Description
VAK 3 3'' Victaulic coupling with EPDM gasket is a mechanical connector designed for joining two reactor blocks in series in laboratory process setups. The 3-inch Victaulic-style coupling provides a secure, serviceable interface between matched reactor modules, while the integrated EPDM gasket supports a reliable seal under typical laboratory fluid-handling conditions. This configuration is intended where modular reactor trains must be linked quickly without permanent welding or complex flange work, simplifying assembly, maintenance and reconfiguration of process lines. Supplied as one package, the coupling suits research, pilot-plant and technical laboratories that operate Bandelin reactor systems or compatible Victaulic-connected blocks. The EPDM sealing element is selected for chemical compatibility appropriate to many aqueous and mild process media used in such equipment. Mention of manufacturer Bandelin appears here only as the source of this VAK 3 accessory. Use the coupling wherever series connection of two reactor blocks is required for continuous or multi-stage laboratory reactions, ensuring dimensional match to the 3'' Victaulic interface on the blocks.

Questions about SONOREX TECHNIK TW 75 Transport cart
What is this article?
SONOREX TECHNIK TW 75 Transport cart is the article on this page. Luminix Health distributes Bandelin for laboratory use. It sits in Reaction vessels & jacketed vessels, inside Beakers & flasks, in Labware.
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.
Which category should I open next?
The category is Beakers & flasks. The sub-category is Reaction vessels & jacketed vessels. The catalogue is Labware.
