![]() ![]() If t he area under the shaking table has a hygienic design, it will have a smooth base and is deep enough to hold spills from large flasks i.e. If necessary, disinfect with a standard disinfectant e.g. W ipe the trays and their mounted parts regularly (rails, clips, adhesive matting, etc.) with a soft cloth and a mild household cleaner. M ake sure no residues are left behind by rinsing with clean water. Only clean the glass door inside and outside with a soft cleaning cloth and mild detergent solution (diluted with de-ionised water). There is a risk of damage to the surface s due to use of abrasive cleaners such as scouring pads and similar utensils. Use a damp cloth and mild detergent to clean the touchscreen panel of the controller and the plexiglass cover protecting the lighting unit – do not apply liquid directly to the surfaces or use aggressive chemicals. Then clean with disinfectants e.g. quats, if necessary.ĭepending on your laboratory guidelines c leaning of the outside surface should be part of a general laboratory routine (SOP). If a flask has broken or culture medium has escaped, clean the chamber immediately with a neutral household cleaner as a first step. ![]() Ĭ leaning of hard surfaces inside and outside the shaker If possible, the humidification sensor should be removed or covered. As this can be used to decontaminate an entire laboratory or cleanroom areas, care should be taken to prevent access to the incubator chamber if a humidification option has been fitte d. Hydrogen peroxide : This can permanently damage humidification sensors.Use of ultra-violet radi ation to decontaminate the interior (some manufacturer provide as option for their incubation shakers).It will damage everything from interior sheet metal to solenoid valves. As a rule, do not use bleach in any device that contains metal components. ![]() O xidative disinfectants such as bleaches : I f these spla s h onto metal parts, especially bearings, they can cause corrosion.A bactericide, viricide and fungicide (Candida), effective within 5 minutes.Ī good example of a combined cleaning agent and disinfectant for incubator shakers is Fermacidal D2 from IC Products SA.Has good materials compatibility with rubber, plastic, and metal without causing oxidation.U sed for medical and general applications.A quaternary ammonium compound with the option of additives such as corrosion inhibitors.When choosing a product, the following characteristics should be considered : There are many commercial brands available which are chea p and effective hard surface cleaners for laboratory use. H owever, some residue is desirable to maximise the antimicrobial effects. They can potentially cause staining and leave a residue. They do not corrode metal or damage plastics, unlike oxidative disinfectants and cleaners such as peroxide or bleach. Quats work as surfactants (more like a wetting agent). Apply directly to the surface, allow a short time for the quats to take effect, then wipe off.Use soft water, distilled or RO (reverse osmosis) water since h ard water can make quats less microbicidal.Quats can be very effective if used properly: They are not good against some gram-negative bacteria and of little value against fungal spores and non-enveloped viruses. The antimicrobial activity depend s on the quats ’ ability to disrupt cell walls. Many g eneric ‘ quaternary ammonium compound s ’ (quats) have antimicrobial properties and are widely used as disinfectants. It can be applied with a soft, lint-free cloth such as microfibre, although u nwanted residue may be created and an additional rinse may be required. Sterili s ation – total removal of any contamination so no viable microbes (or spores) remainĪ ‘ mi l d cleaning agent ’ such as soap or household detergent will clean greasy surfaces but may have little antimicrobial activity.Disinfection – microbes on surfaced killed, inactivated and made harmless.Saniti s ation – surfaces clean ed and microbial load reduced.Disinfection should deal with most simple cases of contamination and sterilisation is reserved for serious problems not solved by the two lesser categories, or to address the requirement for certification of decontamination. Sanitisation is the most common solution for a routine clean.
