles while maintaining high throughput during filtration.

The filter is widely used in protein precipitation, cell harvesting, air particulate analysis, and gravimetric testing. It is especially suitable for laboratory workflows requiring consistent and reproducible filtration results.

This product features a 37 mm (3.7 cm) diameter, 0.30 mm thickness, and is supplied in packs of 100 filters. It also has equivalents to other industry standards (e.g., Whatman 1820-037), making it easy to integrate into existing lab setups.

Binderless glass microfiber filters like the A3700 offer higher loading capacity, faster flow rates, and minimal contamination risk compared to cellulose or binder-containing filters. They are especially effective as prefilters or for capturing fine particulate in demanding analytical environments.
