Catch Spring for Tip-Tray Holder

A compact replacement retention spring, this part fits the tip-tray holder on QIAGEN automated primary sample technology workstations such as the QIAsymphony SP and AS modules. Its job is to apply calibrated clamping force so that disposable tip racks and reagent trays stay locked in position through thousands of pipetting cycles, preventing tip pickup errors, tray drift, and partial ejection events during automated pipetting.

Over time the factory-installed spring can fatigue or fracture from repeated loading, which shows up as failed tip pickup or visible play in the tray carriage. Swapping in a new catch spring restores the original seating pressure and extends the service life of the surrounding holder without replacing the whole module. Installation is a straightforward field service task for laboratory technicians performing scheduled preventive maintenance, requiring only basic hand tools and a clean bench.

• Role: retention catch spring for the tip-tray holder assembly
• Material: corrosion-resistant stainless steel wire
• Compatible instruments: QIAGEN QIAsymphony SP and AS primary sample technology systems
• Pack format: single-piece service spare
• Use case: preventive maintenance and repair of the tip-tray carriage

Keep the spring in a dry area at room temperature, away from dust, oils, and corrosive vapors that could degrade the metal before installation. Intended for research use only, this mechanical spare supports continuous uptime of high-throughput nucleic acid extraction, assay setup, and other automated liquid handling runs that depend on reliable tip and tray retention.
