An improved biological sample preparation device and method of using the device. The disclosed device provides improved sample volume control, reduces potential contamination in the working environment, increases ease of use, and improves safety for healthcare workers.

A pipetting device for taking up and dispensing fluid volumes has a displacement device with a displacement mechanism and a displacement housing. The pipetting device has an adjusting device for changing the stroke of the displacement mechanism. The stroke of the displacement mechanism can be adjusted, and the corresponding adjustment value can be displayed by an adjustment indicator. A coupling device, in a use state, couples the adjusting device to a volume indicator and decoupled the adjustment device from the adjustment indicator. In an adjustment state, the adjusting device is coupled to the adjustment indicator and is decoupled from the volume indicator. The adjustment indicator displays an adjustment value for the stroke of the displacement means. The adjustment indicator can be adjusted in an adjustment state, whereas it is fixed in a use state.

The present disclosure relates to a medical diagnostic system. In various embodiments, the system includes a housing, a first receptacle in the housing for receiving a reagent container, a second receptacle in the housing for receiving a working fluid and waste container, where the second receptacle is larger than the first receptacle, two reagent access needles positioned and fixed within the first receptacle with each of the two reagent access needles being substantially horizontal to horizontally access the reagent container, and a working fluid access needle and a waste access needle positioned and fixed within the second receptacle with the working fluid access needle and the waste access needle being substantially horizontal to horizontally access the working fluid and waste container.

A system and method of fluid delivery for providing a surface fluid pattern. The system includes a fluid delivery head for fluid flow therethrough. The fluid delivery head includes a fluid delivery surface having surface openings defined therein and arranged across the fluid delivery surface as a two-dimensional display. Some of the surface openings are grouped as a surface opening unit. The surface opening unit includes at least one aspiration opening through which fluid can be provided to the fluid delivery surface and at least one injection opening through which fluid can be moved away from the fluid delivery surface. The surface opening unit includes at least three surface openings positioned as a two-dimensional display and outwardly of at least one other surface opening.

A solid transferring device includes a main body and a lance. The main body comprises a casing, a power system, a weighing system including a weight sensor and a control system. The power system comprises a motor and a transmission shaft having a transmission shaft head for matching a lance transmission head. The lance includes the lance shell, a screw and the lance transmission head, and an upper part of the lance shell has a matching engaging portion for matching the tip portion of the sleeve to allow the main body to catch the lance. The motor is configured to control the transmission shaft to rotate forwardly or reversely, that when the transmission shaft head is inserted into the lance, drives the screw to rotate forwardly or reversely to screw in to take a solid sample or screw out to release the solid sample.

According to aspects of the present disclosure, a seat of an exercise bench may be repositioned (e.g., raised and rotated) to function as an elbow or arm rest for various weightlifting exercises (referred to as the “deployed position”). The repositioning of the seat (or arm rest) is achieved with a pivot stopping mechanism that securely limit the desired reposition angle and location during adjustment.

Embodiments of lab automation workstations are disclosed in which the pod that performs pipetting operations is integrated with pipette tip-loading functionality. To generate the necessary tip-loading force, a dual drive system is used that is symmetric about the Y-axis to allow for offset or partial tip box loads by dynamically centering the drive force (e.g., the tip-loading force) over the reaction load. This minimizes the need for oversized linear motion components while still allowing for the generation of high tip-loading forces needed to properly load a large number of pipette tips simultaneously.

A microfluidic device for non-invasively and passively accessing interstitial fluid from a patient includes a substrate containing multiple vertical micro channels therethrough, wherein at a first end of each of the multiple vertical micro channels a microheater is formed for controllably ablating a portion of dry dead skin cells to access the interstitial fluid; and wherein at a second end of each of the multiple vertical micro channels is a horizontal micro channel for receiving accessed interstitial fluid from a vertical micro channel and guiding the accessed interstitial fluid to a common collection port.
