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,
