  • a specimen transfer device adapted to receive a sample, comprising;

    a housing having a first end, a second end, a sidewall extending therebetween, a dispensing tip at the first end, an actuation member at the second end, and a valve disposed within the dispensing tip, the actuation member movable between a first position and a second position, the valve transitionable between a closed position and an open position;

    a deformable material having pores and disposed within the housing, the material deformable from an initial position in which the material is adapted to contain the sample to a deformed position in which at least a portion of the sample is released from the material; and

    aviscoelastic member disposed within the housing between the material and the sidewall of the housing and between the material and the actuation member,wherein the viscoelastic member is engaged with the actuation member and the material such that movement of the actuation member from the first position to the second position exerts a force on the viscoelastic member which deforms the material from the initial position to the deformed position, andwherein with the material in the deformed position and the valve in the open position, the portion of the sample released from the material may flow through the dispensing tip; and

    a sample testing device having a receiving port adapted to receive the dispensing tip of the specimen transfer device for closed transfer of at least a portion of the sample from the specimen transfer device to the sample testing device.
