Embodiment
In order to better understand the utility model, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, a kind of anerobe High pressure culture pipe, comprising:
Culture tube body 1, its both ends open is also provided with outside screw 11 at opening part, and its inwall is provided with one deck corrosion-resistant diaphragm 12, as Fig. 2,3; Preferably, corrosion-resistant diaphragm 12 can adopt jet printing type, also can adopt detachable, so that it is changed after damaging;
Access cover 2 and outlet cap 3, be arranged at the two ends of described culture tube body 1 respectively, sealed by culture tube body 1.
As Fig. 4, described access cover 2 comprises:
Lid 21, be provided with the internal thread 211 mated with described outside screw 11, and the center is provided with through hole 212, as Fig. 5; Make lid 21 knob on culture tube body 1 by internal thread 211 and outside screw 11.
Inlet pipe 22, its one end is communicated with described through hole 212, preferably, is sealed between through hole 212 and inlet pipe 22 by packed-piston 26.
Tensimeter 23, is arranged at the other end of described inlet pipe 22, and the two interface seals, and tensimeter 23 is for measuring the air pressure level in culture tube body 1.
T-valve 24, be arranged between described inlet pipe 22 and tensimeter 23, two interface is communicated with described inlet pipe 22, and the two interface seals.
Two-way valve 25, one end interface is by three orifice of inlet pipe 22 with described T-valve 24, and the two interface seals.
Described outlet cap 3 comprises:
Second lid 31, be provided with the second internal thread 311 mated with described outside screw 11, and the center is provided with the second through hole 312, as Fig. 6; Make the second lid 31 knob on culture tube body 1 by the second internal thread 311 and outside screw 11.
