Description
Clifton® Digital Water and Oil Heating Circulators designed for external circulation of temperature-controlled water and heat transfer fluids in a closed circuit or maintaining a stable temperature environment in the bath for the immersion of flasks/bottles/racks.

Thermocirculator can be fitted to water baths, tanks and containers using accessory Mount Bracket.

The Thermocirculator is robustly constructed from stainless steel for durability. Painted surfaces feature a tough anti-bacterial finish with good chemical resistance. Easy to use controls that wipe clean and have an anti-bacterial finish. Immersed components are corrosion resistant. Quiet running in use and providing excellent water temperature stability. Indication of heating, over temperature alarm and timer running.

When a low liquid level is detected a “FiLL” message automatically appears and heating is suspended. Once refilled, heating is restored and temperature control resumes automatically.

Over and under temperature alarms automatically protect work in the water bath, providing heater cut off, visual message and indicator. Additionally a Safety Experiment protector can be set just above desired working temperature protecting your work.

Thermocirculator pump comes with convenient push-fit and lock fittings on both inlet and outlet ports for secure external water circulation.
Controls
Featuring bold LED display of measured temperatures in real-time, increments of ±0.1°C, using precision PID temperature control. Setting for water temperature only or combination of temperature and time. Timer setting variable in 1-minute increments from 00:01 [hh:mm] to 99:59 [hh:mm] with “end” message on completion-timed period. Settings retained even after turning the unit off.

Easy to use splash proof controls, touch keypads for setting time and temperature values with indicators for heating, over temperature alarm and timer. Bold digital LED display.

Thermocirculator can be set to run at a set temperature or commence the timer once the water reaches set temperature.

Features auto setting over and under temperature alarm protecting your work at set temperature.

A Safety Experiment protector can be set just above desired working temperature protecting your work. Every unit undergoes a factory calibration at two temperatures for validation.
Safety Features
Features a low liquid level float switch, which ensures heating, is switched off if the liquid falls below the recommended level - display will show “FiLL”. Heating is switched off but stirring continues. To reset carefully top up the liquid to the recommended level.

The under/over temperature alarm is automatically set 4˚C above and 4˚C below set temperature. When in alarm condition the indicator illuminates and actual bath temperature is shown, if bath is over temperature both heating and stirring are switched off. Once liquid temperature has fallen or risen above/below the alarm setting the indicator clears and actual bath temperature is shown.

Class 2 protection features a Safety Experiment protector can be set just above desired working temperature protecting your work.

Stainless Steel Hinged Gable Lid to suit 14 Litre Baths

1. The Gable lid has been designed allowing full use of whole width of a Clifton water bath with the lowest height of the gable being 45mm above the bath. This unique feature means test tube racks or flasks can be placed across the whole width of the bath without fouling the lid maximising the bath working area.

2. Designed with customer in mind ensuring where condensation accumulates in use there are no drip points which could spoil work in open flasks in your Clifton water bath.

3. Where an accessory TC-1 Thermometer is used the temperature can be read from the thermometer with the lid in place.

4. Lid fits into the tank ensuring all condensation runs back into the bath and not down the side onto your bench top.

5. The hinged lid has the added advantage where bench space is limited, the lid hinges back to the vertical position to access the bath where as a conventional lid requires lifting off the bath and placing on your bench top.

Description
Clifton® Digital Water and Oil Heating Circulators designed for external circulation of temperature-controlled water and heat transfer fluids in a closed circuit or maintaining a stable temperature environment in the bath for the immersion of flasks/bottles/racks.

The stainless steel tank contained within a sturdy outer case and supplied complete with a stainless steel shelf all providing good water circulation and temperature stability.

The Thermocirculator is robustly constructed from stainless steel for durability. Painted surfaces feature a tough anti-bacterial finish with good chemical resistance. Easy to use controls that wipe clean and have an anti-bacterial finish. Immersed components are corrosion resistant. Quiet running in use and providing excellent water temperature stability in the bath. Indication of heating, over temperature alarm and timer running.

When a low liquid level is detected a “FiLL” message automatically appears and heating is suspended. Once refilled, heating is restored and temperature control resumes automatically.

Over and under temperature alarms automatically protect work in the water bath, providing heater cut off, visual message and indicator. Additionally a Safety Experiment protector can be set just above desired working temperature protecting your work.

Thermocirculator pump comes with convenient push-fit and lock fittings on both inlet and outlet ports for secure external water circulation.

Controls
Featuring bold LED display of measured temperatures in real-time, increments of ±0.1°C, using precision PID temperature control. Setting for water temperature only or combination of temperature and time. Timer setting variable in 1-minute increments from 00:01 [hh:mm] to 99:59 [hh:mm] with “end” message on completion-timed period. Settings retained even after turning the unit off. Easy to use splash proof controls, touch keypads for setting time and temperature values with indicators for heating, over temperature alarm and timer. Bold digital LED display. The water bath can be set to run at a set temperature or commence the timer once the water reaches set temperature. Features auto setting over and under temperature alarm protecting your work at set temperature. A Safety Experiment protector can be set just above desired working temperature protecting your work. Every unit undergoes a factory calibration at two temperatures for validation.
Safety Features
Features a low liquid level float switch, which ensures heating, is switched off if the liquid falls below the recommended level - display will show “FiLL”. Heating is switched off but stirring continues. To reset carefully top up the liquid to the recommended level.

The under/over temperature alarm is automatically set 4˚C above and 4˚C below set temperature. When in alarm condition the indicator illuminates and actual bath temperature is shown, if bath is over temperature both heating and stirring are switched off. Once liquid temperature has fallen or risen above/below the alarm setting the indicator clears and actual bath temperature is shown.

Class 2 protection features a Safety Experiment protector can be set just above desired working temperature protecting your work.

Stainless Steel Hinged Gable Lid to suit 22 Litre Baths

1. The Gable lid has been designed allowing full use of whole width of a Clifton water bath with the lowest height of the gable being 45mm above the bath. This unique feature means test tube racks or flasks can be placed across the whole width of the bath without fouling the lid maximising the bath working area.

2. Designed with customer in mind ensuring where condensation accumulates in use there are no drip points which could spoil work in open flasks in your Clifton water bath.

3. Where an accessory TC-1 Thermometer is used the temperature can be read from the thermometer with the lid in place.

4. Lid fits into the tank ensuring all condensation runs back into the bath and not down the side onto your bench top.

5. The hinged lid has the added advantage where bench space is limited, the lid hinges back to the vertical position to access the bath where as a conventional lid requires lifting off the bath and placing on your bench top.

6. With continuous sampling work a conventional lid has to be removed frequently to access samples/work this hinged lid is designed with this in mind.

7. The Lid hinges back to just over vertical position as in image above.

8. Using the 'Side lifting handle' minimises the risk of hot steam rising from bath reaching your hand in use.
