Special Products and Unique Designs

Glass apparatus manufacturing

In our glassblowing workshop we are specialized in the manufacture of high-quality glass instruments for a wiede range of applications. With our experience, precision and care, we produce standard products as well as custom-made products according to customer requirements.

Twin-Filter

The twin filters are made of two different porosities. A coarse layer catches coarse precipitation and prevents the finer pores from clogging prematurely. The fine layer also retains small particles, thus ensuring optimum filtration results. Pre-separation improves the lifetime of the filters in particular. In continuous processes, the filtration performance increases considerably, while the fine sintered layer is optimally protected by the mechanical strength of the coarser porosity. The filters can be manufactured as round and rectangular discs in diameters / edge lengths from 5 mm to 400 mm or as tubes with length up to 500 mm.

Sintered sharpening body

We provide various sharpening bodies in two poresizes for all kind of metal and plastic-bonded diamond tools. The glassbead of the sharpening body has a high hardness and abrasiveness. However, the tool will not be damaged by the relatively soft and open sintered composite material. For more information, please download our brochure (German).

Special laboratory glassware

Next to many standards, our product range also comprises numerous specialties, such as primary packaging glass columns, inlet filters and many more customer specific designs in all kinds of industries.

Casting Technologies

Advanced casting technologies allow the moulding of sintered glass to a large variety of shapes and sizes with porous or even massive structure. Pore diameters of below 1,0 micron at porosities of 35% can be achieved.
