500–5000 µL Pipet Tips, Two-Step Tiered, PP, Natural — 230-1700-03K | 250/Bag | Caplugs® Evergreen

500–5000 µL Reservoir Pipet Tips — Pipetman® Replacement, PP, Natural, 250/Bag (230-1700-03K)

These 500–5000 µL polypropylene pipet tips are precision-molded from virgin PP in a reservoir tip geometry, serving as a direct replacement for Gilson Pipetman® and other large-volume pipettors in the 500–5000 µL class. Supplied non-sterile in 250/Bag, they are engineered for multi-brand compatibility across research, clinical, and quality-control laboratory environments. Natural (clear) construction provides full sample visibility during aspiration and dispensing, enabling immediate confirmation of complete sample delivery and absence of air gaps.

Technical Specifications

Applications

• Large-volume liquid handling and sample transfer requiring full visual confirmation of aspiration
• Serial dilution and reagent dispensing in the 500–5000 µL range
• Viscous solution handling — protein-rich media, glycerol-containing buffers, and similar matrices where standard tips exhibit elevated residual volume
• Cell biology workflows where the wide-bore reservoir opening reduces shear-induced cell damage during transfer
• General clinical chemistry, quality control, and biotech process workflows requiring a reliable large-volume consumable

Compatibility

These tips are engineered as a drop-in replacement for Gilson Pipetman® P5000 and P2000 pipettors, with the reservoir tip shaft geometry providing a positive, leak-free seal at standard Gilson shaft tolerances. Validated fits also include the Eppendorf® Research Plus 5 mL, Thermo Fisher Finnpipette® 5 mL, VWR® Signature™ 5 mL, and Labnet® MultiPette 5 mL — all sharing standard large-volume taper dimensions. Because shaft tolerances vary across pipettor condition and manufacturer, a five-tip aspiration validation is recommended before committing to a high-volume purchase on any brand not previously tested in your specific lab environment. Worn or out-of-tolerance shafts may require additional evaluation regardless of brand.

Chemical Resistance

Quality & Procurement

Made in USA, these Caplugs® Evergreen tips are molded from virgin, FDA-compliant polypropylene resin that is BPA-free and free of phthalate plasticizers. Manufacturing operates under ISO 9001 quality management to ensure consistent lot-to-lot dimensional tolerance — critical for maintaining seal integrity and aspiration accuracy across large-volume protocols. LabSupplies.com is an authorized Caplugs® Evergreen dealer shipping from USA inventory, with tiered pricing available for institutional, hospital, and grant-funded procurement programs.

Frequently Asked Questions

Are these tips sterile?
No — they are supplied non-sterile in 250/Bag bulk packaging. For applications requiring sterility, such as cell culture or nucleic acid work, contact us about sterile tip options in this volume class.

Will these tips fit my Gilson Pipetman® P5000?
Yes — the reservoir tip geometry is validated for the Gilson Pipetman® P5000 and P2000 shafts. As with any OEM replacement tip, a short aspiration validation test is recommended when opening a new lot or switching from OEM supply.

Can I use these tips with viscous samples like glycerol buffers?
Yes. Polypropylene exhibits good resistance to glycerol-containing solutions and protein-rich media, and the reservoir tip geometry minimizes residual volume retention that is common with standard narrow-bore large-volume tips.

What is the pack size, and is larger volume pricing available?
Each bag contains 250 tips. LabSupplies.com offers tiered institutional pricing for laboratories purchasing in higher quantities — contact our procurement team for volume discount information.
