A method for transferring a quantity of analytes comprising at least stages of: predisposing a substantially homogeneous mixture of a predetermined initial quantity of at least an analyte and a liquid, obtaining a known concentration value or known amount of the analyte in the mixture; introducing into the mixture at least a collecting portion (3) of a sampling device (1) having a support body (2), the collecting portion (3) comprising a plurality of fibers (6) attached to and arranged on a first portion (2a) of the support body (2) by means of flocking, in order to define a flocked collecting portion (3) or a flocked tampon, such as to collect a part of the mixture on the collecting portion (3); and extracting the collecting portion (3) of the sampling device (1) of the mixture, retaining on the sampling portion (3) a predetermined known quantity of the mixture to be transferred.
A pre-dosed sampling device (1) comprising a support body (2) and a flocked collecting portion (3), the flocked collecting portion (3) including a plurality of fibers (6) attached to and arranged on a first portion (2a) of the support body (2) by flocking, wherein the flocked collecting portion (3) is provided with a dried predetermined and pre-dosed known quantity of an analyte to be transferred, wherein the flocked collecting portion (3) is configured to absorb a quantity of liquid comprised between 10 microlitres and 500 microlitres, by capillarity effect.
A pre-dosed sampling device (1) comprising a support body (2) and a flocked collecting portion (3), the flocked collecting portion (3) including a plurality of fibers (6) attached to and arranged on a first portion (2a) of the support body (2) by flocking, wherein the flocked collecting portion (3) is provided with a dried predetermined and pre-dosed known quantity of micro-organisms to be transferred.
A pre-dosed sampling device (1) comprising a support body (2) and a flocked collecting portion (3), the flocked collecting portion (3) including a plurality of fibers (6) attached to and arranged on a first portion (2a) of the support body (2) by flocking, wherein the flocked collecting portion (3) is provided with a dried predetermined and pre-dosed known quantity of an analyte to be transferred, further comprising a container (7) for transport at least of the collecting portion (3) with the analyte and wherein the container (7) further comprises a predetermined quantity of a substance (8) to liquefy the analyte.
A pre-dosed sampling device (1) comprising a support body (2) and a flocked collecting portion (3), the flocked collecting portion (3) including a plurality of fibers (6) attached to and arranged on a first portion (2a) of the support body (2) by flocking, wherein the flocked collecting portion (3) is provided with a dried predetermined and pre-dosed known quantity of an analyte to be transferred, wherein said analyte is chosen from the group consisting of:
