Calibrex dispensers are factory calibrated, but can be easily recalibrated by means of a dedicated adjustment screw. Disassembling / reassembling is facilitated by the limited number of well-connected parts - no tool needed. Key elements such as valves, plunger, barrel and delivery jet can be removed in seconds for cleaning. Special attention is paid to component materials, providing for long instrument life. Parts coming in contact with the liquid flow are chemically inert. A protection sleeve reduces risk of barrel breakage and spilling. Delivery jet cap prevents liquid dropping.
