A new Hard Seat VHS Micro-Dispense Valve which offers precise,repeatable,non-contact dispensing of fluids in the nanolitre to microlitre range,is a recent addition to Lee Products established range of VHS solenoid valves.
This option features a precision Zirconia ball and seat instead of a traditional elastomeric seal which ensures resistance to aggressive fluids such as DMSO(Dimethyl Sulfoxide).These,and other'aggressive fluids',would normally attack the'standard'elastomer type materials used in other types of less durable micro-dispense valves.
The Hard Seat VHS valve's small size and weight(45.2mm max length,5.6mm diameter and 10 grams)means it can be fitted directly over 96 well plates.The valve is designed for 2-way,normally closed operation and the wetted materials comprise stainless steel,PEEK and Zirconia.
The valves feature a number of port configurations to facilitate quick and convenient connections to Lee's 062 MINSTAC fittings and press-on tubing.The 062 MINSTAC outlet can be used with Lee 062 MINSTAC tubing or atomising nozzles.Custom configurations and voltages are also available to suit specific applications.
