Kurzfassung

Staining of tissue is a standard method in biological laboratories, but also in clinical environment for diagnostics such as immunohistochemistry (IHC). After a certain incubation period the protocol often requires the transfer of the tissue into another staining chamber. This transfer is a critical step since the thickness of the paraffin embedded slices is smaller than 10 micrometers. As a technical solution a disposable pipette is engineered to have a hole at a specified spot for pressure regulation. This ensures that no under pressure occurs, which might be able to damage the tissue mechanically and/or inhibits the tissue from being sucked into the pipette.

Hintergrund

Staining of tissue is a standard method in biological laboratories, but also in clinical environment for diagnostics such as immunohistochemistry (IHC). After a certain incubation period the protocol often requires the transfer of the tissue into another staining chamber. This transfer is a critical step since the thickness of the paraffin embedded slices is smaller than 10 micrometers and, therefore, not very resistant against mechanical force so it bears the danger to destroy the biological material. In addition, the slice can be easily sucked into the laboratory pipette during transferring procedure.

As a technical solution a disposable pipette is engineered to have a hole at a specified spot for pressure regulation. This ensures that no under pressure occurs, which might be able to damage the tissue mechanically and/or inhibits the tissue from being sucked into the pipette.
