GelAir Drying Overview

Easy gel drying with the GelAir dryer:

1. Place a sheet of cellophane over the plastic drying frame on the assembly table.

2. Lay a gel on top of the cellophane.

3. Place another sheet of cellophane over the gel.

4. Place the metal square frame on top.

5. Clamp the drying frames together using 8 green drying frame clamps, and slide the drying frame into the dryer.



The GelAir Drying System is perfect for drying polyacrylamide and agarose gels. Dried between two sheets of cellophane, the gels come out completely clear with a glossy finish, ideal for densitometry, photodocumentation, autoradiography, overheads, and long-term storage.

The heated drying chamber works like a convection oven to dry mini gels in 45 minutes or 20 x 20 cm gels in 60 minutes, rivaling the speed of conventional gel dryers that require a vacuum pump. Drying times may vary depending on percentage and thickness of the gel. The dryer holds up to four drying frames at once.

GelAir Drying Frames

The GelAir drying system includes two complete drying frames made of a durable, molded plastic base with a stainless-steel top frame. GelAir Drying Frames may be added to or removed from the GelAir Dryer at any time while it is running. Each frame holds four mini gels or one 20 x 20 cm gel. When the dryer is fully loaded, four large gels or 16 mini gels can be dried at once.

GelAir Assembly Table

The GelAir Assembly Table is a custom workspace for assembling GelAir Drying Frames. Any excess liquid is neatly caught by the table, saving cleanup time.

GelAir Cellophane Support

GelAir Cellophane Support is precut to fit GelAir Drying Frames. Gels dried between two sheets of cellophane are perfectly clear with a glossy finish.

Gel Drying Solution

Bio-Rad's Gel Drying Solution is a pretreatment for polyacrylamide gels that helps prevent cracking during air drying. Just 10 min of equilibration in the solution before drying the gels prevents excessive swelling and cracking of the gels.
