First Claim
Patent Images
1. An automated laboratory workstation comprising:
- a receptacle containing a vaporizable substance;
a robotic means for performing a sequence of laboratory operations with respect to the receptacle;
means for heating the vaporizable substance, including the receptacle;
a cover for covering the receptacle, disposed in opposing relation thereto;
means for effecting temperature control of the cover, wherein the means for effecting temperature control of the cover maintains the temperature of the cover above the temperature of the substance; and
means for moving the cover relative to the receptacle to cooperatively engage the cover and the receptacle, including a means for positioning the cover over the receptacle.

Abstract
A heated cover for a receptacle containing a vaporizable substance. The cover is heated to a temperature above the temperature of the substance so as to prevent condensation of vapor evaporated from the substance. A device for placing and removing the cover with respect to the receptacle is designed in connection with a temperature-controlled heating/cooling plate which controls the temperature of the contents of the receptacle.
