• DESIGN----The vacuum flow-control adapter,with 2mm glass stopcock to control the flow during distillation or reaction.With standard taper male joint at bottom fit an interchangeable female joint.The 2mm glass stopcock provides on/off control with the main valve to regulate the flow into reaction system.The straight hose connection Allows for flexible tubing to be connected to apparatus for introduction of vacuum or pressure in vacuum distillation.
• DIMENSIONS----The flow control adapter is with 2mm glass stopcock,vertical 8mm hose connection, 24/40 Standard taper inner joint.The 8mm hose connection is straight at top,which can accommodate a 6mm I.D.rubber tubing..
• USE----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.
• HEAVY WALL ---The 2 neck flask is heavy-wall designed , made by hand-blowing according to ASTM E438 ,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,durable and reusable..
• 100% 90 DAY MONEY BACK GUARANTEE If you are not satisfied for any reason, simply return for a full refund, no questions asked. You have nothing to lose.Please also kindly undertand glassware is fragile, even if we pack them carefully,it may be broken during the shipment ,if you receive the items in broken status,don't hesitate to contact us ,we will arrange free replacement or full refund..

The vacuum flow-control adapter, with 2mm glass stopcock to control the flow during distillation or reaction. With standard taper male joint at bottom fit an interchangeable female joint. The 10mm hose connection is straight at top, which can accommodate a 8mm I. D. rubber tubing. 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 inlet 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.
