Excellent general purpose bath suitable for a wide variety of laboratory applications
• Easy-to-use microprocessor controller
• Three preset temperature buttons for rapid set point changes
• 28 liter capacity, hinged see-through cover
• External circulation capability
Designed specifically for coliform testing, water bath features standard control and incorporates three preset temperature buttons which can be used to rapidly change to common coliform test temperatures (44.5, 45.5, 41.5 and 35.0°C) or other temperatures from ambient +5 to 150°C. Over-temperature cutoff is user-adjustable. Bath temperature is displayed on a bright LED readout. A quick press of a knob displays set point and also selects temperature (°C or °F). Bath also features low-liquid cutoff feature for added protection.
For operational convenience, unit is equipped with a tilting, see-through polycarbonate cover which drains back into the bath when opened. An integral 2-speed (simplex) pump can be used to circulate the bath liquid to other instruments using a closed loop configuration. All wetted componets are corrosion-resistant 300 stainless steel. The outer case is protected with a durable, easy-to-clean epoxy powder coating.
This circulating bath is specifically designed for the following Coliform tests:
1) APHA, AWWA, WEF and EPA fecal coliform determination at 44.5°C as specified in "Standard Methods for the Examination of Water and Wastewater" (19th Edition 1995). The membrane filter method of MPM method can be used.
2) AOAC determination of E. coli at 45.5°C.
3) APHA, AWWA, WEF 7-Hour Fecal Coliform test at 41.5°C.
4) Defined Substrate Technology™ tests for E. coli and total coliform at 35.0°C.
