We are happy for other PSP lab operators to use the Winchester bottle recycling facility (there’s a collection cage labelled “KalVista” in PSP’s bin store) but those who dispose of Winchester bottles via KalVista's collection cage must ensure their empty bottles have been washed and dried out before replacing the bottle caps so that there is no chemical residue.

Existing bottle labels must be removed or defaced so that the original contents of the Winchester bottle cannot be identified.

Fisher Scientific will refuse to empty the cage if these conditions are not met.
