Macrofriger BL Microprocessor-Controlled Centrifuge

Multipurpose centrifuge with all-metal construction, controlled by microprocessor. Brushless induction motor — no carbon brush maintenance, no unscheduled downtime. Capacity ranges from 1.5/2.2 ml vials to 250 ml tubes and 500 ml blood bags, making it suitable for haematology, biochemistry and blood bank work on a single instrument.

Construction and Safety

• Outer cabinet: Dur-Al alloy
• Bowl and counter-lid: Stainless steel
• Safety chamber: Steel, interposed between bowl and outer cabinet
• Noise level: 50–60 dBA
• Airflow: Channelled to rear outlet — limits temperature rise in the bowl with minimal back-pressure

Control and Electronics

Microprocessor-governed digital circuit. Controls speed, acceleration, braking, RCF, temperature and time. Stores up to 10 independent programmes. Integrated operational alarm system.

Rotor identification sensor: on closing the lid, the microprocessor automatically receives all operating limits for the installed rotor. Eliminates programming errors before the run starts. Open system — rotor range can be extended without manufacturer restrictions.

Accessory Identification

Rotors, buckets and adaptors identified by permanent laser engraving. No labels to wear off, no mix-ups when mounting the rotor.

Refrigerated Version

Hermetic compressor unit mounted on anti-vibration coupling. Evaporator surrounding the inner bowl for uniform cooling. Available in the refrigerated version of the instrument only.
