How to Choose HPLC and UPLC Spare Parts
Choosing an HPLC or UPLC spare part starts with the exact instrument model and component part number. A product photograph helps identify the component, while the label and manufacturer documentation provide the details needed to compare it with the part being replaced. Use this checklist when requesting a quotation from AliHPLC.
1. Collect the instrument and component details
Record the manufacturer, instrument family, module model and serial number. Photograph the existing component label and include any assembly or revision number shown. For a complete assembly, identify which fittings, cables, brackets and related items are required.
- Instrument and module model, such as an ACQUITY TUV detector or H-Class QSM.
- Part number from the existing component or packaging.
- Clear photographs of the label, connectors and mounting points.
- Quantity required and delivery country or postal code.
Browse our HPLC and UPLC spare parts by part number, then compare the individual listing with these details.
2. Check the specific flow-cell configuration
Waters identifies 205015033 as an ACQUITY TUV low dispersion analytical flow cell and 205015016 as an analytical flow cell. The packaging shown in our 205015033 flow-cell listing is labeled 10 mm and 500 nL.
For a flow cell, confirm the detector, part number, path length, cell volume and the supplied inlet and outlet tubing. Use Waters flow-cell part guidance when comparing the documented configurations.
3. Identify the valve or pump assembly
The Waters 700005161 component is a dual-channel gradient proportioning valve for the ACQUITY H-Class Quaternary Solvent Manager. Waters documents this component in its H-Class GPV part guidance.
When requesting a valve, actuator, plunger drive or degasser assembly, specify the component type as well as the part number. Ask which cables, tubing, fittings and mounting hardware are included in the listing. A clear photograph of the existing installation helps make the inquiry specific.
4. Review condition and available test information
Read the listed condition and request available test records, additional photographs or a demonstration video when useful. Describe the component or system you need so the inquiry can be checked against the item being offered. For a software workstation, specify the software version, instrument connections and license information to be confirmed.
Warranty periods, covered items and return terms vary by listing. Confirm the applicable terms in the product description and written quotation, including any exclusions and return arrangements.
5. Request a complete quotation
Send the product link, part number, instrument details, quantity and delivery destination through our contact page. Include questions about condition, included accessories, available tests, warranty and shipping. This gives the inquiry enough context to assess the listed component.
For a full instrument purchase, review our used laboratory equipment buying guide and laboratory equipment collection. Confirm the modules, detector, workstation and accessories that should appear on the quotation.
