BOC Carbon Dioxide Regulator Multi Stage 4 Bar – Series 8500 CO₂ Regulator (BS EN ISO 2503)

The BOC Carbon Dioxide Regulator Multi Stage 4 Bar (Series 8500) is a precision-engineered CO₂ regulator designed for sensitive laboratory, industrial, and research applications. Offering continuous, accurate, and stable gas flow, it is ideal for incubation, autoclaving, and freezer back-up systems where reliability and pressure consistency are essential.

This multi-stage carbon dioxide regulator maintains a constant outlet pressure even as cylinder pressure drops, ensuring smooth and controlled gas delivery. Manufactured to BS EN ISO 2503 and fitted with gauges conforming to BS EN ISO 5171, it meets the highest safety and performance standards required for professional gas control systems.

The robust brass body, precision components, and clearly marked dual gauges make the regulator easy to operate, providing accurate readings for both cylinder and outlet pressures. Its multi-stage design guarantees consistent performance across long periods of use, making it suitable for critical applications.
