Calibration of Laboratory Equipments

How do we calibrate an optical densitometer?

Greetings Johanna,

It depends on the type/manufacturer.

First option (free of charge) is if the equipment has an auto-cal function.

Second option (low to medium cost) are standard calibration strips if your equipment can use them (just follow up the instructions included in the strip package, it's really easy).

Third option (medium to high cost) is to send it to an accredited lab/calibration company to have it done for you and also get a certificate.

Regards!
