SYSTEM FOR PREPARING SAMPLES FOR ANALYSIS USING A SHOCK FREEZER

摘要

An automated system for preparing samples for analysis comprises a robot movable along x, y and z-axes. The robot includes a syringe including a needle or capillary for drawing a sample from a vial into the needle. A shock freezer includes a closed container having an amount of cryogenic fluid and a tubing in contact with the fluid, the tubing including one end for receiving the capillary, and a relief valve communicating with the fluid that is closed when the capillary with a sample is inserted in the tubing to force the fluid to flow to the outside through the tubing. A heater is provided for thawing the sample in the capillary after being frozen. A receptacle is provided for receiving the sample after thawing for analysis.
