Questions about Pasteur pipettes

Glass or plastic Pasteur pipette: which should I choose?

Glass Pasteur pipettes resist organic solvents and hot liquids, and they are used with a separate rubber bulb, such as the Pasteur pipette, soda-lime glass, about 225 mm. Plastic pipettes made of LDPE are unbreakable, have the bulb built in and are disposed of after use, as with the Pasteur pipettes, PE, 150 mm. Choose glass for solvents and chemistry, plastic for aqueous solutions, biology and teaching, where breakage is a risk. Questions? Ask sales@luminixhealth.com.

Graduated or ungraduated Pasteur pipette, and which volume?

A graduated Pasteur pipette gives a rough indication of the volume you draw up, which helps when you add a few millilitres without measuring exactly, as with the Pasteur pipette, LDPE, graduated. It is not a measuring instrument: for accurate volumes, use a pipette from graduated pipettes or a piston pipette. Ungraduated pipettes suit transferring and adding drops. Volume and length are in each product title; choose a length that reaches the bottom of your tube or flask. Questions? Ask sales@luminixhealth.com.

Sterile or non-sterile, loose or packed?

For cell culture and microbiology, choose sterile pipettes, ideally packed individually, so each one stays sterile until you open it at the bench; the product title states sterility and packing. Products for this work are grouped in cell culture. For general chemistry and routine transfers, non-sterile pipettes in bulk packs are practical and economical, such as the disposable transfer pipettes. Store opened bulk packs closed to keep out dust. Unsure which pack suits your workflow? Ask sales@luminixhealth.com.

Which rubber bulb fits my glass Pasteur pipette?

Choose the bulb by volume and by the neck diameter of the pipette. A 2 ml bulb, such as the rubber bulb for glass Pasteur pipettes, 2 ml, fits standard glass Pasteur pipettes and draws up enough liquid for most transfers. The bulb must close tightly around the pipette top, or it will draw air instead of liquid. If you work with latex allergies, check whether the product page states latex-free. For larger volumes or repeated work, a pipette filler from pipette controllers and fillers is more comfortable. Questions? Ask sales@luminixhealth.com.

Why Pasteur pipettes?

A Pasteur pipette is an uncalibrated glass or plastic transfer pipette. It moves a drop. It does not measure. Glass ones are pulled to a tip. Plastic ones are a single piece. Neither belongs in a result that needs a stated volume.

A pipette moves a measured volume. A volumetric pipette delivers one line. A graduated pipette delivers along a scale. A Pasteur pipette is an uncalibrated transfer. A piston pipette uses a tip, and the tip has to seal on that pipette. A filter tip adds a barrier so aerosol from the sample does not reach the piston. Serological pipettes are the long graduated tubes used with a controller. The volume and the fit are the specification. Piston pipettes are treated under ISO laboratory apparatus. In-vitro work also meets ISO in vitro diagnostic systems.
