500–1000 µL Two-Step Tiered Pipet Tips — Oxford®/Abbott® Replacement, PP, Green, 1000/Bag
These 500–1000 µL polypropylene pipet tips feature a two-step tiered shaft design engineered as a direct replacement for Oxford®, Abbott®, Pfizer®, and Quickpette® pipettors. Supplied non-sterile in bulk 1000/Bag packaging, they are well suited to high-throughput clinical, research, and pharmaceutical workflows where reliable tip retention and accurate large-volume delivery are essential. The green color coding provides instant visual identification consistent with the large-volume pipet tip convention, reducing tip selection errors at the bench.

- Pharmaceutical formulation and quality-control pipetting workflows
- General research pipetting where bulk, non-sterile supply reduces per-tip cost
Compatibility
The two-step tiered shaft profile of these tips is specifically designed to match the tip-channel geometry of Oxford®, Abbott®, Pfizer®, and Quickpette® pipettors, providing the secure tip attachment, airtight seal, and accurate volume delivery that instrument-matched fitting enables. Laboratories currently purchasing OEM tips for any of these pipettor brands can evaluate part number 230-1093-G3K as a cost-effective replacement. As pipettor manufacturers sometimes offer multiple models within a volume class, it is good practice to verify cone dimensions against your specific model before transitioning from OEM supply.

Frequently Asked Questions
Are these tips sterile?
No — they are supplied non-sterile in 1000/Bag bulk packaging, which is appropriate for the majority of general bench, clinical chemistry, and reagent-handling workflows that do not require a certified sterile tip.
Which pipettor brands do these tips fit?
The two-step tiered design is engineered to replace OEM tips for Oxford®, Abbott®, Pfizer®, and Quickpette® pipettors in the 500–1000 µL class. Always confirm that your specific pipettor model uses this tip size before switching from OEM supply.
Can polypropylene tips be used with organic solvents?
Polypropylene offers excellent resistance to aqueous buffers, dilute acids and bases, and short-term contact with common alcohols and acetonitrile. Prolonged exposure to aromatic or chlorinated solvents such as toluene or chloroform is not recommended, as these can degrade PP over time.
