Abstract:
A pipetting apparatus includes a pipetting head with a plurality of pipetting channels disposed in an arrangement pattern. Each pipetting channel includes a plunger and a cylinder. The plurality of pipetting channels includes at least two groups of pipetting channels with different diameters including a group of larger pipetting channels and a group of smaller pipetting channels. Each of the at least two groups of pipetting channels is disposed in an arrangement pattern in the pipetting head. Larger pipette tips communicate with the group of larger pipetting channels or smaller pipette tips communicate with the group of smaller pipetting channels.

Abstract:
A cold box having a cooling receptacle filled with a dry protective gas in which is accommodated a rack loaded with tube-shaped vessels. The cooling receptacle is covered by a movable lid which is associated with a lid part and which is preferably formed by an outer lid and a rotatable inner lid integrated in the outer lid so that the cooling receptacle is completely covered in every position of the lid. At least one of the through-holes provided in the inner lid can be arranged over a respective tube-shaped vessel by a coordinated movement of the outer lid and rotation of the inner lid so that the tube-shaped vessel located under the through-hole in alignment therewith can be filled with a sample through the through-hole by means of a commercially available pipette tip/dispensing needle of an automated pipetting device.
