ZT 220 Series

ZT 220 Series

Overview

The disintegration testers of the ZT 220 series are available with 1, 2, 3 or 4 simultaneously motor driven USP/EP/JP compliant test stations with basket rack assemblies. The standard versions of these units incorporate a high-quality integrated flow-through heating system, a moulded one-piece PET water bath (can’t leak, can’t break, easy to clean) and a water bath cover.

Easy control of the unit: Set test run parameters such as run time and water bath temperature are entered via a membrane keypad with symbol keys and the actual values are then shown on large and bright LED displays. The run time counter is automatically started when the basket rack assembly is lifted into the test media.

Lift in and lift out of the baskets are performed manually, while the counting of the elapsed test duration is automatically started and stopped. On request, an alarm may be set to sound upon completion of the preset test time. Heating of the warming solution in the PET water bath is performed by an integrated flow-through heating system.
