Technical Narrative
The Caplugs® Evergreen 230-1138-B3K is a 101–1000 µL Two-Step Tiered PP Pipet Tip, Blue, 1000/Bag, as a replacement for Finnpipette® pipettors. The Finnpipette® is a Finnish-designed pipettor widely used in European and molecular biology research laboratories, now part of Thermo Fisher Scientific. The 101–1000 µL blue tip is the primary volume range for the Finnpipette's standard 1000 µL model. Blue 101–1000 µL tip matches the Finnpipette OEM blue tip color convention for the 101–1000 µL range.
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,
Procurement economics: $65.05/Bag (1000/Bag), $0.0651/tip. Related: 230-1467-B3K (100-1000 µL Blue Eppendorf/Pipetman 1000/Bag). LabSupplies.com ships from USA inventory, typically same business day.

| ELISA setup | Antibody, blocker, sample dispensing | 101–1000 µL covers full ELISA reagent volume range |
| Clinical lab pipetting | Serum/plasma dispensing, dilutions | Two-step tiered: secure Finnpipette cone engagement |
| Protein assay | BCA/Bradford protein quantification | Accurate 100–1000 µL dispense for assay setup |
| Research lab general use | 1000/Bag bulk non-sterile supply | Replacement at below-OEM per-tip cost |
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 101–1000 µL two-step tiered blue PP pipet tips serve research and clinical laboratories using Finnpipette® (Thermo Fisher) pipettors as cost-effective OEM replacements. The Finnpipette is widely used in European and molecular biology research environments for its ergonomic design and reliable volume accuracy. The blue color matches the Finnpipette OEM 1000 µL tip color convention, providing visual confirmation of the correct tip for operators transitioning from OEM supply. The 101–1000 µL range covers the full operating range of the Finnpipette 1000 µL model — PCR setup, ELISA reagent dispensing, nucleic acid extraction elution, and cell culture media transfer are the primary applications.

Frequently Asked Questions
Are the pipet tips sterile?
No. Non-Sterile — 1000/Bag for general bench use.
Are these tips compatible with all Finnpipette® models or only the 1000 µL?
The 101–1000 µL range is designed for the Finnpipette 1000 µL model. Finnpipette also offers other volume models (10 µL, 200 µL, 5 mL, etc.) that require different tip sizes. Verify the tip-cone dimensions match your specific Finnpipette model before switching from OEM supply.
Why is the blue if the Finnpipette is also available in other tip colors?
Blue is the OEM color convention for the Finnpipette 1000 µL tip in the 101–1000 µL range. Matching the OEM color enables laboratory staff to identify the correct tip size by color without retraining when transitioning to Caplugs Evergreen replacement tips. Other Finnpipette volume models may use different color conventions.
