Thermo Scientific Sorvall RC-6 Plus Refrigerated Superspeed Centrifuge — Auction Analysis
This is a photo-confirmed 2010 Sorvall RC-6 Plus Cat. 46910 with a 208 V field setting, but repairable condition, an unshown rotor, dark display, refrigeration uncertainty, and 770 lb logistics leave the blind/as-is ceiling at $0.

Decision at a glance
RecommendationREVIEW
- Maximum hammer bid
- $0
The auction bid ceiling supported by this analysis, if one is defensible; see costs below for buyer-premium treatment.
Why this decision
REVIEW: the immutable $200 observation is above the $0 blind/as-is ceiling, but a useful rotor, clean boot, refrigeration, and a stable test run could justify a newly calculated model.
What to verify before bidding
- Rotor inclusion and identity are unresolved; a closed chamber is not evidence of a missing rotor.
- No boot, alarm, drive, braking, refrigeration, or interlock function is demonstrated.

Auction snapshot
This page preserves the September 14, 2026 lot-specific research observation for sale 2-1-QSC-I-26-387, lot 023: $200 with one bidder. A contemporaneous category display showed no bid; the more specific lot observation is preserved rather than blended with that discrepancy.
For a heavy refrigerated centrifuge, an exact nameplate and intact exterior do not substitute for documented rotor inclusion, refrigeration, drive, interlock, safety, and decontamination evidence.

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
- Cabinet, chamber door, handle, control-panel assembly, and pallet staging are visible without obvious catastrophic exterior deformation.
Not Established
Not established
- Rotor and adapters, power-on, E10–E95 alarm state, drive, braking, refrigeration, door interlock, decontamination, service history, and software level.
Manufacturer Context
Independent context
- Thermo documents the RC-6 Plus at about 350 kg / 770 lb and instructs users to remove a rotor before relocation; tested configured examples are materially stronger market states.
Lotcaliper Assumption
LotCaliper assumptions
- $750 conservative untested whole-unit resale with no rotor value credit.
- $0 blind maximum hammer after freight/rigging, testing, uncertainty, selling, and profit reserves.

Thermo Fisher Scientific Sorvall RC-6 Plus refrigerated superspeed centrifuge, Cat. 46910
Identity confidence: High
Identity evidence
Supplied photographs directly establish the 2010 Sorvall RC-6 Plus, Cat. 46910, 22,000 rpm nameplate, and 208 V field setting.
GSA Auctions · Image · observed September 14, 2026
Configuration
Rotor, lid, buckets, adapters, and tube hardware
Not established · no source evidence establishes presence or absence
Configuration evidence
The chamber is closed; no rotor identity or inclusion is established and no rotor value is credited.

Condition
As-is / repair risk
Seller evidence describes repairable condition with parts potentially missing; the dark display and intact exterior do not establish boot, drive, refrigeration, interlock, or safe run performance.
Evidence confidence: High

Sensitivity and robustness
Requires Verification
The scenarios show potentially workable economics, but the stated verification gate must be resolved before bidding responsibly.
Untested no-rotor-credit model
- Max hammer
- $0
- Gross resale model
- $400–$1,500
The model gives no rotor value credit and reserves freight/rigging, testing, repairable-condition uncertainty, selling friction, and required profit.
Costs and maximum bid
| Transaction / operating cost | Amount | Basis |
|---|---|---|
| Selling Fees | $112.50 | LotCaliper assumption: 15% of modeled gross resale. |
| Shipping | $1,000 | LotCaliper pickup, packing, rigging, and inbound-logistics reserve; not a carrier or GSA quote. |
| Testing Repair Reserve | $200 | LotCaliper functional-test and diagnostic reserve. |
| Risk Buffer | $250 | Repairable condition, unknown rotor, unknown refrigeration and drive state, decontamination, 770 lb removal, and return-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.
Rotor uncertainty, functional proof, and heavy-logistics economics
The market spans failed/parts-level examples, refrigeration-failed surplus, powers-on machines with useful rotors, and tested dealer inventory. This auction evidence cannot be placed in the stronger states without inspection.
The $0 blind ceiling is not a claim that the centrifuge is worthless. It reflects the remote-reseller cost model until a rotor, clean boot, refrigeration, safe run behavior, decontamination, and removal terms are verified.
- Open the chamber and record rotor model, lid, buckets, adapters, corrosion, and damage before assigning configuration value.
- Verify boot, alarms, interlock, a controlled short spin, braking, refrigeration pull-down, and decontamination/removal conditions before rebuilding the valuation.
Recommendation and rationale

REVIEWREVIEW: the immutable $200 observation is above the $0 blind/as-is ceiling, but a useful rotor, clean boot, refrigeration, and a stable test run could justify a newly calculated model.

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 · Rotor Unresolved
Rotor inclusion and identity are unresolved; a closed chamber is not evidence of a missing rotor.
Rotor value and safe operating configuration cannot be inferred.
High · Refrigeration And Drive Unverified
No boot, alarm, drive, braking, refrigeration, or interlock function is demonstrated.
Repairable seller condition and dark display require conservative treatment.
