Bottletop Dispensers Dispensette® S

The Dispensette® S bottletop dispensers combine innovative ideas with proven technology and makes dispensing safer and convenient.
  • Discharge tube, with or without recirculation valve.
  • Valve system: no additional sealing rings required; this greatly facilitates cleaning and preparations for autoclaving.
  • Simple priming by optimised flow channels.
  • Less dispensing force - especially with large volume instruments.
  • Safe volume setting with internal scalloped track (analog-adjustable instruments).
  • Pivoted screw cap: does not disturb dispensing.
  • Autoclavable at 121 °C.
  • Easy to calibrate and adjust in order to comply with ISO 9001 and GLP guidelines.
  • Easy to dismantle for cleaning.
  • Replacable filling and discharge valve with safety bulb (locks when discharge tube is not assembled).
  • The 360° rotatable valve block allows the bottle label to face the user.
  • Telescoping filling tube adjusts easily to different size bottles.
  • DE-M marking.
