The present invention relates to a shipping container for cryopreserved biological samples in which a cryopreserved sample can be maintained on arrival at its destination for a period of time, for example several months.

Shipping container

A sample heating/cooling device () comprises a plurality of members () operable in use to heat and/or cool one or more samples (). Each member () has a sample contact surface and is biased towards a resting position under the operation of a biasing means. The members () are movable independently of one another against said bias under the application of a force on the sample contact surface and so are able to conform to the shape of a sample placed on the members to provide a uniform heating/cooling profile. The members () may be mounted in a heating/cooling element () and adapted to conduct thermal energy between the sample () and the element (). The device () is particularly suitable for thawing frozen sample bags having an irregular shape. A corresponding method is also described.

Device and method for heating or cooling a sample

Disclosed is a computer-implemented method comprising: obtaining first data indicative of electric power supplied to a cooling apparatus during a cooling operation on a biological sample, the cooling operation having a given cooling condition; obtaining second data associated with a reference cooling condition; determining, based on the first data and the second data, whether the given cooling condition has a predetermined relationship with the reference cooling condition; and in response to a determination, by the determining, that the given cooling condition has the predetermined relationship with the reference cooling condition, outputting a control signal. The given cooling condition for the 'live' data cooling operation may thus be validated against a reference cooling condition.

Method and system relating to cooling conditions for a biological sample

The invention provides a method of thawing a sample comprised in a container, the method comprising the steps of: a) calculating an agitation program as a function of either or both of the sample volume and the type of the container, and the ice fraction in the sample, and optionally the thermal conductivity of the sample container; b) agitating said sample according to the program to agitate at least one region of the sample; and c) changing the agitation program applied to at least one region of the sample in response to changes in the sample volume and/or sample ice fraction. The invention further provides a method of reducing shearing to cells during a method of agitation, and methods for thawing a sample wherein a sample container is differentially heated. An apparatus for use in the methods is also provided, as is an apparatus for thawing and/or cooling a sample which comprises a resilient vessel wall.

Thawing methods and apparatus

A sample heating/cooling device comprises a plurality of members operable in use to heat and/or cool one or more samples. Each member has a sample contact surface and is biased towards a resting position under the operation of a biasing means. The members are movable independently of one another against said bias under the application of a force on the sample contact surface and so are able to conform to the shape of a sample placed on the members to provide a uniform heating/cooling profile. The members may be mounted in a heating/cooling element and adapted to conduct thermal energy between the sample and the element. The device is particularly suitable for thawing frozen sample bags having an irregular shape. A corresponding method is also described.

Apparatus for illuminating the retina of an eye. The apparatus includes an illumination device and a lens system. The illumination device and the lens system combine to provide incident illumination from an apparent point source located within the lens system. The apparatus also includes an illumination transfer device. The illumination transfer device has two foci and the apparent point source of the lens system is provided at a first focus point of the illumination transfer device and an eye is accommodated at a second focus point of the illumination transfer device. The illumination transfer device transfers the incident illumination from the apparent point source into the eye to illuminate the retina.
