Peristaltic sampler
Reliable and precise sampling with a peristaltic sampler
A peristaltic sampler is widely used for automated water and wastewater sampling where precision, flexibility and sample integrity are essential. By using a peristaltic pump, the sampled liquid only comes into contact with the tubing, reducing contamination risks and ensuring consistent sample collection.
TEC42 develops advanced sampling solutions for industrial and municipal wastewater applications. Our expertise in automated sampling technology enables organizations to collect accurate and representative samples while minimizing maintenance and operational costs.
What is a peristaltic sampler?
A peristaltic sampler uses a rotating mechanism that compresses flexible tubing to move liquid through the system. Because the liquid remains inside the tubing, the sampling process is highly hygienic and suitable for a wide range of monitoring applications. Peristaltic samplers are commonly used for:
- Wastewater monitoring
- Industrial process control
- Environmental sampling
- Effluent monitoring
- Water quality testing
- Laboratory sample collection
A point to consider is that the suction tube requires regular replacement. For high interval sampling, vacuum technology is often better suited.
How does peristaltic sampling work?
The principle behind a peristaltic sampler is relatively simple. Rollers rotate over flexible tubing, creating a vacuum that draws liquid into the system and transports it to the sample container. This method offers several advantages:
- Gentle sample transport
- Bigger sample volumes taken at one time
- Minimal contamination risk
- Self-priming operation
- Suitable for intermittent sampling
Because the sample remains enclosed within the tubing, cleaning requirements can often be reduced.
Benefits and applications
Automated wastewater monitoring requires reliable equipment capable of operating continuously and consistently. Key benefits of a peristaltic sampler include:
- Low risk of cross-contamination
- Flexible installation options
- Reliable operation
- Easy maintenance
- Suitable for automated monitoring systems
Peristaltic samplers are frequently used in industrial wastewater treatment plants, municipal wastewater systems, environmental monitoring stations, food and beverage industries, chemical production facilities and research and laboratory environments.
