Advantages and Improvements
A few years ago we at Adams & Chittenden Scientific Glass decided to re-engineer the whole cordset and connector, basing the connection on the GL45 thread, which is a standard, rather beefy thread, in common use in the chemistry and biology worlds. We designed a stopper unit using machined polypropylene and silicone, with stainless steel posts to connect to the heating coil. This has proved very effective, avoiding many of the leakage, corrosion, and disconnection problems common in the older version. Older stills having the obsolete thread and cordset can be retrofitted for the new version.
