Clifton NE4-SB Universal Heated Thermostirrer
Clifton NE4-SB Universal Heated Thermostirrer
A versatile digital thermostirrer designed to provide accurate heating, controlled stirring and stable temperature conditions in a wide range of laboratory tanks and vessels.
Universal Heated Thermostirrer
The Clifton NE4-SB Universal Heated Thermostirrer provides a flexible solution for laboratories requiring controlled heating and water circulation without purchasing a dedicated complete water bath.
The unit is designed to fit onto a wide range of rectangular or circular tanks and vessels, making it particularly useful where existing laboratory vessels need to be converted into a controlled heated and stirred bath.
The NE4-SB uses a precision digital PID temperature controller to regulate the bath temperature while providing even water circulation and temperature stability.
The NE4-SB can be fitted to a variety of tanks and vessels with a diameter of 30 cm or more, subject to the specified mounting requirements.
Universal Tank Compatibility
The NE4-SB is designed to be fully compatible with a range of laboratory tanks and vessels, including rectangular and circular containers.
The double-clamp mounting system accommodates tanks with a maximum wall thickness of 40 mm. Suitable tank diameter is 30 cm or greater.
Rectangular Tanks
Suitable for compatible rectangular laboratory vessels, providing controlled heating and circulation without requiring a dedicated bath body.
Circular Vessels
Can also be fitted to suitable circular vessels with a diameter of 30 cm or greater.

Digital PID Temperature Control
The NE4-SB incorporates a precision PID digital temperature controller with a bold LED display. The display shows the actual or set temperature with a resolution of 0.1°C.
The temperature range is ambient +5°C to 99°C, with a sensitivity of ±0.05°C.
Temperature and time settings can be retained in memory after the unit has been switched off, helping simplify repeated laboratory procedures.
Even Water Circulation
The integrated stirring system provides continuous water movement to support even temperature distribution and stable conditions throughout the working vessel.
This makes the NE4-SB particularly useful where temperature consistency is important across a larger volume of liquid.
Safety & Protection
Automatic Temperature Protection
The under- and over-temperature alarm is automatically set at 4°C above and 4°C below the selected set temperature.
When an over-temperature condition occurs, heating and stirring are switched off until the temperature returns to the permitted range.
Low-Liquid-Level Protection
A low-liquid-level float switch helps protect the heater by suspending heating when the liquid falls below the recommended level. The display indicates the low-level condition so the vessel can be safely topped up.
Timer Function
The NE4-SB includes a variable timer from 00:01 to 99:59 hh:mm. A visual indicator and audible end message signal completion of the timed period.
This allows the unit to be used for both continuous temperature control and timed laboratory procedures.
Optional Cooling
For applications requiring temperatures below ambient, the optional Clifton DC1-300 Immersion Cooler can be used with the NE4-SB.
With the appropriate cooling arrangement, the system can provide temperature control from ambient down to approximately -20°C, subject to tank capacity and the recommended operating conditions.

Energy Efficiency
The manufacturer states an indicative energy consumption of approximately 0.5 kWh at 37°C. Actual consumption varies according to ambient temperature, ventilation, vessel configuration and loading.
For higher-temperature applications, the manufacturer recommends using a suitable lid or layer of polypropylene spheres to reduce evaporation, contamination and unnecessary heat loss.
Construction & Quality
The NE4-SB features durable construction with stainless-steel immersed components and painted surfaces incorporating an anti-bacterial finish with good chemical resistance.
The controls are designed to be easy to use and wipe clean, making the unit suitable for regular laboratory environments where cleanliness and durability are important.
Factory Calibration & Testing
Before leaving the factory, each water bath is identified with a unique serial number and undergoes factory calibration. The control is adjusted to a known traceable value and the unit is electrically safety tested during final inspection.
A test certificate is supplied with the instruction documentation.
