Abstract
A heat transfer bladder system is incorporated into the interior of a laboratory work bench assembly and serves to control the temperature of a work surface of the work bench. The bladder contains a flowable media such as a fluid or gel which is heated or cooled so as to be able to control the temperature of the work bench work surface. The bladder system can include an external temperature control or an internal temperature control to control the temperature of the bladder fluid or gel. The bladder assembly may include through passages for adjunct instruments that can be used in conjunction with the work bench. The bladder can be formed from an elastomeric flexible material, or from a metal such as copper or stainless steel. The temperature control media can be circulated into and out of the bladder, or it can be contained in the bladder.
