Constant flow sampler

Constant flow sampler

An automatic sampler specifically designed for samples that need to be analyzed for PFAS.

Manual grab sampling often carries a risk of PFAS contamination from the person or equipment involved. This risk is eliminated with the Constant Flow Sampler, which uses vacuum technology to draw the sample into a collection bottle. Only PFAS-free and approved materials (tubing and bottles) come into contact with the water sample.

Precise Volume Control:

The sample bottle is placed on a scale that ensures the vacuum is automatically adjusted to maintain the desired constant flow. Sampling stops automatically when the desired sample volume is reached.

Practical Design:

The sampler is housed in a durable, waterproof case, making it easy to transport and use in various environments.

Remote Control and Monitoring:

The device can be remotely controlled and monitored, and various alarms can be set up. The sampler can also be easily started remotely, ensuring sampling begins at the desired time.

Online Cloud:

Below is an example from our CLOUD platform. At the beginning, you can see how the vacuum is automatically adjusted to achieve the desired flow. The blue graph (LOAD) shows how the bottle fills up until 1600 ml is collected, at which point sampling stops automatically.

Available in Two Versions:

The Constant Flow Sampler is available in two configurations:

  • A battery-powered version with 18V DC for flexible, portable use.
  • A mains-powered version with 230V AC for continuous operation.
