Pipette tips

Filter tips have a barrier that stops aerosols and liquid from reaching the pipette cone. Use them for PCR, qPCR, work with infectious or radioactive material, and volatile samples, where carry-over would spoil the result or contaminate the pipette. For routine buffers and reagents, standard tips are enough. A standard example is the Sapphire pipette tip, 1000 µl, non-sterile, 1000 pieces per bag. Filter tips are grouped in filter tips; for volumes, ask sales@luminixhealth.com.

Choose sterile tips for cell culture, microbiology and molecular work where any contamination counts, for example the Sapphire pipette tip, 1000 µl, sterile, 96 pieces per rack, or the 10 µl XL tip, sterile, 96 pieces per rack. Non-sterile tips are fine for chemistry and routine buffers and are cheaper to stock in bags, such as the 200 µl tip, 1000 pieces per bag. Racks also make it easier to load tips without touching them. See all pipette tips.

Low-retention tips have a surface that holds back less liquid on the inside wall. They help with viscous or detergent-containing samples, such as protein solutions, enzymes, master mixes and samples with surfactants, where a normal tip leaves a film and you lose volume. For water and simple buffers a standard tip is enough. Examples are the Sapphire Low Retention tip, 300 µl, sterile, 96 pieces per refill, and the 10 µl low-retention tip, sterile, 96 pieces per refill. Questions: sales@luminixhealth.com.

Not always. "Universal" means the tip is designed to fit many common pipette cones, but cone shapes differ by brand and model. A tip that sits too loosely leaks, and one that sits too tightly is hard to eject and can shift the volume. Check the fit on your own pipettes, ideally with a short gravimetric test, before you order large volumes. Special shapes such as the gel-load tip, 200 µl, 1000 pieces per bag need a check too.

Start from the volume range of your pipette, not from a single setting. The nominal volume of the tip must at least cover the highest volume of that range: a 20–200 µl pipette takes 200 µl tips, a 100–1000 µl pipette takes 1000 µl tips. The colour of tips or racks often matches the colour code on the pipette, but treat it as an aid, not as a guarantee of fit. Pipettes for large volumes use 5 ml or 10 ml tips, such as our pipette tips 5 ml, bulk bag and pipette tips 10 ml, bulk bag.

Racked tips sit in a box ready to use, which is the most convenient option and keeps sterile tips sterile until you open the box. A refill pack tops up a rack you already have, so you use less packaging and produce less waste. Bulk bags are the leanest option per piece for non-sterile work; you place the tips in a rack yourself and, where the product page allows it, autoclave them. Compare pipette tips 10 µl, racked, pipette tips 10 µl, refill pack and pipette tips 200 µl, bulk bag.

Long or extended tips reach the bottom of deep tubes, bottles and narrow vessels without the pipette touching the rim, which also helps with small volumes in narrow tubes, as with our long graduated tips 0.1–10 µl, sterile. Gel-loading tips have a fine, thin end to place samples precisely in gel wells, for example our gel-loading tips 200 µl, sterile, racked. Flat tips are another option for loading gels; see our flat tips 1–200 µl, racked.

A pipette tip has to seal on the pipette it was designed for. Volume range, filter or no filter, sterile or not, and low-retention are the choices. A tip that merely looks the right size leaks or falls off. Racked tips and bulk tips are the same tip in different packaging.

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.
