CEM MARS Xpress Microwave Digestion System — GSA Auction Analysis
CEM/MARS Xpress branding supports a probable 907501-family identity, but conflicting seller metadata, unverified chamber contents, and no functional proof leave no positive blind hammer.

Auction snapshot
This page preserves the September 26, 2026 GSA open-auction observation for item 378200, sale 1-1-QSC-I-26-330, lot 015. No numeric high bid or bidder count was preserved; blank fields are not a $0 result.
A closed microwave chamber hides the accessory and sensor inventory that determines whether a chassis is a recoverable system.

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
- Supplied auction photos support physical observations only, not function.
Not Established
Not established
- Exact rear-plate model/serial, turntable, carousel, vessels, sensors, accessories, startup, interlocks, microwave power, calibration, and freight are not established.
Manufacturer Context
Independent context
- Current 907501-family asks span parts/repair through tested/warrantied condition; no qualified realized sale is retained.
Lotcaliper Assumption
LotCaliper assumptions
- $1000 conservative resale under the approved blind basis.
- $0 blind maximum hammer under stated reserves and return requirements.

Why these confidence levels were assigned
- Identity rationale
- The supplied photo directly shows CEM and MARS Xpress branding, enclosure, door, viewing window, and integrated controls.
- Material unknowns: Bounded
- Configuration rationale
- Exact rear-plate model/serial, turntable, carousel, vessels, sensors, accessories, startup, interlocks, microwave power, calibration, and freight are not established.
- Material unknowns: Unbounded
- Condition rationale
- Seller states used condition with possible missing parts and repairs; no function is supplied.
- Material unknowns: Unbounded
- Market Support rationale
- Current 907501-family asks span parts/repair through tested/warrantied condition; no qualified realized sale is retained.
- Material unknowns: Bounded
- Costs rationale
- Costs are buyer-specific and 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.
