DISPENSING
NBD Bi-component Dispensing Head

Contax Ltd - UK

This dispenser was developed specially for dispensing and mixing small quantities of bi-component substances. Versions are available for volumetric dispensing either with or without numerical control. Each component is dispensed separately into a static or dynamic mixing cartridge. In the case of polymerisation, the disposable mixing cartridge can be rapidly replaced. The mixing cartridge is a plastic chamber fitted with a rotary spindle carrying a mixing paddle. The micro dispenser uses a piston and cylinder made from ceramic material this gives the pump a very long life. The latest manufacturing techniques and close tolerances mean the MTA dispensers can achieve statistical repeatability levels around one tenth of a percent. This dispenser can be used with dense, sticky substances right through to thin, fluid substances.
