T 25 digital ULTRA-TURRAX® Disperser
by IKA

High-performance digital disperser for coarse and fine preparations
The T 25 digital ULTRA-TURRAX Disperser performs high circumferential speeds even when used with small (8 mm) rotor diameters. Designed to emulsify, homogenize and suspend a range of miscible materials, this high-quality lab homogenizer features a unique rotor-stator with a very powerful shear force that quickly macerates tissues and other materials into a homogenous substance. 
  • Volume range: 1 to 2000 ml
  • Speed range: 3000 - 25000 rpm
  • Rotating knob for speed adjustment
  • Accepts stainless steel, saw tooth and plastic disposable dispersing elements (sold separately)
  • Digital speed display ensures accurate protocol adherence
  • Electronic overload protection and electronic speed control
  • Digital error code display for easy troubleshooting
  • Enables high circumferential speeds
  • Emulsifies, homogenizes, or suspends virtually any sample
  • Scalable unit allows usage of identical processes from formulation to production
  • Includes: T 25 digital ULTRA-TURRAX, extension arm, hexagon socket screw, flat key, shaft key, screwdriver DIN 911 and operating instructions

Rotor-Stator Principle
The rotor-stator principle of the IKA T 25 Digital creates an extremely powerful shear force that effectively homogenizes, emulsifies and suspends miscible materials. The close proximity of the outer stationary tube (stator) and the inner turning shaft (rotor) creates a powerful circumferential force that expels tissues and other material between the slots of the rotor-stator. Tissues and other material are macerated and turned into a homogenous substance in a very short amount of time.
