Abstract:
Methods, devices, and systems are disclosed for collecting or gathering samples, such as zebrafish or zebrafish eggs or embryos, dispersed in a liquid and transferring the collected or gathered samples into discrete receptacles of a holding fixture (e.g. the wells of a multi-well plate, a Petri dish, or any other suitable fixture having one or more receptacles). A method includes drawing some of the liquid through a plurality of openings in a retention structure so as to draw at least some of the samples into contact with associated openings, retaining the samples in contact with the retention structure adjacent to the associated openings using differential pressure, moving at least one of the retention structure or a holding fixture relative to the other while the samples are retained adjacent the associated openings, and ejecting samples from the retention structure into associated discrete receptacles of the holding fixture.
Abstract:
The tube assembly of the present disclosure includes a first tube, a second tube, a mechanism for securing the tubes, and a means of applying a seal material to first end of second tube. The first end of the second tube extends beyond the first end of the first tube an interstitial space is created between the outer diameter of the first tube and the inner diameter of the second tube. The tubing mechanism is utilized for retrieval of a biological fluid through the first tube, flushing the first tube and the second tube with a rinse solution during the return of biological fluid.
Abstract:
Die Erfindung betrifft einen Schrank, insbesondere Sicherheitsschrank oder Gefahrstoffschrank, zur Lagerung von vorzugsweise flüssigen Gefahrstoffen, mit einem Schrankkorpus (7) und wenigstens einer den Schrankkorpus (7) verschließenden Schranktür (8). Die Erfindung ist dadurch gekennzeichnet, dass, eine Zugangskontrolleinheit (10) vorgesehen ist, welche nach einer positiven Zugangskontrollprüfung nicht nur die Schranktür (8) öffnet, sondern auch eine im Inneren des Schrankkorpus (7) angeordnete Medienabgabeeinheit (4) freigibt.
Abstract:
A vapour generator system (1, 101) for an IMS (4, 104) or other apparatus has a chamber (9, 109) in which vapour is produced. A fan or other flow generator (6, 106) is connected to an inlet (8, 108) of the vapour chamber (9, 109) and its outlet (13, 113) is connected to an adsorbent passage (14, 114), such as formed by a bore through a block (15) of carbon. When the fan (6, 106) is on gas flows through the vapour chamber (9, 109) and the adsorbent passage (14, 114) to the IMS (4, 104) or other outlet, with little vapour being adsorbed in the passage. When the fan (6, 106) is off, any vapour molecules that escape to the adsorbent passage (14, 114) do so at a low rate such that substantially all is adsorbed and no vapour escapes.
Abstract:
Eine Laborsubstanz-Behältereinheit zur Lagerung und zum Schutz von Laborsubstanzen umfasst ein Schutzgehäuse und mindestens eine Dosiereinheit. Die mindestens eine Dosiereinheit weist einen Vorratsbehälter und einen Dosierkopf auf. Zur Erstellung der Betriebsbereitschaft der mindestens einen Dosiereinheit ist das Schutzgehäuse von der Dosiereinheit entfernbar. Das Schutzgehäuse weist ein Unterteil mit mindestens einer passend geformten Ausnehmung zur lagestabilen Aufnahme der mindestens einen Dosiereinheit, sowie ein haubenförmiges Oberteil auf. Das Oberteil ist zur Bildung eines gasdichten Innenraums mit dem Unterteil verbindbar. Die mindestens eine Dosiereinheit ist zu Transport- und Lagerungszwecken im Innenraum des verschlossenen Schutzgehäuses angeordnet.
Abstract:
A syringe-like device (hereinafter "syringe") that is operable by a single hand, wherein the syringe includes a plunger for ejecting and then retracting a fiber or filament used for the collection of solids, solids in suspensions and liquids, wherein the syringe includes a microchip embedded in the syringe housing, and wherein the microchip enables electronic chain of custody tracking of a sample from a point of origin through final analysis.
Abstract:
An improved system and method for dispensing dehydrated culture media (DCM) powder into containers for preparation as a culture media. The manual and automated systems and methods operate to dispense DCM powder, as well as liquid, into vessels or media preparation instruments in a manner to avoid DCM dust inhalation by persons in the surrounding area and contamination of equipment and surfaces in the surrounding area. The system can further comprise a carousel arrangement that permits dispensing of DCM powder from multiple containers at multiple volumes and rates. Ia addition, the containers have a particular configuration for use with the system and method, such as the carousel arrangement, to avoid errors, promote repeatability and eliminate dusting. The containers can also include a device, such as an auger, to facilitated measured dispensing of the DCM powder automatically or manually into a flask, automated media sterilizers or other instruments.
