20 L Jacketed Glass Reactor

The HNZXIB S-20L is a 20 L double-layer glass reactor designed for laboratory synthesis, biopharmaceutical work and new-material preparation. It operates on a 220 V 50/60 Hz supply and uses GG17 high-borosilicate glass for chemical resistance and high transparency. A 120 W stirring motor drives a PTFE agitator at speeds up to 600 rpm with a maximum of 1300 rpm. The unit is mounted on a SUS304 stainless steel frame.

Upgrade from single-layer vessels

This reactor replaces single-wall glassware when precise temperature control across a wide range is required. The jacketed interlayer accepts circulating heat-transfer fluids such as hot oil, water or freezing liquid to maintain constant heating or cooling during reactions. Vacuum capability in the inner layer enables reduced-pressure processes that open vessels cannot support. The jump is worth it when protocols demand both thermal stability and vacuum operation in a single 20 L vessel.

Installation and common issues

The reactor arrives on a stainless steel frame with an electric stir motor, PTFE agitator, universal joint and bottom drain valve already fitted. A reserved glass thermometer casing allows direct temperature monitoring of the solution. The large bottle mouth simplifies cleaning between batches. Users must supply compatible circulation equipment for the jacket and verify that the 220 V supply matches local mains. Improper fluid connections or excessive stirring torque can damage the glass joints.

Questions about this item

What frame size and material are needed to support the 20L glass vessel?

The reactor mounts on a SUS304 stainless steel frame designed for the 20L capacity.

How is the PTFE agitator connected to the 120 W motor, and what step is often missed?

The agitator attaches via a 12 mm stirring shaft and universal joint; the joint must be secured before starting the motor.

Which parts of the jacketed reactor need periodic replacement?

The GG17 high-borosilicate glass vessel, PTFE agitator, bottom drain valve and thermometer casing are the primary wear items.
