<p>A cubical or rectangular frame of interchangeable columns and stringers joined by corner blocks has an interchangeable, permeable or perforated base plate and is used as a mounting for a wide variety of thin film carriers, sandwich chambers, cassettes, liquid cells for continuous analysis or heaters/coolers as required. They are variously fixed to the rods of the frame using alternate distance pieces and spacers. The accessory, in kit form, is versatile and flexible in use e.g., for falling horizontal, continuous or interactive thin film chromatographic methods.</p> |
