ABSTRACT:
A device for facilitating the microscopic and/or spectrophotometric viewing of liquid specimens. The device is an elongated strip having a chamber at one end. The chamber is formed by two generally parallel transparent flat sheets. The device is held by a supporting disc or plug which has a slot or chamber formed for insertion of the strip. The strip with its surrounding disc or plug is inserted in a test tube which has a disc-supporting shoulder formed near the bottom thereof. The disc or plug traps a certain amount of liquid below the shoulder near the bottom of the test tube.
