This is what a buyer checks before they shortlist machinery and equipment suppliers.
What does a laboratory check before buying an instrument?
They check the performance specification against the method, whether you support installation and operational qualification, and the consumable and service costs. In regulated laboratories an instrument that cannot be qualified cannot be used, whatever it measures.
A laboratory manager is buying an instrument that must be qualified, maintained and defended in an audit for a decade.

First, what the product is
The fields a buyer scans before deciding whether you are worth contacting. Missing one of them usually ends the visit without an email.
- 1
Instrument type and technique
The category the laboratory is shopping in.
- 2
Performance specification
Range, accuracy, precision and detection limit.
- 3
Methods and standards supported
Whether it runs the laboratory's existing methods.
- 4
Qualification support
Installation and operational qualification for regulated laboratories.
- 5
Consumables and their cost
Frequently exceeds the instrument cost over its life.
- 6
Data system and compliance features
Audit trail and record integrity in regulated work.
- 7
Footprint and services required
Bench space, power, gases and extraction.
Then the paperwork
Naming the documents you can issue is what separates a supplier who can be audited from one who cannot.
| Document | What it proves | Where it belongs |
|---|---|---|
| Technical specification sheetAsked at: selection | Performance parameters with the conditions they are measured at | Publish it |
| Qualification documentationAsked at: regulated laboratories — often decisive | Installation and operational qualification protocols | Publish it |
| Calibration certificateAsked at: installation and periodically | Calibration traceable to recognised standards | Per shipment |
| Method compliance statementAsked at: method transfer | Which standard methods the instrument supports | Publish it |
| Declaration of ConformityAsked at: before installation | Conformity with electrical safety and applicable directives | Publish it |
| Service coverage and response timeAsked at: purchase decision | Engineer coverage, response and preventive maintenance scope | Publish it |
| Consumable and spare parts price listAsked at: total cost evaluation | Running cost over the instrument's life | Publish it |
The shortlist moment
A buyer lines up a few suppliers and keeps the ones whose proof is easy to check. The rest get a closed tab, not an email.
The buyer asks: What does a laboratory check before buying an instrument?
A few suppliers get compared side by side:
A supplier with Technical specification sheet on the page
Performance parameters with the conditions they are measured at
A supplier with Qualification documentation on the page
Installation and operational qualification protocols
A supplier with Method compliance statement on the page
Which standard methods the instrument supports
Is one of them you?

Questions suppliers ask
Why publish consumable prices?
Because sophisticated buyers calculate cost per sample, and those are the buyers worth having. Publishing consumable costs signals confidence, and it wins against competitors whose instrument is cheaper and whose consumables are not. Buyers discover it eventually either way.
What does qualification support actually need to include?
Protocols and documentation for installation and operational qualification, and clarity about whether your engineer performs them. Regulated laboratories cannot use an unqualified instrument, so this is a gate rather than a preference, and vagueness reads as absence.
How much application data belongs on the site?
Application notes for the methods your customers actually run are among the most valuable pages you can publish. Laboratory buyers search for their method rather than for an instrument category, and a note that shows the instrument running that method is what gets found.
Documents and standards named here are the ones buyers in this industry commonly ask for; requirements vary by market, customer and contract, so treat this as a starting checklist rather than a compliance list. Clearer pages can help discovery and evaluation. They do not guarantee rankings, AI citations, enquiries or revenue.
