An immediately 'ready-to-use' transport and storage solution.
The AQIX® RSI solution is an immediately, 'ready-to-use' transport and storage solution for the collection of a wide range of cell and biopsied tissue samples. Samples can be placed directly into the solution without any further manipulation to either the sample or RSI solution solution.
For more details on reconstitution see our Standard Operating Procedures on Collection and Transportation.
Formulation
AQIX® RSI solutions are supplied as a sterile solution in 4 - 8 rigid, sealed, leak-proof transparent Nalgene®containers each holding 125 mL of carbogenated AQIX® RS-I (1X) 'ready-to-use' solution.
Each AQIX® RSI solution is prepared to order by Aqix Limited.
Reconstitution
No further manipulation of the sterile RSI solution is required prior to use. Additional antibiotic preparations may be required depending on procurement conditions.
Shelf life
AQIX® RS-I 1x 'ready-to-use' solution has a shelf life of 8 months from the date of preparation when stored at 2-8°C under dark conditions.
Publications
Below are listed peer reviewed published papers and audit trial reports which demonstrate the uses of the AQIX® technology.
