This pack contains 100 circles of 18.5 cm (7.28") qualitative filter paper. The paper has high retentivity, a medium filtering speed (85 gsm), and a 10-micron pore size for general laboratory filtering and qualitative analysis.
Use the circles for gravity filtration of precipitates and for qualitative analysis. The 18.5 cm diameter fits larger funnels than a 15 cm circle.
Medium speed and a 10-micron pore size are a practical everyday combination for school labs.

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.
