Program Freezer TF-PA

Program Freezer TF-PA
  • Model : Program Freezer TF-PA
  • Brand :
  • Product ID :
  • Product Type : Industrial products series
  • Product Content :
Program cryostat, also called program freezer (nicknamed programmable cooler) is adopted with microcomputer control technology and special software, so the amount of liquid nitrogen can be controlled accurately to ensure that cryopreserved biological products can cool and freeze at proper freezing rate. The instrument is easy to operate and the human-computer interface is clear.


Program Freezer TF-PA


    Clinical cryomedicine is developed rapidly in our country, so it stimulates the development of transplantation medicine and achieves remarkable success especially in bone marrow ,hemopoietic stem cell,skin,cornea, endocrine glands and cryopreservation and transplantation of blood vessel,valve,etc. Successful hematopoietic stem cell transplantation relies on the storage of hematopoietic stem cell activity. During the cooling and freezing process of biological samples , when a liquid is changing from a liquid to a solid state, a certain amount of heat is released to make temperature rise. If freezing process of cooling rate is not controlled, it will lead to the death of histocytes. In order to determine the phase transition point for biological samples accurately, programming cooling programs with microcomputer to increase the amount of liquid nitrogen input when the samples changes, overcome the temperature rising of phase change samples, ensure cells get through the phase transition safely and quickly, which is the key process to improve the survival rate of frozen samples.



1.Main technical indicators:

 Model:                                    TF-PA

 Temp Control Range:         40℃~-110℃

 Temp Accuracy:                    error within 0.5℃

 Cooling Rate:                        in the range from 0.1℃/min to 40℃/min

 Heating Rate:                        in the range from 0.1℃/min to 30℃/min


2. Instrument structure

The instrument is made up of following four parts.(standard configuration)

(1)Microcomputer System: inner freezing control card, just running related software when freezing.

(2)Freezer: The freezer is made of stainless steel structure inside and outside. Freezing volume is not smaller than 200*200*200mm. The freezer can contain 160 cryovials and 8 blood bags in the same time.

(3)Liquid Nitrogen Container And Liquid Nitrogen Pressurizer: Liquid nitrogen pressurizer is installed on the 30m³ liquid nitrogen container to realize the self-pressurization in the container and maintain the pressure stability of control valve.



微机系统: 内置冷冻控制插卡,冷冻时只要运行有关软件即可..

冷冻箱:  内外全不锈刚结构.冷冻容机不小于200*200*200毫米.可同时容纳冷冻管160个或血袋8个.

液氮罐及液氮加压器: 液氮加压器安装在30立升的液氮罐上,使罐内自增压,调节阀保持压力稳定.
