Manual versus machine preparationMany laboratories choose to usewasher disinfectors for processing theirlaboratory equipment such as beakers,pipettes, measuring flasks, conical andErlenmeyer fasks, Petri dishes, testtubes etc.

One reason is to avoid the dangerposed by manually handling potentiallydangerous equipment. Broken glassfrom manual cleaning, for instance, cancause dangerous injuries. Infectiousand toxic contaminants pose a healthhazard. Cleaning agents used oftencontain substances that are highly irri-tant.

Because washer disinfectors operateas a closed system with programmesthat run fully automatically, the poten-tial danger to laboratory personnel canbe kept to a minimum This in turnmeans that machine preparation pro-vides personnel with maximum protec-tion.

Machine preparation also ensures thatpreparation can be standardised, vali-dated and documented.

Laboratories use a wide variety ofequipment made from glass, ceramicware and plastic for testing and ana-lysis, for isolating or cleaning sub-stances before, during and after pro-cedures, taking samples etc. Followingon from this cleaning and drying areessential. The cleaning process mustensure that equipment, when usedagain, is not affected by its previoususe.

The scenario will vary a lot from onelaboratory to the next. To establishwhich machines and accessories,cleaning agents, water quality andcleaning programmes are the bestones for your needs the followingaspects need to be considered:

1) ApplicationThe application needs to be divided upinto general areas first (organic, inor-ganic or physical chemistry, biology,microbiology, hospital, pharmaceutical,food industry, or cosmetic industrylaboratory etc.) and then into areas ofapplication or working practice (prepa-ration work, analysis, test samplingetc.). The type of application will alsobe an important deciding factor in thetype of machine and accessories aswell as the cleaning process and selec-tion of cleaning agents required.

2) Laboratory equipmentLaboratory equipment needs to bebroken down into its various compo-nents (beakers, conical flasks, mea-suring flasks and cylinders, pipettes,Petri dishes, test tubes, phials, centri-fugal test tubes etc.), their size or volu-me (1 ml, 500 ml, 1,000 ml) and thenumber of items requiring processing.This information will enable us to prov-ide a detailed quotation of the rightsystem for your requirements.

3) ContaminationKnowledge of physical and chemicalattributes of the types of contaminationthe machine will need to deal with areof particular importance in choosingthe cleaning process and type ofcleaning agent to use.

Physical and chemical properties of acontaminant include, for instance, itssolubility in water under acid, pH-neu-tral or alkaline conditions, its chemicalreaction to hydrolysis or oxidation, itsmelting or softening point, its ability toemulsify, its suspension or dispersingproperties.

4) DisinfectionFor certain applications laboratoryequipment has to be disinfected. Onthe one hand this protects laboratorypersonnel who come into contact withinfectious contaminants at work. Andon the other disinfection prevents bac-terial cross contamination of test sam-ples and instruments in medical labora-tories, hygiene institutes, pharmaceuti-cal laboratories, food and cosmetic in-dustry laboratories.

5) Analytical methodsMethods of analysis used can beinfluenced by particular contaminantsin laboratory glassware. Knowledge ofthese factors can help in selecting thecorrect cleaning agent.

5) Analytical methodsMethods of analysis used can beinfluenced by particular contaminantsin laboratory glassware. Knowledge ofthese factors can help in selecting thecorrect cleaning agent.

6) Analytically cleanEach laboratory will have its own defi-nition of “analytically clean” dependingon the specification, nature and repeat-ability etc. of test methods used. Thewasher disinfector including all its ac-cessories and the cleaning programmeused must be able to achieve cleaningresults that meet the standards requiredby the definition.

SolutionBecause requirements vary from onelaboratory to the next standard solu-tions are often not feasible. More oftenthan not customers require solutionswhich are specific to their particularneeds. By working together with labo-ratory personnel, Miele are able to prov-ide tailor made solutions for individualrequirements.

Miele: The professionals in processing laboratory glassware

The Miele systems cover all ofthe following aspects:

● Cleaning, disinfection and drying

● Water preparation

● Detergent recommendations

● Cleaning programmes can beprogrammed and evaluated

Systematic preparation of laboratory glassware

6

Cleaning and dryingThe Miele system consists of thefollowing components:● Washer disinfector● Baskets and inserts for laboratory

equipment

Miele’s G 7883– G 7736 CD washerdisinfectors are single cabinet systemsin which the whole process takes place(wash, rinse and disinfection if appli-cable, followed by drying) in a closedsystem. The cleaning process is car-ried out with injectors using water ba-sed agents. Programmable Profitronicand MCU controls enable programmesto incorporate specific process para-meters (temperature, time, amount ofcleaning agents etc.) for the cleaningtask in hand. With the Multitronic Novoplus controls specific process parame-ters can also be changed in standardcleaning programmes. The controls areable to monitor and maintain the rele-vant process parameters ensuring con-sistent standards of cleanliness. Otherfeatures and options, such as heatingfor the process water, dispensers foracidic, ph-neutral or alkaline cleaningagents, high performance circulationpumps, hot air drying units and auto-matic mobile unit recognition enablecleaning processes to be carried outfully automatically.

Miele offer a wide range of mobile unitsas well as baskets and inserts forlaboratory glassware processing.There are injector jets for pipettes andmeasuring flasks, conical and Erlen-meyer flasks. Injector jets ensurethorough internal cleaning, rinsing anddrying of laboratory glassware. Rotat-ing spray arms ensure thorough exter-nal cleaning and rinsing.

There are special inserts for holdingbeakers, Petri dishes, wide neckedbottles and Erlenmeyer flasks and testtubes securely. These can be placed inthe lower or upper basket. The sprayarms in the machine and in the upperbasket ensure excellent internal andexternal cleaning and rinsing results.

Water preparationVery often different quality water is re-quired for different stages of a pro-gramme, e.g. for the wash and therinse.Usually the beginning of a wash pro-gramme would use softened water(pre-wash, main wash and first rinses).Using softened water prevents lime-scale building up in the machine aswell as unwanted side effects duringthe cleaning process.

Fully demineralised purified water isthen used in the final rinsing stages.This water quality ensures the verybest surface cleanliness of laboratoryglassware. However, to ensure thislevel of cleanliness any contaminationmust first be removed.

Cleaning agentCleaning agents can generally be splitinto 3 groups.● alkaline products● pH neutral products● acidic products

Alkaline cleaning agents are complexmixtures and can contain substancessuch as potassium or sodium hydroxi-de, silicates, cabonates, polycarbona-tes, complex compounds, tensides,enzymes, oxidation agents etc. Thecleaning agent must be selected ac-cording to application and type ofcontamination on the equipment. Forinstance cleaning agents without ten-sides, but preferably with oxidationagents should be used for equipmentused for plant and cell cultures. Ifsamples are being analysed for phos-phorous or phosphates in a laboratory,then the detergent should be phospha-te or phosphonate free.

pH-neutral products generally containtensides, emulsifiers or enzymes. Theyare occasionally used together withalkaline cleaning agents.

Acidic products are based on citric orphosphoric acid. They are often usedfor neutralisation of laboratory equip-ment after cleaning with an alkalineagent. Sometimes it is necessary touse a strong acidic cleaning agent, e.g.to remove limescale deposits fromflasks used for water testing.

Cleaning programmeThe wash programme consists ofseparate stages of a process carriedout in the correct order using theappropriate cleaning agents. To createa suitable programme it is important toknow the physical and chemical pro-perties of the type of contaminationbeing handled.Many contaminants are water solubleor can be dissolved using alkalines(e.g. organic acids) or acids (e.g. amineand some metal oxides).Chemical changes can convert someinsoluble residues into soluble matter(e.g. alkaline hydrolysis of animal fatsand oils into fatty acids and glycerine).Other contaminants are virtually chemi-cally inert and can only be brokendown or emulsified using high tempe-ratures and tensides (e.g. paraffin wax).In certain circumstances dispensingthe incorrect amount of cleaning agent,or running a programme with the pro-cess parameters set in the wrong ordercan lead to unsatisfactory results (e.g.running a hot pre-rinse on items conta-minated blood will cause the blood tocoagulate).

Process assuranceThe aim of all laboratories is to carryout standardised processes which canbe validated. In order to validate pro-cesses and working procedures thesemust be reproducible and be suitablefor being documented. This requires ahigh degree of process assurance.The controls used on Miele washerdisinfectors can monitor validated pro-cedures and working processes, e.g.they can:● control and monitor temperature and

time● control the pressure of the recircula-

tion pump● control and monitor the amount of

water used● monitor level in the supply canisters

and control the amount of liquidagents dispensed

Laboratory glasswareMost laboratory equipment is madefrom borosilicate glass. Unlike othertypes of glass (except: quartz glass)borosilcate glass has very good physi-cal properties and is highly resistant tochemicals. Fluxing acids and strongsuds will still etch into the surface ofglassware if the concentration, tem-perature and effective periods areincreased. Because of this alkaline cleaningagents are generally used. If at all pos-sible longer holding periods should beavoided at temperatures significantlyhigher than 70°C, and mildly alkalinecleaning agents should be used to re-duce glassware corrosion to a mini-mum. The deterioration rate of glasswaremust be taken into account accordingto its application. For instance etchingon a simple beaker is not a major pro-blem. However, could lead to inaccura-te results with volumatic equipmentsuch as pipettes.

ConclusionIt is essential for laboratories to be pro-vided with customised solutions fortheir specific needs.

Setting the standard

14

Setting the standardThorough cleaning is an essential pre-requisite for preparing analytically cleanlaboratory glassware for reproducableresults. The cleaning and disinfectingprocesses must also be validated inaccordance with Health and Safetyregulations. Programme data andsequences must be documented.

Miele’s latest generation of washer disinfectors comply with the require-ments of EN ISO 15883.

The new generationMiele, as a leading and innovativemanufacturer, has set new standardsfor washer disinfectors with the latestG 78 generation of machines. And indoing so have also been thinking aboutyour pocket: All new machines can beequipped with your existing seriesG 77 machine baskets and inserts – soyou won’t need to replace everything –typically Miele.

The new G 7883, G 7883 CD andG 7835 CD washer disinfectors are asignificant development in the historyof cleaning and disinfecting by machi-

ne. They offer the very best in perfor-mance and reliability – both for thesmall laboratory as well as for labora-tory glassware processing in industrialand research laboratories. The singlecompartment system offered by Mielewasher disinfectors, in which eachmachine cleans, disinfects and dries,has proved itself as particularly flexibleand economical. The automatic mobileunit recognition on the G 7835 CD,further ensures that instruments arecleaned in the correct programme.

Miele’s new washer disinfectorshave an excellent safety record justas you would expect from Miele.

Serial interface for PC or printerconnection for documenting processparameters.

Separate sensors control and monitorthe process to ensure that the machineis able to maintain cleaning, disinfec-ting and final rinse temperature para-meters with even greater precision.

Validation and revalidation is possiblethanks to the controllability of the tem-perature in the wash cabinet and onthe items being processed via themany temperature sensors.

The door is securely locked for thewhole programme duration.It can only be opened at the end of theprogramme if all programme parame-ters have been successfully achieved.

SaferMore economicalBetter results

15

Miele’s new washer disinfectorsare economical to run just as youwould expect from Miele.

The steam condenser with heat ex-changer ensures significantly reducedwater consumption on machines with-out a drying unit.

Thanks to the new Profi Monoblocwater softener reactivation during acleaning programme has led to a re-duction in salt consumption of about50% (in hardness range 5°–15° dH/89-267ppm). A separate reactivationprogramme is not necessary.

If you update your machine to a newermodel you can still use your existingbaskets.

Service friendly and easy to recycleconstruction.

Miele’s new washer disinfectorsprovide excellent cleaning per-formance just as you would expectfrom Miele.

The spray arms have been designed todeliver maximum cleaning power to thesurfaces being washed at the sametime as being economical with theamount water they use.

A high pressure is used for injectormobile units to ensure thorough internalcleaning e.g. of narrow necked glass-ware.

An additional spray arm ensures exter-nal surfaces are also thoroughly clean-ed, especially when injector units arebeing used.

Improved wash results have beenachieved by arranging the jets carefullyand regulating the rotation of the sprayarms.

Greater programming flexibility forcleaning and disinfecting programmeshas been achieved with the newelectronic controls.
