Revolutionizing Hard Tissue Sample Preparation
The recovery of genetic material from skeletal remains is a cornerstone of forensic identification, yet the initial step of hard tissue processing has long been a manual, time-consuming, and contamination-prone bottleneck. The Automated Forensic Bone & Teeth Grinder represents a paradigm shift in DNA extraction preparation, transforming this critical phase into a rapid, standardized, and highly reliable automated process. Engineered specifically for the demands of forensic science, this instrument is designed to efficiently pulverize teeth and dense bone fragments into a fine, homogeneous powder, creating the optimal substrate for downstream DNA isolation. By automating this foundational step, laboratories can achieve greater consistency, higher throughput, and significantly improved DNA yields from their most challenging samples.
Core Advantages: Precision, Purity, and Proven Performance
The design philosophy of this instrument centers on delivering uncompromising results where it matters most: sample integrity and analyst safety. It replaces variable manual techniques with a standardized, automated grinding process that guarantees consistency from one sample to the next. Every engineering decision, from the sealed grinding chamber to the disposable grinding chamber consumables, is made to uphold the principles of contamination-free operation and high efficiency. This results in a system that not only protects the delicate DNA within the sample but also safeguards the laboratory environment and its personnel, establishing a new benchmark for reliable hard tissue processing.
Rapid & Efficient Processing: Complete Sample in 120-200 Seconds
Time-saving automation is a key benefit. The instrument completes a full grinding cycle, transforming a tooth or bone fragment into a fine powder, in approximately two to three minutes. This fast grinding capability stands in stark contrast to the lengthy and physically demanding process of manual crushing with a mortar and pestle or the inconsistent results from other mechanical mills. This high throughput directly translates to increased laboratory productivity, allowing analysts to prepare more samples for extraction in a single shift and accelerating the overall timeline for identification projects, from historical remains to active missing persons cases.
No Heat Generation: Preserves DNA Integrity During Pulverization
A critical concern during mechanical grinding is the generation of frictional heat, which can denature and fragment DNA, reducing both yield and quality. Our system employs an advanced cryogenic grinding mechanism that ensures a consistently low-temperature process throughout the operation. By effectively preventing heat buildup, the technology safeguards the DNA degradation prevention, preserving the length and integrity of the DNA strands. This is especially crucial for already degraded forensic samples, where every intact molecule counts, ensuring that the maximum amount of genetic information is preserved for subsequent STR amplification or next-generation sequencing.
Zero Cross-Contamination: 100% Single-Source DNA Recovery with Disposable Cassettes
The most significant risk in forensic sample processing is cross-contamination between cases. This system eliminates that risk through a revolutionary single-use design. Each sample is placed into its own dedicated, pre-sterilized disposable grinding cassette. This cassette is the only component that contacts the sample. After grinding, the entire cassette, now containing the powdered sample, is removed. The grinding chamber itself never comes into contact with biological material, making thorough cleaning between runs unnecessary and guaranteeing 100% single-source DNA recovery. This approach represents the gold standard in cross-contamination prevention for forensic genetics.
Sealed & Safe Operation: Closed System Eliminates Biohazard Exposure
Laboratory safety is paramount when processing potentially hazardous biological materials. The grinding process occurs entirely within a sealed, robust grinding chamber. This closed system design ensures that no powder aerosol or bone dust is released into the laboratory environment during operation. Analysts are protected from inhaling particulate matter, and the risk of contaminating other workspaces or evidence is nullified. This feature not only protects personnel but also upholds the stringent clean lab standards required for sensitive DNA analysis, making the instrument safe for use in open laboratory settings.
Intelligent Operation: 10-Inch Touchscreen, Barcode Scanner, and Data Export
The instrument is controlled via an intuitive 10-inch color touchscreen user interface, requiring minimal training. For seamless sample tracking and chain of custody, an integrated barcode scanner allows the technician to scan the sample ID directly from the cassette or associated paperwork at the start of the cycle. All process data, including sample ID, date, time, and cycle parameters, is logged. This data can be easily exported via USB or Ethernet connection to a laboratory information management system (LIMS) or external drive, providing a digital audit trail and simplifying laboratory record-keeping.
Reliable & Compliant: Bilingual Interface and Automatic Audit Trail (4000+ Records)
Designed for global forensic use, the system features a fully bilingual interface (Chinese/English) that can be switched with a single touch. Internally, the instrument maintains a robust, non-volatile memory capable of storing detailed audit logs for over 4000 grinding cycles. Each log entry includes a timestamp, user ID, sample ID, and cycle parameters.
Validated Performance: Official Ministry of Public Security Test Report
The performance and reliability of this system are not merely claimed; they are officially certified. The instrument has undergone rigorous independent testing by the Ministry of Public Security (MPS) in China, a leading authority in forensic science and technology. The official MPS Test Report provides forensic validation of the system's key metrics, including grinding efficiency, powder consistency, and its impact on downstream DNA yield. This official certification offers laboratories independent verification and confidence that the technology meets the exacting standards required for forensic casework and is a reliable tool for producing court-admissible results.
Independent Verification of Key Performance Metrics
The validation data within the test report provides a quantitative, side-by-side comparison of the automated system against traditional manual methods. Key performance metrics such as total processing time, particle size distribution of the resulting powder, and, most importantly, the comparative DNA yield from subsequent extractions are clearly documented. This data demonstrates that the automated process not only saves significant time but also consistently produces a finer, more homogeneous powder that leads to higher and more reproducible DNA recovery, especially from challenging, low-yield samples.
