Vessels with side port and fritted discs


Cylindrical vessel has a GL 18 threaded side port and sealed top and bottom, coarse porosity, fritted discs located to minimize dead space. Top and bottom PTFE plug-style valves reduce the potential for breakage associated with glass stopcocks. 2mm PTFE valves require 1/4-turn to open or close. Valve stems have a 1/4-28 i.d. thread while the o.d. is sized for a 3/8in. compression fitting. Complete with two 2mm PTFE valves and side port cap. (Corning 46800)

Vessels with cap and fritted disc


Cylindrical vessel has a 32mm cap with PTFE-faced liner. Vessel comes with a sealed coarse porosity fritted disc located to minimize dead space. 2mm PTFE bottom valve reduces the potential for breakage associated with glass stopcocks. 2mm PTFE valve requires 1/4-turn to open or close. Valve stem has a 1/4-28 i.d. thread while the o.d. is sized for a 3/8 in. compression fitting. Complete with cap, liner, and 2mm bottom valve. (Corning 46802)

Vessels with side port and removable fritted disc


Cylindrical style vessel has a 2mm PTFE valve at the top, with a GL 18 threaded side port. The 32mm threaded bottom valve assembly incorporates System 45 technology. The coarse fritted disc is easily removed from the PTFE adapter for cleaning and/or replacement. PTFE top and bottom valves require 1/4-turn to open or close. Valve stems have a 1/4-28 internal thread in the stem which allows a variety of adapters to be used. For male 1/4-28 and male Luer adapters, see Cat. No. Z41,741-6 and Z41,742-4 below.
