Water Bath Location

  • Ensure the water bath is placed on a level surface, with the mains plug and switch easily accessible.
  • While ventilation is not strictly required, Thermoline recommends maintaining 100mm of clearance on the sides and back to aid with accessibility.
  • If multiple TWBRC-24 baths are used side by side, the heat from one unit can be blown into the back of the next. To prevent this, a minimum spacing of 300mm between units is required.

Filling the Water BathThermoline Manual Image - Unistat - Water Level Indication

Water FIllingEnsure the bath is filled to at least the minimum required by the heater circulator being used. Thermoline recommends a maximum fill level of approximately 30mm from the top of the bath, which can be identified by the lip at the top.

When filling, consider the volume of the samples being placed in the bath to ensure their displacement does not cause an overflow.

Notes:

  • Never use deionised water in the water bath. It will corrode the stainless steel and will not covered under warranty.
  • If the required temperature is below 5°C, a 50:50 mixture of water and ethylene glycol is required to prevent freezing.
  • Never fill the bath with oil. The introduction of oil will result in pyrolysis (chemical decomposition by heat).
  • The water in the bath, as well as the bath itself—including the lid—can become very hot during operation.

 

 

Hose Connections

The water outlet and water inlet are both located on the top of the bath. The water outlet is identified by the ball valve. Both the outlet and inlet have a 12mm barbed fitting attached. These barbed fittings can be removed, allowing the use of a standard 12mm airline hose.

Warning WARNINGS

  • The refrigerated water bath requires ventilation for optimal performance. Keep the sides and top clear of any obstructions.

     

  • Failure to adhere to these requirements can result in improper ventilation and may void the manufacturer's warranty.

     

  • Ensure there are no blockages around the exhaust, as restricted airflow will affect proper ventilation. Keeping the exhaust clear of obstructions will help prevent operational issues.

     

  • Before use, remove all packaging, including tape, plastic bags, and foam pieces, from the refrigerated water bath.
