Uniquely identified with its own serial number recorded on our product database, which includes all of its manufacturing inspection data.

Electrically tested for safety at final inspection and a test certificate enclosed in rear of the instruction book.

To verify the performance of the temperature control system digital display units undergo a factory calibration procedure which calculates the temperature values over the operating range of the equipment from 2 reference calibration points.

19. Carries the CE mark meeting the requirements of Low e and EMC Directives.

20. VoltagPowder painted body providing a durable finish and protection against corrosion and now featuring “active anti-bacterial technology”. This paint finish actively inhibits bacterial growth improving hygiene requirements as demanded by many clinical and laboratory environments. Hygienic coatings are part of a controlled approach to cleaner facilities. The Clifton range has always featured easy to wipe clean smooth paint finishes that are resistant to routine and efficient disinfection’s, however this improved coating featuring ‘active anti-bacterial’ properties provides an extra layer of defence. This new anti-bacterial paint finish is effective against major strains of bacterium including E-coli and Staphylococcus aureus, resistant strain. Within its formulation an active ingredient is a proven anti-bacterial agent bound into the coating during application and curing to the product. The efficacy of the paint finish applied to the Clifton range is maintained over time, as the anti-bacterial agent is integral within the paint finish.

Clearly visible bright status indicators

Indication of heating, over temperature alarm, timer and setting set points.

Safety

When a low liquid level is detected in the bath a “FIL” message automatically appears, with an audible buzzer and warning indicator, heating is then suspended. Once refilled, heating is restored and temperature control resumes automatically.
Over and Under temperature alarm automatically set at +4°C and –4°C about set point, providing heater cut off, visual message and indicator in alarm conditions.
Convenient push-fit and lock fittings - for secure external liquid circulation - reduces risk tubing becoming dislodged or leaking hot or cold fluids in use.

Water bath

Features a stainless steel 304 spec tank, corrosion resistant and crevice free, contained within a sturdy body zinc coated steel, powder painted exterior with a tough Anti-bacterial finish with good chemical resistance.
Supplied with removable stainless steel false base designed for good water circulation and water temperature stability.

Heating/Cooling information :

1. Cool down times are stated from ambient using 100% glycol or Lab Bath solution using DC1-300 Immersion Cooler and 22 litre tank.

2.Heat up times are stated from ambient 20°C.

3. All temperature measurements and performance claims have been carried in ambient temperature 20°C and installed correctly with adequate ventilation.

4. Using a lid is recommended

Reduce evaporation
Assist keeping samples and water free from contamination
Above 60°C or below ambient it is recommended that to achieve optimum performance the bath should be covered with a Lid - accessories below
Saves energy, reducing electricity consumption and running costs

5. With accessory DC1-300 Immersion Dip Cooler the bath can be cooled to any temperature from ambient to -20°C. The Thermostirrer provides counter heating to control the liquid in water bath at any set temperature in this range.

6. "Adaptive tune" provides instant control from start up and automatically adjusts PID values with actual temperature readings being fed into its brain until it achieves set temperature. These adjusting PID values determine heat-up rate, the load and volume of liquid producing negligible overshoot. All this happens automatically and requires no setting giving you peace of mind.
