Learn why you need stopcocks & valves for your laboratory glassware

Control the flow of liquid or gas with our comprehensive range of stopcocks. 1, 2, and 3-way stopcocks come in a range of bores and materials. For example, a 3-way stopcock with T-bore made of borosilicate glass. Or the modifiable 2-way stopcock with straight bore and two connections, which can also be used as a 3-way stopcock with T-shaped bore and three connections, with nuts made of glass-fibre and reinforced PTFE. Available under our stopcock range are Czako stopcocks, high vacuum stopcocks, capillary stopcocks, patent stopcocks, separating funnel stopcocks and needle-valve stopcocks. We offer stopcocks for burettes and stopcock keys, made of PTFE and DURAN® glass. 

For regulating flow and pressure, we offer a range of valves, such as pressure relief valves, 90-degree valves, high vacuum valves, ball valves and non-return valves, as well as a selection of retaining devices to assist in your laboratory work.
