Cleaning
General
Important - please follow these instructions to avoid possible damage to
the unit, otherwise affecting its performance and warranty.
Always disconnect the product from the electrical supply before
cleaning.
Cleaning External Painted Surfaces featuring “Anti-bacterial Paint Finish”
The water bath should be cleaned at regular intervals wiping external surfaces with a cloth or sponge
soaked in warm soapy water with a mild detergent. All surfaces should be cleaned using a soft cloth or
sponge.
Do not under any circumstances use strong solvents or solutions containi
ng Chlorinated Hydocarbons, Esters, Ketones or abrasive cleaners or polish
on the paint finish otherwise it damages the built
in anti-bacterial properties.
All painted surfaces on Clifton range products features an “Anti-bacterial
paint finish” identified with this authenticating logo on the unit.
This “Anti-bacterial paint finish” inhibits the growth of bacteria. It has been
tested by independent specialist test houses such as the Law Laboratories (in
the UK) using internationally recognized test methods and proven to be effec-
tive versus a wide range of bacteria species including Escherichia coli and
Staphylococcus aureus (MRSA).
We recognise hygienic coatings are part of a controlled approach to a cleaner
working environment. Within its formulation an active ingredient with proven anti-bacterial properties
is bound into the paint finish. The efficacy of the paint finish applied to the Clifton range is maintained
over its lifetime, as the anti-bacterial agent is integral within the paint.
In a laboratory environment it makes this one less source of contamination, contributing to essential
clean working practices. A benefit of such a paint finish can lead to a reduction in cleaning schedules
because surfaces are more protected and improves protection between cleaning. Unlike detergents
“Anti-bacterial paint finish” does not offer an instantaneous action, but is intended for long-term
general protection against bacterial growth.
Moisture on the painted surface is necessary for the bacterium to absorb the agent and be affected
by it. The coating is therefore less active in very dry conditions, but dependent upon relative humid-
ity, moisture in the atmosphere maintains activity. Areas where moisture is trapped are also areas
that normally are difficult to clean and where bacteria proliferate but these areas are most active for
the anti-bacterial coating improving the defence against bacterial growth.
Cleaning the Stainless Steel Tank
The stainless steel crevice free tank with smooth corners should provide years of valuable service and is
resistant to chloride containing solutions it is however important to avoid high concentrations of halo-
gens - especially chloride. With such a high quality and resistant tank it may show symptoms of these
halogens as rust, which are deposits from external sources in the water supply.
We recommend always empty the bath of liquid after use and wipe out the internal faces of the tank with
a non-abrasive cloth and allow to dry. Any deposits can be removed with nitric acid (10%) on a cloth.
WEAR PROTECTIVE EQUIPMENT!
It is also recommended to use an accessory lid to prevent contaminates landing in bath liquids.

The Clifton Range - 3 Year Warranty 9High Quality Products at Affordable Prices
Descaling the Stainless Steel Tank
Descale the stainless steel tank regularly to maintain it in as new condition ensuring the corrosion
resistance and normal operating conditions are maintained throughout its working life. Descale by add-
ing 1 litre of vinegar to water and gently heating to 50°C for an hour, empty and brush the lime away.
Rinse thoroughly afterwards.
Decontamination of Equipment
Clifton laboratory equipment can be decontaminated after spillage or contact with potentially HIV and
Hepatitis infected blood samples during analysis using following recommended rapid disinfectants.
Virucidal Disinfectant
We recommend Virkon tablets for the safe and rapid disinfection of equipment in a wide variety of
situations available from your distributor or contact Day-Impex Ltd. for more details. Telephone: 44+(0)1787
223232 or http://www.day-impex.co.uk
The ultimate high level surface disinfectant, dissolve VIRKON in water, providing a
safe working solution with a faint lemon odor. It has proven efficacy against bacte-
ria (including mycobacteria), viruses, spores and fungi in a variety of independent
tests using different protocols. Presents no serious long term health risks to staff –
obviating the need for costly ventilation equipment and health monitoring. Also
provides high level disinfection of laboratory equipment and instruments where
autoclaving is neither practical nor necessary. For more detailed information relat-
ing to how Virkon should be used with access to test reports www.relyon.dupont.com
Is Virkon solution corrosive? Virkon solution requires only 10 minutes contact
time to be effective so long-term exposure is not necessary and therefore will not corrode most
materials. Care should be taken with Stainless steel water bath tanks, these surfaces should not be
affected however, it is important that generally you do not leave Virkon solution in contactwith
metal surfaces “FOR LONGER THAN IS NECESSARY”.
Virkon is Registered in accordance with the requirements of the Medical Devices Directive, (93/42/EEC)

Disinfectant/Sterilant
We recommend PeraSafe a powder product for the safe and rapid chemical sterilant of equipment in a
wide variety of situations available from your distributor or contact Day-Impex Ltd for more details.
Telephone: 44+(0)1787 223232 or http://www.day-impex.co.uk
PeraSafe has a proven safety profile for end-users with none of the undesirable properties of skin
sensitisation, toxic fumes or unpleasant odours that are associated with aldehyde solutions.
Leading UK and USA microbologists have proven PeraSafe to be active
against viruses, mycobacteria and fungi. It is microbiologically superior to
glutaraldehyde, destroying sporing bacteria in one minute. It has also
