The present invention provides a rotary evaporator capable of accurately quantifying concentrated liquid and/or distillate. A distillation flask is improved into a structure having a liquid discharge opening formed at the bottom, and/or a spherical collecting flask is improved into a structure having a liquid release opening formed at the bottom. Concentrated liquid and/or distillate can be discharged without dismounting the distillation flask and/or the collecting flask. In addition, fine metering scale tubes and quantitative capacity increase units are disposed at the liquid discharge opening and/or the liquid release opening, there is a valve on the top and another valve on the bottom of each tube, so that the constant subtle changes of the amount of concentrated liquid and/or distillate can be observed, and an accurate amount of concentrated liquid and/or distillate can be discharged.

The present invention relates to a method and a system (400) for filling a closed container (200) with a fixative solution. The system comprises a container (200) comprising a container body (230) for receiving a biological specimen, a lid (220) for selectively closing the container body (230) and a port (100) forming a unidirectional barrier in a direction from the inside (IC) to the outside (OC) of the closed container (200). The system further comprises a dispensing apparatus (500) having a filling nozzle (300) for dispensing the fixative solution. The filling nozzle (300) is relatively moveable with respect to the container (200) between a retracted position and a filling position to fill the container (200) with the fixative solution.

The methods and systems of the invention include the use of automated solution dispensers in laboratory environment. The automated solution dispensers can be controlled locally or remotely within a network. The usage of the instruments can be followed and procurement of supplies can be automated.

Aspects of the present disclosure are directed to a method and a device for carrying out chemical, biochemical and/or immunochemical analyses of liquid samples, which are present in a sample store of an automatic analyzer, with the aid of liquid reagents, which are present in at least one reagent store of the analyzer. In one embodiment, a analyzer is disclosed including cuvettes for holding the liquid samples and reagents, the cuvettes are arranged in at least one stationary, linear cuvette array. The analyzer further has an optical measurement unit with a stationary light-supplying unit which has at least one light distributor device that feeds the light from a plurality of LED light sources emitting in a spectrally different manner in the UV/VIS/NIR wavelength range into the inlet windows of the individual cuvettes of the cuvette array. The optical measurement unit further includes a stationary detection unit assigned to outlet windows of the cuvettes and further includes a plurality of photodiodes.

The present invention relates to an immunoassay apparatus and a method thereof. The immunoassay apparatus including a cartridge 13 in which a tube for T tip 9, a reaction tube 11, a tube for washing 3, and a tube for signal measurement 5 are integrally coupled or individually configured; a T tip 7 and a magnetic rod 31 used for performing reaction and washing processes while moving large magnetic particles m, capture materials, signal materials, and analyte materials with magnetic force by entering successively a plurality of tubes 3 and 5; a cartridge holder 15 in which the cartridge 13 is seated; and a heating member 17 that generates heat by being disposed at a region in which the reaction tube 11 is seated in the cartridge holder 15; is configured in a state where each of the different shapes of magnetic particles is bound with materials.

The present invention relates to a biological material extraction apparatus. According to the present invention, a tube in which a solution for use in extracting a biological material is contained is rotated to directly mix the solution, and cells where stirring is being conducted in each step are sealed to fundamentally block stirring-induced pollution between cells, thereby improving an extraction efficiency.

Examples disclosed herein relate to a device. Examples devices include a dispense routine engine to determine a first dispense routine for a first compound in a first chamber and a second compound in a second chamber. The dispense routine engine to determine a second dispense routine for the first compound and the second compound in response to a cancel chamber request for the second chamber and a chamber designation request for the second compound in a third chamber. Example devices include a dispense engine to control the dispense device to cancel dispensing of the second compound from the second chamber and to dispense at least a portion of the first compound from the first chamber and at least a portion of the second compound from the third chamber according to the second dispense routine.

Embodiments of the system and/or method can include and/or apply a magnetic device for facilitating a magnetic field for isolating the nucleic acid material from a sample, the magnetic device including a support component; and a set of magnetic pins attached to the support component and movable with at least three degrees of freedom when attached to the support component, where the set of magnetic pins provide adaptability to shapes of sample compartments of a sample container.
