英国Grant温度梯度培养箱/GRD1种子孵化箱

GRD1GX的双向温度梯度系统，可进行多向的温度循环：系统可以在24小时内先进行确定方向的温度梯度摸索，之后将梯度方向在铝板平面旋转90度，并依次选环并ZZ回到原位。从而得出实验样品在ZG温与ZD温的之间的正交数据。

GRD1温度梯度培养箱由英国瑞丁大学农业学院的Murdoch教授,和Roberts教授的初始设计，改进而来。

用于便捷取得种子、小型动植物、微生物、以及各种小型组分或材料，在不同温度下的反馈结果。

原理为在铝板平面一侧加热，同时另一侧制冷，从而在板面形成温度梯度。

• Robust, fully integrated system. Fitted with castors to assist with locating the unit
• A 24-hour adjustable timer controls the length of the two phases within the 24 hour cycle, and the switching of the gradient direction.
• A 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.
• Optional 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 later analysis by PC.
