Liquids dispenser MEDIAFILL 20M

culture mediaautomatedfoot-operated

Product overview MEDIAFILL 20M is an electronic peristaltic dispensing system for precise delivery of culture media and aqueous reagents in microbiology and clinical laboratories. It supports accurate metering and repetitive dispensing for applications such as pour‑plate preparation and test‑tube filling, and is designed for use in food, pharmaceutical, government testing and research laboratories.

Short description

• Flexible dispensing to tubes, flasks and Petri dishes with interchangeable tubing and anti‑drip head.
• Compact, portable design to save bench space.
• 3‑inch TFT resistive color touchscreen with 32‑bit ARM controller.
• Automatic foot‑switch recognition, timed filling and infrared sensing options.
• Innovative functions: flow intelligent calibration, quantitative correction, suction angle adjustable 1°–720°, buffer delay.
• Pop‑up pump head for quick replacement of dispensing tubing of different diameters.
• Sanitary anti‑drip dispensing head; fluid path limited to sterilizable tubing.

Instrument Features

• Portable peristaltic pump host with separated pump and tubing design to minimize contamination.
• Intuitive 3‑inch touchscreen interface controlled by a 32‑bit ARM MCU.
• Support for external controllers and foot switch for remote start/stop.
• Multiple dispensing modes including continuous, timed, quantitative, duplicate and weighing filling.
• Rapid tube change via pop‑up dispensing head; anti‑drip nozzle preserves reagent and maintains hygiene.
• Supplied with a set of dispensing tube diameters to cover a wide volume range while preserving accuracy.

Instrument technical parameters

• Programmable dispensing modes: ≥ 20.
• Dispensing accuracy: error ≤ ±1.0% under specified conditions.
• Maximum single dispense volume: 3000 mL.
• Dispensing flow rate range: 0.6 mL/min – 7000 mL/min.
• Sterilizable dispensing tube inner diameters (optional): 1.6 mm, 2.4 mm, 3.1 mm, 4.8 mm, 6.4 mm, 7.9 mm.
• Five working modes: continuous conveying, timed filling, quantitative filling, duplicate filling, weighing filling.
• On‑screen animation displays working status; parameters, flow data and configuration shown on one screen.
• Membrane keys for start/stop; external controller support for remote operation.
• Fluid only contacts sterilizable tubing; pump body remains separate to reduce contamination risk.

Instrument configuration

• Dispensing pump host: 1 set.
• Anti‑drip dispensing head: 1 set.
• Sterilizable dispensing tube set: 1 set (selectable inner diameters).
• Foot switch: 1 piece.
