The present invention relates generally to an apparatus for identifying biological particles. More particularly, the present invention relates to a small apparatus for identifying biological particles, wherein in a single apparatus having a simple structure, a cleaning solution is suctioned to separate the biological particles from a filter and a sample solution is discharged, the discharged sample solution is injected into a plurality of ticket modules, and the biological particles are identified by image analysis for the ticket modules, thereby enabling miniaturization of the apparatus.

A fluid sampling device including an inlet configured to receive a portion of a non-homogeneous fluid flowing through a conduit, a first double block bleed valve coupled to the inlet, a first flexible hose coupled to the first double block bleed valve by a first quick acting and leakage free coupling, a collection drum coupled to the first flexible hose by a first control valve, and a container coupled to the connection drum by a manual valve, wherein the device is configured to collect a fluid sample in the container. The device also includes a pressure controller to control pressure within the collection drum, and a level indicator to indicate a level of fluid in the collection drum.

An elemental analysis device includes a heating furnace in which a test sample that is placed in a crucible is heated so that a sample gas is generated from the test sample, an inflow path through which a carrier gas is introduced into the heating furnace, an outflow path through which a mixture gas made up of the carrier gas and the sample gas is led out from the heating furnace, a dust filter that is provided on the outflow path, an analysis mechanism that is provided on the outflow path on a downstream side from the dust filter, and that detects one or a plurality of predetermined components contained in the mixture gas, and a cleaning gas supply mechanism that supplies cleaning gas to the dust filter in an opposite direction from a direction in which the mixture gas is flowing.

A biological sample reaction vessel comprising a reagent storage portion and a push rod movable relative to the reagent storage portion is provided. The reagent storage portion comprises at least one reagent containing cavity, and the reagent containing cavity is sealed by a sealing element; and the push rod is connected to the sealing element, and the push rod is used for cooperation with an external device to separate the sealing element from the reagent storage portion. In reaction, the biological sample reaction vessel cooperates with a test cassette. By inserting the biological sample reaction vessel into the external device, the reagent in the reagent storage portion can be released rapidly.

A pipette has a first chamber and a second chamber that connects to the first chamber and extends with an outlet channel to a pipette tip. The chambers are separated from one another by a longitudinally displaceable piston having a piston non-return valve. The second chamber has a chamber non-return valve which is arranged upstream of the outlet channel. An associated method includes recirculating the liquid in the first chamber, filling the first chamber with the liquid via a direct feed line, filling the second chamber with the liquid from the first chamber by pulling back the piston in the filling position toward the first chamber with the piston non-return valve open and with the chamber non-return valve closed, and emptying the second chamber by advancing the piston in the emptying position towards the outlet channel, with the piston non-return valve closed and the chamber non-return valve open.
