Abstract
This cryogenic preservation or vitrification device (1) comprises: an accumulator (2) including a first volume of pressurised hydraulic oil; a control system controlling a valve (20) capable of releasing a second volume of hydraulic oil from the accumulator toward a cylinder (55) by means of a pipe (4); a cylinder (55) including a piston (6) configured to be driven by the second volume of hydraulic oil and to displace a first volume of cryogenic fluid to a cryogenic vessel (7) intended to receive a sample (8) to be cryogenically preserved.
Claims13
A cryogenic preservation or vitrification device, comprising:
- an accumulator including a first volume of pressurised hydraulic oil (V1H);
- a control system controlling an opening and closing of a valve capable of releasing a second volume of hydraulic oil (V2H) from the accumulator toward a cylinder by means of a pipe;
- said cylinder including a piston configured to be driven by the second volume of hydraulic oil (V2H) and to drive a first volume of cryogenic fluid (V1A) in a cryogenic vessel intended to receive a sample to be cryogenically preserved,
- wherein the piston includes an end element configured for collecting a volume of cryogenic fluid in an intermediate chamber.
