TRANSMISSION CAPSULES FOR EASY SAMPLE STORAGE
The TPT capsule complements the traditional sandwich preparation. It can be used for dry or moist powders or pastes and is compatible with the STOE transmission sample holder inserts. This single-use capsule allows an easy storage of the measured sample for traceability or further analysis, e.g. in pharmaceutical research. It has been developed in cooperation with F. Hoffmann-La Roche AG by Gimelli Engineering AG and been used for many years.
We are now pleased to bring this development to you, and we included it into the STOE product range.

The TPT capsule is available in several variants to suit your needs:

For applications with samples up to class 3B, in which no solvent is present.
For applications with samples up to class 4, in which solvents may also be present. For class 4 specimens, the openings in the snappers must also be sealed by using e.g. nail polish.
Depending on the substance quantity / hazard class, the aperture can be selected with a diameter of 3 mm (sample quantity approx. 2.8 μl) or 8 mm (sample quantity approx. 20.1 μl).
