Abstract
Description
- The present invention relates to a tempering clamp for a sample container used for holding the container and heating or cooling the sample contained within the container.
- Generally, sample holders known in the art are rigid and inflexible and therefore, hardly suitable for providing tolerance compensation of different sample holders or sample tubes.
- It is known in the art to use sample holders together with tempering elements in the domain of chemistry and medical science in order to temper, i.e. to heat or to cool, the sample contained within the sample holder.
- Using conical or conical/cylindrical formed sample tubes a close contact can be achieved by pressing against the conical part of the heating element by pressure from above. For this, an additional corresponding device is necessary allowing for axial force transmission, for example, by a pressing lid. During tempering, the sample tube is not accessible at all even not from above. Therefore, no sample tubes can be used which form part of a microfluidic environment as a microfluidic chip.
- In contrast thereto, the invention proposes a tempering clamp according to claim 1, for holding a sample container and for tempering a sample contained within the sample container. The tempering clamp comprises first and second clamping jaws movably, especially manually movably, connected by a spring element, and first and second tempering elements. The first tempering element is associated, e.g. connected or attached, to the first clamping jaw and the second tempering element is associated, e.g. connected or attchached, to the second clamping jaw.
- In one embodiment, a first heat insulator is attached to the first tempering element and a second heat insulator is attached to the second tempering element.
- Furthermore, the first and second heat insulators can be cooling elements.
- In another embodiment, the first and second tempering elements are adapted for heating and/or cooling the sample. Peltier elements can used as tempering elements.
- In one embodiment, an element is provided for effecting contact pressure in axial direction.
- Furthermore, the spring element comprises a spring steel sheet.
- For monitoring and controlling the tempering process a temperature sensor can be provided. Further sensors, e.g. for pH-value, oxygen partial pressure, etc., can be provided.
- In one embodiment, the spring element is biased. Furthermore, outer surfaces of the tempering clamp can constitute an inwardly directed V-form. This can be achieved, for exmaple, by biasing the spring element.
- Moreover, the tempering clamp can adapted to receive a microfluidic chip.
- A method for holding a sample container and tempering a sample contained within the sample container uses a tempering clamp according to one of claims 1 to 12.
- In one embodiment, the tempering process is monitored by a sensor inserted into the sample container from above.
- The present application proposes a clamp serving as a heating element which is suitable for holding a sample tube serving as a sample container to be tempered and holding the sample holder with a radial pressure. In one embodiment, the clamp comprises two half shells reproducing the three-dimensional structure of the sample tube. However, the cavity between the half shells can be slightly smaller than the volume of the sample tube. The two half shells are connected by a flat spring which will be extended during insertion of the sample tube into the cavity between the half shells automatically building a radial contact pressure onto the outside surface of the sample tube.
- Further features and embodiments of the invention will become apparent from the description and the accompanying drawings.
- It will be understood that the features mentioned above and those described hereinafter can be used not only in the combination specified but also in other combinations or on their own, without departing from the scope of the present invention.

Figure 4 shows thetempering clamp 10 together with asample tube 50 inserted into the temperingclamp 10, especially in between the twoclamping jaws tempering clamp 10. Furthermore, a microfluidic chip is attached to the temperingclamp 10. The temperingclamp 10 serves as a lysis clamp the microfluidic chip is attached to. -
Figure 5 shows a detail offigure 4 encircled and denoted withreference number 52. The drawing shows thesample tube 50 inserted in between the twoclamping jaws sample tube 50 is securely fixed in the cavity between the twoclamping jaws clamping jaws gap 54 between thefront edges clampering jaws - The tempering clamp according to the invention can be used for sample tubes which are rigidly connected to a microfluidic chip and can be heated up to 60 °C. The sample contained in the sample tube can contain biological cells in suspension and a so-called lysis buffer. By influence of the buffer and the increased temperature, the cells will be decomposed, that means lysed.
- After completion of the lysis, the liquid overlap of the sample tube will be transferred into the microfluidic of the chips. Therefore, the lid on the sample tube must be manipulated.
- In this case, the head room filled by air of the tube will be pressurized by pumping air so that liquid can rise through a riser pipe. It is also possible to work with negative pressure. In both cases, it must be accessible by corresponding pipes. On the chip, there are micromechanic valves which can be operated by external actors.
- Furthermore, applications for the tempering clamp are in the field of a thermostating chamber for incubation, biochemical reactions as amplification reactions, kinetic measurements or similar applications needing a rapid heat transportation.
- The application enables a fast heat transfer from a heating block to a sample tube containing a sample, in many cases a liquid sample.
- For this purpose, the tempering clamp provides a close contact of the heating element by radial contact pressure onto the sample tube to compensate for tolerances of the heating element and the sample tube. The contact pressure should be automatically adjusted by insertion of the sample tube into the heating element.
- Manual adjustment of the contact pressure or other measures and arrangements, as, for example, additional components or manipulation by the user, should be avoided.
- To solve this problem, the invention provides in one embodiment a heatable sample tube holder in form of a clamp or bracket consisting of two half shells being connected by a flat spring element. The spring element causes a pressure being effective in radial direction by insertion of the sample tube by means of contact faces of the clamp onto the wall of the sample tube.
- The two half shells form a cavity in between each other correspondig to the form of the sample tube. It is to be noted that the outer circumference or outer volume of the sample tube should be slightly bigger than the inner circumference or inner volume, respectively, of the clamp to cause the spring contact pressure.
- In one embodiment, the sample tube is cylindrical. Accordingly, the two half shells as well form a cylindrical cavity. The outer surfaces of the clamp can be plane in order to attach the heating elements an the body of the flat spring. Thereby, in one embodiment, the result is a clamp having a rectangular or quadratic layout, projected alongside the cylindrical axis.
- In another embodiment, the outer surfaces of the clamp the flat spring is attached to constitute a flat inwardly directed V-form. Thus, the flat spring is biased and having the same spring constant the contact caused by insertion of a sample tube is higher in comparison with a clamp having a rectangular layout.
- The cavity in between the two half shells can be conical, conical/cylindrical in shape. The conical part should be in the lower part of the cavity in case the sample tube is inserted top down.
- The clamp according to the inventions provides for an optimal thermal contact between the heating element and the sample container to be tempered by radial pressing the heated contact faces without the need for using additional components or additional manual steps.
- The contact pressure is defined to a certain extent by the spring constant and the difference in dimension between the inner volume of the cavity of the clamp and the outer volume of the sample tube. In case fastening faces being in V-form to each other the pressure is additionally defined by the bias force and the structure of the layout of the tempering clamp for the flat spring.
- Furthermore, the sample tube remains accessible from above during tempering. Therefore, a fluidic functional part, for example a microfluidic chip, can be connected to the sample tube by means of a suitable adapter as a thread, bayonet, plug or clip connection. In this manner fluidic processes can be performed with the fluid contained within the sample tube.
- Alternatively, the processes within the tempered sample tube can be monitored by means of an optical aperture or corresponding optical detection and supervising devices. The tempering procedure can be supervised by detectors or sensors inserted from above (temperature, pH-value, oxygen partial pressure, etc.). Furthermore, the sample tube can be charged or discharged from above. Moreover, the pressure in the region above the liquid can be increased or decreased.
