Jacketed Glass Reactor LJGR-B29

Name: Jacketed Glass Reactor LJGR-B29
Brand: Labtron
SKU: LJGR-B29
Rating: 4.9 (904 reviews)

Labtron Jacketed Glass Reactor LJGR-B29 offers a 2 L G3.3 borosilicate glass vessel with a heat transfer fluid circulated through the jacket to regulate reaction temperature from −50 to 250 °C. The brushless overhead stirrer with PTFE paddle and seals operates from 30 to 2200 rpm, while the constant-pressure dropping funnel, serpentine reflux condenser and bottom discharge valve support controlled feeding, reflux and vacuum distillation. This sealed double layer glass reactor keeps reaction, vapour condensation and distillate collection under one controlled atmosphere.

The G3.3 high borosilicate glass vessel resists strong corrosion, including aqua regia.
The jacketed design circulates heat transfer fluid to control reaction temperature from −50 to 250 °C.
The transparent glass body allows real-time observation of colour changes and bubbles during the reaction.
The multi-port glass lid allows easy fitting of the condenser, dropping funnel and temperature sensor.
PTFE sealing components support vacuum operation down to −0.095 MPa for reduced-pressure distillation.

Jacketed Glass Reactor LJGR-B29 is used in fine chemical, biopharmaceutical and new material research laboratories for pilot-scale synthesis. Jacket temperature control and a sealed reflux and distillation setup allow reactions, solvent recovery and scale-up trials within one system.

Models of Jacketed Glass Reactor

Jacketed Glass Reactor supports controlled mixing with adjustable stirring speed, ensuring consistent reaction dynamics in varied experiments. They maintain thermal stability using a jacketed layer for fluid circulation without exposing the medium. Their borosilicate glass build withstands thermal stress and chemical exposure over time. These systems include a display panel for monitoring key parameters during operation. Our glass reactor is suited for synthesis, distillation, extraction, crystallization, and pharmaceutical development.
