Vacuum Filtration Adapters, Chemglass
Adapters Adapters, Joints with Tube Connectors
Adapters are available in two bottom configuations and four top configurations.

  • Available bottoms include ground joint and threaded
  • Available tops include flare, threaded, and luer joint
  • Some models feature PTFE stopcock

Adapters with [ST] ground joint bottom connect to vials and flasks with [ST] outer joints

Adapters with outer luer joint top connect solid phase extraction (SPE) cartridges, tubes or syringes to a [ST] inner joint, allowing for easy sample concentration and simple clean-up, while reducing possibility of cross-contamination. Adapters 89049-144 and -146 have a 2mm PTFE stopcock between the outer and inner joints to control vacuum source. Adapters with heavy duty tooled flare top are for reduced pressure filtration with plain stem buchner funnels, and accept pluro stopppers (not included). Adapter 89049-156 has a 20-400 GPI threaded top for transfer from vial to vial.

Adapters with threaded bottoms have a 20-400 GPI thread for connection to vials (using a threaded connector) and a sealed-in drip tube to prevent breakage.
