The P7700-200 is the 20 to 200 µL mid-high microliter variable-volume pipette in the Accuris NextPette P7700 family — used for cell-culture sample handling, master mix aliquoting, ELISA wash buffer addition, and other workflow steps where the 20–200 µL range delivers better accuracy than the broader P7700-100 (10–100 µL) at its top, or the P7700-1000 (100–1,000 µL) at its bottom.
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.

Key Specifications
| SKU | P7700-200 |
| Type | Manual variable-volume pipette |
| Volume range | 20 µL to 200 µL (mid-high microliter) |
| Family position | Between P7700-100 (10–100 µL) and P7700-1000 (100–1,000 µL) — overlap range |
| Workflow context | Cell-culture sample handling, master mix aliquoting, ELISA wash buffer addition |
P7700-200 vs P7700-100 vs P7700-1000 — Pick the Right Pipette in the Overlap Range
| Pipette | Volume range | Best at | Trade-off |
| P7700-100 | 10 – 100 µL | 25–100 µL accuracy | 100 µL is at the top of range |
| P7700-200 (this product) | 20 – 200 µL | 50–200 µL accuracy — workhorse for the 100–200 µL band | 20 µL is at the bottom of range (10 % of range) |
| P7700-1000 | 100 – 1,000 µL | 250–1,000 µL accuracy | 100 µL is at the bottom of range (10 % of range) |
Pick the P7700-200 when:
- The workflow's primary pipetting volumes are in the 100–200 µL range — operating at 50–100 % of range delivers best accuracy
- The lab needs higher accuracy at 100 µL than the P7700-100 (top) or P7700-1000 (bottom) can deliver
- The workflow is cell-culture sample handling at 100–200 µL volumes (passaging aliquots, viability-stain dilutions, sub-culture transfers)
Skip the P7700-200 when: the workflow's primary volumes are < 100 µL (use P7700-100), or > 200 µL (use P7700-1000).
Application Profile
Cell-culture sample handling — the workhorse application. Sub-culture aliquoting at 100–200 µL volumes; viability-stain dilution preparation; cell-counting sample prep at 100 µL volumes.
Master mix aliquoting — multi-reaction master mix preparation with per-reaction aliquoting at 100–200 µL volumes.
ELISA wash buffer addition — standard ELISA wash buffer at 100–200 µL per well; substrate addition at 100 µL per well.
Magnetic-bead extraction wash buffers — wash buffer aliquoting at 100–200 µL per sample.
Standard immunoassay workflows — sample addition, antibody addition, wash buffer addition at 100–200 µL volumes.
Multi-pipette laboratory equipping — labs equipping new bench setups for cell-culture / immunoassay workflows benefit from the P7700-200 for the 100–200 µL workflow density.
Frequently Asked Questions
Q: What is the volume range of the P7700-200? A: 20 µL to 200 µL — the mid-high microliter band, with best accuracy in the 100–200 µL range.
Q: Which pipette tips does the P7700-200 use? A: Typically 200 µL low-retention tips (same tip format as the P7700-100); confirm tip-format compatibility at order.
Q: Should I choose the P7700-200 or the P7700-100? A: Pick the P7700-200 when the workflow's primary volumes are in the 100–200 µL range; use the P7700-100 for volumes below 100 µL and the P7700-1000 for volumes above 200 µL.
Q: Who makes the P7700-200? A: It is part of the Accuris NextPette P7700 manual variable-volume pipette family, listed.
Ordering & Configuration
