W&H Assistina Twin MB302 – Quick ISO & RM Connectors

Fast, reliable handpiece maintenance—built for busy dental practices

The W&H Assistina Twin MB302 is a dual-chamber handpiece maintenance device that cleans internal spray channels, lubricates transmission instruments and helps dry their internal components after cleaning. With one Quick ISO connector and one Quick RM connector included, this configuration supports straight and contra-angle handpieces as well as turbine handpieces.

For practices managing a steady instrument turnaround, Assistina Twin keeps maintenance moving. Two alternating process chambers allow the next handpiece to be prepared while the previous cycle is complete—helping reduce waiting time in the reprocessing area.
