1. Product Description
1.1 Introduction
Westlab’s Stirred Water Baths feature a digital PID temperature controller and are
designed for immersion of asks, bottles and racks in an accurate temperature
environment throughout the water bath. The stainless-steel tank is housed in a sturdy
outer case and is supplied complete with a stainless-steel shelf which provides even
water circulator and temperature stability.
The painted surfaces feature a tough antibacterial nish with good chemical resistance.
Easy to use controls which are wipe clean and have an antibacterial nish. Immersed
components are corrosion resistant. The ecient stirrer is quiet in use and provides
excellent temperature stability. Indication of heating, over temperature alarm and
timer running.
When a low liquid level is detected a “FILL” message automatically appears and heating
is suspended. Once relled, heating is restored, and temperature control resumes
automatically. Over and under temperature alarms automatically protect samples
in the water bath.

3. Safety Precautions & Maintenance
3.1 Safety Precautions
1. This product is designed for laboratory use only. Always follow good laboratory
practice.
2. Fill the tank prior to connection to electrical supply.
3. Use caution when topping up or draining the tank. If this product is not used in
accordance with these instructions, then basic safety protection may be affected.
4. The mains supply cord tted to this product is heat resistant and should be
replaced with an equivalent type by a qualied electrician.
5. Ensure that the power supply has a safety earth (ground) terminal.
6. Ensure that the mains switch, and power supply connector are accessible during use.
7. Before using any cleaning or decontamination method please refer to the
Maintenance section to ensure the proposed method will not damage the unit.
8. Connect only to a power supply with the corresponding voltage to that specied on
the rating label positioned on the rear of the unit.
9. Do not block ventilation slots during use and always follow installation instructions.
10. Ensure substances being heated present no risk of a hazard (explosion, implosion,
or release of toxic or ammable gases) or that these have been addressed. When
heating substances where liberation of gases occurs, suitable extraction should
be used.
11. Use only liquids specied within this Instruction Manual within their specied
temperature range.
12. Drain all liquid before moving the water bath.
13. We recommend using a lid above 60˚C. Take care when lifting the lid as steam and
hot vapours can cause scolding.
14. Use a thermometer to check the temperature - do not touch the liquid.
Liquid Levels:
Always ensure that the water bath is disconnected from the electrical supply before
lling or emptying the unit.
Tank Capacity Minimum Liquid Level Maximum Liquid Level

Suitable Liquids:
Operating temperatures and recommended liquid options are as follows:
Temperature Range Options
- 20°C to Ambient 100% Heat Transfer Liquid
100% Car Antifreeze (Ethylene Glycol)
Ambient to + 99°C Distilled Water
Virkon Dissolved in Distilled Water: Proven ecacy
against bacteria (including micro bacteria), viruses,
spores, and fungi in a variety of independent tests
using different protocols.
Heat Transfer Liquid
Note: For temperatures above 60°C or below room temperature, the water bath should be covered
by a lid or layer of polypropylene spheres to achieve optimal performance.
3.2 Maintenance
Please ensure that the washing agent and sanitising agent are BSI accredited and
approved by the H&S department for use on laboratory equipment and stainless steel
within your laboratory.
ATTENTION: Disconnect the Bath from the Power Supply Prior to Cleaning
Basic Cleaning Procedure:
The stainless-steel crevice free tank should provide years of valuable service
and is resistant to chloride containing solutions, but it is important to avoid high
concentrations of halogens- particularly chloride. Halogen deposits may show as
rust which can be cleaned off with nitric acid (10%) on a cloth. WEAR PROTECTIVE
EQUIPMENT!
The water bath should be emptied at the end of each day, then for interior surfaces:
• WASH • RINSE • DRY •
For algae and slime control in water baths, please use Water Bath Conditioner AR.
Occasionally small spots may occur in the bath which resemble rust. These are usually
small ferrous particles which have oxidised. Using a stainless-steel cleanser such as
Bar Keepers Friend® will remove these marks as well as mineral deposits.
Exterior Anti-Bacterial Painted Surfaces:
The water bath should be cleaned at regular intervals by wiping external surfaces with
a cloth or sponge soaked in warm water with a mild detergent.
ATTENTION: Do Not Use Strong Solvents or Solutions Containing Chlorinated
Hydrocarbons, Esters, Ketones or Abrasive Cleaners as this may Damage the Built-In
Antibacterial Properties.
