This listing is a pack of 100 qualitative filter-paper circles, 15 cm in diameter, in a student-quality grade for school and home labs. The pore size is 8–10 microns. Teachers use this size in medium funnels for everyday gravity filtration.
The 15 cm circle fits a mid-size funnel and is a common classroom choice for filtering precipitates and separating solids from liquids when quantitative ash work is not required.
Keep the pack dry and closed when it is not in use.

Jesse C...I contacted Geyer via email. I had an email back within minutes!.. A back and forth via email sometimes takes days with other companies and customer service doesn’t happen like this very often. When it does, it’s much appreciated. Brett at Geyer was very polite and accommodating!
John C.The customer service rep went as far as to reach out to the manufacturer of a product to answer my question, and then provided pictures. She really went above and beyond and answered the question thoroughly and gave me exactly the information I was looking for. This entire process was also extremely fast.
Robert C.I called to ask how to submit a Tax Exempt Certificate for my library and spoke to a real person, no automation or asking me to press a number. He was friendly, helpful and got our Tax Exempt status established immediately.
Mischelle F....I don't think I've ever experienced that level of customer service before, and taking it into consideration along with the quality of their products, I would absolutely recommend Geyer to fellow teachers.
