Before you order
A chromatograph is never a single purchase. An HPLC needs its column, its detector chosen against the analyte, mobile-phase solvents at the right grade, and somewhere for the waste to go; a GC needs carrier gas at chromatographic purity, which is why the gas generators sit in this category rather than under utilities. Generators are worth costing properly against cylinders: they remove the cylinder-change interruption and the regulator, and they pay back over the instrument lifetime, but they add a maintenance item. Send us the method you are running and we will quote the system, the consumables and the gas supply as one list.

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Three examples currently live across this industry: ASTM D1559 for Marshall stability, withdrawn in 1998. ASTM D422 for hydrometer analysis, withdrawn in 2016.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 If your quality manual cites a withdrawn standard, a NABL assessor will raise it, and the fastest way that error enters a manual is by being copied off a supplier’s specification sheet.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.
