Highly efficient bi-directional temperature gradient system for investigating responses to temperature shifts of seeds, small plants, insects, micro-organisms or any small component or material.

  • Temperature range (cold edges): +5 to 30 °C, (hot edges): ambient +5 to 45 °C, stability ±0,5 °C
  • Integrated multi-channel Squirrel data logger for recording time and temperature from five probes positioned underneath the plate – one in each corner and one in the centre – for post-cycle analyses on a PC
  • An adjustable timer controls the length of the two phases within the 24 hour cycle which automatically switches the gradient direction as programmed
  • Over temperature protection is provided on each edge by fixed temperature cut-outs

The design is based on the fact that a temperature gradient results if one edge of a square aluminium plate is heated and the opposite edge is cooled. The gradient runs in one direction for part of the 24 hour cycle and can then be automatically switched to run at a right angle to its original direction for the remainder of the cycle, to provide all possible combinations of minimum and maximum temperatures.

The unit is fitted with wheels for easy manoeuvrability. The removable Perspex grid effectively divides the working area into 196 miniature incubators, each with a different temperature regime – allows many samples to be tested without the need for separate controlled environment chambers.

An adjustable timer controls the length of the two phases within the 24 hour cycle which automatically switches the gradient direction as programmed GRD1 temperature gradient plate shown with integrated Squirrel data logger and optional hinged lid. Ideal for applications including overcoming seed dormancy, seed germination at constant or alternating temperatures and germination rates.
