How Gel Dryers Are Used In The Laboratory

May 22, 2016, 7:29 PM |

There are a variety of different gel dryer units which are commercially available for different gel drying applications in the laboratory. The exact drying methods used differ depending on the nature and size of the gels involved. Polyacrylamide gels of standard size can be dried by oven-like air drying systems, while gels containing corrosive compounds must instead be dried by vacuum dryers which feature filter traps. Sequencing gels (and other larger gels) or multiple standard size gels need a large drying surface with drying enhanced by a vacuum. 

The gels are normally dried between two sheets of porous cellophane and come out of the gel dryer completely flat and clear with a glossy finish.Are you still searching for Sodium Polyacrylate manufacturers or Sodium Polyacrylate factories? china Sodium Polyacrylate We provide China’s best Sodium Polyacrylate for customers all over the world. The dried gels can be used for further detection and analysis by photodocumentation, densitometry or autoradiography. This gel drying process also makes them suitable for long-term storage.Are you still searching for Potassium Polyacrylate manufacturers or Potassium Polyacrylate factorieschina Potassium Polyacrylate We provide China’s best Potassium Polyacrylate for customers all over the world. There are also heat vacuum method dryers available which can dry gels rapidly and evenly. These types of dryers come with separator traps which capture corrosive liquids and vapors from the gels as they dry. 

A manual gel dryer process is also used in some laboratories. Manual drying uses a solution containing 10% glycerol and 20% ethanol, drying frames and as with other methods, cellophane sheets.For China water treatment PAM, water treatment agent,water treatment agent we are the best water treatment PAM suppliers, and provide various kinds of water treatment PAM pro In a manual gel dryer procedure, the gel to be dried must first be equilibrated in a drying solution for a minimum of half an hour to reduce swelling and make the gel more flexible once dried. 

The next step in the gel drying procedure is to place the gel between two sheets of moistened cellophane after pipetting 1.2 ml of drying solution on top of the gel.For China Drinking water grade Polyacrylamide, we are the best Drinking water grade Polyacrylamide sDrinking water grade Polyacrylamide and provide various kinds of Drinking water grade Polyacrylamide products with the lowest price. The cellophane sheets containing the gel are then clipped together and left to dry for a minimum of two days. As you can imagine, this is a much lengthier and labor intensive process than that offered by an automated gel dryer unit. There are also quite a few things which can go wrong along the way in the manual process, which leads to the commercially available units being preferred in most laboratories where resources and bench space permit. 

Yet another alternative to manual drying as well as the more expensive vacuum-based gel drying units is also available. This is a lower-tech but simple and cost effective method of drying gels; both agarose and polyacrylamide gels can be dried using gel drying film; essentially pre-treated film which is used along the same lines as the manual method but resulting in much more rapid drying.We are professional polyacrylamide manufacturer and provide high quality of China anionic polyacrylaanionic polyacrylamide products which are in hot sale PAM Products around the world. This allows the gels to be viewed even as they are drying and provides a virtually gas-impermeable barrier. 

The exact type of gel dryer which is preferable for a given application depends on the requirements of the gel and the other parameters of the application in question. Other factors such as available space in the laboratory, resources available and the throughput of gel drying required all come into play in the question as well. For those facilities which have a large volume of gels, however, the commercially available automated dryer units are a very welcome addition to the laboratory worth every millimeter of bench space that they occupy.
