These short molded components are fused to measurement electrodes and serve as filling/draining ports for the electrodes. The beaded edge is ideal for connecting rubber or plastic hoses. The ports are usually made of lead, borosilicate, and soda glass.

If required, we can supply capillaries and tubes with predetermined break points. For this purpose, the component is notched at the required breaking location. If the component is then subjected to a bending force, it will break at the notched point. To prevent unintended breakage, we recommend using medium or thick-walled tubes and capillaries.

Twisted glass tubes and capillaries are produced simply by heating and twisting. By this means, the tubes obtain a large internal surface in relation to their length, enabling them to be used e.g. as cooling sections. Another application area is for ornamental and design articles.

Cloning cylinders or rings are ideally suited for separate cloning if individual cells or cell groups on a nutrient solution. A specific cell or cell group is separated from the other cells in the nutrient solution by simply placing the cloning ring over it. The rings are made of high-grade borosilicate glass, and can be thermally sterilized without problems. The ring faces are ground perfectly flat, enabling the rings to be fixed e.g. to the floor of a Petri dish by means of a suitable grease. Subsequently, the nutrient solution is filled into the ring. The grease provides a seal between the ring and the Petri dish, whereby the precision-ground flat end ensures that very little grease is required to provide an optimum seal. The same applies in the case of Petri dishes prepared with a nutrient solution – here, the seal is provided simply by pressing the ring into the solution and down to the floor of the dish. Cloning cylinders

As a special service, we offer glass tubes and cylinders with calibrated inside diameters. Hereby, a special tool is used to bring the internal diameter precisely to the desired shape and dimension. Apart from the standard circular shape, the tubes can also be square or conical. Moreover, the outer tube diameter can be calibrated by means of cylindrical grinding. This grinding procedure results in a matt outer surface, which can be corrected by subsequent “technical polishing”.
