Physical Dimension and Fit: The cone and lower barrel of a pipette tip must form a perfect, airtight seal with the specific pipettor or workstation head’s mounting shaft. Even minuscule variations in the diameter, taper angle, or depth of the tip can cause a poor seal. This leads to issues like air gap formation, inconsistent aspiration/dispensing, and tip ejection failures, directly compromising volume accuracy and precision—the very metrics a robotic system is designed to optimize. -
Workstation-Specific Design: Major manufacturers of automated liquid handlers (e.g., Hamilton, Tecan, Beckman Coulter, Agilent, Eppendorf, and many others) often employ proprietary tip designs. These designs are engineered to work seamlessly with their specific tip mounting, ejection mechanisms, and movement profiles. Using a non-branded, “universal” tip can cause mechanical jams, misalignment, or increased wear and tear on the robotic arm, leading to instrument downtime and expensive service calls. -
Material and Manufacturing Tolerances: Beyond shape, the quality of the polymer, the presence of additives (like low-retention surfaces), the molding precision, and the complete absence of contaminants (DNase/RNase, endotoxins, particulates) are paramount. A tip that fits physically but sheds particles or introduces RNases can ruin sensitive next-generation sequencing (NGS) or qPCR experiments. Automated systems, with their high throughput, amplify the impact of any material flaw. -
Application-Specific Requirements: Different protocols demand different tips. A 10µL tip for PCR setup requires ultra-cleanliness and precision, while a 1mL tip for media exchange needs robustness. Filter tips are essential to prevent aerosol contamination and protect the pipettor. A “generic” tip often forces labs to compromise on these application-critical features.
-
Data Variability: Inconsistent liquid handling leads to unreliable results, potentially invalidating entire batches of samples and wasting valuable reagents and time. -
Instrument Downtime: Jams and misalignments halt automated runs, disrupting workflow and delaying projects. -
Cross-Contamination Risk: Non-validated tips may not provide a reliable seal, increasing the risk of sample carryover, especially in sensitive applications. -
Calibration Drift: Poor-fitting tips force the pipettor to work outside its calibrated parameters, leading to gradual inaccuracies.
-
Precision Reverse-Engineering & Mold Development: We can manufacture tips to precisely match the OEM specifications of your specific workstation model, ensuring a perfect physical and mechanical fit. -
Material Selection for Performance: We work with you to select the right polymer grade—from standard polypropylene to ultra-pure, low-retention, or filtered options—tailored to your biological application (e.g., molecular biology, cell culture, genomics). -
Sterilization and Packaging: We provide customized sterilization (gamma irradiation or ETO) and packaging (bulk, racks, stacked plates) to integrate directly into your automated system’s loading process. -
Quality Assurance as Standard: Every batch is produced under strict quality controls, with certificates of analysis available, ensuring the performance and purity you require for reproducible science.
