A laboratory pipette stand for use with single channel and multi-channel pipettes in a laboratory environment is disclosed. The laboratory stand includes a unitary structure having an angular longitudinal planar body and a supporting base portion. A first tier of a plurality of outwardly projecting pronged sections having a plurality of concave sections therebetween is formed at an upper portion of the unitary structure. A second tier of a plurality of outwardly projecting pronged sections having a plurality of concave sections therebetween is formed at a middle portion of the unitary structure. The first and second tiers are configured for holding a plurality of single channel and multi-channel laboratory pipettes thereto. At least one elongated opening is formed in the angular longitudinal planar body from the middle portion to a lower portion of the unitary structure such that the at least one elongated opening is configured for receiving a manifold of the multi-channel laboratory pipette therethrough.

The invention relates to a pipette auxiliary system for supporting manual pipetting or dispensing of a plurality of samples of a sample-holding arrangement, in particular a microtiter plate. The pipette auxiliary system according to the invention supports the manual pipetting or dispensing of a plurality of samples in a working position of a sample-holding arrangement, the pipette auxiliary system comprising: a base apparatus comprising a positioning device which is designed to position the sample-holding arrangement in the working position inside a positioning space of the base apparatus, said positioning space being opened at least along a plane for the pipetting; the sample-holding arrangement which has a plurality of sample holders; a measurement arrangement comprising a plurality of measurement elements which are positioned at least in the working position underneath this plane and using which the occupancy state of at least one sample holder can be detected in the working position; and an output device or a light arrangement using which the sample-holding arrangement can be illuminated in accordance with this occupancy state of this at least one sample holder.

A specimen container holding apparatus is disclosed. The apparatus is configured to hold a container for receiving liquids from a bronchoscope. The apparatus includes a needle guide with a first and a second opening configured to receive a needle of the bronchoscope. The first and second opening may be disposed on a removable tip of the needle guide. The removable tip may be detachably connected to a removable tip connection point. The apparatus may further include a slide holder configured to hold a slide.

The present invention provides a sample extraction device, comprising an extraction table and an operating and moving module. The operating and moving module comprises a first horizontal movement module, a first vertical movement module, and a suction module. The suction module is provided on a supporting frame of the first horizontal movement module, and comprises a second vertical movement module and an injector, the second vertical movement module is configured to move vertically with respect to the extraction table, the injector has an airtight cylinder and a piston rod, and the airtight cylinder is connected to the gas delivery tube; wherein the second vertical movement module moves vertically to push or pull the airtight cylinder or the piston rod, in order for the injector to generate positive or negative pressure. The sample extraction device of the present invention can reduce the space required for operation substantially.

The invention relates to a holding apparatus for holding a pipetting container, in particular a serological pipette, at a pipetting apparatus, comprising a tubular connecting section that is configured to hold the tube-shaped end of a pipetting container in a pipetting position by means of a clamping connection, a clamping connection device that is arranged at the connecting section and that comprises a spring device for the establishment of the clamping connection and an air chamber device for releasing the clamping connection by means of a vacuum. Furthermore, the invention relates to a pipetting apparatus with that holding apparatus.
