ABSTRACT:
A handling device for enabling a technician to dialyze a solution without direct contact with the solution to be dialyzed. The device comprises a polycarbonate rod having an internal bore and a test tube gripping element at one end. At the other end is clamped a section of dialysis tubing, there being a passageway from the test tube-gripping end through the internal bore and into the dialysis tubing. The dialysis tubing is knotted to form a dialysis bag. The rod is manipulated to grippingly engage over a test tube containing the solution to be dialyzed and the test tube is inverted to transfer its contents to the dialysis bag, after which the device is supported in inverted position with the bag in a dialysis bath. After dialysis, the device is removed and reversed, returning the dialyzed solution to the test tube.
