ABSTRACT:
Apparatus for examining a sample by microscopy, spectroscopy or crystallography under controlled environmental conditions. The apparatus comprises a sample chamber (1) which is fed by a gas stream (19) having a known vapor content, which is generated by mixing two gas streams (18&16), one substantially saturated in a volatile substance (18) and one substantially free of the volatile substance (16), in a controlled manner. The temperature of the apparatus, and particularly of the sample chamber (1), is accurately controlled and regulated by temperature controller (7).
