    Abstract: A culture flask comprising a culture chamber in a flask body comprising an even bottom wall with a growth surface on the top side, an even cover wall at a section from the bottom wall, and side walls that bridge the distance between the margins of the bottom wall and cover wall, an opening that is in adjacent regions of a side wall and the even cover wall at a distance from the bottom wall, and a hollow cylindrical flask neck that is connected to the margin of the opening and is aligned at a sharp angle to the growth surface so that the serological pipette, a scraper, a cannula or another elongated device for adding or removing material can be placed on the rear corners of the growth surface from the outside through the flask neck.

    Abstract: A method for dosing a liquid using a pipette with adjustable dosing step size and an indicating equipment and a syringe that can be operated using the pipette. The syringe is detachably connected to the pipette. The dosing step size is set, or the dosing step size set before is maintained. The dosing volume adjusted via the dosing step size is indicated. Liquid is aspirated into the syringe. Dosing steps are performed, counted and the number of performed dosing steps and/or the number of dosing steps still possible without refilling the syringe is determined and indicated. After performing the maximum number of dosing steps possible without refilling the syringe, either the syringe is detached, or the steps are performed again. The overall performed number of dosing steps with the set dosing step size is counted, and/or the number of dosing steps still possible without refilling is determined and indicated.

    Abstract: A single-use bioreactor, suitable in particular for use in a parallel bioreactor system for applications in cell culture and/or microbiology, a head plate for such a single-use bioreactor and a process for manufacturing the single-use bioreactor and the head plate. The single-use bioreactor comprises a head plate, a dimensionally stable container and a mixer, the head plate and the container enclosing a reaction chamber, and the mixer having a mixer shaft and a stirring member, said mixer shaft being mounted rotatably about a rotational axis in a bearing and the stirring member being fastened torsionally rigidly to the mixer shaft. The mixer and the bearing are arranged entirely within the reaction chamber and the mixer shaft has a magnetic portion which is arranged and adapted in such a way that it can be coupled magnetically in an axial direction to a rotary drive.
