Programmable Cooler, Embryo Freezer

Programmable Cooler, Embryo Freezer
  • Model : Programmable Cooler, Embryo Freezer
  • Brand :
  • Product ID :
  • Product Type : Industrial products series
  • Product Content :
Program control chiller(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.


Programmable Cooler, Embryo Freezer


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.

②Programming Functions:

Any number of user programs can be programmed. Computer control freezing process according to user programs. User programs can program,revise,store and tune out easily. Current user programs can be tuned out automatically when starting up.


③Run-time control function

Random constant temperature function: can in and remove a constant temperature at any time.

Manual function:Manual control can take part in control during program control , and it can also be controlled by manual completely.

Keying function:can change cooling rate with keyboard to make temperature control great flexible.

Coordinate transformation function: X-coordinate and y-coordinate can interconvert according to need.

Section into function: can skip current programs and go to next section at any time.


④Data Processing Function

All the data and related information of every freezing can form a data file and be stored down automatically.

Temperature data and rate can be listed according to specified time or displayed temperature curves.

The software can retrieve bidirectionally the stored date files quickly and conveniently.

Temperature curve can magnify at local to research the subtle change of  critical sections.
Sorry that some other functions can not list, if these functions can be used cooperatively, it can bring great convenience in freezing.
