general purpose valve, 90D

A 2mm bore grease-free, general purpose stopcock is designed primarily for use in control of fluids. Excellent for use in construction of burettes, addition funnels and non-vacuum apparatus. Valve is constructed so that only glass and PTFE come in contact with fluids. Tip design provides for semi-needle valve metering action. Sidearms are 8mm OD and sealed to barrel at a 90º angle to one another.
