Product Introduction
When an infectious disease outbreak strikes, diagnostic laboratories face an impossible mandate: process thousands of specimens daily while maintaining zero false-positive contamination. A single contaminated extraction batch can trigger cascading false-positive results, unnecessary quarantines, and misallocated public health resources. The HM-TQ96 from HM Instruments was engineered for exactly this scenario — delivering 96-channel throughput with a three-layer contamination prevention system that makes it the reference standard for epidemic response laboratories worldwide.
The first contamination barrier — built-in UV disinfection — destroys residual nucleic acid molecules on instrument surfaces between extraction runs. The second layer — replaceable HEPA filtration — captures airborne particulates and aerosolized nucleic acids generated during high-volume specimen processing. The third layer — anti-pollution contact plates — physically prevents liquid splash transfer between adjacent wells on the 96-deep-well plate. Combined with magnetic rod sleeves that physically isolate rods from sample liquids, the HM-TQ96 achieves the contamination-free operation required when false positives have serious public health and economic consequences.
Beyond contamination prevention, the HM-TQ96 delivers the extraction precision needed for reliable surveillance data. Temperature uniformity of ≤0.6°C across all 96 positions ensures consistent lysis regardless of well position. CV below 3% enables quantitative viral load tracking across populations. Sensitivity exceeding 95% at 100 copies detects low-level infections during early-stage outbreaks. Explore cross-industry nucleic acid extraction applications for comprehensive deployment guidance.
Applications
- Epidemic surge testing: Rapid deployment during infectious disease outbreaks processing 500+ specimens daily
- National surveillance programs: Population-level pathogen monitoring for influenza, SARS-CoV-2, and emerging threats
- Blood safety screening: High-throughput nucleic acid testing of blood donations for HIV, HCV, HBV, and West Nile virus
- Wastewater epidemiology: Community-level pathogen detection through concentrated wastewater nucleic acid extraction

FAQ
Q1: How does the HM-TQ96 prevent false positives during epidemic testing?
False positives in epidemic testing typically result from nucleic acid contamination carried over from previous extraction batches. The HM-TQ96 employs four complementary barriers: UV disinfection destroys surface nucleic acids between runs; HEPA filtration removes airborne aerosols; anti-pollution contact plates prevent splash transfer between wells; and magnetic rod sleeves physically isolate rods from sample liquids. Together, these barriers reduce contamination risk to negligible levels even during continuous high-throughput operation processing thousands of specimens daily.
Q2: What is the daily processing capacity of a single HM-TQ96 unit?
Processing 96 samples per batch in 15–40 minutes, a single HM-TQ96 can complete approximately 10–16 batches during an 8-hour shift, yielding 960–1,536 extractions per day. During epidemic surges with extended operating hours and streamlined protocols, laboratories have reported processing over 2,000 specimens per day on a single instrument. Multiple HM-TQ96 units can be deployed in parallel for national-level response programs.
Q3: Can the HM-TQ96 be used for wastewater-based epidemiological surveillance?
Yes. Wastewater-based epidemiology requires extraction from concentrated wastewater samples that contain diverse microbial communities and chemical inhibitors. The HM-TQ96's open platform supports wastewater-optimized magnetic bead kits, and the 96-channel throughput enables processing of population-level surveillance panels efficiently. The 30–1000 μl volume range accommodates the concentrated wastewater aliquots typically used in community monitoring programs.
Q4: How quickly can the HM-TQ96 be deployed during a new outbreak?
The open reagent platform allows immediate use of any validated magnetic bead extraction kit — no waiting for proprietary reagent development. Pre-loaded epidemic response protocols can be activated within minutes, and new pathogen-specific protocols can be imported via USB from reference laboratories. HM Instruments' service network provides priority deployment with 4-hour arrival in capital cities. During the initial COVID-19 response, laboratories with existing HM-TQ96 units transitioned to SARS-CoV-2 testing within 24 hours of receiving validated extraction kits.
Q5: What certifications does the HM-TQ96 hold for clinical laboratory use?
HM Instruments holds ISO9001 quality management certification and multiple product-specific certifications verified on blockchain through Zhixin Chain for tamper-proof quality documentation. The HM-TQ96 complies with international safety standards for laboratory electrical equipment. For specific regulatory approvals in different markets, customers should contact HM Instruments' regulatory affairs team for market-specific certification documentation.
