This is an aftermarket part, not an original manufacturer part. Instrument names and part numbers identify what it fits and replaces; they remain the trademarks of their owners. The manufacturer, country of origin, rated life and warranty are stated in the quote, before you decide anything. If you need the OEM part, say so and I will quote that instead.

Viper sample needle for Thermo WPS-3000 autosamplers

Replaces OEM part number: 6820.2432

Viper sample needle for the WPS-3000, cross-referenced to 6820.2432. Viper fittings are finger tight by design and that is the part people get wrong: over tightening with a tool deforms the cone and produces exactly the dead volume the fitting exists to avoid. A bent or blunted needle tip damages the seat below it, so if you are fitting a new needle it is worth inspecting the seat at the same time. Peak shape that has gone slightly tailing on every compound, rather than one, is worth checking here.

Before you order: if the instrument is misbehaving, tell me the symptom, not the part number. Lamps and seals get replaced for problems they did not cause. The first look costs nothing, and if this part is not the fix, I will say so.
