Frequently Asked Questions
What is the difference between the filtered and non-filtered racked tips?
SKU 151145RF includes a hydrophobic barrier filter to guard against aerosol and sample carryover, protecting both the pipette and the sample. The standard racked tips (151145R-96) are unfiltered for routine, non-critical dispensing.
Are these tips compatible with my micropipettes?
Yes. They are universal-fit and designed to seal on most major brands of single- and multichannel micropipettes covering the 0.1–20 µL range. We recommend verifying seal and calibration on first use.
Which format should I choose for sterile applications?
Select SKU 151145RS-96, which ships sterile in racks of 96 (10 racks/box). The other three formats are non-sterile and intended for general laboratory use.
What does the 45 mm extended length offer?
The extended tip reaches into deep-well plates, narrow tubes, and tall vessels without contaminating the pipette barrel, improving access for low-volume transfers in confined sample formats.
