Technical Narrative
The Caplugs® Evergreen 230-1093-G3K is a 500–1000 µL Two-Step Tiered PP Pipet Tip, Green, 1000/Bag, as a replacement for Oxford®/Abbott®/Pfizer®/Quickpette® pipettors. Oxford, Abbott, Pfizer, and Quickpette pipettors share compatible cone dimensions in this volume range — the two-step tiered geometry provides a single tip that fits all four brands without separate SKUs for each. Green 500–1000 µL tip matches the Oxford/Abbott/Pfizer/Quickpette OEM green tip convention for 500–1000 µL.
PP two-step tiered tip: chemical resistance to standard aqueous and biological sample types, low extractables, positive-lock two-step fit for secure seal and clean ejection. BPA-free, phthalate-free,

| RNA/DNA extraction | Column elution, precipitation volumes | 500–1000 µL for extraction protocol volumes |
| Enzyme assay setup | Substrate and enzyme dispensing | PP: compatible with standard enzyme assay reagents |
| Clinical chemistry | Serum, plasma sample prep | Two-step fit: Oxford/Abbott/Pfizer/Quickpette |
| Bulk pipetting | 1000/Bag non-sterile for routine bench use | Cost-effective replacement at high-volume lab use |
Chemical Resistance — Polypropylene (PP) Pipet Tip
Compatibility reference at typical laboratory conditions.
| Reagent / Condition | Compatibility | Notes |
|---|---|---|
| Aqueous buffers / saline | Excellent | PP compatible across standard biological buffer pH. |
| Dilute acids/bases (<10%) | Excellent | PP: broad acid/base resistance for analytical use. |
| Ethanol (<70%) | Good | Short-term compatible. |
| Methanol / acetonitrile | Limited | Brief contact acceptable; avoid prolonged immersion. |
| DMSO (<10%) | Good | Compatible at standard compound concentrations. |
| Protein solutions | Excellent | Low-retention PP bore for biological sample types. |
| Glycerol / viscous samples | Excellent | PP: inert to glycerol; wide bore on reservoir tips reduces retention. |
| Acetone / chloroform | Not Compatible | Dissolves or causes stress; do not use. |
Clinical & Research Laboratory Applications
Caplugs® Evergreen 500–1000 µL two-step tiered green PP pipet tips serve clinical and research laboratories using Oxford, Abbott, Pfizer, or Quickpette pipettors in the 500–1000 µL volume range. These four brands share compatible cone dimensions at this volume range — one Caplugs Evergreen SKU replaces OEM tips across all four brands, simplifying procurement and reducing the number of separate tip SKUs a laboratory must manage. The green color matches the standard OEM color convention for this volume range, enabling smooth transition from OEM supply without retraining laboratory staff on new color identification. At below-OEM per-tip pricing in 1000/Bag format, these tips provide meaningful per-tip savings for high-volume labs running hundreds of pipetting operations per day in this volume range.

Frequently Asked Questions
Are the pipet tips sterile?
No. Non-Sterile — 1000/Bag for general bench use.
Are these tips compatible with all four listed brands simultaneously?
The two-step tiered geometry is designed to fit Oxford, Abbott, Pfizer, Quickpette pipettors in this volume range, which share compatible cone dimensions. Verify fit on your specific pipettor model — test one bag and confirm seal, tip retention, and ejection performance before committing to bulk purchase. Slight dimensional differences between individual pipettor models within a brand may affect fit.
What does the tip color (Green) indicate?
Green is the standard OEM color convention for 500–1000 µL replacement tips in the Oxford/Abbott/Pfizer/Quickpette pipettor family for this volume range. Matching the OEM color allows operators to identify the correct tip by color without changing laboratory workflow or tip selection procedures when switching from OEM supply.
