Technical Narrative
The Caplugs® Evergreen 230-1095-03K is a 1000–5000 µL Reservoir PP Pipet Tip, Natural, 250/Bag, compatible with MLA® pipettors. Reservoir tips feature a wide bore designed for macro-volume dispensing at 1000–5000 µL — the wide-bore construction reduces back-pressure when aspirating and dispensing viscous or large-volume samples, and provides the tip-seat geometry required by large-volume macro pipettor cones. The MLA macro pipettor is used in clinical and industrial laboratories for high-volume reagent and sample dispensing at the 1–5 mL scale.
PP reservoir tip: chemical resistance to standard aqueous, organic, and biological sample types. Low-retention bore minimizes sample residue at macro volumes. BPA-free, phthalate-free,
Procurement economics: $55.98/Bag (250/Bag), $0.2239/tip. Related: 230-1097-B3K (5000-10000 µL Blue Reservoir Oxford 250/Bag). LabSupplies.com ships from USA inventory, typically same business day.

1000–5000 µL Reservoir Tip Tip Applications (MLA)
The is compatible with the following dispensing workflows.
| Application | Setting / Configuration | Notes |
|---|---|---|
| Large-volume sample transfer | MLA® macro pipettor, 1000–5000 µL | Wide bore: low back-pressure for large volumes |
| Reagent dispensing | Manual macro pipettor, bench reagent prep | 250/Bag: adequate supply for reagent prep workflows |
| Media dispensing | Cell culture, media aliquoting | Macro volume: 1000–5000 µL range for flask-to-flask media transfer |
| Buffer preparation | Volumetric buffer dispensing | PP: compatible with standard lab buffers |
| Viscous sample dispensing | Glycerol, serum, protein solutions | Wide bore reduces viscosity-related tip retention |
| Industrial / QC use | Bulk reagent dispensing, large batches | Macro volume range: 1000–5000 µL |
| Standard curve preparation | Calibrator dilution at large scale | Macro pipettor for large-volume standard dilution |
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 1000–5000 µL reservoir PP pipet tips serve clinical, industrial, and research laboratories using MLA macro pipettors for large-volume dispensing. Macro-volume pipettors (1–10 mL range) are used in clinical reference laboratories for bulk reagent preparation, volumetric dispensing of working solutions, and sample aliquoting at scales that exceed standard 200–1000 µL pipettors. The reservoir tip's wide bore accommodates the larger-diameter macro pipettor cone and reduces back-pressure during aspiration of higher-volume samples — critical for accurate delivery of viscous protein solutions, glycerol-based reagents, and serum aliquots at the 1000–5000 µL scale. The 250/Bag format reflects the lower daily consumption of macro-volume tips versus standard bench tips in most lab workflows.

Frequently Asked Questions
Are the pipet tips sterile?
No. Non-Sterile — 250/Bag for general bench use.
What is a Reservoir Tip and how does it differ from a standard Two-Step Tiered tip?
A Reservoir Tip has a wide bore designed for macro-volume dispensing (1000–5000 µL) with macro-volume pipettors. The wide bore accommodates the larger cone diameter of macro pipettors, reduces back-pressure on viscous or large-volume samples, and provides low tip retention at large dispense volumes. Standard Two-Step Tiered tips are designed for 5–1000 µL volume ranges with standard bench pipettor cones.
Is the compatible with all MLA macro pipettor models?
The is designed as a replacement tip for MLA macro pipettors. Verify dimensional compatibility (tip OD, taper, seat length) with your specific macro pipettor model before substituting from OEM supply — test one bag and confirm seal, tip retention, and volume accuracy before bulk purchasing.
