a support rod is arranged on the lower side surface of the sample rack, and the other end of the support rod is fixed at the bottom of the ice tray;
and the sample holder is provided with a through sample position.
Wherein, still be provided with the ice mouth of moisturizing that link up on the sample frame.
And the sample rack is also provided with a through temperature measuring port, and the thermometer is inserted into the ice-water mixture through the temperature measuring port.
Wherein, the lateral part of flourishing ice dish is provided with water level safety hole, and the lateral part of insulation cover is provided with the outlet valve.
Wherein, the bottom of the ice tray is provided with a positioning hole corresponding to the supporting rod.
Through the technical scheme, the utility model has the advantages of as follows:
1) the temperature monitored by the thermometer is visual;
2) the temperature of the insulating sleeve is controlled, ice can be added from the ice supplementing opening (a water outlet valve of the insulating sleeve needs to be opened during ice adding so as to discharge water overflowing from the water level safety hole in time), and the temperature can be controlled for a long time;
3) the sample rack is placed in the ice-water mixture, so that the sample rack is firmly attached, and the experimental operation is facilitated; placing the sample tube in a sample holder and immersing the sample tube in ice bath to really reach the ice bath temperature;
4) different sample holders are suitable for ice bath operation of sample plates and plate holders with various specifications.
