We use redivue P32 from Amersham regularly. We don't use a dispenser as
you describe it. Anyway, I think the convenience is great and we get good
labelling. The pink colour helps to keep track of where your label is.
I've even used it a week after delivery (but only3 days after the
calibration date) and still got good Northerns.
Best of luck,
