When sourcing high-precision instruments like centrifuges, spectrophotometers, or PCR machines, you must verify the Voltage and Plug Compatibility (e.g., 110V vs 220V) to match your local grid. Ensure the Software Version is provided in a language you support and that Calibration Certificates (NIST traceable) are included. For consumables like Invitrogen or Applied Biosystems reagents, strictly verify the Expiration Dates and Storage Temperature Requirements (e.g., -20°C or -80°C) to ensure biological activity remains intact during transit.
