Abstract: Room Air Gel Dryer contains a system of hinges for movement and alignment of frames. It has another system of latches and thumb screws for tightly holding or releasing different frames. Both of the above described systems keep various separate components stay and work together as one unit. Wall plates not only hold this gel dryer horizontal but also make it stand with excellent stability. Special grooves present in the lateral sides assist in separating different frames and in the collection of dry acrylamide gel-cellophane sandwich.

Abstract: The invention described holds dialysis bag and other similar articles containing delicate membrane securely in place so that biological solution can be added or collected, safely. The Dialysis Bag Holder contains bottom, vertical and top plates, cradle tubes and a funnel holding mechanism. The bottom plate holds vertical plate and cradle tubes. The vertical plate, besides providing additional support to cradle tubes, holds the top plate firmly in place. The top plate located over the tip of cradle tubes, seats funnel for pouring large volume of sample. Cradle tubes, attached permanently at an angle to the top of bottom plate, hold dialysis bags. The angle of attachment makes cradle tubes have an ascending slope. The concave holding surface of cradle tube complements with the cylindrical body of the bag or similar articles. The entire unit provides stability to the dialysis bag before, during and after loading biological sample.

Abstract: The described Chromatography Buffers Center holds various types of buffers required in the purification of a variety of biological molecules. The unit consists of a base plate, a handle, reservoirs and lids with attached stop pins. The vertical handle, which is an extension of base plate, gives a nonslippery grip to lift and carry the unit. A short bent hook present in the handle is useful to mount the unit in a clamp that is attached to a common laboratory stand. The hook permits lateral movement of the unit even by a simple push with a finger. Base plate allows the unit sit on any flat surface of work bench, shelf or magnetic stirrer. Reservoirs attached permanently to the top of base plate hold different types of buffers in their chambers. Through drain tubes present in the rim of base plate, these buffers can be drawn to develop chromatography columns. Lid on each reservoir protects buffer from air born dust and evaporation.
