DUAL DEVICE FOR HANDING BIOLOGICAL MATERIAL IN LABORATORIES
P202330181
A device for handling particles, cells and/or liquids that combines magnetic attraction and aspiration functions in a single device. This technology provides a controlled magnetic field capable of attracting structures (including cells) that have characteristics that allow them to be attracted by magnetic fields and at the same time allows, in a simple and easy way, to decouple the magnetic field so that the cells previously adhered to it can be detached. At the same time, the magnet can be replaced, in a simple, easy and fast way, by a capillary that can also be coupled to the device and that allows, through suction, the manipulation of cells, particles and/or fluids. The device has a design similar to a traditional pipette, consisting of a main tubular element, which has in its upper part with a piece that when pressed allows a rod with the magnet attached to it to move inside and protrude from the back of the tubular element. Thanks to these characteristics, a multifunctional device is achieved that can be adapted to the working needs of each laboratory, allowing the practical, safe and simple handling of different types of biological material, by means of the use of a magnetic field system or by activating the suction system that is integrated in a dual way in the device.
- Versatility. It combines in the same device the double functionality of magnetic attraction and suction, both can be interchanged quickly and easily. - Safety. Reduces the risk associated with human handling of biological material, minimizing the losses associated with this factor. - Ease of handling. It favors the directionality and displacement of the cells on different types of surfaces, adapting to the requirements of each test. - Time saving. Reduces and maximizes the time required for cell mobilization tasks. The device finds its main field of application in any laboratory in the biotechnological or biomedical field. More specifically the device can be used in: - The manipulation of magnetic particles, including magnetic microparticles and nanoparticles. - The manipulation of any type of cells or groups of cells of animal or plant origin attached to any type of magnetic particle or material that confers the ability to be attracted to a magnetic field. - Vitrification processes of cells, oocytes and embryos attached to nano- and/or micro-magnetic or superparamagnetic particles. - In the storage and conservation of magnetic particles.
