Laboratory scale gas scrubber for use in many air and exhaust cleanup tasks.
Complete scrubber consists of:

• Lower reservoir
• Absorption column with glass-filled PTFE packing support disc
• Glass raschig rings column packing
• High-quality material, exhaust gas outlet column
• Top shower head adapter and PTFE diaphragm
• Liquid transfer pump, 3 ea quick release column clamps
• 3 ea envelope style gaskets
• Fluid cooling condenser, gas inlet adapter PTFE tubing and 5ea PFA compression fittings

The scrubbing fluid is pumped from the round bottom flask upwards into the shower head adapter and then flows counter-current to the exhaust gas through the packed column thereby causing intensive contact between the two. Scrubber can be used by creating either a positive flow through the reaction vessel using a carrier such as nitrogen, or by connection of a vacuum source to the column adapter.

Note: The 20 liter scrubber can handle 25 liters per minute with the CG-1171-50 supplied pump.
