VACCUM TAKE-OFF ADAPTER SHORT STEM
Starting at $13.94
This short stem 105DGR bent take off adapter with sealed-in drip tip is used to connect a condenser to a receiving flask for vacuum distillation,with hose connection.
The adapter with top outer joint and bottom inner joint,used with condensers and flasks with joints. laboy glass are all made of high-quality borosilicate glass and made by hand-blowing to ensure uniform wall thickness.
- The top joint is at 105 degree bent, ideal for receiving a downward liebig or west condenser.
- Short stem design, with sealed in drip tip,guide the condensed liquid into the receiving flask or a separatory funnel.
- With standard joints at top and bottom providing a leakfree and easy way to join all the lab glassware required in one set-up.
- With 10mm hose connections,in a simple steam or fractional distillation, this hose connection is open to air ,in a vacuum distillation,the hose connection accepting 3/8” ID flexible heavy-wall vacuum tubing to a trap,vacuum source and manomete for vent or introducing vacuum or gas into the reaction system.
Material and workmanship：
- The jointed vacuum take off adapter is made of high quality borosilcate glass 3.3 having very low coefficients of thermal expansion and making more resistant to thermal shock,all the glassware supplied by laboy are annealed at 800 degree Celsius ,can be heated directly in an open flame and can withstand typical laboratory thermal variations in chemistry processes like heating and cooling.
