Clifton - Clifton Unstirred Water Bath

Applications & Use Cases

• Maintaining samples at a constant temperature for biological assays and chemical reactions.
• Thawing frozen samples gently and uniformly in a controlled environment.
• Incubating cell cultures and microbial samples at stable temperatures.
• Heating reagents and media to specific temperatures for laboratory procedures.
• Performing general laboratory temperature control tasks where precise stirring is not required.

Typical Specifications

Typical capacity

For this class of equipment, capacities commonly range from 5 litres to 20 litres, though smaller and larger units exist.

Temperature range

Units of this type typically offer a temperature range from ambient +5°C up to 99°C.

Temperature stability

Commonly, temperature stability for unstirred water baths is around ±0.1°C to ±0.5°C, depending on the model and controller.

Power supply

Most laboratory water baths operate on a standard 230V, 50Hz single-phase supply, suitable for UK laboratories.

Construction material

The inner tank is typically constructed from stainless steel for durability and ease of cleaning, with an outer case often made of painted mild steel or stainless steel.

Safety features

Commonly found safety features include over-temperature protection and low-level cut-off to prevent element burnout.

Frequently Asked Questions

• What is the difference between an unstirred and a stirred water bath?

  An unstirred water bath relies on convection for heat transfer, which can lead to slight temperature gradients. A stirred water bath incorporates a pump or stirrer to ensure uniform temperature distribution throughout the bath.

• What maintenance is typically required for an unstirred water bath?

• Can I use an unstirred water bath for flammable samples?

• What accessories are commonly available for these units?

• How do I ensure accurate temperature control with an unstirred water bath?
