Glass Filter Holders & Assemblies
Filter Glass Assembly, Glass Filter Assembly - For Vacuum Filtration

Sterlitech glass filter holders are reusable, easy to clean, and composed of chemically resistant borosilicate glass. Filter holders include funnel, clamp, base, and stopper. Assemblies include filter holder, receiving flask, and adapter. 

We offer a variety of membrane support materials and funnel sizes for glass holders and assemblies:

  • Sintered glass support is recommended for low pH solutions and exhibits lower flow rates than other materials (KG models)
  • Stainless steel support maximizes flow rate with viscous solution and doesn’t shed particles (KGS)
  • PTFE support has high chemical compatibility and higher flow rates, can be used interchangeably with the stainless steel option (KGT)
If you're looking for replacement parts, please see below for all available accessories.
