An actuated, height adjustable optical table or workstation for use in microscopy, optical research laboratories and similar environments includes fixed and moving parts which combine to create a rigid, height adjustable table structure on which to mount an optical breadboard or similar platforms via optional passive or active vibration isolation mounts. The height adjustment is performed by multiple compact actuators with associated control hardware and software, and allows the user or an application system to perform activities with the table at any heights.

A pipetting device (1) for receiving and dispensing fluid volumes, comprising a housing (2) with a holding portion (3), which is constructed for holding the pipetting device (1) by means of an operator's hand, a support device (4), which is designed for supporting the pipetting device (1) on an operator's finger, the support device (4) being rotatable relative to the holding portion (3), preferably about a longitudinal axis (L) of the pipetting device (1). The invention further relates to a pipetting device (1) for receiving and dispensing fluid volumes, comprising a releasable positive connection between a first and a second component of the pipetting device (1). Because the support device is adjustable relative to the holding device into a plurality of different defined rotational positions the pipetting device can be used by either left-handed and right-handed operators or by operators with hands of different sizes.

Described herein is a contact plate for microbial testing and sampling of corner surfaces. The contact plate may comprise a base having a first side and a second side. The first side may have a first wall and a second wall extending outward from the first side of the base to form a corner and define a surface for collecting biological samples. Additionally, the contact plate may include a rectangular lid configured to secure around the first wall and the second wall, and/or a handle removably coupled to the second side of the base.

An electronic pipette comprising a piston actuated in a cylinder by a motor, a control system for carrying out pipette operations, and a user interface for operating the pipette, which user interface comprises a display, wherein the main menu of the user interface comprises a user defined shortcut to a specific pipetting application.

The manual dosing device (1) comprises the main body (3) that can be screwed to the fluid discharge unit (4), the detent connection (10) being provided alongside the screw connection (6) for removably connecting the main body (3) to the fluid discharge unit (4), which detent connection is locked by connecting the main body (3) and the fluid discharge unit (4) together (cf. FIG. 5).

Provided herein are containers for holding a portion of a biological sample such as a fecal sample. The containers include a body that can be sealed with an upper cap that is attached to a sampling pin and a grip member. The sampling pin is configured to collect a predetermined amount of sample in one or more sampling grooves, with excess sample amount optionally removed from the sampling pin by an interior flange of the container body. The grip member is configured to provide the user of the container with improved torque and grip, and to distance the fingers of the user from the sample being collected. Also provided are kits and methods including the disclosed containers.

An automated laboratory system includes a vertical shelving system including a frame and at least one shelf movably mounted to the frame such that the at least one shelf is movable relative to the frame between a docked position and an undocked position, the at least one shelf being configured to carry at least one instrument. The system also includes a robotic device proximate the vertical shelving system and being configured to access the at least one instrument carried by the at least one shelf.

A multiple-antenna positioning system with a single drive element, providing reduced weight and complexity over systems that have a drive element for each antenna. In certain examples, each antenna can be coupled with a rotating spindle, with each antenna spindle being coupled with a pair of link arms. By driving a single drive spindle, each of the antenna spindles in the system can be rotated by the associated pair of link arms. The link arms can have an adjustable length, such as through a turnbuckle mechanism, to reduce backlash in the system, and in some examples can apply a preload to the system. By reducing backlash, the multiple antenna positioning system can have improved responsiveness to a rotation of the single drive element, as well as improved stability of the positioning of each antenna when the drive element is held in a fixed position.

Provided herein are pipette tips having a proximal region with grooves and panels configured to facilitate wall expansion or wall compression when a pipette tip is mounted onto and sealingly engages with an appropriately designed liquid dispensing device.

Disclosed is a test barrel, to prevent a test liquid in the barrel from sputtering into a connection gap due to shaking of the barrel to hence cause contamination, improve the measurement accuracy in case of multiple tests, and meanwhile improve the operability of screwing on and screwing off the entire device during use of the device. The above technical objective of this utility model is implemented by employing the following technical solution: a test barrel, comprising barrel lid and a barrel body; wherein the threaded rings are arranged on an inner wall of a side face of the barrel lid and an outer wall of an opening of the barrel body, a rotary force applying portion is arranged on an outer wall of the side face of the barrel lid, and during engagement, a liquid blocking washer is arranged between the barrel lid and the barrel body, wherein a radial width of the liquid blocking washer is greater than a thickness of the opening of the barrel body.
