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.

PerformancePLUS plunger assembly for Waters 2695 Alliance

Replaces OEM part number: WAT270959

Plunger assembly for the Waters 2695 Alliance, cross-referenced to WAT270959. The assembled part rather than a bare plunger, which is the safer choice on this pump if you are not confident seating a plunger squarely, because a plunger running even slightly off axis wears its seal on one side and the pump comes back with the same ripple in a few weeks. If you have changed a seal recently and the fault returned, alignment rather than the seal is the thing to look at.

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.

Deuterium lamp for Waters 2489 and 2998 detectors

Aftermarket deuterium lamp for the Waters 2489 and 2998, cross-referenced to 201000281. The 2489 runs at set wavelengths and the 2998 reads the full spectrum, and the same lamp serves both. On either detector, deuterium output falls fastest in the deep UV, so a method running at 210 nm loses sensitivity long before one running at 254 nm does. This detector expects a lamp carrying an RFID tag. The chip is listed in the specification above, and it is worth confirming before you order, because a chipless lamp can be refused by the instrument.

Deuterium lamp for Waters 996 and 2996 PDA detectors

Deuterium lamp for the Waters 996 and 2996 photodiode array, cross-referenced to WAT052586. A PDA reads the whole spectrum at once, which is what makes lamp ageing visible earlier here than on a fixed wavelength detector: pull up a 3D plot and you can watch the deep UV end go noisy while 254 nm still looks fine. Use that before ordering. If the noise is flat across the whole spectrum rather than worst below 250 nm, the lamp is not what is wrong.

Power supply for Waters 2489 HB lamp

Power supply for the Waters 2489 high brightness lamp, cross-referenced to 700002785. This is the part to consider when a new lamp has not fixed the fault. The high brightness lamp needs its supply to strike and hold it, and a failing supply gives you a lamp that will not light, or one that lights and then goes unstable, both of which look identical to a dead lamp from the front panel. If you have already fitted a new lamp and nothing changed, order this rather than a second lamp.

Deuterium lamp for Waters 484 detector

Deuterium lamp for the Waters 484, cross-referenced to WAT080357. The 484 is an old tunable absorbance detector and many are still running, which means the lamp is often not the oldest thing in the light path. Before ordering, check the flow cell windows: years of buffer leave a film that costs you as much signal as a tired lamp and cleans off for nothing. If a cell clean restores your baseline, keep the lamp. If it does not, this is the part.
