Dispensette® III, Digital Easy Calibration

The wide range of Dispensette® dispensers provides premium dispensing options for the complete spectrum of liquid reagents.
  • SafetyPrime recirculation valve reduces risk of splashes caused by air bubbles during instrument priming and permits recirculation during priming to avoid reagent waste.
  • Safety discharge system reduces the risk of inadvertent dispensing and splashes if discharge tube is improperly installed or missing.
  • To allow the bottle label to face the user, the valve block can be rotated 360°.
  • A telescoping filling tube adjusts easily to different size bottles - without measuring or cutting.
  • The min. force needed to operate the floating piston makes serial dispensing convenient and effortless.
  • Discharge tube safety screw cap protects against reagent contact and is easy to attach and remove, even while wearing gloves.
  • The 45 mm standard thread plus the incl. adapters fit common lab bottles.
  • Easy to dismantle for cleaning and replaceable filling valves.
  • Autoclavable at 121 °C.
  • Conformity certified and easy to calibrate in order to comply with ISO 9001 and GLP guidelines.

Items supplied:
Each Dispensette® is conformity certified and supplied with performance certificate, discharge tubing, telescoping filling tube, SafetyPrime recirculation valve (optional), mounting tool and adapters of PP.

Calibrated to deliver (TD, »Ex«). Error limits acc. to the nominal capacity (= max volume) indicated on the instrument. A = accuracy, CV = coefficient of variation.

Three different approaches to volume adjustment are available:
  • Digital, Easy Calibration:
Digital display: especially easy to read and dispensing volume can be set accurately and reproducibly (mechanical counter). Easy calibration: innovative technique for adjustment in seconds without tools.
  • Analog-adjustable:
Fast volume adjustment with analog slide. Simple calibration adjustment with a supplied tool. Changes from factory setting are indicated.
  • Fixed-volume:
Fixed volume for standard applications. Simple calibration adjustment with a supplied tool.
Areas of application:
Dispensette® III:Red colour code. Ideal for dispensing even of aggressive reagents, incl. concentrated acids e. g. H3PO4, H2SO4, bases like NaOH, KOH, saline solutions and many solvents (e. g. methanol, acetonitrile) - directly from the supply bottle.
Dispensette® Organic:Yellow colour code. Ideal for dispensing of organic solvents, incl. chlorinated and fluorinated hydrocarbons (e. g. trichlorofluoroethane, dichlormethane), concentrated acids (e. g. HCl, HNO3),
trifluoroacietic acid (TFA), tetrahydrofuran (THF) and peroxides.
DE-M marking. Digital-adjustable volume. (Illustration with SafetyPrime recirculation valve).
