Request a QuoteProduct Introduction
The HD-S600 Microbial Automatic Dispensing Instrument is designed for accurate measurement and automatic dispensing of reagent solutions with different densities in microbiology laboratories. It can be used for dispensing culture media, buffer solutions, diluents, and other laboratory liquids.
This instrument is suitable for multiple microbiological preparation workflows, including plate preparation, test tube dispensing, and MPN method tube dispensing. With precise volume control, multiple dispensing modes, programmable settings, and sterilizable dispensing tubing, the HD-S600 helps laboratories improve dispensing efficiency, reduce manual errors, and maintain stable liquid handling performance.
It is widely used in microbiology testing laboratories, food safety laboratories, pharmaceutical microbiology laboratories, environmental testing laboratories, research institutions, and quality control departments.
Working Principle
The HD-S600 uses a built-in microcomputer control system and a brushless DC motor to drive liquid dispensing. The motor operates smoothly and accurately, providing stable liquid flow without obvious vibration.
During operation, the user can set dispensing volume, dispensing speed, dispensing time, number of dispensing cycles, interval time, and back-suction angle through the touch screen. The instrument then automatically completes liquid transfer and dispensing according to the selected program.
Because the reagent only passes through the sterilizable dispensing tube, the system helps reduce contamination risks during microbiological liquid dispensing.

System Features
Accurate Liquid Dispensing
The HD-S600 provides a dispensing volume range from 0.01 ml to 9999.99 ml, with dispensing error less than ±0.2%. This makes it suitable for microbiology workflows that require repeatable and accurate liquid distribution.
Fast Dispensing Performance
The instrument supports fast dispensing with a maximum dispensing speed of 2000 ml/min. For a 20 ml test tube, the fastest dispensing time can be less than 1 second, helping laboratories improve sample preparation efficiency.
Three Dispensing Modes
The system includes three dispensing modes:
- Flow mode
- Dispensing mode
- Scheduled mode
These modes allow users to select suitable dispensing methods according to different laboratory scenarios.
Multiple Working Methods
The HD-S600 supports several working methods, including:
- Single dispensing
- Continuous dispensing
- Interval dispensing
- Scheduled dispensing
This flexibility makes the instrument suitable for plate preparation, tube filling, repeated reagent dispensing, and batch liquid handling.
Large Touch Screen Operation
The instrument uses a ≥4.2-inch industrial-grade true color LCD touch screen. Operators can easily set parameters, select programs, and monitor the dispensing process through the intuitive interface.
Programmable Dispensing Parameters
Users can program key parameters according to actual laboratory requirements, including:
- Single dispensing volume
- Dispensing speed
- Dispensing time
- Number of dispensing cycles
- Interval time
- Back-suction angle
This helps improve workflow consistency and reduces repeated manual adjustment.
Program Storage Function
Each dispensing mode can store 15 groups of dispensing programs. The instrument can store 45 or more programs in total. After startup, users can directly call saved programs, allowing faster preparation for routine laboratory work.
Sterilizable Dispensing Tubing
The dispensing tubes can be sterilized under high temperature and high pressure. Since the reagent only passes through the sterilizable tubing, the risk of cross-contamination is reduced.
Multiple Tube Diameter Options
The instrument supports six optional dispensing tube inner diameters:
| Tube Inner Diameter |
|---|
| 1.6 mm |
| 2.4 mm |
| 3.1 mm |
| 4.8 mm |
| 6.4 mm |
| 7.9 mm |
Different tube sizes can be selected according to liquid viscosity, dispensing volume, and workflow requirements.
External Control Capability
The HD-S600 supports RS485 communication using the Modbus protocol. It also supports multiple input interfaces, including 0–5 V, 0–10 V, 4–20 mA, and 0–10 kHz, making it suitable for integration with automated laboratory systems or production workflows.
