Quantitative Analytical Filter Paper
We provide a variety of filter papers with different pore sizes and diameters. If you require a specific pore size or diameter that is not available or is currently out of stock, please contact us via email at info@labware.com.hk for further assistance with your order.
LabPro's grades: QT40 | QT41 | QT42 | QT43 | QT44
The quantitative or ashless filter papers are made with 100% high quality cotton linter fibres, which go through a severe chemical process. They have been washed out with a specific acid treatment and finally cleaned from impurities with demineralized water. This process allows reaching an ash content below 0.01%. These papers are used to count during demanding analysis.
