The LR 1000 basic is a cost efficient, modular laboratory reactor designed for optimizing chemical reaction processes as well as for mixing, dispersing and homogenization applications at the laboratory scale. The reactor is especially designed for the unique applications requirements that define the cosmetic and pharmaceutical industries. The temperature of the medium can be as high as 120 ºC. The temperature of the heating source, which is located at the bottom of the vessel, is controlled accordingly to reach the set temperature inside the medium. A PT 100.5 temperature sensor and the corresponding receptacle LR 1000.61 for the lid are included with this package.

  • Digital display for monitoring the speed and temperature
  • Expandable for use with the ULTRA- TURRAX® T 25 digital (Accessory)
  • Standard joint fittings on the lid: 1x NS 29, 3x NS 14 for flexible adaptation of further equipment
  • Vacuum valve included with delivery
  • Anchor stirrer with PTFE-scrapers available (Accessory)
  • Connections to attach a cooling source to the back of the unit
  • Manual adjustable safety circuit
  • Integrated safety shutdown when vessel or lid is removed from the base
