320°F Cryogenic Liquid Nitrogen Valve Buy Valves from

The customer needed a valve that would allow liquid nitrogen to go through it but not freeze up when the valve was turned. They also needed to control the amount of nitrogen going into the tank. The valve required -320 degree F nitrogen going through it while controlling the amount of the liquid.

2/2 4 Cryogenic and Liquid CO Valves Cryo/ Brass Body

?“LT” suffix valves are built to control cryogenic fluids, including liquid nitrogen (-320?F/-194?C), liquid argon (-303?F/-184?C), and liquid oxygen (-297?F/-181?C) ?All suffix “LT” valves are degreased, cleaned, tested free of moisture, and black light tested for hydrocarbons ?Liquid CO 2valves are suitable for remote

Structural characterisation of Arquad? 2HT75

The sorption behaviour of Arquad ? 2HT-75 in soils also differs from that of HDTMA and ODTMA . Being comparatively less toxic to soil microorganisms, Arquad ? 2HT-75 derived organoclays might be more suitable for contaminant degrading microbes to thrive on them and thus successful development of bio-reactive organoclays .

Cryogenic Solenoid Valves from JAKSA

Cryogenic Solenoid Valves from JAKSA. High performance direct acting or pilot-operated valves with brass bodies and PTFE seals, suitable for continuous service with liquid nitrogen (LN2), liquid carbon dioxide (LCO2) and other cryogenic fluids down to -196°C.

Structural characterisation of Arquad ? 2HT75

Xi et al. [11] described that with Arquad? 2HT-75 would also produce a similar arrangement (a) at surfactant concentrations equivalent to – CEC of the pattern of the surfactant molecules in the clay minerals due to the bentonite clay mineral, lateral monolayer and lateral bilayer con- fact that Arquad? 2HT-75 is also a double chain

Remediation of hexavalent chromium through adsorption by

Unlike hydrophobic organic pollutants, the potential of organoclays to adsorb inorganic ionic contaminants is relatively underexplored. The present study attempts to characterise bentonite (QB) based organoclays synthesised from a commercially available, low-cost alkyl ammonium surfactant Arquad ? 2HT-75 (Aq) and test their ability to adsorb hexavalent chromium (Cr (VI)) in aqueous solution.
