Product Details Supplier Info More products

Lee Products has introduced a hard-seat VHS micro-dispense valve designed to ensure the precise, repeatable and non-contact dispensing of fluids in the nanolitre to microlitre range.

The valve features a precision Zirconia ball and seat. This ensures resistance to aggressive fluids such as dimethyl sulphoxide, which would normally attack and degrade standard elastomer-type materials.

It is designed for two-way, normally closed operation. Wetted materials comprise stainless steel, PEEK and Zirconia.

The valve can be fitted directly over 96-well plates and can be connected to the company’s 062 Minstac fittings and press-on tubing. The 062 Minstac outlet can be used with Lee 062 Minstac tubing or atomising nozzles.
