Thermo Scientific Microm HM 325-2 — Auction Analysis
This repairable Microm HM 325-2 is physically identified as catalog 902100 with visually present specimen-clamp and blade-carrier hardware, but no mechanical or sectioning test is evidenced. The $25 observed bid remains below a $500 blind ceiling that preserves room for repair and precision-feed risk.
Analysis snapshot · Historical — observed August 31, 2026. The scheduled close date of September 2, 2026 has passed. The price, evidence, economics, and recommendation remain exactly as recorded and are not current.

Why this decision
BUY below $500 only for an eligible buyer who accepts repairable precision-mechanical risk; a sectioning or feed test should control any bid increase.

Auction snapshot
At the August 31, 2026 observation, the high bid was $25 with one bidder. This immutable observation is not a final auction result.
A repairable microtome can look configured and complete while still having economically decisive precision-feed and sectioning risk.

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
- Clamp/orienting and blade-carrier hardware appear installed.
- A label reading Inspection Due 06-26 is historical maintenance context, not a passed inspection.
Not Established
Not established
- Exact blade-carrier and clamp part numbers, factory 902100A/902100ER package identity, complete accessories, and all mechanical/sectioning performance.
- A current maintenance inspection, repair diagnosis, or final auction result.
Manufacturer Context
Independent context
- Epredia distinguishes base 902100 from configured 902100A and 902100ER packages; new and dealer pricing are not used resale comps.
Lotcaliper Assumption
LotCaliper assumptions
- $2,500 conservative post-verification resale.
- $500 blind maximum hammer after logistics, testing, missing-accessory, selling, profit, and uncertainty reserves.
Equipment identity
Laboratory · quantity 1
Thermo Scientific / Microm HM 325-2 rotary microtome, catalog 902100
Identity confidence: High
Identity evidence
Physical label and seller description identify Microm HM 325-2, serial 59906, catalog 902100; serial is retained only because the approved specification explicitly requires it.

Configuration
Visually present E-style disposable blade-carrier hardware

Configuration evidence
Visible lower cutting assembly appears consistent with an E-style blade carrier, but no part number is readable.

Configuration evidence
Visible upper specimen assembly appears consistent with a cassette-style quick-release clamp, but no part number is readable.

Configuration evidence
Base catalog 902100 does not establish a 902100A or 902100ER package; waste tray, tools, cover, and documentation are not established.

Condition
As-is / repair risk
Seller classifies the microtome as repairable; no handwheel, feed, retraction, clamp, blade alignment, or actual sectioning performance is evidenced.
Evidence confidence: High
Condition evidence
Seller repairable condition and supplied images provide no precision-mechanical functional test.

No structured comparable-evidence metadata was preserved for this dated snapshot. Public auditability is limited; the numeric resale snapshot cannot be independently audited from comparable records on this page.

The published decision survives the selected downside check under the stated bounded assumptions.
Blind/as-is model
- Max hammer
- $500
- Gross resale model
- $1,500–$2,500
The $500 blind ceiling reserves for repair, accessories, precision verification, selling friction, and uncertainty; the preserved $25 observation is not a final price.
Costs and maximum bid
| Transaction / operating cost | Amount | Basis |
|---|---|---|
| Selling Fees | $375 | LotCaliper assumption: 15% of conservative gross resale. |
| Shipping | $250 | LotCaliper pickup, protective packing, and inbound-shipping reserve; not a carrier quote. |
| Testing Repair Reserve | $300 | LotCaliper cleaning, mechanical verification, and modest refurbishment reserve. |
| Other | $150 | LotCaliper reserve for unresolved accessories and configuration hardware. |
| Risk Buffer | $300 | Precision feed, repairable-condition, and unverified sectioning 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.
Configuration evidence and repairable microtome economics
The base 902100 label and visibly installed hardware can coexist. The asset is published as a configured HM 325-2, not as an unsupported factory package.
The seller's repairable classification controls over exterior appearance. A handwheel movement check alone is not an adequate substitute for feed and sectioning verification.
- Verify the exact blade carrier and specimen clamp, inclusion, feed/retraction, brake, backlash, alignment, and repeatable sectioning before raising the ceiling.
- Do not use new-package, dealer-refurbished, or marketplace asking prices as completed-sale evidence.
Recommendation and rationale
Snapshot decision
BUYBUY below $500 only for an eligible buyer who accepts repairable precision-mechanical risk; a sectioning or feed test should control any bid increase.

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 · Precision Mechanics Unverified
No evidence establishes smooth feed, backlash, retraction, clamp retention, blade alignment, or repeatable sectioning.
A configured exterior does not prove micron-scale mechanical performance.
High · Factory Package Unresolved
Catalog 902100 is not silently promoted to a 902100A or 902100ER package.
The visible clamp and blade-carrier hardware lack readable part numbers.
Medium · Maintenance Status Unverified
The visible Inspection Due 06-26 label is historical maintenance context only.
It does not prove that an overdue June 2026 inspection occurred or passed.
