The Guanshentai Automatic Pipette Leak Tester is a specialized machine designed for the fully automated inspection of sealing performance and leak defects in long, tubular containers such as pipettes, Pasteur pipettes, and droppers. Integrating automatic feeding and sorting, multi-station sealing and clamping, positive/negative pressure testing, and pressure-decay-based sorting, the system automates the entire process—from handling bulk tubes to outputting qualified products. It achieves testing speeds of 600–1,800 units per hour, effectively replacing traditional manual methods involving water immersion, visual inspection, or random sampling.

Key Advantages:
High-Precision Micro-Leak Detection: Utilizing high-sensitivity pressure sensors and a precision pneumatic control system, the machine tests the sealing integrity of each pipette via pressure decay or flow-rate methods. It accurately identifies defects such as micropores, nozzle cracks, tip damage, and poor seal interfaces, achieving micro-pressure level detection accuracy.
Flexible Sealing and Clamping: Designed to handle pipettes with high aspect ratios and thin walls, the machine employs a flexible clamping mechanism with adjustable, controlled force. This ensures a reliable seal at the nozzle while preventing wall damage or nozzle deformation.
Automatic Assessment and Rejection: Users can preset pressure decay thresholds on the touchscreen; the system automatically evaluates pass/fail status upon completion. Defective units are automatically rejected into a waste collection area via air blast or robotic arm, while qualified products are counted and discharged, ensuring consistent sealing performance for all outgoing products.
Multi-Specification Compatibility: By swapping sealing fixtures and adjusting testing parameters, the machine accommodates various pipette sizes (0.1ml–10ml), lengths (50–300mm), and diameters (3–15mm), allowing for flexible and convenient product changeovers.
Clean and Dust-Proof Design: The machine features an SUS304 stainless steel frame and an enclosed protective structure. With a controlled, clean testing zone, it is suitable for operation in cleanrooms, meeting the environmental standards required for the production of laboratory and medical consumables. +
Applications: Ideally suited for large-scale, standardized leak testing in the production of life science consumables (such as pipettes, serological pipettes, Pasteur pipettes, and disposable droppers), in vitro diagnostic consumables (sample and reagent droppers), and other medical consumables. With its high-efficiency, high-precision, and non-destructive testing capabilities, the Guanshentai automatic pipette leak tester enables manufacturers to implement comprehensive seal quality control, ensuring products meet the necessary standards for sealing integrity and pipetting accuracy during use.
