1000–5000 µL Reservoir Pipet Tips — MLA® Compatible, Polypropylene, Natural, 250/Bag (230-1095-03K)
These large-volume polypropylene reservoir tips cover the 1000–5000 µL working range and are designed as a direct replacement for MLA® pipettors. The wide-bore reservoir tip body accommodates high-volume liquid transfers without restriction or clogging, making them well suited to bulk reagent dispensing, serial dilutions, and specimen processing in clinical and research laboratories. Supplied non-sterile in 250/Bag bulk format, part number 230-1095-03K delivers cost-effective, consistent tip supply for labs running MLA® instruments in daily workflows.

Applications
- High-volume reagent dispensing in clinical chemistry and immunoassay workflows
- Serial dilutions and sample preparation requiring transfers in the 1–5 mL range
- Viscous reagent and cell suspension handling, where the wide-bore reservoir body prevents restriction
- Bulk specimen processing in hospital, biotech, and pharmaceutical laboratories
- High-throughput pipetting runs on MLA® instruments requiring reliable, consistent tip fit
Compatibility
These reservoir tips are engineered as a drop-in replacement for MLA® pipettors operating in the 1000–5000 µL volume class. The reservoir tip shaft profile is matched to the large-volume tip channel geometry of MLA® instruments, providing a positive seal and accurate liquid delivery without modification to your existing workflow. As with any OEM replacement, confirm your specific MLA® pipettor model accepts this volume and tip format before transitioning from factory-supplied tips.

Frequently Asked Questions
Are these tips sterile?
No — they are supplied non-sterile in 250/Bag bulk packaging, which is appropriate for most clinical chemistry, reagent dispensing, and sample preparation workflows that do not require sterile tips.
What makes a "reservoir tip" different from a standard large-bore tip?
A reservoir tip features a wide-bore body with an enlarged internal channel designed to handle the full 1000–5000 µL volume range without restriction. This geometry is especially important for viscous reagents, cell suspensions, and high-volume transfers where a narrower tip body could impede flow or introduce inaccuracy.
Will these tips fit pipettors other than MLA®?
These tips are specifically engineered to match the cone geometry of MLA® pipettors. Compatibility with other pipettor brands in the same volume class has not been confirmed in the provided specifications, so we recommend verifying fit against your instrument before switching supply.
What is the natural color useful for in the lab?
The natural (clear) polypropylene allows direct visual inspection of the liquid column during aspiration and dispensing, letting technicians quickly confirm sample uptake and detect air gaps or bubbles — a practical benefit during high-volume specimen processing.
