• Minimum sample hold-up: Unit housings are specifically designed to maximize sample recovery • High purity: Non-pigmented housing and integral filter sealing assure that filtrates will not be adulterated due to pigment, dye, or adhesives leaching into the filtrate.

• Convenient: Each unit is clearly marked with an identifying code to denote pore size, membrane material and housing polymer.

• Sterile: Units can be purchased pre-sterilized and individually packaged, or non-sterile in bulk pack.

• All polypropylene can be autoclaved.
