SPECTRONIC 20D+ Digital Spectrophotometer — GSA Auction Analysis
The seller identifies a SPECTRONIC 20D+ but its 2115NR identifier is unresolved against the manufacturer 333183 family. Power, lamp, wavelength, photometric performance, calibration, and accessories are untested; the $150 model supports a $0 blind ceiling.

Auction snapshot
This page preserves the 2026-09-14 GSA open-auction observation for sale 3-1-QSC-I-26-577, lot 002, item 376732. No numeric high bid or bidder count was preserved; blank fields are not a $0 result.
A seller-entered identifier must not be converted into a manufacturer catalog number without label evidence, and a real low-hundreds market may still fail professional-reseller economics.

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
- No supplied photograph is required to support the conservative family-level public conclusion.
Not Established
Not established
- No power-on, lamp, wavelength accuracy, photometric accuracy/linearity, calibration, or serial-I/O result is established.
- Seller and manufacturer dimensions/weight differ; actual packed shipping data is not established.
Lotcaliper Assumption
LotCaliper assumptions
- $150 conservative gross resale under the approved whole-lot basis.
- $0 blind maximum hammer under the standard LotCaliper professional-reseller profile.

Evidence recency

Three recent exact-model completed listings cluster around $150–$190, while current exact-model asks run roughly $100–$300 and are not realized sales.

Sensitivity and robustness
Fails
The modeled economics fail the standard reseller requirements under the stated assumptions.
Blind/as-is standard profile
- Max hammer
- $0
- Gross resale model
- $150–$250
A positive hammer requires buyer-specific lower costs or stronger verified condition and resale evidence; neither is assumed.
Costs and maximum bid
| Transaction / operating cost | Amount | Basis |
|---|---|---|
| Selling Fees | $22.50 | LotCaliper assumption: 15% of modeled gross resale. |
| Shipping | $50 | LotCaliper pickup, packing, rigging, and inbound-logistics reserve; not a carrier or GSA quote. |
| Testing Repair Reserve | $75 | LotCaliper functional-test and diagnostic reserve. |
| Risk Buffer | $50 | LotCaliper reserve for untested condition, verification, repair, return, and liquidity uncertainty. |

Identity, condition, and blind economics
The stated range, filter regions, concentration mode, and interface match the 20D+ family, but 2115NR is not established as an official manufacturer catalog number.
Three recent exact-model completed listings cluster around $150–$190, while current exact-model asks run roughly $100–$300 and are not realized sales. SKIP: at $150 conservative resale, selling friction plus $50 logistics, $75 test reserve, $50 uncertainty, and the $500 profit requirement fail before acquisition cost.

Why these confidence levels were assigned
- Identity rationale
- The stated range, filter regions, concentration mode, and interface match the 20D+ family, but 2115NR is not established as an official manufacturer catalog number.
- Configuration rationale
- Exact 333183 voltage suffix, normal cuvette/adapter accessories, and optional serial-interface accessories are not established.
- Material unknowns: Bounded
- Condition rationale
- No functional, calibration, or service evidence bounds the material condition risk.
- Material unknowns: Unbounded
- Market Support rationale
- Three recent exact-model completed listings cluster around $150–$190, while current exact-model asks run roughly $100–$300 and are not realized sales.
- Material unknowns: Bounded
- Costs rationale
- Logistics and verification are buyer-specific reserves rather than quotes.
- 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 · Function Unverified
No power-on, lamp, wavelength accuracy, photometric accuracy/linearity, calibration, or serial-I/O result is established.
The supplied evidence does not demonstrate the value-bearing function.
High · Profit Floor Failure
The standard absolute-profit requirement fails even at a zero hammer.
