Filters
Filters are essential in research laboratories and many other industries for removing particulates and creating environments conducive to a wide array of experiments and procedures. The devices come in different forms including in-line filters, paper discs, small capsules, and large ventilation panels. Filters also purify and concentrate the liquids and gases required for testing. For air, this means removing pollution, moisture, and solid airborne particulates; for liquids, this means removing impurities and small contaminants.

VWR® Hichrom Precolumn Filters
Supplier: Avantor
Placed immediately before the column, the precolumn filter traps particles introduced with the sample. For samples, which may irreversibly absorb onto the column, the use of guard cartridges is strongly recommended.

VWR® Hichrom Last Drop™ Inlet Filters
Supplier: Avantor
The Last Drop™ eluent filter utilises a flat element, which sits parallel to the bottom of the reservoir, allowing the filter to draw all but the last 2% of the eluent without drawing air into the system. The filter consists of a 316 stainless steel or PTFE filter element in an inert housing.
