Applied Biosystems PCR Pair + Bio-Rad Reader — Auction Analysis
Two Applied Biosystems 7300/7500-generation PCR instruments and an unidentified Bio-Rad reader are interesting only at family level. With no confirmed PC/software, calibration, functional proof, exact variant, reader identity, or credible shipment weight, the $505 observed bid exceeds the ~$400 blind ceiling.

Why this decision
SKIP: the preserved $505 bid is above the ~$400 blind/as-is ceiling, which assigns no conservative value to the model-unresolved Bio-Rad reader.

Auction snapshot
This page preserves the September 13, 2026 GSA observation for sale 1-1-QSC-I-26-293, lot 006: $505 with two bidders. It does not replace that observation with later auction state.
A PCR chassis family, a seller's usable statement, and a generic reader label are not enough to justify exact-model, calibration, software, or freight assumptions.

How independent review worksHow evidence is classified
Seller facts, photo-derived observations, manufacturer context, unknowns, and LotCaliper assumptions remain explicitly separated.
Photo Derived
Photo-derived
- The PCR housings appear substantially intact; no dedicated control workstation is visible.
- The Bio-Rad reader is present but not visible in sufficient detail for model identification.
Not Established
Not established
- Exact PCR variants, whether both units match, block format, reader model, PC/software/entitlement, thermal/optical performance, calibration, maintenance history, and actual total shipment weight.
Manufacturer Context
Independent context
- Thermo Fisher documentation distinguishes the standard 7500 and 7500 Fast block formats and shows computer/software and recurring calibration/verification as material system requirements.
Lotcaliper Assumption
LotCaliper assumptions
- $2,500 conservative whole-lot resale for two family-level PCR instruments; the unresolved Bio-Rad reader receives zero conservative value.
- ~$400 blind maximum hammer after selling friction, realistic packing/logistics, testing, risk, and required profit.

Applied Biosystems Two 7300/7500-generation real-time PCR instruments; exact model and Fast/standard configuration unresolved

The seller states two Applied Biosystems PCR systems; the supplied photograph supports family-level 7300/7500/7500 Fast generation identity but no readable model plate.

Sensitivity and robustness
Fails
The modeled economics fail the standard reseller requirements under the stated assumptions.
Blind family-level whole-lot model
- Max hammer
- $400
- Gross resale model
- $1,200–$3,500
The ~$400 ceiling values two seller-reported-usable but unverified PCR instruments, assigns zero conservative value to the unresolved Bio-Rad reader, and reserves for realistic packing, testing, risk, fees, and profit.
Costs and maximum bid
| Transaction / operating cost | Amount | Basis |
|---|---|---|
| Selling Fees | $375 | LotCaliper assumption: 15% of modeled gross resale. |
| Shipping | $500 | LotCaliper pickup, packing, rigging, and inbound-logistics reserve; not a carrier or GSA quote. |
| Testing Repair Reserve | $300 | LotCaliper functional-test and diagnostic reserve. |
| Risk Buffer | $400 | Exact-model, PC/software, calibration, optical/thermal, reader, and unreliable-weight risk reserve. |

This is a reseller ceiling, not a prediction of the auction's closing price. Any buyer premium or other unquoted acquisition charge must be deducted before bidding.
PCR variant, software, calibration, and freight risk
The seller's usable wording remains a seller assertion. No boot, self-test, computer communication, thermal cycle, optical readout, calibration, or known-control result is demonstrated.
GSA's 106 lb total-lot field conflicts with manufacturer weights: two 7300-family units alone exceed that figure before the reader. Freight requires a real weight or conservative physical planning, not the displayed field.
- Get readable model/serial labels for both PCR instruments and the reader; confirm standard versus Fast block configuration.
- Verify control-PC communication, self-test, thermal/optical performance, calibration history, and the actual packed or scale weight before assigning working-system value.
Recommendation and rationale
Snapshot decision
SKIPSKIP: the preserved $505 bid is above the ~$400 blind/as-is ceiling, which assigns no conservative value to the model-unresolved Bio-Rad reader.

Market support assesses how well the available evidence supports the resale assumption. Exact third-party marketplace records may be omitted when source-use rights are unclear. Each dimension uses the published methodology rubric; a confidence label measures the strength and boundedness of its evidence, not the likelihood of a profitable outcome.
Risks and unknowns
High · Model And Calibration Unresolved
Exact PCR variants, control/software path, thermal/optical performance, and calibration are not established.
Family-level appearance and seller-reported usable condition do not prove qPCR-ready performance.
High · Listed Weight Unreliable
The 106 lb stated total conflicts with manufacturer weights for two 7300/7500-family instruments before the Bio-Rad reader.
Freight must not be modeled from an internally inconsistent auction weight field.
