Reaction vessels & jacketed vessels

A single-walled vessel is heated or cooled from outside, in a bath or heating mantle. In a jacketed vessel, thermostat fluid flows through the outer jacket, which gives precise and even temperature control, also for exothermic reactions. A jacketed vessel needs a circulator to pump the fluid. Check the temperature range of the circulator against your reaction. Insulated hoses limit heat loss. See circulators, chillers and thermostats. For a quote or a second opinion, write to sales@luminixhealth.com.

Vessel, lid, sealing ring and quick-release clamp must all share the same DN size. Once that is fixed, choose the number and type of necks on the lid, either ground joints or screw threads, for stirrer, condenser and thermometer. Check the DN size on the product page. Write down the size before ordering spare parts. A worn sealing ring is best replaced at the same time. Matching parts are in ground joint glassware and condensers.

Place a sealing ring between vessel and lid, and close the joint with a quick-release clamp in the same DN size. A PTFE or PTFE-coated ring suits aggressive media; silicone is fine for general use. Check the ring for damage before each assembly, as a worn seal leaks vapour. Do not overtighten the clamp. Sealing products are in grease, boiling stones and sealants. Unsure which one fits? Ask sales@luminixhealth.com.

An overhead stirrer drives a stirring shaft through a stirrer guide in the centre neck of the lid. The stirring element, such as an anchor, propeller or turbine, is chosen by viscosity and the mixing you need. Make sure shaft length and diameter match stirrer chuck and guide. Start stirring slowly. See overhead stirrers and stirring shafts, propellers and impellers. Need advice for your set-up? Mail sales@luminixhealth.com.

A reaction vessel is the flask a synthesis actually runs in, sometimes jacketed so a fluid can heat or cool the wall. The joints, the working volume and the jacket connections are the specification. It is not a storage bottle.

A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
