Kolga
Marinelli
Beakers

The patented Kolga Marinelli beakers are available in many different sizes with two lid types available: the screw-on style or the traditional snap-on style.

The Kolga beakers have a unique patented tight fitting lid to prevent spillage with a built-in gripping handle to facilitate easy removal of the beaker from the sample counting shield.

Both lid versions have been tested for air tightness at least 1 psi positive pressure for 24 hours.

The Screw Top versions have a built in sealing ring to assure leak proof operation for sensitive applications.

The Marinelli form factor improves counting efficiency in gamma counting systems.

The KB Model beakers are available for up to 3.5 inch detectors. Please see our specifications sheet for details and the correct part number for your application.
