Abstract:
Sampling vessel, to be used preferably with automated sampling apparatuses with moving sampling head for sampling a flowing substance stream, wherein the sampling vessel comprises a body (12), an inlet (14) and an outlet (16) formed on the body (12), a channel (13) defining a continuous flow path extending between the inlet (14) and the outlet (16), as well as a sampling opening to perform sampling by the sampling needle, wherein the sampling opening communicates with the channel (13) and is sealed in a gastight manner by a closing means (24) penetrable for the sampling needle. In the sampling vessel, a sampling segment (17) is formed in the channel (13), the sampling opening communicates with the sampling segment (17) through a needle guiding channel (15), and the inlet (14) and the outlet (16) are arranged so as to provide a substance flow in said sampling segment (17) towards the sampling opening.
Abstract:
The present invention relates to a sample holder vessel (10), in particular for sampling operations to be performed by an automated sample feeder apparatus having a sampling needle. Said sample holder vessel has a body (11) defining an internal space and comprising a top portion and a lower section. The body is further provided with a first sampling port (12) with a geometric axis at the top portion and a second sampling port (14) in the lower section, said sampling ports being adapted for receiving closing elements (13, 15) that can be detachably connected with the sampling ports, enable more than one successive sampling operations from predetermined regions of the internal space and also close the internal space of the sample holder vessel in a leakproof manner. Moreover, the geometric axis of the first sampling port extends substantially parallel to the sampling needle when a sampling operation from the sample holder vessel is performed with said sampling needle through the first sampling port. Furthermore, a collar (16) is arranged on the external surface of the sample holder vessel in the region of the first sampling port. The collar defines a locating gap (17) in cooperation with the closing element (13) connected with the first sampling port, wherein said locating gap is engaged with a retaining element associated with the sample feeder apparatus so as to ensure immobility of the sample holder vessel relative to the sample feeder apparatus via a stationary fit between said sample holder vessel and said retaining element when sampling operations are performed through at least one of said sampling ports (12, 14).
Abstract:
The invention relates, on the one hand, to a method for producing a medical metallic implant with the properties of antimicrobiality and biocompatibility and, on the other hand, to the metallic implant itself. According to the method, an antimicrobial coating is applied onto a metallic substrate of said metallic implant, the method comprising the steps of arranging said substrate as cathode against a counter electrode in an electrolytic solution containing at least a salt of the metal to be deposited to form the coating, and depositing the coating from the electrolytic solution onto the substrate surface by electrolysis. The essence of the present method is that after an initial pre-treatment of the substrate surface, the electrolysis is performed directly onto the substrate, and said coating is formed as a non-continuous nanostructured coating by pulse current series electrochemical deposition during the electrolysis. The medical metallic implant according to the invention comprises a metallic substrate and an antimicrobial coating, wherein the antimicrobial coating is bound in the form of a plurality of nanostructured microclusters directly to a substrate surface subjected to pre-treatment, and said microclusters are located on said substrate so as to form local galvanic cells when get into contact with an electrolyte.
