20L Jacketed Glass Reactor

The HNZXIB S-20L is a 20-litre double-layer glass vessel designed for laboratory synthesis, biopharmaceutical work and new-material preparation. It operates on a 110V 50/60Hz supply and uses GG17 high-borosilicate glass for chemical resistance and high transparency.

Electric Stir Motor with PTFE Agitator

A 120W gear motor drives a 12mm PTFE stirring shaft through a universal joint at speeds from 0 to 600 rpm, with a maximum of 1300 rpm and 1200 g·cm torque. The stainless-steel SUS304 frame supports the assembly, while a reserved glass thermometer casing and LCD display allow direct temperature monitoring of the reaction solution.

Vacuum and Thermal-Cycling Limits

The inner layer runs under vacuum or negative pressure for stirring reactions, while the jacket circulates heat-transfer fluid — hot oil, water or freezing liquid — for heating or cooling. A bottom drain valve simplifies product removal, and the large bottle mouth eases cleaning, but the unit provides no internal temperature control beyond the external circulating medium.

Questions about this item

How often should the PTFE agitator and universal joint be inspected or replaced on the S-20L?

The PTFE agitator and universal joint should be inspected regularly for wear or chemical degradation; replacement timing depends on the specific solvents and temperatures used in each run.

What is the maximum continuous stirring speed before torque drops off on the S-20L?

The motor delivers 1200 g·cm torque up to 600 rpm; speeds up to 1300 rpm are possible but with reduced torque for lighter viscosities.

How much heat does the 120 W motor add to the jacketed vessel during all-day operation?

The 120 W stir motor contributes a modest heat load; the double-layer jacket with circulating fluid is designed to remove reaction heat quickly, keeping the inner solution at the set temperature.
