The invention relates to a pipetting device having an exchangeable pipette tip for suctioning and discharging fluid volumes for use in automated laboratory systems. The invention relates to a pipetting device having a pipette tip detection unit and for detecting a pipette tip on a pipette device of this type. A detection unit detects whether a pipette tip is connected to the pipette tube or determines a characteristic feature of the connected pipette tip. The pipette tip forms at least one portion of a first electrode when the pipette tip is in electrical operative contact with the pipette tube and, e.g., a pipette tip holder, a contact for setting down the pipette tip holder or a working table over which the pipette tube can be moved forms at least one portion of a second electrode.

An apparatus for collecting a sample fluid includes a base part with sample well plate with cavity having plurality of holes fluidically connecting first side and second side of cavity. The cavity is configured to accommodate sample collection part of sample stick on first side of cavity. The base part has microfluidic plate configured to channelize flow of at least a part of sample fluid received via plurality of holes towards at least one sensor coupled to microfluidic plate; and plurality of electrical connectors connected to at least one sensor. Moreover, the apparatus has lid part coupled to base part, lid part having compressible region configured to receive first amount of external force thereon and exert pressure over sample collection part to enable flow of sample fluid towards at least one sensor.

A pipetting device having a lube has an opening al one end for suclioning or discharging a sample fluid and can be operatively connected to a pressure generation device at the other end, a first electrode is formed on the pipetting device and forms a measuring capacitor together with a second electrode formed by at least one part of the sample fluid that can be received in the tube and that measuring capacitor is operatively connected to a measuring unit, and the measuring unit is designed to determine a volume of the suctioned or discharged sample fluid according to the capacity of the measuring capacitor, as well as having a first electrical contact that is designed to create an electrical connection with the working fluid, the first electrical contact can be electrically connected to the measuring unit via a low-rcsistancc converter circuit.

A PCR tube holder comprises an elongated strip body having a first portion and a second portion. One or more holes are defined in the first portion of the elongated strip body, the at least one hole configured to receive a single PCR tube. A writable zone in the second portion of the elongated strip body, the writable zone configured to receive ink thereon. A material of the elongated strip body is adapted to retain the ink through a PCR cycle. The material of the elongated strip body has a minimum flexural rigidity such that the elongated strip is adapted to support a PCR tube without folding.

The present invention relates to pipette tips for connecting to a pipette tube of a pipetting device that is used for taking up and dispensing fluids. A pipette tip is shaped as a long tube that forms a pipette body with an opening on one of its ends and the other end is designed to connect to the pipette tube. The pipette tip is characterised in that it has an electrode as a volume measuring electrode of a measuring capacitor. The present invention further relates to pipetting devices with a pipette tip, methods for determining the volume of a fluid sample in such a pipette tip, methods for recognising such a pipette tip on a pipetting device, methods for producing such a pipette tip, uses for such a pipette tip and a set of pipette tips.

The invention features devices, systems, and methods for introducing a sample (e.g., a biological sample, e.g., a blood sample) into a reaction vessel to maximize the effectiveness and/or reproducibility of introducing the sample (e.g., a biological sample, e.g., a blood sample).

A system for performing a molecular analysis workflow includes a reaction holder or a reaction substrate, such as a multi-well reaction plate, with a reaction holder/substrate RFID tag, and/or a reagent container with a reagent container RFID tag, and an instrument and/or device that includes an RFID reader/writer operable to read and/or write information to and from the reaction holder/substrate RFID tag and/or the reagent container RFID tag. The reaction holder/substrate RFID tag and the reagent container RFID tag can be utilized separately or together to send and receive and store information, for example, for a workflow of a molecular analysis, such as a polymerase chain reaction (PCR).

A test device is configured for diagnostic testing and includes an optical readable medium, in turn including a pattern of spots of material arranged on a surface of the device. Several patterns may be provided. The patterns accordingly formed may be human and/or machine readable. They may notably encode security information, e.g., indicating whether the device has already been used. The spots may notably be inkjet spotted. In addition, a method is provided for decoding information encoded in a pattern of such a test device. In embodiments, liquid is introduced in the device, which comprises additional spots having a substantially different solubility than spots forming the actual pattern. Thus, the additional spots get solubilized in and flushed by the liquid as the latter wets them, and an initially hidden pattern may be read, which is formed of the remaining spots (not solubilized). Encoding methods are also provided.

Systems and methods for detecting and/or identifying target cells (e.g., bacteria) using engineered transduction particles are described herein. In some embodiments, a method includes mixing a quantity of transduction particles within a sample. The transduction particles are associated with a target cell. The transduction particles are non-replicative, and are engineered to include a nucleic acid molecule formulated to cause the target cell to produce a series of reporter molecules. The sample and the transduction particles are maintained to express the series of the reporter molecules when target cell is present in the sample. A signal associated with a quantity of the reporter molecules is received. In some embodiments, a magnitude of the signal is independent from a quantity of the transduction particle above a predetermined quantity.
