[Histonet] calibration of pH meter

[Jon St.Onge]

Akemi,

We calibrate our pH meters daily using standards of pH 4.0, pH 7.0, and pH 10.0 to cover the range of our testing.  
Check the owner's manual for your pH meter and follow the calibration procedure and recommended occurrence.
The pH standards can be purchased through many suppliers.

Good morning everyone,

I am curious how frequently you all calibrate your pH meter,  
particularly when you make up solutions for muscle bx's?  Do you do  
it daily, weekly, or monthly?  I am trying to come up with an  
acceptable standard in a clinical histology lab, verses a biotech  
lab, which makes-up large quantities of reagents on a daily basis.

Thank you in advance for your information,
Akemi
