[Histonet] CALIBRATING SCALES

[Geoff McAuliffe]

Hi Brian:

    I must admit that I was skeptical until I looked in the Fischer 
catalogue, a complete set of weights lists for $980. That said, what is 
the matter with your "old" weights? Maybe if you need great accuracy to 
4 decimal places you might need some very precise weights, but otherwise 
I think not. What sort of reagent needs that degree of precision?
    When we had Mettler come out and calibrate out balances the 
technician always had his own set of weights. I would talk to the 
manufacturer, the vendor and whoever is providing service.

The weights that we having using for years are no longer the correct standard for calibrating the scale and biomed tells us we need to order special weight that will exceed $1,000. Does anyone know of a service that will come out and calibrate the scale. That seems to be a more cost efficient way of taking care of this problem. Any advice would be greatly appreciated.
