摘要:
A cryostat is described for use in absorption spectrophotometric measurements. With liquid nitrogen as coolant optical cells of variable path length can be maintained at any temperature from −194 to −40°C with a precision of ±0.1°. An optical cell assembly is also described which eliminates the problem of cracking of windows due to rapid temperature changes.
