Herxi H/T85MM Benchtop Low-Speed Centrifuge for Food Safety Testing

Overview

The Herxi H/T85MM is a benchtop low-speed centrifuge engineered specifically for food safety laboratories requiring reliable, repeatable separation of heterogeneous samples under Good Laboratory Practice (GLP) conditions. It operates on the principle of sedimentation-based separation—utilizing controlled rotational force (RCF) to accelerate phase partitioning in suspensions, emulsions, and particulate-laden matrices such as milk, juice, meat homogenates, grain extracts, and environmental swab eluates. With a maximum speed of 8500 rpm and an RCF of 7500 ×g, it delivers sufficient g-force for pelleting cellular debris, precipitating proteins, clarifying turbid food extracts, and isolating microorganisms without shearing sensitive analytes—making it ideal for pre-analytical sample preparation prior to ELISA, PCR, HPLC, or microbial culture workflows.

Key Features

• Brushless DC motor with high-torque output and integrated thermal management ensures stable rotational performance across extended run cycles, with noise levels maintained at ≤60 dB(A) for low-disturbance lab environments.
• Dual-mode user interface featuring a 4.3-inch TFT-LCD color display with both touch-sensitive and physical keypad inputs; supports real-time simultaneous display of setpoints (speed, time, RCF) and actual running parameters.
• Comprehensive safety architecture includes triple-stage damping system, imbalance detection with automatic rotor stop, overspeed/overtemperature/undervoltage/overvoltage alerts, and electro-mechanical door interlock with silent latching mechanism.
• Biocontainment-compliant angular rotor (6 × 50 mL) equipped with integrated silicone elastomer sealing ring (RoHS 2015/863 compliant), minimizing aerosol generation during high-speed deceleration and ensuring operator and environmental protection.
• Wide-input voltage design (100–230 V AC, 50/60 Hz) enables consistent operation across diverse field deployment scenarios—including mobile food safety inspection vehicles—and eliminates need for external voltage regulators.
• Corrosion-resistant 304 stainless-steel centrifuge chamber, powder-coated steel housing, reinforced front panel, and triple-layer rotor protection sleeve collectively meet IEC 61010-2-020 requirements for laboratory centrifuge safety.

Sample Compatibility & Compliance

The H/T85MM accommodates standard conical-bottom tubes (2 mL, 5 mL, 10 mL, 15 mL, and 50 mL) and is validated for use with common food matrix-derived samples including dairy whey, fruit pulp supernatants, cereal starch slurries, seafood tissue homogenates, and surface rinse solutions. Its angular rotor configuration provides rapid sedimentation kinetics suitable for particulate removal prior to pathogen enrichment or toxin extraction. The unit complies with ISO 9001:2015 (quality management systems) and ISO 13485:2016 (medical device-related quality systems), reflecting adherence to documented manufacturing controls and traceability protocols. While not FDA 510(k)-cleared as a medical device, its design aligns with analytical instrument qualification (AIQ) expectations for regulated food testing labs operating under USDA-FSIS, EU Regulation (EC) No 852/2004, or China’s GB 4789 series microbiological standards.

Software & Data Management

Though hardware-controlled (no embedded PC or network interface), the H/T85MM supports audit-ready operation through persistent parameter logging: all executed runs—including start/stop timestamps, selected program ID, final RCF, elapsed time, and fault codes—are retained in non-volatile memory for up to 200 cycles. User-defined programs (20 stored slots) include configurable acceleration/deceleration profiles (10-step ramping), enabling method standardization across shifts or sites. The interface supports English, Chinese, Russian, and Portuguese language overlays—facilitating multilingual team deployment. All operational data can be manually transcribed into LIMS or ELN platforms, satisfying basic GLP record-keeping requirements per 21 CFR Part 11 Annex A guidance for non-electronic records.

Applications

• Routine clarification of food homogenates prior to immunoassay or nucleic acid isolation
• Sedimentation of suspended solids from beverage samples for turbidity or contaminant analysis
• Concentration of bacterial cells from enrichment broths in Salmonella or Listeria screening workflows
• Separation of fat globules from raw milk for compositional profiling
• Preparative pelleting of yeast or mold spores from environmental air or surface samples
• Field-deployable centrifugation in mobile food safety laboratories (e.g., roadside inspection units, port-of-entry testing vans)
