An apparatus for the micro-dissection of tissue with a fine needle, which is arranged on holder movable in space along three axes and the tip of which can be moved with the holder relative to the tissue, which is to be severed, wherein the needle is coupled with an oscillating drive mechanism, which causes the needle to oscillate in the longitudinal and/or transverse direction at a predetermined amplitude and frequency.

Apparatus for the micro-dissection of tissue

In a process for mixing liquid samples to be analyzed, the liquid sample contained in a sample container is moved and mixed by a mechanically oscillated air column in contact with at least part of the liquid sample surface, the air column being excited with a frequency in the resonant range of the system formed by the air column and the sample liquid.

Process for mixing liquid samples to be analyzed, as well as apparatus

An electrode assembly for electro-chemical measuring systems includes an electrode member having a selectively sensitive membrane disposed in its front end and an electrical conductor extending from the membrane rearwardly through the electrode member. A holding member is provided to secure the electrode member in sealed relation with the membrane disposed within a measuring chamber. The holding member provides a spring loaded sealing force to the electrode member and can be applied and removed without rotation of the electrode member.
