Manual v. machine-based reprocessing

Many laboratories have deliberately chosen to wash their laboratory glassware, e.g. beakers, pipettes, volumetrics and flasks, Erlenmeyer flasks, Petri dishes and test tubes, in a machine-based process. One reason for this is to avoid the risk of exposure to hazardous substances. Broken glass from manual cleaning, for instance, can cause serious injuries. Infectious and toxic contaminants pose a health hazard. Cleaning agents often contain substances that are highly irritant. Automatic, machine-based processes are also more easily standardised, validated and documented. Because washer-disin- fectors operate as a closed system with programmes that run fully automatically, the potential risk to laboratory personnel can be kept to a minimum. This in turn means that machine preparation provides personnel with maximum protection.

Laboratories use a wide variety of equipment made from glass, ceramic ware and plastic for testing and analysis, creating reactions, for isolating or cleaning substances and for taking samples, etc. Following on from this, cleaning and drying are essential. The cleaning process must ensure that equipment, when re-used, is not affected by its previous use. Requirements vary widely from one laboratory to the next. To establish which machines and accessories, cleaning agents, water quality and cleaning programmes best suit an application, the following aspects need to be considered:

1. Applications

Applications subdivide into general areas (organic, inorganic or physical chemistry, biology, microbiology, hospital, pharmaceutical, food industry or cosmetic industry laboratories, etc.). The type of application will also be an important factor in determining the type of machine and accessories as well as the cleaning process and cleaning agents required.

2. Laboratory machines

Laboratory equipment needs to be classified according to its various components (beakers, conical flasks, measuring flasks and cylinders, pipettes, Petri dishes, test tubes, phials, centrifugal test tubes, etc.), and according to size and volume (1 ml, 500 ml, 1000 ml) and the number of items requiring processing. This information will enable us to quote the right system for your requirements.

3. Contamination

An intimate knowledge of the physical and chemical attributes of the contaminants the machine will need to deal with is of particular importance in choosing the most appropriate cleaning process and detergents.

Physical and chemical properties of a contaminant include, for instance, its solubility in water in acidic, pH-neutral and alkaline conditions, the efficacy of hydrolysis or oxidation, melting and softening points, its ability to emulsify as well as a substance’s suspension or dispersing properties.

4. Disinfection

For certain applications laboratory glassware has to be disinfected. On the one hand this protects laboratory personnel who come into contact with bacterial contamination at work. And on the other, disinfection prevents bacterial cross-con- tamination of test samples and instruments in medical laboratories, hygiene institutes and pharmaceutical laboratories in the food and cosmetics industry.

5. Analytical Methods

The results of analyses can be falsified by contaminants on laboratory glassware. Knowledge of these factors can help in selecting the correct cleaning agent.

6. Analytical purity

Each laboratory has its own definition of “analytical purity”, depending on specifications and the nature and reproducibility of test methods. The washer-disinfector, including all its accessories and the cleaning programme used, must be able to achieve cleaning results that meet the standards required by the application.

Miele’s systematic approach covers the following process stages

•Cleaning, disinfection and drying

•Baskets and inserts

•Water treatment

•Detergent recommendations

•Compilation and analysis of cleaning programmes

•Machine commissioning by Miele Service

•Qualification package: Installation Qualification (IQ) and Operation Qualification (OQ)

•Peace-of-mind package including maintenance and service contracts

Fully electronic controls, excellent process security

Programmes and functions on Miele wash- er-disinfectors G 7883 and G 7893 CD are reliably controlled and monitored by MULTITRONIC controls. The majority of routine reprocessing tasks are covered by standard washing and disinfection programmes. Process parameters, reprogrammable within the individual blocks that constitute a programme cycle, allow further customising to cater for individual needs. The serial RS 232 interface (depends on model) allows all process data to be ported to a printer or PC for documentation. The protocol contains key programme data such as running times, temperatures, dispensing and information on errors and manual intervention.

Excellent user convenience

Self-explanatory symbols on fascia panel. The machine status is indicated at any given time via control lamps. A 3-digit 7-segment indicator in the display with its own toggle switch can be used to display the remaining programme duration or the current washing/disinfection temperature. Status and control indicators monitor the process and inform of faults and the need for servicing.

•Electronic controls MULTITRONIC NOVO PLUS

•10 standard washing and disinfection programmes

•Parameters programmable in wash blocks

•2 free programme slots for customised programmes

•Rotary programme selector switch

•Programme sequence indicator and fault and service indicators

High performance, efficient use of energy

High performance, economical Miele washer-disinfectors offer a large inner cabinet with 2 wash levels (upper and lower baskets) for laboratory glassware and accessories. Direct docking of the upper basket onto the water circulation system reduces water consumption per cycle. Even the water entering the machine is carefully metered. A flowmeter monitors water intake quantities and thereby ensures precise detergent concentrations. Water and effluent costs are therefore reduced accordingly.
