What is the difference between an unstirred and a circulating bath?

An unstirred bath relies on convection for temperature distribution, suitable for less critical applications. A circulating bath, like the TXF200, uses a pump to ensure uniform temperature throughout the bath and can also circulate fluid to external equipment.

Can this unit be used for external applications?

Yes, the TXF200 is designed for both internal and external circulation, making it suitable for maintaining the temperature of external devices or reaction vessels.

What type of fluid should be used in a circulating bath?

For temperatures up to 100°C, deionised water is commonly used. For higher temperatures or specific applications, silicone oils or other heat transfer fluids may be required. Always consult the manufacturer's guidelines.

Is calibration required for a used circulating bath?

While the unit is described as in working condition, for applications requiring high precision or regulatory compliance, re-calibration by a qualified technician is strongly recommended to ensure accuracy.

What maintenance is typically involved with a circulating bath?

Regular maintenance includes cleaning the bath reservoir, checking fluid levels, and inspecting the pump and heating elements for wear. It is also important to use appropriate bath fluids to prevent corrosion and algal growth.

Typical context for this category of equipment. Always confirm specifics with the seller.

Precise temperature control for chemical reactions and biological assays.
Calibration of sensors and other temperature-sensitive instruments.
External circulation to maintain stable temperatures in refractometers, viscometers, or jacketed vessels.
Sample preparation requiring consistent heating or cooling.
Quality control testing in pharmaceutical and research laboratories.

Temperature range: Typically ambient +5°C up to 100°C, with some models extending to higher or lower temperatures with cooling.
Temperature stability: For this class of equipment, stability is commonly ±0.01°C to ±0.05°C.
Circulation pump flow rate: Units of this type typically offer flow rates from 10 to 20 litres per minute for effective external circulation.
Bath volume: Circulating baths in this category commonly have volumes ranging from 5 to 20 litres.
Power supply: Typically single-phase 230V, 50Hz for the UK market, with power consumption varying based on heating capacity.
Heater power: Commonly 1000W to 2000W, influencing heat-up times and maximum temperature.
Display: Digital display for set and actual temperature, often with intuitive controls.

An unstirred bath relies on convection for temperature distribution, suitable for less critical applications. A circulating bath, like the TXF200, uses a pump to ensure uniform temperature throughout the bath and can also circulate fluid to external equipment.

Water baths and heating baths are generally valued in laboratory and biotech settings for their reliability and precision temperature control. When purchasing used units, buyers typically prioritize checking heating uniformity, control system functionality, and tank condition to avoid corrosion issues. These devices are known for their durability and long operational lifespan when properly maintained. Industry sentiment favors established brands known for consistent performance and availability of spare parts.
