In September 2020, the Dongying Public Security Bureau procured our company's Chuangxing Model HD19-MN Hair Grinder and colloidal gold reagents. Our company dispatched technical personnel to deliver professional training to the relevant police officers of the bureau, helping them quickly master the operation of the hair grinder and reagents. Upon the completion of the training, the police officers conducted practical tests on hair samples from drug abusers and obtained accurate results.
Product Applications 1. High throughput with superior grinding performance: It efficiently and rapidly grinds 2×24, 2×48 and 4×96 samples, saving time and labor with minimal inter-batch and intra-batch variations.
2. No cross-contamination: Sample tubes remain fully sealed during disruption. Disposable centrifuge tubes and grinding beads are applicable, and samples are completely retained in the tubes to prevent cross-contamination between samples and external contamination.
Easy operation: Equipped with a built-in program controller for setting parameters such as grinding time and rotor vibration frequency, featuring a user-friendly interface.
3. Excellent stability: Adopts vertical oscillation for more thorough grinding and higher stability. The operating noise is less than 55dB, causing no interference to other experiments or instruments.
4. Convenient low-temperature operation: For low-temperature grinding requirements, the sample-loaded adapter can be immersed in liquid nitrogen for cooling for 1-2 minutes. After removal, it is quickly fixed to the host to start grinding immediately without re-freezing, thus saving liquid nitrogen.
5. High repeatability: Consistent grinding results are achieved for the same tissue sample with the same program settings. The short processing time prevents sample temperature rise.
Key Features 1. Innovative working mode: Integrates an innovative anti-vibration principle and 3D motion with vertical and horizontal shaking, creating an optimized grinding bead movement trajectory to ensure ideal sample processing and instant pulverization.
2. High-throughput processing: Capable of grinding up to 64 samples within 3 minutes, compatible with 12-position and 24-position liquid nitrogen freezing adapters.
3. LCD display for intuitive and easy operation, upgradeable to touch screen display and control.
4. Upgradeable cooling system: Support upgrade to ultra-low temperature cooling via liquid nitrogen or air chiller.
5. Safe and reliable operation: Equipped with a fastening device with automatic central positioning, an operational safety lock and full-process protection functions.
