This is a pack of 100 circular Grade 1 qualitative filter papers, each 15 cm in diameter, packed in a cardboard box. Grade 1 is a widely used qualitative paper for routine laboratory work and has medium porosity and a medium flow rate.
Use these circles for routine gravity or vacuum filtrations when students are collecting a precipitate or clarifying a solution. Medium porosity and flow rate make Grade 1 a practical everyday choice, not a fine quantitative paper.
These circles are 15 cm in diameter. Pick a size that sits well in the funnel you already use so the paper can be folded or seated without hanging far over the rim.

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.
