Platypus Jar Tester

Operations and designer tools to assess the physical and chemical treatment of surface and ground waters.

Platypus 4G Jar Tester

Test Scope:

  • coagulants, polymers, alkalinity treatment
  • metals oxidation
  • settlement rates
  • pre-treatment for flotation tests
  • reaction kinetics
  • mixing and flocculation power evaluation
  • metal residuals

World Class Product

  • modern technology, functionality and presentation
  • relevant European, US and AS/NZ EMC test certification
  • advanced LED backlighting

Independent Mixing Stations

  • programmable speed and time settings for each of three flocculation stages - at each station

Advanced Backlighting

  • ice white backlighting to observe floc development, settling rates and supernatant clarity

Digitally controlled, easy to operate

  • LED speed, time, alarm and status displays
  • three programmable flocculation stages
  • independently programmable duration and speed for each flocculation stage
  • paddle speed is not inferred. Paddle speed settings are Hall Effect speed controlled to set point - notwithstanding commonly experienced water temperature variations/viscosity and paddle type and size
  • tactile membrane decals

Square Jars

  • durable, clear polycarbonate materials
  • injection moulded; easy to clean fillets at the Jar floor, walls and corners
  • anti-slip top lips for safe handling in wet environments
  • square jar geometry for emulation of plant conditions
  • 1L or 2L Jars with or without supernatant sample taps
1L Jar
2L Jar
2L Jar with sample tap

Velocity Gradient Tables:

  • Velocity gradient translation Tables provide bench test correlation of Jar mixing energy under variable water temperature, paddle type and size to determine optimum plant velocity gradient requirements
  • Better bench test emulation of plant flocculation conditions - facilitates accurate determination of optimum plant flocculation power

Safe Operation In Wet Environments:

  • low voltage internal power
  • splash proof membrane decals


  • low noise power transmission belts

Platypus Jar Tester Carry Case

  • Internal foam cradle protection
  • Internally recessed retractable handle
  • Twin core fluted PP walls
  • Heavy duty wheels

Clip-On Polycarbonate Paddles

  • small, large, butterfly radial and axial flow paddles
  • easy to clean
  • emulate plant flocculation conditions
  • select paddle to suit velocity gradients
