Further Instruments

Bareiss DigiTest II

Hardness tester for soft tissue and polymers according to shore, IRHD and VLRH. Used for characterizing connective tissue, such as cartilage, soft, and synthetic materials. The setup includes a test stand, a receiving arm with the measuring device for forces up to 20 N, and the electronic measurement and recording unit. The samples are placed on a metal sample holder with a milled edge.

Home-built Indentation System

Calibrated indentation system with a mm-sized indenter sphere, suitable for the mechanical characterization of bulk materials.

SPECIMEN PREPARATION EQUIPMENT

CRYOTOME - CRYOSTAR NX50

For cutting specimens (0.5 μm-500 μm) (such as tissue, organoids or hydrogels) prior to histological and optical characterization.

This figure shows three photographs of the Cryostar NX50 Cryotome.

CRYO-BALL MILL - RETSCH

The ball mill will be applied for preparation of soft, hard and cryogenic samples for chemical extraction, radical measurement or electron microscopy. The milling cups of metal, ceramic or agate can be used for instance for breaking down hard tissue or polymer samples, and further milling to powder in micrometer size.
