Summary of CCL420 Fully‑Automatic Clinical Chemistry Analyzer (600 Tests/hour, with Refrigeration Function)

Product Overview

CCL420 is a high‑performance fully‑automatic biochemical analyzer oriented for mid‑level medical‑care institutions. It features maintenance‑free optical‑detection, solid‑state constant‑temperature, self‑pressure‑releasing liquid‑circuit and enhanced anti‑cross‑contamination cleaning technologies, delivering high reliability and good cost‑performance.

Core Performance

‑ Throughput: 450 tests/hour, maximum up to 600 tests/hour.
‑ Assay methods: End‑point, kinetic, two‑point method; supports unlimited add‑on tests and emergency‑sample priority.
‑ Running modes: continuous measurement, random selection, emergency‑sample insertion.
‑ Cleaning: Automatic 9‑stage / 21‑step cleaning with acid‑alkali detergent; optional warm‑water cleaning; water consumption＜15 L/hour. High‑/low‑concentration waste liquid is discharged separately for environmental protection.

Key Technical Modules

1. Optical System
   ‑ Spot‑fiber‑transmission, fully‑sealed maintenance‑free photoelectric detection system; each monochromatic light uses independent photoelectric converter.
   ‑ Light‑source: 12 V halogen‑tungsten lamp (lifespan＞2000 hours, automatic light‑intensity detection).
   ‑ Wavelength range: 340 nm‑800 nm, 8 standard wavelengths, expandable.
   ‑ Absorbance linear range: 0‑4.0 A; resolution: 0.0001 A.
2. Constant‑Temperature Reaction System
   ‑ Solid‑state constant‑temperature heating; metal‑embedded heating design with only 1 mm air gap. Combined with adaptive PID algorithm, temperature‑control accuracy reaches 37 ± 0.1 ℃, fast and uniform heating, free from ambient interference.
   ‑ 135 reusable semi‑permanent UV‑transparent cuvettes; quartz cuvettes optional.
   ‑ Minimum reaction volume: 140 μL to save reagent consumption.
3. Sample & Reagent System
   ‑ Sample tray: 12‑8 sample positions, expandable; sample volume: 2‑40 μL (0.1 μL increment). Compatible with blood‑collection tubes and micro‑cups.
   ‑ Three independent nano‑polished sample probes with liquid‑level sensing, volume‑tracking and full‑range anti‑collision functions.
   ‑ Reagent tray: separate R1/R2 refrigerated trays, total 100 reagent positions (expandable). Semiconductor refrigeration keeps temperature 2‑8 ℃ for 24‑h maintenance‑free reagent storage.
   ‑ Reagent volume: 20‑400 μL (1 μL increment). Supports original and third‑party reagent bottles.
   ‑ Independent double‑paddle nano‑polished stirrer, no liquid hanging.
4. Liquid‑circuit & Mechanical Design
   ‑ Pressure‑self‑releasing liquid‑circuit protects pumps & valves; two‑stage filtration blocks fine particles from poor‑quality source water.
   ‑ High‑precision low‑noise belt‑driven transmission mechanism. Whole unit is dust‑proof, moisture‑proof and ultra‑quiet.
5. Calibration & Quality‑Control
   ‑ Multiple calibration modes: single‑ / multi‑point linear, Logit, Spline.
   ‑ Real‑time, intra‑day and inter‑day QC; supports L‑J, Cumulative, Twin‑Plot charts. Westgard multi‑rules by default; QC rules are user‑customizable.
6. Software & Interconnection
   ‑ Windows operating‑system; Chinese / English user‑interface.
   ‑ Automatic data storage & backup; customizable print formats.
   ‑ Real‑time reaction‑process monitoring; seamless connection with LIS / HIS hospital information‑systems.
