ABSTRACT:
Method and apparatus are provided for making multiple continuous or discontinuous gradients. Individual vacuum systems draw the gradient material from a common mixing chamber and deliver it into identical receptacles where each gradient is formed. A battery of syringes can be used to create vacuums on each individual chamber, and an opposing battery of syringes can be used to deliver gradient material to the mixing chamber. By varying the ratio of syringes generating vacuums to syringes delivering gradient material and/or initial solution volumes, gradients of various shapes can be produced.
