83 mm - 220 mm / 30 min

Grade 222 has a smooth and uniform texture which assures continuous contract of buffer from the chamber through the gel and transfer membrane to the opposite pole or weight

This grade has medium flow rate and good particle retention and is most commonly used for applications requiring high chemical resistance to strong acid and alkali

Grade 74 covers a wide range of general ashless filtration applications
