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.
