Autosampler Parts and Supplies

Your autosampler is designed to deliver accurate measurements, precise injection volumes, and high-quality data. And by following a regular schedule of preventive maintenance, you can ensure a lifetime of defensible results.

HPLC autosampler parts are essential for accurate, reproducible sample introduction, helping to maintain precise injection volumes, reduce carryover, and support reliable chromatographic performance. Key components such as needles and needle seats, injection valves, rotor seals, injection loops, metering device seals, needle wash components, and HPLC vial trays all play an important role in preventing leaks, minimising contamination, and protecting data quality. 

At Crawford Scientific, we offer a range of HPLC autosampler parts, spares, and consumables to support routine servicing, repair, and ongoing instrument care. Replacing worn or contaminated components such as needles, needle seats, rotor seals, syringe seals, and wash station parts helps maintain injection accuracy, reduce ghost peaks and carryover, and keep autosamplers operating efficiently. Whether you are troubleshooting poor reproducibility, addressing leaks, or keeping essential autosampler spares available in the lab, high-quality replacement parts help support reliable performance across HPLC workflows.
