Lab Supplies for Cleaning

Cleaning up at the best of times is a tough job. In a laboratory it is more than that. There are all kinds of complications involved with cleaning up a lab after the work and experiments are done.

The first reason is that ordinary detergents cannot always be used. You have to know what substances and chemicals were used in the work before you choose what to clean the surfaces and containers with. You need to know whether there will be a reaction between the chemicals used and your cleaning substances. Then you need to use cleaners that will be effective. Some messes can be impossible to clean unless you use exactly the right chemical.

The second reason is that the standard of cleanliness you would expect in a really clean kitchen is not enough for a laboratory. Cleanliness in a laboratory generally means ‘sterile'. Even if no harmful substances were used in the work, any residue at all, even detergent residue is going to have an impact on the next test or experiment.

If you check out Cole-Parmer's lab supplies, you will see that they have made provision for all sorts of cleaning situations. To help you save labour and time, they have glassware scrubbers in large free standing models as well as small table top types.

They differ greatly from ordinary dishwashers in more than just the layout of the racks. Purified water rinses, and filtered forced air drying assists decontamination and reduces adherence of contaminants. Even narrow necked glassware is thoroughly cleaned by spindles that reach right inside the flasks. Pipettes, almost impossible to clean even by hand, are catered for with stands for direct injection cleaning.

Cole-Parmer offer models with two water pumps, one for washing and one for draining, to reduce cross-contamination. The factory preset programs give the options of a range of washes and temperatures, as well as a delayed start option. Separate inserts can be supplied for your labs' own needs.

Cole-Parmer Lab Supplies have both washing powders and washing liquid suitable for laboratory cleaning purposes. These come with the dispenser you prefer. They supply low foam cleaners, micro cleaners, citric acid cleaners, enzyme cleaners and surface cleaners that remove the residue of other acidic or alkaline cleaners.

For washing with hands, you can get a foam covered glassware cleaning brushes as well as all sizes of bristle brushes right down to micro tube brushes. These are also available in long, contoured or flexible shapes and sizes for cleaning awkward apparatus, like glass tubing.

A whole range of brooms and brushes are available for cleaning out the laboratory and work surfaces as well.

When the cleaning is done, the sterilization begins. Here are a few methods used for sterilization:

* You can get combination filter/ultraviolet sterilizers.

* Liquid disinfectants, such as glutaraldehyde are not frequently used as they disinfect rather than sterilize.

* Heated chemical vapour is used to sterilize metal instruments.

* Dry heat sterilizers are often preferred for metal instruments as they do not cause rust and corrosion.

* Steam autoclaves.

Where can I find a variable speed vibratory machine used in small laboratory applications?

I'm looking to find a variable speed vibration machine. Something compact would be best. Ideally I'd like something around the 50-300 Hz range which can be controlled by an external device. Trying to find a vibrator on the internet that isn't for sex is proving to be hard (that's what she said). Any help would be appreciated.

I've tried McMaster-Carr and Cole Parmer.

Vibrators are frequently used in manufacturing and packaging. Maybe you can find what you need by looking at an equipment catalog rather than a scientific catalog.
The Thomas Register is great for finding obscure things:
