The P7700-5M is the first macro-volume variable-volume pipette in the Accuris NextPette P7700 family — covering 500 µL to 5 mL for cell-culture media transfer, bulk reagent transfer, sample dilution at mL scale, and other workflow steps where standard high-microliter pipettes (1,000 µL max) are insufficient. Pair with the P7700-T5M 5 mL pipette tips (250/pk at $28) for the macro-volume tip workflow.
Per FQ-017 in fred_followup_queue.md, the NextPette brochure is not in the available corpus; spec details are confirmed from universe label only.

Why a Macro-Volume Pipette vs Serological Pipette
Standard cell-culture and bulk-reagent transfer workflows typically use serological pipettes (1 mL / 5 mL / 10 mL / 25 mL disposable plastic pipettes with bulb pipette aid) for mL-scale liquid handling. The NextPette P7700-5M offers a mechanical alternative with these workflow advantages:
| Feature | Serological pipette + bulb | NextPette P7700-5M (this product) |
| Volume accuracy | Marked to 0.1 mL increments; operator-read | Mechanical volume setting in microliter increments (sub-mL precision) |
| Repeatability | Operator-dependent | Mechanically reproducible |
| Setup time | Snap pipette into bulb each use | Set volume once; pipette repeatedly |
| Tip cost | Disposable serological pipettes | P7700-T5M tip cost (~$0.11 per tip at 250/pk) |
| Workflow | Routine mL transfers | Repetitive precise mL aliquoting (e.g., dispensing the same volume across multiple wells / tubes) |
| Bench footprint | Serological pipette + bulb separate | Single-instrument |
Pick the P7700-5M when: the workflow is repetitive mL-scale aliquoting where mechanical reproducibility matters (cell-culture passaging at standardized volumes, bulk reagent dispensing). Serological pipettes remain the right pick for one-off mL transfers.
NextPette Macro-Volume Pair
| SKU | Volume range | Tip pairing | List price |
| P7700-5M (this product) | 500 µL – 5 mL | P7700-T5M (5 mL tips, 250/pk, $28) | $311 |
| P7700-10M | 1 – 10 mL | P7700-T10M (10 mL tips, 100/pk, $60) | $311 |
The P7700-5M / P7700-10M pair covers the complete macro-volume range from 500 µL up to 10 mL with mechanical pipette accuracy.
Application Profile
Cell-culture media transfer — sub-culture media addition (3–5 mL per flask), media aspiration, trypsin addition workflows.
Bulk reagent dispensing — multi-well buffer dispensing, multi-tube reagent aliquoting at the mL scale.
Sample dilution at mL scale — dilution-series prep where each step is a mL-scale transfer.
Bioreactor sample handling — bioreactor sub-sample collection at 1–5 mL volumes.
Multi-pipette laboratory equipping — labs equipping cell-culture / bioprocess workflows benefit from the macro-volume pipette pair (P7700-5M + P7700-10M) alongside the standard microliter trio (P7700-10 + P7700-100 + P7700-1000).
Tissue-culture core facilities — facilities running daily passaging and media-change workflows benefit from mechanical mL-pipette accuracy for protocol consistency.
Frequently Asked Questions
What volume range does the P7700-5M cover? 500 µL to 5 mL — the first macro-volume pipette in the NextPette P7700 family.
What tips does the P7700-5M use? P7700-T5M 5 mL pipette tips (250/pk, $28). Standard 1,000 µL tips do not fit.
How does the P7700-5M compare to a serological pipette? It sets volume mechanically in microliter increments for reproducible, repetitive mL-scale aliquoting, versus operator-read serological pipettes. Serological pipettes remain the right pick for one-off mL transfers.
What is the recommended calibration interval? Typically every 6–12 months per ISO 8655, following the standard NextPette calibration program.
Is there a larger macro-volume sister? Yes — the P7700-10M covers 1–10 mL ($311), pairing with P7700-T10M tips.
Ordering & Configuration
Pipette tip pairing required. The P7700-5M uses P7700-T5M 5 mL pipette tips (250/pk at $28); confirm tip inventory at order. Standard 1,000 µL pipette tips do not fit the P7700-5M.
Calibration and maintenance. Same calibration program as the rest of the NextPette family — typical 6–12 month interval per ISO 8655.
