Many biological systems have a narrow temperature range of operation, meaning high accuracy and spatial distribution level are needed to study these systems. Most temperature sensors cannot meet both the accuracy and spatial distribution re...
Utilization of a High-Pressure Vibrating Tube Densimeter for Liquids at Temperatures Down to 100 K [0.03%]
