Broadley James Corporation Flow Controller S/601 Flow Controller

• Used in bioreactors and fermenters to maintain precise gas flow for cell growth.
• Applied in laboratory settings for controlled delivery of gases in analytical processes.
• Integrated into pilot-scale bioprocessing systems for process optimisation and scale-up studies.
• Utilised in pharmaceutical research and development for controlled atmospheric environments.

Typical flow rate range

Units of this type commonly handle flow rates from a few millilitres per minute up to several litres per minute, depending on the specific model and application.

Control accuracy

Precision gas flow controllers typically offer high accuracy, often within ±1% of full scale, for stable process conditions.

Power supply

For this class of equipment, a standard laboratory power supply, commonly 24V DC or 100-240V AC, is typically required.

Interface

Units commonly feature a digital display and push-button controls, with options for remote control via analogue or digital communication protocols (e.g., RS-232, Ethernet).

Materials of construction

Wetted parts are typically made from inert materials such as stainless steel or PTFE to ensure compatibility with various gases and minimise contamination.

Operating pressure

Designed to operate within typical laboratory and bioprocessing pressure ranges, often up to 10 bar (150 psi).

• What type of gases can this controller handle?

  These controllers are generally designed for a wide range of non-corrosive and inert gases commonly used in bioprocessing, such as air, oxygen, nitrogen, and carbon dioxide. Buyers should confirm compatibility with specific process gases.

• Is this unit suitable for sterile applications?

• Does it require calibration?

• Can this controller be integrated into a larger control system?

• What maintenance does a unit like this typically require?

Pneumatic units for liquid handling are valued for their reliability, safety in sterile environments, and low maintenance demands. Buyers typically prioritize checking for air leaks, hose condition, and valve responsiveness when purchasing used equipment. Industry feedback highlights their durability and cost effectiveness compared to electric alternatives. Key considerations include compatibility with existing systems, calibration history, and whether regulators remain accurate. These units perform consistently across laboratory and pharmaceutical applications when properly maintained.
