Abstract: The mould includes a tubular wall (1), a base (2) and a pair of flanges (3), one at the open end of the tubular wall and the other around the base, which are formed of a single piece. The method consists in injecting plastic material (14), preferably copolymers, polypropylenes or polyethylenes, between a mould and a core (11), drawing the formed piece from the mould at a piece temperature of between 100 and 150 DEG C, without forced cooling of either mould (8) or core (11), the latter being kept at a temperature between 90 and 120 DEG C, with the moulding time being between 3 and 7 minutes. This allows the mould to be manufactured more quickly and simply. <MATH>

Abstract: El desarrollo de la Electroforesis Capilar como técnica analítica, ha supuesto la posibilidad de su utilización en un gran número de nuevas aplicaciones. Algunas de estas aplicaciones, sobre todo en el campo de la biotecnología, suponen el uso de columnas capilares que garanticen el control del flujo electroosmótico, especialmente por dar lugar a flujo electroosmótico prácticamente nulo y flujo electroosmótico invertido, eliminando al mismo tiempo los efectos de adsorción entre las sustancias a analizar y la pared interna del capilar. En esta patente se propone un método para la obtención de columnas capilares recubiertas con polímeros que aseguran estos dos supuestos, tratándose de polímeros neutros hidrófilos en el primero y polímeros con carga positiva en el segundo. El método asegura la reproducibilidad de los resultados analíticos derivados de su uso.
