GL38 to GL45 Adapter (4-L to Glassware Cap)
thingiverse
------UPDATE 26Apr2020 -------- The model has been updated based on testing and requests. 1 - There is now a better grip around the bottom of the model. It is much easier to twist on and off now. 2 - The threads have been re-worked, and are much smoother. They fit perfectly with the GL45 and GL38 threads. 3 - There has been an addition of material on the top to allow for HPLC line inserts and caps to fit. now you can put the caps from the instruments straight onto this adapter and get a great seal. -------------------------------------------- Convenient adapter for 4-L glass reagent bottles to your typical GL45 caps. First use is pretty tight, I would recommend that you break it in a little before use by screwing it on to a glass bottle and capping it to make use a little easier. For organic solvents, don't use PLA, ABS, or any other plastic that cannot withstand organics. Use polypropylene or Nylon.
