Abstract
Die Erfindung betrifft eine Probenaufnahmeeinrichtung (100), insbesondere zur Kryokonservierung mindestens einer Probe, die ein Buendel (10) aus einer Vielzahl von schlauchfoermigen, flexiblen Probenkammern (11, 12, ...) und eine Halteeinrichtung (20), mit der das Buendel (10) der Probenkammern verbunden ist, umfasst. Die Halteeinrichtung (20) weist eine Vielzahl von Halterahmen (21, 22, ...) auf, die in einer Laengsrichtung des Buendels (10) angeordnet sind.

 

WO2005001439 A UPAB: 20050202 NOVELTY - Sample holder for cryo-conservation of biological or medical materials (20) comprises a number of holding frames (21, 22) arranged along the bundle (10) of tubular, flexible sample chambers (11, 12). DETAILED DESCRIPTION - Sample holder for cryo-conservation of biological or medical materials (20) comprises a number of holding frames (21, 22) arranged along the bundle (10) of tubular, flexible sample chambers (11, 12). The spaced, rectangular holding frames form a carrier on which the process chambers are arranged adjacently. Inter-frame spacing exceeds frame thickness. The frames lie concisely together along the bundle. They form a stack (30) held by a clamp. One, more or all frames integrate data memory, or it lies between them. Sample chambers are fastened to the frame, forming a plane side surface parallel to the planar extent of the frame. Area of the sample chamber cross section varies along its length, optionally periodically. The chambers are subdivided by chamber walls. The chamber wall has pores or is a dialysis membrane. An INDEPENDENT CLAIM is included for the corresponding method of manufacture. USE - A sample holder for cryo-conservation of biological or medical materials, including cells, tissues, fluids and organs. ADVANTAGE - Construction is simplified, overcoming conventional manufacturing difficulties. Handling is facilitated, especially when charging with samples, freezing and during subsequent sample extraction. The design is suitable for large-scale cryo-conservation.
