POLYTRON PT 3100D Stand Disperser - Stand-disperser (High-End Line), flexible-use disperser with PC software, RS-232 / USB connection cable. Applications with the highest demands for reproducibility and scaling up can be efficiently performed with this device. The fully digitized control and regulation system is very easy to operate. The illuminated LCD display shows all the parameters, which can be changed with the membrane keypad. 0.1-10,00 mL

POLYTRON PT 6100D Stand Disperser - Stand-disperser (High-End Line), powerful, flexibile-use disperser with PC software, RS-232 / USB connection cable. This instrument meets the highest standards of reproducibility and scaling up and the reserve ­capacities of this motor enable the handling of larger quantities without any decline in quality. The fully ­digitized control and regulation system is very easy to operate. The illuminated LCD displays all required parameters which can be adjusted if necessary, with the membrane keypad. 0.1-30,000 mL


  • Easy operation with an on–off switch and membrane keypad
  • Digital speed control for long equipment life
  • Protection against overheating, overload and blocking
  • Speed stability even with changes in viscosity
  • Easy to adjust motor height (depending on the stand)
  • Aggregates quickly switched with Click & Go coupling
  • Easy aggregate clean–up with EasyClean Design
  • Smallest sizes of particles / droplets: because precise ­analysis require homogeneous samples
  • Efficient sample preparation: because fast dispersion saves time
  • Standard or custom-made aggregates: perfected for and in cooperation with the users
  • Cleaning and disassembly: EasyClean Design makes it very simple
  • Quick coupling of the aggregates: by using Click & Go
  • Best materials available: because without them, we could not call it Swiss Made
  • Durability is a Swiss virtue

      The PT 3100D Stand Disperser is also available as a bundle package that includes: Polytron PT 3100D (100-120V), Stand, Drive Holder, Vessel Holder & Safety Positioning Ring.

      Dispersing aggregates (AKA probes) sold separately.
