Vacuum Flow-control Adapter,With 2mm PTFE stopcock and standard upper outer and lower inner joint.
This flow control adapter is used to control or regulate the flow of gases into a reaction system. For example, for reflux performed under an inert atmosphere, this adapter can be placed at the top of the reflux condenser and connected to the inert gas supply system .Also it can be used with single-neck flasks in order to pull a vacuum on the system. And if placed on multi-neck flasks, this adapter is connected to an inert gas supply to permit counterflow operations at the other necks.
Laboy Glass vacuum flow control adapter is made of high-quality borosilicate glass and 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.
All the jointed glassware products in Laboy are made by hand-blowing,heavy wall design,for the interchangeable joints,they are finely grounded both by machined and hand to ensure leak free.All the glass joints has a standard 1:10 taper, it can fit any glassware with joint which has the same taper and same outside diameter as long as the apparatus to which they are attached does not interfere. For example, an adapter with 14/20 male joint will fit into a 14/35 flask.
