A method and biological sample analyzer is described that adjusts airflow within a housing based upon altitude. A first volume of air is moved by at least one fan within a housing of a biological sample analyzer. A temperature of the first volume of air is measured within the biological sample analyzer with a temperature sensor within the housing of the biological sample. Power output of at least one heater positioned within the housing of the biological sample analyzer is measured. The measured power output of the at least one heater is analyzed at the measured temperature within the biological sample analyzer. And, the fan is adjusted to move a second volume of air different from the first volume of air by comparing the measured power output of the at least one heater and expected power output of the at least one heater.

The invention relates to a device for sealed transfer between two enclosed volumes, comprising a first flange and a second flange (10) which define a passage opening into the enclosed volumes and can be secured to each other by a first bayonet connection, a first door and a second door (11) which close off the passage openings and can be secured to each other by a second bayonet connection, the first door (11) being hingedly mounted on the first flange (10) by means of a hinge (4) comprising a hinge pin, characterized in that the device comprises an external manual control lever (9) which is secured to a rotary pin penetrating the first flange (10) and which is coupled to the hinge pin in such a way that the actuation of the control lever (9) drives the hinge pin, thus opening or closing the first door (11).

A treatment apparatus for treating biological cell cultures, located in respective storage chambers of a carrier, includes a work deck with one or more bearing spots for bearing the carrier. Each of the bearing spots includes a bearing region corresponding to an area of the carrier. The treatment apparatus additionally includes nozzles for producing a gas flow in a space above the work deck. To avoid liquid droplets or cell material being transported from one storage chamber to another as a result of a horizontal gas flow above the carrier during the treatment, the nozzles are arranged outside of and along an edge of the bearing region or within the bearing region and form a gas curtain around the carrier or the respective storage chambers.
