Equipped with a sleeve device, it can be quickly connected to a vacuum device,Create a vacuum inside the nuclear magnetic resonance to better protect the sample.

Medium pressure valve nuclear magnetic tube

VALVED NMR TUBES FOR INTERMEDIATE PRESSURE

This valve adopts * sealing design technology, and its performance is * better than any valve currently produced by other manufacturers. The PTFE valve stem is the primary sealing component of this valve. Fluororubber on valve stem0The circle is wrapped inside the PTFE valve stem, which has elasticity and chemical stabilityOThe circle is wrapped in a PTFE sleeve. Ensure the chemical inertness of the entire valve,Ensure the normal progress of the experiment. The use of this nuclear magnetic tube can make some special experiments more convenient, such as:Experiments that require the addition of inert gas protection, the addition of active gaseous substances under certain pressure, and the suppression of low boiling point reagent volatilization or reagent volatilization at high temperatures, etc.

Thin walled nuclear magnetic tubes are suitable for pressures below600 kPa(6bar,87psi)The experiment,The usage pressure of thick walled nuclear magnetic tubes can reach1200 kPa(12bar,175psi).(Please refer to the attached table for complete details)The pressure resistance of glass is influenced by various factors and is unpredictable to a certain extent, especially when there are scratches and improper handling. Therefore, when used at a certain temperature and pressure. We must be cautious and careful. The sample tube section is composed ofASTM1waitAMade of glass(for examplePyrexglass)Can withstand the highest temperature of approximately230°CAnd can tolerate it120%CThe temperature changes within will not cause damage under thermal shock.
