Rocker – Diaphragm Liquid Pump (Aligator 200)

Alligator 200 has a liquid diaphragm pump built-in, which directs the filtered liquid directly into the waste. This saves time and simplifies the filtration process. It does not require a waste bottle, as is necessary with conventional air pumps. Save workspace by getting rid of hoses and waste bottles. The Alligator 200 complies with ISO 8199 and is ideal for microbiological sample filtration.

Ideal for:

  • Microbiological test by Membrane Filter Technique
  • Suspended solid test for water monitoring
  • General filtration without collecting filtrate
