Bruker Ultraflex-Family MALDI-TOF/TOF Mass Spectrometer — Research Lab Equipment Lot
A Bruker Ultraflex-family MALDI-TOF/TOF system is photo-confirmed in this mixed research-lab lot, but exact generation, workstation/software, vacuum, laser, high-voltage, detector, and removal state are unresolved. The $3,500 conservative system-only model supports REVIEW and a ~$650 blind ceiling.

Why this decision
REVIEW: the mixed lot contains a defensible Ultraflex-family system identity, but exact configuration, function, and heavy removal remain too unresolved for a BUY; use the ~$650 ceiling only as a blind/as-is threshold.
What to verify before bidding
- Ultraflex II-generation appearance does not establish an exact model, suffix, compatibility, or value-bearing options.
- Workstation/software, vacuum hardware, targets, pumps, and accessories are not established.
- No vacuum, laser, high-voltage, detector, or acquired-spectrum performance is demonstrated.

Auction snapshot
This page preserves the September 15, 2026 GSA open-auction observation for item 377412. No observed bid or bidder count is preserved; blank fields are not a $0 result or later auction outcome.
Family-level identity is only the first step for a legacy MALDI system: workstation/software, vacuum, laser, detector, serviceability, and removal can control the bid ceiling.

Independent review not required
No mandatory independent review was required under the current gate. This is not an approval.
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 chassis appears substantially assembled without obvious severe exterior deformation; that is not operating evidence.
Not Established
Not established
- Exact generation/suffix, workstation/software/licenses, vacuum and pump configuration, targets, laser, high-voltage, detector, acquired spectrum, secondary equipment identity, and removal cost.
Manufacturer Context
Independent context
- Bruker lists ultraflex II and III as end-of-life platforms; specialist support remains visible but does not establish serviceability for this unit.
Lotcaliper Assumption
LotCaliper assumptions
- $3,500 conservative whole-lot resale dominated by the untested Bruker system, with no base value for secondary equipment.
- $650 blind maximum hammer after selling, logistics, diagnostics, uncertainty, and required-profit reserves.

Sensitivity and robustness
Requires Verification
The scenarios show potentially workable economics, but the stated verification gate must be resolved before bidding responsibly.
Untested family-level system
- Max hammer
- $650
- Gross resale model
- $2,500–$5,000
At $3,000 conservative resale, the rounded ROI ceiling is about $350; with $1,500 logistics, it is about $150. No value is assigned to unidentified secondary equipment.
Costs and maximum bid
| Transaction / operating cost | Amount | Basis |
|---|---|---|
| Selling Fees | $525 | 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 | $250 | LotCaliper functional-test and diagnostic reserve. |
| Risk Buffer | $350 | Unresolved exact generation, workstation/software, vacuum, laser, high-voltage, detector, heavy removal, and specialist-liquidity risk. |

Family identity, workflow completeness, and heavy-logistics economics
The public identity stays at Bruker Ultraflex-family MALDI-TOF/TOF. An Ultraflex II-generation interpretation is possible, not confirmed, so no exact-generation premium is modeled.
Public market asks show residual specialist and parts value, but asking prices are not realized sales and do not resolve the GSA system's untested vacuum, laser, high-voltage, detector, or workstation state.
- Obtain a readable model plate and inventory workstation, software/licenses, pumps, targets, controllers, cables, and accessories before raising the value basis.
- Demonstrate achieved vacuum, normal laser/interlocks and high voltage, detector response, workstation communication, and a plausible calibration spectrum before treating the system as working.
Recommendation and rationale
Snapshot decision
REVIEWREVIEW: the mixed lot contains a defensible Ultraflex-family system identity, but exact configuration, function, and heavy removal remain too unresolved for a BUY; use the ~$650 ceiling only as a blind/as-is threshold.

Why these confidence levels were assigned
- Identity rationale
- Bruker branding and system architecture support the Ultraflex family, while exact generation remains unresolved.
- Configuration rationale
- The workstation, software, vacuum, targets, pumps, controllers, and accessory configuration are not established.
- Material unknowns: Unbounded
- Condition rationale
- No function is demonstrated across the system's decision-critical vacuum, laser, high-voltage, detector, and acquisition path.
- Material unknowns: Unbounded
- Market Support rationale
- Current exact/related asking evidence and a parts market support residual value but not an exact realized value.
- Costs rationale
- 400–500 kg-class handling is documented in market context, while actual removal and freight remain unquoted.
- Material unknowns: Unbounded
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 · Exact Generation Unresolved
Ultraflex II-generation appearance does not establish an exact model, suffix, compatibility, or value-bearing options.
No readable model or serial plate is preserved.
High · Software And Workflow Unresolved
Workstation/software, vacuum hardware, targets, pumps, and accessories are not established.
The analyzer chassis alone does not prove a usable MALDI workflow.
High · Functionality Unverified
No vacuum, laser, high-voltage, detector, or acquired-spectrum performance is demonstrated.
These are the decision-critical failure modes for an older MALDI system.
