5.0 Operating procedures
5.1 Operation
5.1.1 Water level
Ensure that the baths are used with the shaking tray in place and that the water always
covers the tray. The maximum water level should not be higher than the swage line
around the top of the bath (around 2.5cm from the top). These criteria apply both when
there are no vessels in the bath and with the maximum contents. Note that water level
may have to be reduced at higher shaking speeds to prevent spillage and stalling of the
mechanism.
Avoid letting the bath run dry. In the event this does happen, the safety cutout will trip
and disconnect the heater. If this does happen, unplug the bath and have the cut-out re-
set by a competent person.
5.1.2 Operation above 60°C
The lid must be used above 60°C to maintain proper temperature control and to ensure
that the water temperature reaches the set point
The lid will also prevent excessive evaporation that requires the bath to be filled more
often and will save energy
5.1.3 Use as a thermostatic bath without shaking
If the shaking trolley and drive magnet are lifted out, a shaking bath can be used as a
simple thermostatic bath. When used in this way, if flat bottomed vessels or objects are
to be placed in the bath, always use a raised base tray (optional accessory) to avoid
damage to the under-tank heater.
5.1.4 Emptying the baths
Before emptying any bath allow the water temperature to fall to a safe level and take
reasonable precautions to prevent accidental spillage.
Drain taps are included in both baths to allow convenient emptying. These baths should
be emptied using the drain tap prior to moving. To empty the bath using the drain tap,
push the supplied drain insert into the drain tap (see picture below). Note that the water
will begin to empty from the bath as soon as the drain insert is fully engaged. A length of
hose can be added to the barbed end of the drain insert if required.

The maximum speed for a particular application will depend on number and size of
vessels, and the depth of the water. The shaking trolley is driven by a drive magnet
under the tank, magnetically coupled to the trolley through the tank. As the speed is
increased a point is reached where the magnetic coupling de-latches, causing the trolley
either to move erratically or to stop.

protection thermostat will maintain the water in the bath at a temperature a few degrees
above the set temperature and with greater fluctuations. The display will cycle between
this happens, first check that the sample protection thermostat is not set to a lower
temperature than the primary control system. If that is not the reason, the bath can
continue to be used without compromising the safety of persons or the surroundings until
current work is completed. However, it is recommended to have the bath checked by a
competent person as soon as conveniently possible.

7.0 Technical Tips
7.1 Which water should you use in your bath?
For the long-term reliability of water baths it is important to use oxygenated water that is
free from ions and minerals that can cause corrosion of stainless steel. We recommend
the use of distilled water and de-ionised water from modern ion exchange systems that
do not use salt back flushing to regenerate the ion-exchange cartridges.
Stainless steel is protected from corrosion by a layer of chromium oxide. If the layer is
damaged, oxygen present in water can reform the oxide layer. If the water is still or de-
oxygenated, and the oxide layer is damaged, ions can corrode the stainless steel tank. If
a water bath has been unused for some time, or water boiled, we recommend changing
to fresh distilled water or correct de-ionised water.
Water normally contains calcium or magnesium ions. De-ionised water has most ions
removed as indicated by its conductivity level; the purer the water the lower the
conductivity. It is important to use only de-ionised water from an ion exchange system
with replaceable cartridges. Do not use de-ionised water generated from an ion-

EN
exchange system that incorporates a salt back-flush system to regenerate the ion-
exchange resin as this can leave sodium ions that are very corrosive to stainless steel.
7.2 How to prevent rust in water baths
Most Grant tanks, as well as immersed parts, are made from type 304 stainless steel, an
extremely versatile general purpose grade of stainless steel. It is the excellent forming
characteristic that has made this grade dominant in the manufacture of laboratory and
industrial water baths, as well as domestic sinks and saucepans. Type 304 stainless
steel is highly suitable for applications where hygiene is important; it exhibits good heat
resistance and excellent resistance to corrosion.
However, despite resistance to general surface corrosion, stainless steel is susceptible to
specific types of corrosion, in particular pitting (small pin hole style corrosion) and stress
corrosion cracking. It can also undergo general corrosion in specific environments, such
as one containing hydrochloric or sulphuric acids.
Stainless steel is protected by its high content of alloying elements, primarily chromium
and nickel. Chromium is the most important with respect to corrosion resistance,
although the nickel assists in allowing the chromium to do its job. The chromium forms an
oxide layer on the surface of the steel, which inhibits further oxidation. This layer adheres
extremely well to the metal substrate, but it is essential that it remains intact, and must be
protected from various forms of damage.
If the surface chromium oxide layer becomes damaged, oxygen present in water can
partially reform the oxide layer, so it is advisable to ensure that water is always fresh and
well oxygenated. Baths that will be out of use for an extended period should be emptied,
and all moisture should be wiped from the bottom of the tank.
In some cases a brown layer may appear on the surface of a stainless steel tank. In most
of these cases this is not rust, but it may be a surface deposit of minerals from the local
water supply, or ferrous particles or salts that have fallen into the tank. These surface
deposits can usually be removed by using a household cleaner such as Duraglit or Silvo
metal polish.
7.3 How to prevent algae and bacteria?
Water baths provide the ideal environment for the growth of micro-organisms. If left
uncontrolled the growth of these organisms can result in a range of serious problems and
health risks from pathogenic bacteria.
The growth of algae on the surface of parts will cause biofouling which can reduce
performance.
Micro-organisms that produce acidic metabolic by-products can cause bio-corrosion by
depolarisation of metal surfaces.
There are a number of biocides available on the market.
