1. A device for maintaining a constant temperature for chemical analysis, comprising:
- at least one slide having a multi-layer chemical analysis film for receiving an analyte to be measured, said film being supported by a slide frame, said slide frame supporting said film at an intermediate portion thereof so that upper flat surfaces of said slide frame are disposed at an elevation above an upper surface of said film;
a conveying belt for conveying said slide on a first surface thereof, and a sealing guide belt for sealing said upper flat surfaces of said slide frame so that a first surface of said sealing guide belt which is disposed parallel to said first surface of said conveying belt bridges said upper flat surfaces to form a closed chamber above said upper surface of said film and said analyte to minimize evaporation of said analyte within said closed chamber;
first and second drive rollers and an electric motor operatively disposed to rotate at least one of said drive rollers to transport said conveying belt; and
means for maintaining said slide at a constant temperature as said slide is conveyed and sealed.

Abstract
A device for maintaining a constant temperature for chemical analysis performed with slides having at least one layer adapted to absorb a substance to be analyzed. The slides are conveyed upon a lower conveying belt which may have projections or recesses formed therein for receiving the slides. The upper portions of the slides are sealed by a sealing guide belt which has a surface disposed parallel to and adjacent the conveying belt with the slides passing therebetween. A heater may be provided within the conveying belt and the guide member provided within the sealing guide belt which may itself perform a heating function.
