Low-head, high-head & cleaning position

ERWEKA’s dissolution testers offer two different operating modes which differ by the position of the head, and a third position for cleaning.

Low-head operating mode (LH)

The low-head mode is the standard mode and usually comes in conjunction with a system configuration with automated sampling station (ASS-8). Benefits are the closed vessels and therefore low evaporation.

High-head operating mode (HH)

The high-head mode is best used for manual testing and manual sampling. To reduce evaporation, vessels are covered with a cover. Manual sampling is easier in high-head mode. Longer shafts have to be selected on purchasing for high-head mode.

Cleaning position

The cleaning position is the upmost position of the dissolution testers’ head. It makes cleaning effortless and easy.
