An apparatus for collecting and storing fluid samples from vehicles and machinery comprises a storage container having a fluid inlet sealed by a cap, the cap having an aperture releasably sealed by a lid. An adapter connects the cap releasably to a fluid outlet coupling port of a fluid sampling device. The adapter comprises a lumen, having an inlet and an outlet aperture, an external screw thread engageable with an internal screw thread of the coupling port and a connector assembly for connecting the adapter releasably to the cap. A penetrable diaphragm provides an airtight seal over a storage region of the storage container. When the adapter is connected to the coupling port and the cap is connected to the adapter, a fluid outlet tube extending from the coupling port extends through the aperture and protrudes through one or more perforations provided in the penetrable diaphragm into the storage region.

Provided is a temperature control system applied to an apparatus for analyzing a sample using a pipette nozzle and a reaction container, including a pipette tip temperature controller that heats a pipette tip which is fitted on the pipette nozzle and aspirates or discharges liquid and a reaction container temperature controller that heats the reaction container. The pipette tip temperature controller heats, in a concentrated manner, at least a distal end portion of the pipette tip of the pipette nozzle located at a predetermined heating position with hot air emitted from a heat source and is configured such that a distal end is capable of arriving at the reaction container by lowering the pipette nozzle from the heating position.

A method and system for processing an adipose tissue material sample to create and collect fat aspirate particles having particle diameters less than or equal to a selected size are disclosed. A filter screen assembly having an interface part, a closed end opposite to the interface part, and a screen portion therebetween is inserted through a first port in a lid of a container, with the interface part providing access to an interior of the container for insertion of a transfer cannula connected to a syringe filled with the adipose tissue material. The screen portion includes a plurality of apertures having diameters of the selected size. Adipose tissue material is expelled from the transfer cannula through the apertures of the filter screen assembly into the container to create and collect the fat aspirate particles having particle diameters less than or equal to the selected size.

An apparatus, system, and method for filtering and assaying a fluid sample are described. In an embodiment, the apparatus includes a filtration unit comprising: a filter bracket shaped to removably couple with a fluid sample cup and a vacuum container; and a filter housing cooperatively couplable to the filter bracket and comprising a filter configured to filter fluid passing through the filter bracket; and an assay device shaped to cooperatively couple with the filter housing and comprising a porous matrix positioned to be in fluidic communication with the filter when the filter housing is cooperatively coupled with the assay device.

A blood cell analysis method and a blood cell analyzer are provided. In the method and analyzer, characteristic information of white blood cell fragments is obtained based on side scattered light information and fluorescence information, characteristic information of platelets is obtained based on forward scattered light information and fluorescence information and then a count value for the platelets is acquired based on the characteristic information of the platelets and the characteristic information of the white blood cell fragments. The present invention can avoid the influence of the white blood cell fragments on the platelet counting, thereby ensuring the accuracy of the platelet counting without increasing costs.

A dispensing cylinder capable of performing a dispensing treatment for both minute and large amounts of liquid includes: a cylinder having a cavity; a nozzle provided at one end of the cylinder, having a through hole in fluid communication with the cavity and extending in an axial direction of the cavity, and a plunger slidable in the cavity in the axial direction. The cavity has a large diameter region having a large inner peripheral surface and a small diameter region having a second inner peripheral surface. The plunger has a thick shaft portion slidable in the large diameter region and a thin shaft portion protruding from a distal end of the thick shaft portion in the axial direction and slidable in the small diameter region.

Apparatus and method for detecting a dissolved gaseous impurity in an aqueous environment, comprises a tube for isolating liquid surface, or a sampler for obtaining a liquid sample from the aqueous environment, a vacuum pump located to exert a vacuum, leaving the surface to evaporate into the vacuum; and a holding compartment for holding evaporated gas which may then be analyzed using electrochemical or spectroscopic methods. The apparatus is useful for detecting levels of ammonia in fish ponds or indeed any impurity that may be dissolved in the water.

In this invention it is disclosed a remote-controlled vehicle for operations in the extreme conditions (10) which comprises a base vehicle (100), a gripper (200), a manipulator arm (300), a mission module wherein base vehicle comprises front (110) and rear part (120), wherein on the front part of the base vehicle gripper is mounted and on the rear part of the base vehicle the manipulator arm is mounted and when in operation, the gripper and the manipulator arm are remotely operated. Also, it is disclosed whole system for remote operations comprising said remote-controlled vehicle and a control centre comprising a set of graphical user interfaces (GUI) and video displays (VD) arranged so that two way communication between the vehicle and control centre is established and wherein from GUI person can control and operate with the vehicle.

A leak monitoring manifold is provided to detect and regulate sample leaks in a pump system. The manifold may include a fluid inflow location and a relief valve including a relief outlet which is in fluid communication with the fluid inflow location. The relief valve may operate to be in either of a first state or a second state. In the first state fluid flow out of the relief outlet is blocked, and in the second state fluid flow is open between the fluid inflow location and the relief outlet. The relief valve may alternate between the first state and the second state when a pressure acting on the relief valve reaches a preconfigured pressure set point.
