Size doesn't matter with the semi-micro range of Orion pH electrodes
The electrode body is approximately 6mm in diameter which means samples as small as 0.2mL can be measured, making it ideal when measuring in small vessels such as test tubes.
Models are available in all ranges including the ROSS, Tris, PerpHect, AquaPro and Standard Line pH electrodes with glass, epoxy and sure-flow designs.
This allows for a wide range of applications to be covered including viscous and difficult samples in clinical, pharmaceutical and food laboratories.
