Low nonspecific binding membrane with excellent chemical resistance. Use with biological or protein-based samples or HPLC sample prearation. Low extractables and good flow rate characteristics. The 4mm filters can be used for volumes up to 2mL, the 13mm filters have an excellent flow rate for use with volumes up to 10mL, the 25mm filters can be used for volumes up to 100mL, and the 30mm filters for larger volumes. The 0.2µm pore size filters can be used for “cold” sterilization.
The polypropylene/glass prefilter filter (66064-410) incorporate a 1.0µm borosilicate glass prefilter that permits greater throughput and extends membrane life when used with high particulate content samples. These filters are recommended for sample preparation in HPLC.
