Questions about Volumetric pipettes

Class AS or class B: which accuracy do I need?

Class AS pipettes have the tightest tolerance and a fast delivery time, so they suit analysis, standard preparation and work under a quality system, such as the volumetric pipette with 2 marks, class AS, 100 ml. Class B pipettes have a wider tolerance and suit routine work, teaching and preparations where a small deviation does not affect the result, like the volumetric pipette, class B, 50 ml. The tolerance for each volume is on the product page. Use flasks of the same class from volumetric flasks. Questions? Ask sales@luminixhealth.com.

When do I need a conformity or batch certificate?

You need one when your quality system or an audit requires proof that your volumetric glassware meets its stated class. A conformity certificate confirms that the pipette type meets the requirements of its class; a batch certificate documents measured values for the production batch; the product title states which one is included, as with the volumetric pipette, class AS, with batch certificate. For individual certificates per pipette, see volumetric accessories and certificates. For teaching and routine work without audit requirements, a certificate is usually not needed. Unsure? Ask sales@luminixhealth.com.

Volumetric pipette with one or two marks, or a blow-out pipette?

A pipette with one mark is filled to the mark and then allowed to drain freely; the small remainder in the tip stays there, because the calibration accounts for it. A pipette with two marks delivers the volume between the upper and lower mark, so you stop at the lower mark, as with the volumetric pipette with 2 marks, class AS, 100 ml. A blow-out pipette is calibrated to deliver everything, including the last drop, which you blow or push out, like the blow-out volumetric pipette, 100 ml, class AS. For variable volumes, see graduated pipettes. Questions? Ask sales@luminixhealth.com.

Which pipetting aid should I use with a volumetric pipette?

Always use a pipetting aid, never your mouth. A rubber pipette bulb is simple and fits most volumetric pipettes; a motorised pipette controller is faster and more comfortable when you pipette many samples or larger volumes. Choose an aid that holds the pipette firmly and lets you release liquid in a controlled way, so you can set the meniscus exactly on the mark. Check the pipette diameter range on the product page of the aid. Options are in pipette controllers and fillers. For the pipettes themselves, see the volumetric pipette, class B, 50 ml. Questions? Ask sales@luminixhealth.com.

Why Volumetric pipettes?

A volumetric pipette has a single mark and a bulb, and it delivers one volume with a tighter tolerance than a graduated pipette. It is for preparing standards. It is not for reagents that attack glass, and it is not a blow-out pipette unless it is marked as one.

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.
