The 9CB temperature block, developed by Quantum Northwest, is a commercially available solution for temperature control in neutron scattering instruments at NIST. The block features 3 independently controlled temperature zones, each controlling 3 sample wells, allowing for precise temperature management.
Key features of the 9CB include:
– Temperature range: -10°C to 110°C (with total range -40°C to 140°C)
– Rapid equilibration: 10 minutes or less for temperature changes of 50°C or less
– Quartz windows for optimal temperature stability and laser alignment
The main advantage of the 9CB is its rapid equilibration time, which is significantly faster than other fluid-controlled blocks that can take up to an hour to reach desired temperatures. The quartz windows ensure proper optical transparency and alignment of the sample block.
