An inexpensive multichannel pipet designed to deliver small volumes of liquid simultaneously to wells in a multiwell plate can be prepared by students in a single laboratory period. The multichannel pipet is made of disposable plastic 1 mL syringes and drilled plastic plates, which are used to make plunger and barrel assemblies. Application of the multichannel pipet on a combinatorial chemistry chemiluminescent esters laboratory exercise is described. (Contains 3 figures and 2 notes.)
