1. An apparatus for introducing a fluid into a tube having a self-sealing closure means, said apparatus comprising:

  • a base;

    clamping means having a substantially hemi-tubular construction for releasably clamping the tube against the base at a fluid injecting station and for releasably maintaining the tube in a substantially horizontal position;

    injector means including a first hollow injector needle selectively engageable with said closure means;

    means for enabling the needle to penetrate the closure means thereby introducing a charge of liquid into the tube and for enabling the needle to be withdrawn from the tube; and

    means for raising and lowering the clamping means relative to the tube so that in a first position of use, the clamping means is in engagement with the tube so as to bias the tube gently but firmly downwards against the base and in a second position of use the clamping means is out of engagement with the tube.
