KLS Series High-Low Temperature Linear Module | Used for Biomedical Genetic Sampling

Core Perspective: Balancing "low-temperature sample viability" with "contamination prevention" in automated workflows
The core dilemma of automated genetic sampling equipment is that sample viability demands a consistently cryogenic environment (-196°C liquid nitrogen), while mechanical transmission systems conventionally freeze and fail at such temperatures due to lubricant solidification. The KLS Series High-Low Temperature Linear Module resolves this contradiction. This high-low temperature linear module is specifically optimized for low-temperature automation in the biomedical industry, focusing on startup torque characteristics. When the ambient temperature plummets to min -196°C, standard motors suffer step-loss as the coercivity of their magnets degrades. In contrast, this high-low temperature linear module employs samarium-cobalt (SmCo) cryogenic-grade magnets, ensuring rated torque output even at liquid nitrogen temperatures.
During the lysis step of nucleic acid extraction, the equipment may rapidly heat to max +200°C to inactivate proteases. The housing of this high-low temperature linear module undergoes special heat treatment to withstand repeated thermal stress without distortion. For sterile sampling requirements, the surface of this high-low temperature linear module is coated with a material resistant to ethanol and vaporized hydrogen peroxide (VHP), with a seamless, crevice-free design facilitating cleaning validation. Operating under a vacuum degree of 10^-7Pa, this high-low temperature linear module suits next-generation fully enclosed sterile sampling systems, effectively preventing cross-contamination. Remarkably, the KLS Series High-Low Temperature Linear Module withstands radiation intensity of 10^6Gy, meaning it will not become a source of radiation-induced degradation when used on production lines for radiation-sterilized vaccines.
Regarding mechanical selection, the miniature body width of 30mm high-low temperature linear module can be directly embedded into the sampling platform of a microfluidic chip. Its repeatability of ±0.01mm ensures precise alignment between the pipette tip and the microwell. Meanwhile, the wide-body 135mm width version, with a maximum vertical load capacity of 100kg, can carry an entire deep-well plate stacker. In an automated library preparation workstation for next-generation sequencing (NGS), multiple high-low temperature linear modules work in concert, performing all actions from magnetic bead mixing and washing to elution. The key here is that after repeated operation at min -196°C, the straightness of the high-low temperature linear module does not degrade due to microscopic ice crystal formation on rail surfaces. The KLS Series High-Low Temperature Linear Module incorporates precision scrapers and anti-condensation airflow designs, maintaining ±0.01mm repeatability even under extreme humidity swings. For high-throughput qPCR systems used in pathogen detection, this high-low temperature linear module rapidly shuttles sample plates between different temperature zones, compressing overall reaction time. In summary, the KLS Series High-Low Temperature Linear Module is not merely a transmission component; it is a core enabler of sample integrity and high-throughput automation in biomedicine.
