Definitions
- the invention relates to a receptacle for sample containers, in particular elongate sample containers such as cuvettes or test tubes. Such recordings can be used in particular when cleaning sample containers.
- Sample containers such as cuvettes or test tubes are usually made of quartz glass or glass and relatively expensive. They are reused and must be cleaned cleanly and without residue before reuse.
- sample containers are held individually in the hand, with gloves to be worn and a high risk that a sample container will break during manual cleaning. If sufficient
- cleaning devices are capable of accommodating a maximum of two cuvettes and require a vacuum pump. When cleaning residues of non-hazardous sample solutions, such as. B. incurred in food and biochemistry, these cleaning devices do not provide satisfactory
- Sampling containers are easy to pick up in the receptacle, stay safely and reliably absorbed and light
- the receptacle should preferably be designed such that recorded sample containers can be cleaned reliably and cleanly.
- several sample containers should also be able to be taken in order to carry out the cleaning at the same time.
- Cleaning device for receiving at least one preferably elongate sample container, in particular cuvette, the one opening and one of the opening in a longitudinal direction opposite, the sample container occlusive bottom, provided for cleaning such a sample container, wherein the receptacle is a first element for
- the first element has a passage which is formed such that it at least partially overlaps with the opening of the sample container when receiving the sample container, and is formed, when receiving the sample container, fluid for cleaning the sample container through the opening and
- first and second elements being arranged such that the sample container is held between the first and second elements
- Sample container abut.
- the first member abuts the opening of the sample container such that the edge of the opening is in contact with the first member from the longitudinal direction.
- the bottom bears against the second element.
- Sample container is thus between the first and second
- Element in the longitudinal direction in particular positively held, and is preferably clamped between the first and second elements in the longitudinal direction.
- the first element In the region of the opening of the sample container, the first element has such a configuration that introduced into the sample container when applied to the first element fluid for cleaning, such as cleaning fluid and compressed air, through the opening and the passage and again can be executed.
- the passage in the first element allows the opening of the sample container during the recording of the
- Sample container Cleaning fluid can be injected into the sample container, bounce against the bottom of the sample container and re-emerge through the opening and the passageway. Cleaning fluid can thus both on the opening of the sample container and the passage in the first element both enter and exit, in particular at the same time.
- the cleaning can be done sufficiently accurate and residue-free, while the sample container is securely and firmly received in the recording.
- increased pressure cleaning fluid or compressed air for example, with increased pressure cleaning fluid or compressed air
- Sample container or the multiple sample containers is problematic.
- a secure containment of sample containers can be achieved, and when using the recording during cleaning, a thorough and reliable cleaning for a
- the present invention is suitable for a variety of cuvettes or test tubes or in general for
- sample containers with an opening and an opposite bottom.
- the present invention is particularly useful with cuvettes
- Plug closure or screw cap suitable.
- the longitudinal direction of the cuvettes can in particular be square.
- Cleaning device may comprise the recording according to the invention.
- it may have a unit for dispensing cleaning fluid and / or a unit for pressurizing with compressed air.
- the first element on the passage at least partially on a recess in the longitudinal direction, wherein the recess has a greater width than a width of the passage in a direction perpendicular to the longitudinal direction.
- the width of the depression is dimensioned so that a portion of the sample container in
- the recess and the passage are formed as a step, wherein the sample container in a lateral direction perpendicular to the longitudinal direction at the
- the first element is substantially formed as a plate and has a recess or bore which forms the passage.
- the recess can be realized for example in the form of a circular or oval cutout.
- the first element may comprise at least two substantially parallel to one another and in a direction perpendicular to the longitudinal direction
- the distance of the rails from each other is in particular smaller than an outer diameter of the sample container along the direction of the distance of the rails, so that the sample container can lie in the longitudinal direction of the rails.
- the recording according to the invention is suitable for simultaneous
- the spring device is designed such that when biasing the spring device in the longitudinal direction of the distance between the first and second element for inserting the sample container is increased.
- Spring device is on the one hand, the insertion or
- the sample container can be held in the recording more reliable by the at least slightly biased spring clamps the sample container between the first and second element or clamped.
- the spring device may comprise a spring element which is arranged such that it absorbs when receiving the
- Spring element may be arranged such that when receiving the sample container on the side of the first or second element oriented away from the sample container
- the spring device can in
- Spring element for example a spiral spring, may be arranged around the punch.
- Sample container can rest on the stamp.
- the receptacle can accommodate a plurality of sample containers.
- the sample containers may be arranged in a row in a direction perpendicular to the longitudinal direction. Also multi-row arrangements are conceivable.
- a multi-row arrangement has the additional advantage that the receptacle has an improved stability compared to a relatively narrowly constructed receptacle with a single-row receptacle of the sample containers.
- the stability can be improved by boom.
- the receptacle has feet, which is a setting up the recording without touching the
- Support surface on which the receptacle is arranged so in particular the laboratory table allow.
- the receptacle can be pivotable so that the recorded sample container can be tilted in the receptacle. This is advantageous because by tilting or tilting the recording residual cleaning liquid can run out of the sample container.
- Final cleaning step for removing the water commonly used cleaning fluids include in particular ethanol and isopropanol, as they can be blown off evenly and without residue by compressed air.
- the first and second elements are therefore preferably made of polyethylene or polypropylene
- fluoropolymer plastics such as polytetrafluoroethylene or its copolymers.
- stamp is particularly advantageous the use of silicone rubber or fluoroelastomer.
