Overview
The Tianyan TY-SuperVario-N is a precision-engineered Gerber centrifuge designed exclusively for standardized fat determination in dairy products. It operates on the principle of differential sedimentation under controlled centrifugal force and thermal stabilization—key requirements defined in internationally recognized methods including ISO 1211 (Gerber method), ISO 8587 (Babcock method), ISO 1735 (Mojonnier method), and IDF/ISO 8589 (solubility index for milk powder). Unlike general-purpose centrifuges, the TY-SuperVario-N integrates regulated heating (up to 68 °C) directly within the rotor chamber to maintain sample temperature above 50 °C throughout centrifugation—ensuring complete fat phase mobilization and minimizing interfacial emulsion formation. This thermally stabilized separation process significantly improves repeatability and reduces pre-centrifugation water-bath dependency, aligning with GLP-compliant laboratory workflows.
Key Features
- Triple-rotor compatibility supporting Gerber, Babcock, Mojonnier, and solubility index tubes (including standard 10 mL, 18 mL, and 50 mL formats)
- Programmable speed control (600–1130 rpm) with ±5 rpm accuracy, enabling precise adherence to method-specific g-force requirements
- Integrated Peltier-assisted heating system maintaining chamber temperature between ambient and 68 °C with ±0.5 °C stability over full runtime
- Automatic imbalance detection and immediate rotor deceleration (<1.5 s stop time) upon tube fracture or load asymmetry exceeding 5 g deviation
- Acoustic-dampened drive assembly and vibration-isolated base yielding operational noise <52 dB(A) at 1 m distance
- Interlocked safety lid with dual-mechanical latch and Hall-effect position verification—rotor cannot accelerate unless fully engaged and sealed
Sample Compatibility & Compliance
The TY-SuperVario-N accommodates all major standardized乳脂 tubes used in official dairy testing, including DIN 10778 Gerber flasks, AOAC 921.01 Babcock bottles, and IDF-standard Mojonnier extraction vessels. Its mechanical design conforms to IEC 61010-1:2010 for laboratory equipment safety, and thermal performance meets EN 61000-6-3 emission limits for industrial environments. While not certified to FDA 21 CFR Part 11 out-of-the-box, its parameter logging capability (via optional RS232/USB interface) supports audit-ready data capture when integrated into validated LIMS environments compliant with ISO/IEC 17025:2017 clause 7.7 (result reporting) and ISO 22000:2018 clause 8.4.2 (control of monitoring and measuring resources).
Software & Data Management
The TY-SuperVario-N operates via an embedded microcontroller-based interface with non-volatile memory storing up to 99 user-defined protocols. Each protocol retains independent settings for speed, duration, and target temperature—with timestamped execution history retained for the last 500 runs. Optional PC connectivity (via TTL-to-USB adapter) enables export of run logs in CSV format, including start/stop timestamps, actual vs. setpoint temperature profiles, and rotor RPM variance traces. When deployed in regulated facilities, these logs satisfy traceability requirements under EU Regulation (EC) No 852/2004 Annex II Section II (monitoring of critical control points) and support internal QA audits per ISO 9001:2015 clause 8.5.2.
Applications
- Routine fat quantification in raw milk, pasteurized milk, UHT milk, and recombined milk according to ISO 1211
- Fat recovery validation in whey processing streams using modified Gerber protocols
- Quality control of infant formula powders via solubility index-based fat extraction (IDF Standard 8589)
- Verification of fat homogenization efficiency in flavored dairy beverages through comparative centrifugal separation
- Method transfer studies between reference laboratories performing inter-laboratory proficiency testing (e.g., ILAC G13:2021)
FAQ
Does the TY-SuperVario-N meet ISO 1211:2022 requirements for Gerber fat testing?
Yes—the instrument delivers the specified 50–60 °C thermal environment and 900–1100 rpm rotational range required for Gerber method compliance, with documented thermal uniformity across the rotor cavity per ISO/IEC 17025 calibration guidelines.
Can it be used for Babcock testing of cream or condensed milk?
Yes—its programmable speed and temperature profile support AOAC 921.01 and ISO 8587 procedures, including extended centrifugation cycles (up to 60 minutes) and elevated temperature ramping for viscous samples.
Is routine calibration required, and what standards apply?
Annual speed and temperature calibration using NIST-traceable tachometers and RTD probes is recommended; calibration certificates should reference ISO/IEC 17025-accredited providers with scope covering centrifugal force and thermal chamber validation.
What maintenance intervals are advised for sustained accuracy?
Rotor inspection every 500 operating hours, bearing lubrication every 2,000 hours, and full gasket replacement every 3 years—or after 10,000 centrifugation cycles—per manufacturer’s service manual revision 3.2 (2023).
