Overview
For laboratories preparing culture media, sterile dispensing is critical to guarantee subsequent test performance and meet quality standards. Labs also seek cost savings and better performance, which requires stable workflows. These needs drive the demand for reliable media dispensing systems supporting unattended operation while complying with quality requirements. Our AMD series automated and HMD series semi-automated media dispensing systems are engineered for this purpose.
AMD280 Media Dispensing System is a laboratory instrument for filling petri dishes with agar nutrient media. It is standard for 90mm petri dishes, and other dish sizes can be customized.
Pain Points Solved
- Manual media dispensing: Uneven dosage, heavy workload, low efficiency and high contamination risk.
- Ready-to-use purchased media: High cost, short shelf life (max. 6 months), frequent reordering, strict storage and transport requirements (2–25°C, protected from light), and mandatory cold-chain logistics.
- Media dispensing system: Automatic dispensing, high throughput, reduced contamination sources, and removes limitations on bulk storage and transportation.
Automated AMD Series — Parameters & Features
- Consists of three modules: main control system, rotor system and carrousel.
- 5.7-inch touch screen with intelligent operating system for simple operation.
- Rotor and carrousel made of hard aluminum alloy, easy to disassemble.
- Two optional carrousels: 280-petri-dish type and 400-petri-dish type; customization supported.
- Peristaltic pump with automatic suck-back anti-spill design to prevent media dripping.
- Dispensing range: 1–1000 ml, precision <1%. Can dispense 280 petri dishes within 25 minutes.
- Fast volume calibration. Users can set and save multiple dispensing programs and call them as needed.
- UV protection for the dispensing area.
- Fault alarm and self-diagnosis function for quick fault detection and maintenance.
Semi-automated HMD Series — Parameters & Features
HMD series semi-automated media dispensers deliver culture media, agar, buffer and other liquids. Replacing manual pouring, they provide high precision to avoid inconsistent dosing, lower contamination risks and boost efficiency.
- Three dispensing modes: Continuous dispensing, single dispensing and multiple dispensing.
- Intuitive full-size graphical user interface for easy control; stores up to 30 dispensing programs.
- Equipped with foot pedal switch for hands-free operation.
- Compatible with petri dishes, test tubes and other lab containers.
- Built-in system calibration program to ensure accurate dispensing volume.
- Dispensing volume: 1–1000 ml, precision less than 1%.
