Brush, Cleaning

Quick Answer: The Brush, Cleaning is a general-purpose laboratory brush for scrubbing glassware, plasticware and small apparatus during washing up. A laboratory cleaning brush removes residues mechanically; it cleans but does not disinfect or sterilise, so it is used before any rinsing, disinfection or autoclaving step.

Cleaning, Disinfection and Sterilisation Are Different Steps

In a laboratory, clean means free from visible residue and films, which is what a brush and detergent achieve. Disinfection reduces living microorganisms, usually with a chemical disinfectant, and sterilisation kills all of them, typically by autoclaving or dry heat. The order matters: residue shields microbes from disinfectants and steam, so items from microbiology work are first made safe, then washed and brushed, and sterilised again if they will be reused for cultures. A cleaning brush is therefore one part of the routine, not the whole of it.

The listing names this simply as a cleaning brush and does not state its shape, size or bristle type. General-purpose brushes of this kind are commonly used on items that do not need a shaped brush: wide-mouthed bottles, jars, funnels, dishes, trays and bench apparatus. For vessels with a particular shape, the dedicated brushes in this range fit better, such as the beaker brush or the flask brush.

Specifications

Applications

• Washing reagent bottles, specimen jars and funnels at the laboratory sink.
• Scrubbing dissection trays and boards after biology practicals, before disinfection.
• Cleaning the outside of apparatus and bench fittings.
• Removing dried media from culture vessels after they have been autoclaved and emptied.

Good Washing Practice

• Wear gloves and eye protection when washing glassware that has held chemicals.
• Keep separate brushes for general chemistry, microbiology and very dirty items to avoid carrying residues between them.
• Rinse the brush clean after use and let it dry head down.
• Replace brushes that are worn, stained or smell, since they redeposit dirt.

Frequently Asked Questions

Does brushing sterilise glassware?

No. Brushing with detergent removes residues but leaves microorganisms alive. Glassware for microbiology must be sterilised afterwards, for example by autoclaving or dry heat.

In what order should contaminated glassware be cleaned?

Items that held cultures are first decontaminated, usually by autoclaving or soaking in disinfectant. They are then emptied, washed and brushed with detergent, rinsed and, if needed for cultures again, sterilised.

Which detergent should be used with the brush?

A laboratory detergent that rinses away completely is preferred. Household detergents may leave perfumes or residues that interfere with sensitive tests, so rinse well if they are used.

Why keep separate brushes for different jobs?

A brush holds residue in its bristles. Using the same brush for oily, microbiological and analytical glassware can transfer contamination from one to another, so separate brushes are good practice.

Which shape of brush should I choose?

Match the brush to the vessel: narrow and long for tubes, burettes and cylinders, bent or fan-tipped for flasks, and wide for beakers and jars. A general brush suits open vessels without awkward shoulders.

How do I dry glassware after brushing?

Rinse with distilled water and let it drain on a rack or pegs. Oven drying suits ordinary glassware, but calibrated items such as volumetric flasks, pipettes and burettes are normally left to dry in air.
