We calibrate our pH meter every day that it's used, which can be daily during heavy workload weeks, using multiple calibration buffers.

Subject: [Histonet] calibration of pH meter


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
