Abstract

DISPOSITIVO DE TRANSFERENCIA DE LIQUIDO QUE INCLUYE UN SUSTENTADOR PARA UN SISTEMA DE PIPETAS. UNA MEMBRANA PREFORMADA FLEXIBLE (17) QUE POSEE CUBETAS (19) ESTA COLOCADA ENTRE LAS ABERTURAS PROXIMALES DE LAS PIPETAS (23), SOBRE ELLAS, Y UNA CARCASA (11), CON LAS CUBETAS EXTENDIENDOSE HACIA LAS ABERTURAS PROXIMALES DE LAS PIPETAS. UN EXTRACTOR DE VACIO EN LA CARCASA ASPIRA LA MEMBRANA ALEJANDOLA DE LAS ABERTURAS PROXIMALES, CREANDO, DE ESTE MODO, UNA PRESION REDUCIDA EN LAS PIPETAS, LAS CUALES, CUANDO SUS EXTREMOS DISTALES ESTAN SUMERGIDOS EN UN LIQUIDO, EXTRAEN PARTE DEL LIQUIDO HACIA LAS PIPETAS EN CANTIDADES SUSTANCIALMENTE IGUALES. EN UNA DE LAS REALIZACIONES DEL DISPOSITIVO, EXISTE UN TOPE MOVIL (13) PARA CONTROLAR EL RECORRIDO ASCENDENTE DE LA MEMBRANA ABSORBIDA Y, POR TANTO, LA CANTIDAD DE LIQUIDO EXTRAIDO EN LAS PIPETAS. TAMBIEN SE MUESTRA UN METODO PARA FABRICAR LA MEMBRANA PREFORMADA.
