Abstract
An air-barrier agent for an aqueous reagent or an aqueous specimen having as an effective component a mixture of a chain hydrocarbon and a silicone oil immiscible with the aqueous reagent as well methods of using and making the same.
Claims17
An air-barrier agent comprising a mixture of a chain hydrocarbon and silicone oil, wherein the silicone oil has a kinematic viscosity of 100 cSt or less, and the mixture is immiscible with an aqueous reagent or an aqueous specimen, and has a specific gravity lower than that of the aqueous reagent or the aqueous specimen.
A method for storing an aqueous reagent, or an aqueous specimen comprising:
- contacting a mixture of a chain hydrocarbon and a silicone oil with the aqueous reagent or the aqueous specimen, wherein the silicone oil has a kinematic viscosity of 100 cSt or less, and the mixture is immiscible with the aqueous reagent or the aqueous specimen, and has a specific gravity lower than the aqueous reagent or aqueous specimen.
