PT2500E POLYTRON® PT 2500 E EA 0.05 - 2500 ml 500 - 30000 rpm $1,888.90  

POLYTRON® PT 2500 E Stand Dispersion Unit (Ecoline)

 « Application volumes 0.01 - 250 ml »

The PT2500 E is the ideal solution for cost-conscious laboratories. It is able to perform homogenizations with volumes from 0.05 to 2500 ml. The electronic control system continuously monitors the speed and automatically adjusts it, keeping it constant with changing viscosity. The speed is easily seen on the large digital display.
Aggregates with a variety of styles and diameters are available to provide optimum particle size reduction when using this drive.  There are  many different styles of aggregates available from 3mm in diameter for volumes down to 0.01 mL  to 12mm for volumes up to 250mL.  If cross contamination from sample to sample is a concern, we offer single use synthetic aggregates in 7 and 12 mm diameters.  One of the more recent additions to our line is the PT-DA 20/2 X EC aggregate which was specifically designed for homogenizing tablets.


  • 500 Watt motor provides sufficient power and high speed necessary for efficient particle size reduction
  • Digital motor speed control from 500 to 30,000 rpm
  • Aggregate tip speeds up to 32 m/s produce the finest particles possible
  • Soft start prevents splashing of homogenate from sample vessel
  • Thermal fuse for overload protection
  • Speed remains constant even when viscosity changes
  • Aggregate replacement using one-handed quick-release coupling
  • Insulated motor housing keeps motor noise to a safe, approved level
  • Various models of dispersing aggregates which are Easy-to-Clean and  designed for many different applications


Vessel holders or anti-slip mats with our stands.
Glass dispersion vessels which eliminate vortexing and improve homogenization efficiency.
