Collection: Pipette Tips & Serological Pipettes

Whenever aerosols could contaminate your pipette or the next sample — PCR and qPCR setup, nucleic-acid work, infectious materials, or volatile liquids. Sapphire filter tips use a hydrophobic polyethylene barrier that blocks aerosols; the filter is not self-sealing, so if liquid accidentally reaches it, the whole sample can still be recovered.

Low-retention tips have a hydrophobic inner surface that lets liquid sheet off instead of clinging, cutting the residual volume left in the tip. They pay off with detergent-containing buffers, precious enzymes, and small volumes where a clinging droplet is a real percentage error. Greiner offers Sapphire low-retention versions with and without filters.

Greiner publishes a tip-fit chart matching Sapphire tips to common pipette models from the major brands. Volumes span 10 µl to 1250 µl, including XL lengths, in racked sterile and non-sterile formats — check the chart or ask us to confirm the fit for your pipettes.

CELLSTAR serological pipettes carry ascending and descending graduations so volume can be read during both aspiration and dispensing. The plug in the mouthpiece is a filter barrier that stops liquid from being drawn into the pipette controller. Sizes run 1 to 50 ml, with compact Shorties and plug-free aspiration models for special cases.

Israeli labs order Sapphire tips and CELLSTAR serological pipettes through Danyel Biotech — Greiner Bio-One's official distributor for Israel — which keeps routine liquid-handling formats in local stock and quotes quickly on standing orders.
