Apparatus for filling tubes.

摘要

An apparatus (10) comprises a conveyor system 11 for conveying tubes (12), having respective self-sealing closure means, sequentially to a station whereupon the conveyor system (11) is temporarily halted. At the station, a clamping means (13) having a clamp (13a) lowers to prevent movement of the tube (12a). An arm (19) moves in the direction of the tube (12a) to enable a hollow needle (17) to penetrate the closure means (30) of the tube (12a). A metering means (15) enables a predetermined volume of a fluid, preferably liquid agar, to be introduced into the tube (12a). Following release of the needle (17) from the closure means (30), the conveyor systems moves to enable another tube (12b) to arrive at the station.
