Before you order
Two practical cautions for this bench. Ultraviolet transilluminators damage both DNA and the operator: a blue-light unit removes the eye and skin exposure and stops the strand breaks that make downstream cloning fail, and it is the right default unless a stain you are committed to needs UV. And a microplate reader is only as good as its filter or monochromator set — a reader quoted without the wavelengths your assay kit specifies will need an accessory order before it can run anything, so send the kit insert with your enquiry.

Why we publish the standard revision, not just the number.
Testing instruments are bought against a method, and a method is written against a standard. When that standard is revised, the old number stays in circulation for years — sometimes decades — because catalogues copy each other and nobody re-checks.
Three examples currently live across this industry: ASTM D1559 for Marshall stability, withdrawn in 1998. ASTM D422 for hydrometer analysis, withdrawn in 2016. IS 13311 for non-destructive concrete testing, absorbed into the IS 516 family in 2018. All three still appear on product listings you can buy from today.
That matters commercially, not just pedantically. If your quality manual cites a withdrawn standard, a NABL assessor will raise it, and the fastest way that error enters a manual is by being copied off a supplier’s specification sheet.
On qualification: for pharmaceutical customers, the documentation is half the purchase. GMP-specification equipment differs in its contact surfaces, its control system, its printed cycle records and its IQ/OQ/PQ protocol set. Specify that requirement at enquiry stage — retrofitting it after installation costs more and delays qualification.
On site preparation: compression testing machines, ductility baths, abrasion machines and large ovens need foundations, three-phase supply, drainage or extraction. We issue the foundation drawing and utility schedule with the quotation so the civil work can run in parallel with the delivery lead time rather than after it.
