Gilian Gilibrator-2 Calibration Instrument Lot — Auction Analysis
The seller's three identifiers do not establish three complete calibrators: the photographs instead support two legacy Gilibrator-2 control bases, about four wet-cell assemblies, two cases, power accessories, solution hardware, and a likely printer. With power, cell identity, leak-free operation, and calibration unresolved, the $50 observed bid remains attractive only below a roughly $150 blind hammer ceiling.

Why this decision
BUY at the preserved $50 observation, subject to a roughly $150 blind hammer ceiling; the modular inventory looks useful, but power, batteries, wet-cell identity, leak-free operation, printer function, and calibration remain unresolved.

Auction snapshot
At the August 27, 2026 observation, the high bid was $50 with two bidders. This immutable observation remains $50 after the scheduled close rather than becoming a live or final-price record.
A seller's ‘three instruments’ description can hide a more valuable—but different—modular inventory. Separating control bases, wet cells, kit part numbers, and calibration status matters more than counting seller line items.

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
- Two legacy serial-interface Gilibrator-2 control bases, two hard cases, chargers, tubing, and solution dispensers.
- Approximately four wet-cell assemblies; the richer case appears to span low-, standard-, and high-flow sizes. A likely printer accessory is not confirmed working.
Not Established
Not established
- Power-on, battery condition, printer operation, leak-free wet-cell operation, or current calibration/service.
- Exact identity and flow range of every photographed cell; 904033 and 14195 are not promoted to confirmed serials.
Manufacturer Context
Independent context
- Sensidyne documentation identifies 800271 as a standard-flow wet-cell kit part number, not reliable serial evidence.
- Official context places low flow around 1–250 cc/min, standard flow around 20 cc/min–6 L/min, and high flow around 2–30 L/min.
Lotcaliper Assumption
LotCaliper assumptions
- $1,500 conservative gross resale; $600 non-acquisition burden excluding selling fees and hammer.
- 15% selling cost, $500 minimum profit, 30% minimum ROI, and a roughly $150 maximum hammer.

Blind/as-is modular-lot model
- Max hammer
- $150
- Gross resale model
- $1,500
At the preserved $50 observation, modeled profit is about $625 and ROI about 96%. The bid observation remains immutable after close.

| Testing Repair Reserve | $300 | LotCaliper functional-test and diagnostic reserve. |
| Risk Buffer | $175 | Battery, repair, accessory, wet-cell identity, leak, printer, and calibration uncertainty. |

Modular configuration, calibration risk, and economics
The seller lists 800271 as a serial number, but official documentation identifies it as a standard-flow kit part number. The listing's three identifiers therefore do not prove three complete calibrators.
The photographs establish a surprisingly complete modular set, but not a calibrated one. A buyer should assume the cells and bases need evaluation until current calibration or service evidence is produced.
- Verify both bases power and communicate, inspect batteries, and leak-test each wet cell.
- Read every cell label before assigning low-, standard-, or high-flow resale value.
- Test the probable printer separately and do not value the lot as two current-generation bases.
Recommendation and rationale
Snapshot decision
BUYBUY at the preserved $50 observation, subject to a roughly $150 blind hammer ceiling; the modular inventory looks useful, but power, batteries, wet-cell identity, leak-free operation, printer function, and calibration remain unresolved.

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 · Seller Metadata Error
The seller's three identifiers do not prove three complete calibrators.
Official kit documentation and photo reconstruction conflict with the listing shorthand.
High · Kit Part Number Mislabeled As Serial
800271 is a standard-flow wet-cell kit part number, not reliable serial-number evidence.
Official Sensidyne/Gilian documentation.
Medium · Modular Configuration Reconstructed From Photos
The value-bearing inventory is reconstructed from components visible across two cases.
Photo-derived evidence, with individual cell ranges partly unresolved.
High · Functionality Unverified
Neither control base, wet cell, nor probable printer is shown operating.
No powered or functional evidence.
High · Calibration Unverified
No current cell calibration or service evidence is supplied.
Absence of current documentation or test evidence.
Medium · Legacy Generation
Both bases appear to be the older serial-interface generation.
Photo-derived enclosure and interface evidence.
Medium · Cell Identity Partly Unresolved
Approximate cell count and range mix are visible, but individual labels are not readable.
Photo resolution limits.
