Most of our nanoparticles are stable for approximately 6 months to 1 year if stored properly. Please see our technical specifications and/or MSDS for more information. These can be found in the product catalog after clicking on the specific product you are interested in.
For inorganic solvent, the concentration depends on the amount ordered unless other concentration is specified. 5mg (1mg/mL), 10mg (2mg/mL), higher amounts 25+mg (5mg/mL). Water soluble products are 1mg/mL unless specified otherwise. High concentration is also available as a custom order.
Yes, as long as the concentration is feasible and the solvent is capable of dissolving the nanocrystals and is available. Toluene soluble products can be provided in other organic solvents. Hexanes and chloroform can be substituted for no extra charge; other organic solvents can be discussed as a custom order. Our water soluble products can be modified to be soluble in some alcohols.
Iron oxide is the only product offered in powder form. The availability of other products can be discussed as a custom order on a case by case basis.
