Fixed sample volume adjustable from:

  • 12 - 200 ml (WS Porti, WS 312, WS 316 SE)
  • 15 - 350 ml (WS 98, WS 316, WS 316 SR)

On request, larger sample volumes are available. Larger sample volumes can also be created by drawing multiple samples in succession.

The metering vessel is made of borosilicate glass, and is therefore dishwasher-safe as well as acid-, alkali- and temperature-resistant.

Further advantages are:

  • No recalibration of sample volume necessary, even after cleaning
  • Highest repeatability
  • No parts to regularly replace, such as with peristaltic pump hoses
