Plant Growth Chamber ＜Standard model＞

Models L(P)H-241PFP/D/ST-S(P) and L(P)H-411PFP/D/ST-S(P) are standard plant growth chambers. There are two control modes available. One is a changeover mode, changing between constant operation and day/night switching operation. The other is a program control mode. Three-position controller is used for temperature and humidity control, which provides energy-saving effects. A wide variety of chambers are available in sizes ranging from 240 liters to 410 liters.

Features

  • An operation touch panel with time display is mounted on the upper part of the main body, which allows easy operation.
  • Model L(P)H-□PFP/D/ST-S allows both constant operation at any temperature/light/ (humidity) and day/night switching operation.
  • Model L(P)H-□PFP/D/ST-SP allows a program control.
  • Five-sided illumination. The light can be continuously dimmed form 20% to 100% or 0%.
  • Model LHs don’t need a drain hose or a tank because of a forced evaporation system inside the chamber.
  • Three-position controller is used for temperature and humidity control (proportional control for heating), which provides low running costs.
  • The inner door has energy-saving functions, being used as one door or two up-and-down doors as per usual.
  • Two-level wind speed control is installed to protect wind-sensitive plants..
  • A hole of 40 mm diameter for measurement is included as standard.
  • Humidity control system can be selected from “only humidification” or “only dehumidification” or “both humidification and dehumidification.”

Applications

  • Plant cell/tissue culture, germination, acclimation, or growth test
  • Environmental test
  • Growth of rice, arabidopsis, etc.
  • Insect experiment
  • Cell culture
  • Environmental resistance test for plants
  • Storage test at constant temperature and at constant humidity (only Model LPH)

Options

  • Table for a water tank (Model LPH), network observing system, MultiSpex PF-75T, metal halide lamp, carbon dioxide removal unit.
