Recirculation Top Reactor Sampler

Extracts a liquid sample from reactors and vessels via a dip pipe and re-circulation loop.

  • Integrated pH / conductivity measurement.
  • Seed & slurry charging option.
  • Ideal for PAT applications – In-Situ & Extractive sampling.
  • Sample is representative.
  • Robust system for lower maintenance costs.

 

Operation & Cleaning

  • A tubular diaphragm pump is used to draw the sample up the dip pipe, around the re-circulation loop and return it to the vessel.
  • The liquid to be sampled is re-circulated for a few minutes to ensure a representative sample; pH measurement can take place at this point.
  • The sampling valve is either manually or pneumatically actuated to allow sample flow into a sampling bottle.
  • Straight-through pumps design allows a full nitrogen blow-through to clean and dry the system after every sample

Pump design

  • Handles viscous and abrasive products
  • Can run dry without damage
  • Capable of passing up to 6 mm diameter solids (up to 50% crystal concentration)
  • Self priming, up to 3m height

Integration of PAT Devices

  • Ideal Delivery Platform for PAT devices
  • probes are visible to operators through sightglass widnow
  • Extractive sample can be taken at point of measurement for ease of validation
  • ProSys ProTrac Retractable Assembly for ph Applications
  • Customised solutions available for non-standard PAT devices

Technical Features

  • Unique compact FlowCell allows sampling, in-line measurement and large sightglass with no dead space
  • Air operated tubular diaphragm pump.
  • Fully Teflon Lined re-circulation loop, sampling valve and solvent flush valve.
  • Borosilicate sample bottle – ISO GL 45 standard bottle connection (special threads available on request)
