is part of BioSystems' line of photometers, featuring an advanced optical system and a high-resolution color screen. It is optimized for small to medium-sized laboratories requiring reliable, semi-automated testing. Core Specifications
Light Source: Halogen lamp (6V, 10W) with an extended lifespan.
Wavelengths: 8-position filter wheel (340, 405, 505, 535, 560, 600, 635, and 670 nm).
Thermostat System: Peltier system (25°C, 30°C, 37°C, and room temperature).
Measurement Range: 0.0 to 3.5 Absorbance (A) for all wavelengths.
Memory: Storage for up to 150 techniques and 2,000 patient results. Operational Procedures
Start-up: Turn on the instrument and allow it to perform the internal self-test. The lamp and optical system are checked automatically during this phase.
Calibration: Use specific BioSystems calibrators. Select the desired technique from the menu and perform a "Water Blank" or "Reagent Blank" as prompted.
Aspiration: The instrument uses a peristaltic pump. Ensure the aspiration tube is clean and not kinked before drawing the sample/reagent mixture.
Reading: Results are displayed on the LCD screen and can be printed via the internal thermal printer or exported to a PC. Routine Maintenance
To ensure accuracy and longevity, follow these maintenance steps:
Daily: Perform a wash cycle with distilled water at the beginning and end of each shift to prevent protein buildup in the flow cell.
Weekly: Use a specialized cleaning solution (like BioSystems Bio-Wash) to deep-clean the hydraulic system.
Monthly: Inspect the peristaltic pump tubing for signs of wear or loss of elasticity; replace if necessary. Safety and Handling Use this guide alongside the full user manual
Waste Management: Treat all samples and waste containers as potentially infectious biohazards.
Power Supply: Use a stabilized power source to prevent voltage fluctuations from affecting the sensitive optical components.
For detailed troubleshooting or specific programming for BioSystems reagents, you can access the BioSystems Official Documentation or contact their technical support.
BioSystems BTS-350 is a semi-automatic chemistry analyzer that uses advanced LED optical technology for clinical diagnostics. The user manual provides instructions for operating the instrument, including maintenance of its flow cell and programming of various analytical techniques. Medical EXPO Core Manual Content & Operations Startup & Main Menu
: The analyzer features a menu-driven interface accessible via a tactile membrane keyboard or touch screen, depending on the specific model version. Key menu options typically include Concentration, Absorbance, Utilities, Configuration, and Programming. Aspiration & Fluidics
: It uses a continuous flow system with an integrated peristaltic pump. Sipping volumes can be programmed from Reading Modes
: The analyzer supports several measurement methods, including: Fixed Time Differential Mode Quality Control (QC)
