High quality and excellent temperature stability, in a value-for-money package designed to meet the needs of the world`s researchers. The SUB Aqua Plus range is composed of eight models (2L, 2L shallow bath, 5L, 12L, 18L, 26L, 34L and dual baths).


  • Ambient +5ºC to 99ºC operation , Excellent temperature stability of +0.2ºC.
  • Drain tap included in SUB Aqua 12 Plus, 18 Plus, 26 Plus and 34 Plus models.
  • Dual 5L & 12L bath with dual controls for separate setups and temperature displays, optimum use of space, and value for money.
  • Small volume, shallow SUB Aqua 2S Plus microtube water bath ideal for life science applications, Three programmable temperature presets - allows commonly used temperatures to be quickly selected.
  • Front panel lock-out - disables front panel controls and prevents settings being accidentally changed
  • Countdown timer with audible buzzer - for accurate reaction timing.
  • Fixed thermal cut-out - protects the user if the bath is accidentally run without water or in the very unlikely event of failure of both control systems.
  • User settable, over-temperature sample protection - protects samples from over-heating.
  • Digital PID control for quick heat-up and precision control throughout the temperature range.
  • Clear, wide-angle viewing digital LED display with indication of heating state - 'heating-up', 'cooling down' or 'maintaining temperature'
  • Heater mat and sensor bonded to underside of tank - optimizes temperature uniformity, workspace and it is easy to clean.
  • Simple and intuitive programming - immediate temperature re-setting from -/+ buttons, Grant non-drip polycarbonate lid, included as standard - improves performance, limits evaporation and conserves energy.
  • Stainless steel tank - high grade steel with durable polished finish.
  • Clean, painted steel case - maximum chemical and abrasion resistance.
  • Grant polycarbonate perforated base tray, included as standard - promotes heat convection and optimal temperature uniformity and allows any container to be placed directly in the bath.
