   Product Detail


The Mini-Assay type 6-20 comprises a high voltage supply, discriminator, and scaler with crystal controlled timer in a single unit.  The illustration shows the instrument connected to the type 43 well scintillation probe supported by the demountable stand together with a lead shield.  This combination makes an ideal unit for either a small RIA laboratory or back up to a multiple counting system.


For use in Microbiology labs where counting periods are in minutes rather than seconds you require the Model Type H.
