Laboratory cleaning and disinfection: how can biocontamination of surfaces and equipment be controlled?

In the lab, effective control of biocontamination relies on an inseparable duo: cleaning (removal of soils) followed by disinfection (reduction of bioburden). From the bench to the incubator, from the water bath to the glasswasher, and through the air (airborne surface disinfection/fogging, filtration), each area requires dedicated chemistry and a validated protocol compliant with EN standards and the EU BPR. Wipes, detergent-disinfectants and cleaning accessories: choose effective, traceable and material-compatible solutions for reproducible results.

What are the different types of cleaning and disinfection solutions?

• Air decontamination: purification via HEPA/ULPA filtration, UV-C or mobile units to reduce airborne particles and micro-organisms. Complements good practice (controlled flows, air renewal).
• ASD (airborne surface disinfection): dry misting (e.g. H?O?) to treat room volumes and hard-to-reach surfaces. Look for NF T72-281 compliance, homogeneous distribution and validated contact time.
• Wipers & wipes: for floors (high absorbency, low lint) and high surfaces/hands.
• Instrument/surface cleaners & disinfectants: alcohols, quaternary ammonium compounds, peroxides, peracetic acid. Check each product’s efficacy spectrum to match your needs (yeasticidal, fungicidal, virucidal up to sporicidal), material compatibility, and the right pack size/format for the areas to be treated.
• Water bath products: anti-algae/antifoam additives, corrosion inhibitors for stainless-steel tanks; limit biofilm and odours.
• Incubator products: non-corrosive cleaners, compatible with probes and anodised surfaces; sporicidals for microbiological reset cycles.
• Washer & sink products: alkaline/neutralising/acid detergents, rinse aids, descalers. The right chemistry protects glassware, maintains wash performance and reduces rewash cycles.

Type	Principle	Applications
Alcohol (IPA/ethanol)	Protein denaturation	Smooth surfaces between steps; fast evaporation, not sporicidal
Hydrogen peroxide	Free-radical oxidation	ASD/NF, furniture and equipment surfaces; low residue
Quaternary ammonium compounds	Membrane disruption	Non-critical surfaces; good residual effect, watch residues
Peracetic acid	Powerful oxidant	Instruments, washers; broad spectrum including spores

Which application areas are these solutions used in?

• Pharma/biotech : classified cleanroom areas, biomanufacturing, microbiology QC.
• Life sciences/academia : benches, laminar flow cabinets, CO? incubators.
• Food & beverage : QC laboratories, sample-prep rooms.
• Cosmetics : ISO 5–8 cleanrooms.
• Chemistry & environment : glassware washers, wash-up area, water baths; detergent chemistries matched to residue type and water hardness.
• Animal facilities : containment areas, enhanced procedures and whole-room bio-decontamination (fogging/VHP) for microbiological reset.
• Water & utilities : terminal (point-of-use) filters and additives to limit biofilms in pipework and sensitive equipment.

Frequently asked questions on laboratory cleaning and disinfection

What’s the difference between cleaning and disinfection?
Cleaning removes soils and biofilms. Disinfection reduces the bioburden according to a standardised spectrum. The latter is ineffective without the former.

Which standards should you check for a surface disinfectant?
Look for EN 1276 (bactericidal), EN 13697 (surfaces), EN 14476 (virucidal), EN 13704 (sporicidal) and, for wipes, EN 16615. Request evidence of compliance and validated contact times.

What is DSVA used for and what do NF T72-281 or the new EN 17272 guarantee?
DSVA (airborne surface disinfection) treats surfaces, even the hardest-to-reach ones. The NF T72-281 standard (and EN 17272) certifies efficacy against target microorganisms under representative conditions, with a validated protocol and exposure time.

Pre-impregnated wipes or spray + wiping cloths?
Validated wipes (EN 16615) control the biocide dose and the area covered per wipe, help reduce MSD risks, and ensure reproducibility.

How can you avoid equipment corrosion?
Select resistant, compatible materials (316L stainless steel, PMMA, EPDM seals), and rinse when required.

When should a terminal water filter be replaced?
Follow the manufacturer’s stated service life (months or treated volume), monitor pressure drop and any sign of clogging/biofilm. Log replacements for audit traceability.
