Method and apparatus for freezing of a biological material
First Claim
1. A device for freezing biological material, comprising:
- a cooling unit;
a heat insulation unit, having an interface with said cooling unit and a common longitudinal axis passing through said interface transversely thereto;
an elongated slot disposed at least in said heat insulation unit and extending along said axis, said slot comprising a first slot portion remote from said interface and a second slot portion adjacent said interface;
wherein said first and second slot portions have respective first and second dimensions measured perpendicularly to said slot'"'"'s axis, the former being greater than the latter.

Abstract
The present invention provides a device for freezing biological material, comprising: a cooling unit; a heat insulation unit, having an interface with said cooling unit and a common longitudinal axis passing through said interface transversely thereto; an elongated slot disposed at least in said heat insulation unit and extending along said axis, said slot comprising a first slot portion remote from said interface and a second slot portion adjacent said interface; wherein said first and second slot portions have respective first and second dimensions measured perpendicularly to said slot'"'"'s axis, the former being greater than the latter.
Further provided is a container for accommodating therein of a biological material, said container having a longitudinal container axis and comprising a first container portion having a first dimension and a second container portion having a second dimension smaller than the first dimension, both measured perpendicularly to said longitudinal container axis; the container portions being in fluid communication; said container being adapted for carrying said biological material in said first container portion, and a solution different from said material, fully filling said second container portion, which is essentially free of said biological material, and at least partially filling said first container portion so as to be in contact with said biological material; said container further comprising retention means for preventing passage of said biological material from said first container portion to said second container portion.
Methods for freezing biological material making use of the device and container of the invention is also part of the invention.

9. A container for accommodating therein of a biological material, said container having a longitudinal container axis and comprising a first container portion having a first dimension and a second container portion having a second dimension smaller than the first dimension, both measured perpendicularly to said longitudinal container axis;
- the container portions being in fluid communication;
said container being adapted for carrying said biological material in said first container portion, and a solution different from said material, fully filling said second container portion, which is essentially free of said biological material, and at least partially filling said first container portion so as to be in contact with said biological material;
said container further comprising retention means for preventing passage of said biological material from said first container portion to said second container portion. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A kit for freezing biological material, comprising:
-
(a) a device comprising; a cooling unit; a heat insulation unit, having an interface with said cooling unit and a common longitudinal axis passing through said interface transversely thereto; an elongated slot disposed at least in said heat insulation unit and extending along said axis, said slot comprising a first slot portion remote from said interface and a second slot portion adjacent said interface; wherein said first and second slot portions have respective first and second dimensions measured perpendicularly to said axis, the former being greater than the latter; and (b) a container for accommodating therein of said biological material, said container having a longitudinal container axis and comprising a first container portion having a first dimension and a second container portion having a second dimension smaller than the first dimension, both measured perpendicularly to said container axis;
the container portions being in fluid communication;
said container being adapted for carrying said biological material in said first container portion, and a solution different from said material, fully filling said second container portion, which is free of said biological material, at least partially filling said first container portion so as to be in contact with said biological material;
said container further comprising retention means for preventing passage of said biological material from said first container portion to said second container portion.- View Dependent Claims (18)

19. A method for freezing biological material comprising:
-
providing a container having a longitudinal container axis and comprising a first container portion having a first dimension and a second container portion having a second dimension smaller than the first dimension, both measured perpendicularly to said container axis;
the container portions being in fluid communication;introducing into said container a solution and a biological material, such that said second container portion is free of said biological material and is fully filled with said solution and said first container portion is at least partially filled with said solution; and cooling a part of said second container portion which is remote from said first container portion with a cooling means, thereby cooling the solution therein, while insulating said first container portion and a remainder of said second container portion.
