A pipetting device (2) for removing fluid from a sample vessel (52) includes a pipetting needle (4) and an auxiliary cannula (18) for piercing a septum, designed to guide the pipetting needle axially through the auxiliary cannula. The pipetting device has a guide arm (6), on the lower end (10) of which is arranged an end plate (12) that is axially displaceable along the guide arm against a resilient resistance. A centering device (14) inserts into the end plate of the guide arm, and at least three centering fingers (26) with conical bevels (34) are constructed on the radial outside of the centering device, distributed around the circumference thereof, and forming a holding-down device for the sample vessel. The disclosed construction makes possible to reliably pierce the septum of a sample vessel and to easily pull the pipetting needle out of the septum again even with thin pipetting needles.

Particles are dispensed under controlled conditions to achieve an accurate number of particles by passing a suspension of the particles through a particle detecting device, obtaining a cumulative particle count, comparing the cumulative particle count with a target value, and shutting off the suspension flow once the particle count reaches the target value, all performed by automated means.

The present invention relates to an apparatus for sample taking from a fluid-conducting system, wherein the apparatus has at least one adapter which comprises at least one septum and at least one cannula displaceable relative to the septum, wherein the cannula is displaceable such that it penetrates the septum in a sample taking position and does not penetrate the septum in a flushing position; and wherein the adapter has at least one flushing region for a flushing medium which is arranged such that it is in fluid communication with the inner space of the cannula in the flushing position of the cannula; and wherein the apparatus has at least one receiving region having locking means for the fluid-conducting system by which the fluid-conducting system is fixable in a defined position relative to the adapter. The present invention furthermore relates to a blood treatment device and to a method for taking a sample from a fluid-conducting system.

The present invention is such a plug application and removal device that mist which is generated upon plug removal of a sample container or a reagent container is not peripherally scattered, or is such a sample processing device that mist which is generated upon dispensing of a sample or a reagent into a container is not mixed to another container. A plug application and removal device has a container holding mechanism that holds a container housing liquid inside and applied with a plug, and has a plug application and removal mechanism that removes or applies the plug from/to the container. The plug application and removal device has: a control mechanism for controlling movement of liquid or mist spilled out of the container upon a process of removal or application of the plug by the plug application and removal mechanism.

A quantitative sample transfer device for receiving and holding a sample while it is weighed and for transferring the weighed sample material into a flask without losing any sample, the quantitative sample transfer device having a hollow central body segment with a flat bottom surface, a first hollow neck at one end of the central body, a second hollow neck at the opposite end of the central body, a removable first cap for occluding the first hollow neck, a removable second cap for occluding the second hollow neck, an opening in the central body for introducing a sample into the body, a lid permanently attachable to the body segment over the opening that remains permanently closed once closed and a set of lateral ridges on at least one neck that allow for the release of air when a solvent is introduced into the transfer device to flush any remaining sample into the container. The lid may be hinged to the body segment.

Provided is a novel particle adsorption probe (1000) for picking up a particle by adsorbing the particle. The particle adsorption probe (1000) can selectively pick up a particle having a specific particle diameter from a group of particles having a wide particle diameter distribution without requiring the application of a physical stress in picking up the particle and without contaminating a foreign matter surface in picking up the particle, and allows the particle to be analytically evaluated in an analysis apparatus directly after picking up the particle. The particle adsorption probe (1000) of the present invention includes a carbon nanotube aggregate (100) including a plurality of carbon nanotubes (10).

A material mixing cartridge for a dispensing system comprises a dispensing chamber, with a material dispensing outlet and a dispensing actuator for dispensing material through the material dispensing outlet. The mixing cartridge further comprises at least two material compartments for receiving material to be mixed, and at least one material transfer channel which is adapted for material transfer between the at least two material compartments and the dispensing chamber The mixing cartridge further comprises at least one valve arranged to regulate material flow between a material compartment and the dispensing chamber via the at least one material transfer channel.

A dosing set including a container and a dosing apparatus. The container can hold a reagent and be driven to rotate. The dosing apparatus includes a first channel and at least one first spiral rod. The first channel has a first channel first opening connecting with the container to allow the reagent inside the container to enter the first channel, and a first channel second opening connecting with outside of the first channel to allow the reagent to leave the first channel. The first spiral rod is within the first channel and can be driven to rotate in a first direction, to deliver the reagent from the first channel to the first channel second opening, and to control a mass flow rate of the reagent leaving through the first channel second opening by adjusting the rotational speed of itself.
