The user manual outlines a standard sequence for running clinical tests:
Startup & Self-Test: Upon powering on, the device performs an internal diagnostic check of the optical system and mechanical components.
Technique Selection: Users select a pre-programmed method (e.g., Glucose, Cholesterol, ALT/AST) from the menu.
Blanking: The system prompts the user to aspirate distilled water or a reagent blank to set the zero baseline. Calibration:
For quantitative tests, a standard or calibrator is aspirated to establish the factor.
Sample Measurement: The patient sample is aspirated through the sipper system. The then displays and prints the concentration. Measurement Modes The device supports several analytical modes: End-point: Fixed-time readings for stable reactions. biosystems bts 350 user manual
Kinetic: Continuous monitoring of absorbance change over time.
Differential: Comparison between two specific measurement points. Fixed Time: Measurement at a specific interval. Maintenance & Troubleshooting
To ensure accuracy, the manual recommends the following routine care:
Daily: Perform a wash cycle with distilled water at the end of each session to prevent protein buildup in the flow cell.
Weekly: Use a specific cleaning solution (like BioSystems' "Cleaning Solution") to decontaminate the tubing. Common Errors:
Low Signal: Often indicates a dirty flow cell or an obstructed optical path.
Aspiration Failure: Usually points to a leak in the peristaltic pump tubing or a blockage in the intake needle. Accessing the Full Manual

Guide to the BioSystems BTS-350: Operation and Maintenance The BioSystems BTS-350 is a staple in clinical laboratories worldwide. Known for its durability and "workhorse" reputation, this semi-automatic analyzer is designed to handle a wide range of clinical chemistry and turbulence assays.
Whether you are a laboratory technician setting up a new unit or a manager ensuring compliance, understanding the core components of the user manual is essential for accurate diagnostics. 1. System Overview and Technical Specifications
The BTS-350 features a high-performance optical system. Unlike many entry-level analyzers that use standard filters, the BTS-350 utilizes a LED configuration that covers the entire range of routine clinical chemistry. Light Source: LEDs (long-lasting, low heat generation). Wavelengths: 340, 405, 505, 535, 560, 600, 635, and 670 nm.
Thermostatic System: A Peltier effect controller maintains the flow cell at 25°C, 30°C, or 37°C.
Memory: Capable of storing up to 150 techniques and 2,000 results. 2. Initial Setup and Installation
Before running your first test, ensure the unit is placed on a level, vibration-free surface away from direct sunlight.
Powering On: Connect the unit to a stabilized power source. The BTS-350 performs an automatic self-check of the optical and mechanical systems.
Priming the System: Use distilled water to prime the aspiration system. This ensures no air bubbles are trapped in the flow cell, which is the most common cause of "noisy" readings.
Thermal Equilibrium: Allow the unit 10–15 minutes to reach the programmed temperature (usually 37°C for most enzymes). 3. Programming and Running Assays
The user interface is menu-driven. To program a new technique: Zeroing:
Select Calculation Mode: Choose from End Point, Kinetic, Fixed Time, or Differential.
Input Parameters: Enter the wavelength, aspiration volume, and factor (or standard concentration).
Calibration: Always run a fresh standard or calibrator when switching reagent lots. 4. Routine Maintenance (The "Golden Rules")
To keep your BTS-350 running for a decade or more, follow these maintenance steps:
Daily: Wash the flow cell with distilled water after every work session. Never leave reagents or serum sitting in the tubing overnight.
Weekly: Perform a deep clean using a specialized laboratory detergent (like BioSystems Bio-Set) to remove protein buildup.
Monthly: Check the aspiration volume. If the volume is inconsistent, inspect the peristaltic pump tubing for wear or "memory" flat spots. 5. Troubleshooting Common Error Codes
"Low Signal": Usually indicates a dirty flow cell or a failing LED. Try an intensive cleaning cycle first.
"Temperature Out of Range": The Peltier element may be struggling. Ensure the back of the machine has at least 10cm of clearance for airflow.
"Aspiration Error": Check for a blockage in the intake needle or a leak in the peristaltic pump tubing. Conclusion
The BioSystems BTS-350 remains a gold standard for semi-automatic analysis because of its reliability. By following the manual’s guidelines on flow cell hygiene and temperature stability, laboratories can ensure precision in every patient result.
The BioSystems BTS-350 is a semi-automatic clinical chemistry analyzer utilizing LED-powered optics for photometry and turbidimetry. Operation involves a menu-driven interface, including concentration measurements, programmed test parameters, and a required maintenance routine involving daily flow cell washing.
