Clifton™ Digital Water and Oil Circulator with 14L Tank and Shelf

Clifton digital circulating baths are designed for circulation of temperature controlled water or heat transfer fluids in a closed circuit or for maintaining a stable temperature environment in the bath for the immersion of flasks, bottles and racks.

Clifton circulating baths are constructed using durable stainless steel, painted surfaces are powder coated with tough anti-bacterial finish with good chemical resistance. Easy to use controls that wipe clean also 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.

This range features the ability to pump temperature controlled liquid around a closed circuit. Featuring a circulation pump with the capacity of 10 litres per minute.

In addition to circulating around a closed vessel, this range has the capability of operating up to 130˚C. 

3 Year Warranty

The NE4-HT Series comes with a 3 year warranty as standard, we also offer free advice and support for our baths.

MADE IN GREAT BRITAIN

The NE4-HT Series is made here in Great Britain with the highest quality of materials.

Capable of external circulation

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.
• A second safety device can be set just above the working temperature protecting samples.

Energy Consumption

0.5kWh @ 37°C

The lower the figure, the less energy used. Information supplied for size and range comparison, guidance only and measured consumption at set point. Please remember that the energy consumption may vary due to factors such as location, ventilation, ambient temperatures and loading.

Controls

Featuring a bold LED display of measured temperatures in real-time and in increments of ±0.1°C, using a precision PID temperature controller. 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 of the timed period. Time and temperature settings are retained in the memory, even after the unit has been turned off.

Easy to use controls, utilising touch keypads for setting time and temperature values with indicators for heating, over temperature alarm and timer.

The heater unit can be set to run at a set temperature or commence the timer once the water reaches set temperature. Every unit undergoes a factory calibration at 37°C and 85°C for validation.

Heating/Cooling Information

For cooling a liquid bath use an accessory immersion cooler DC1-300 refer to Accessories. Where bath temperatures are below ambient we recommend a mix of glycol and water. We also recommend a lid or layer of spheres for insulation. The water bath should be used in ambient temperature 20°C. For liquid temperatures above 60°C we recommend that an accessory lid or layer of spheres are used for optimum performance. This will reduce evaporation and a lid will keep the samples and liquid free from contamination. Optimum performance saves energy by reducing electricity consumption and running costs.

ACCESSORIES

Stainless Steel Gable Lid

Clifton stainless steel gable lids help reduce evaporation, assist in keeping samples in a water bath free from contamination and save energy. These stainless steel gable lids with a high profile allow extended use of the bath, right into the edges of the tank. No drip points to contaminate samples whilst the lid design ensures all condensate returns back into the bath. Insulated handles for safe use.

Stainless Steel Flat Lid

LD4 series lid, completely manufactured from bright polished stainless steel with a large insulated lifting handle. Above 60°C or below room temperature it is recommended that to achieve optimum performance the bath should be covered with a lid.

Push Fit and Lock Insulated Hose 1m length x 6mm dia.

Flexible polyurethane tubing for connecting to inlet and outlet ports on Clifton circulating water baths.

Notes

Stainless Steel Test Tube Racks

Laboratory test tube rack, stainless steel 304 spec 18/8 non-magnetic, bright finish. Supplied flat packed ready for assembly. Can be cleaned with detergents, ultrasonics or autoclaved. Durable and stable in use with looped handles for easy retrieval from hot water baths.

• NE4-8HT = 1 rack
• NE4-14HT = 3 racks
• NE4-22HT = 5 racks

Stainless Steel Raised Shelves

The raised shelf provides a reduced liquid depth for shallow vessels in NE4 series water baths. Simple solution for placing shallow vessels in a stirred bath. Manufactured from stainless steel. The raised shelf is perforated to allow free circulation of water. Can be easily removed and cleaned.

Immersion Dip Cooler

Designed to be used in conjunction with a Clifton stirred or circulating water bath, the DC1-300 features a flexible 900mm long pipe. When placed through the aperture on the top of the bridge unit the stainless-steel cooling coil naturally stands in the corner of any Clifton NE4 stirred or circulating water bath. This maximises the working area within the bath without sacrificing the working area.

The immersion cooler runs continuously providing counter cooling with the bath providing temperature control from ambient to -20°C (subject to bath capacity). Always cover the water bath with a lid or BP0368 polypropylene spheres. This reduces energy losses by up to 70%. Doubling this layer of polypropylene spheres improves this further.
