We are offering liquid mercury. We can export 99.99% and 99.999% purty mercury to foreign.

We are offering chymotrypsin. Trypsin-chymotrypsin is the co-crystal of chymotrypsin and trypsin so it has the properties of both. The activity of hydrolyzing casein is as much as chymotrypsin. But the activity of its chemotrypsin to hydrolyze n-benzoyl-l-tyrosine ethyl ester(btee)is three times higher than chemotrypsin.the activity of hydrolyze ester bond similar to that of trypsin. It is stable when dry and easy to be inactivated in solutions. The optimum ph is 7.0-8.0. Is purified by re-crystallization, and then by ultra-filtration.

We are offering mercury. Molecular formula: hg = 200.61 traits: room temperature only liquid metal, a specular gloss. Specifications: hg content of not less than 99.99%min chemical composition%: silica ( si ) 0.0005 iron ( fe ) 0.0003 calcium oxide ( ca ) 0.0001 lead, copper, and zinc trace.
