Description

Quick quantitative partial shipment liquid medium device

Technical Field

The utility model relates to a quick quantitative partial shipment liquid medium device.

Background

When the dissolved agar liquid culture medium is subpackaged in the tissue culture experiment process, the traditional method is to subpackage the agar liquid culture medium by a measuring cup, a measuring cylinder and the like, but the subpackage efficiency is low, the time is long, and the subpackage is not uniform. The bottle mouth liquid separator can be used for quantitative operation, but belongs to precision equipment, and is easy to cause blockage and damage equipment. Due to the small measuring range of the pipette, the split charging efficiency still needs to be improved. From this, need design the filling ware of a liquid medium that can partial shipment agar, can enough accurately, absorb liquid medium effectively, can carry out the partial shipment again fast, reduce liquid medium's waste, reduce the experiment cost, improve work efficiency.

Furthermore, a pump cover is fixedly arranged on the upper surface of the barrel cover and penetrates through the pump rod.

Furthermore, the quantitative adjusting ring comprises an adjusting ring which is disconnected by a ring and is crossed at the end part but not closed, one end of the adjusting ring is tightly attached to the surface of the pump rod and is a crossed inner ring, the other end of the adjusting ring is tightly attached to the outside of the crossed inner ring and is a crossed outer ring, a plurality of threaded holes are formed in the surface of the crossed outer ring from the outside to the inside, the adjacent threaded holes are partially overlapped, and a knob with an external thread radially penetrates through the crossed outer ring and the crossed inner ring from the outside to the inside in sequence and is screwed and fastened to the surface of the pump rod.

Furthermore, the bottom in the charging bucket is arranged to be a concave arc shape.

Furthermore, the liquid outlet end of the pump head is connected with a rubber tube.

Compared with the prior art, the utility model discloses following beneficial effect has: grip 2-4 test tubes through one hand, stretch into the test tube with the rubber tube, the pump head is pushed down to another hand, when pressing to corresponding scale mark, the adjustable ring will withstand the pump cover and prevent to continue to push down, guarantees fixed output volume to every test tube in, accurate, quick effectual partial shipment culture medium reduces the waste of liquid medium, reduces the experiment cost, improves work efficiency.

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Detailed Description

In order to make the aforementioned and other features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

As shown in fig. 1-5, a quick quantitative partial shipment liquid medium device, including containing bucket 1, containing bucket top is through 2 shutoff of bung, and the bung center is through the vertical containing bucket that penetrates of pump lever 3, pump lever upper end is connected with pump head 4, and pump head lower extreme and pipette 5 intercommunication, pipette coaxial extension in the pump lever go into containing bucket bottom, the pump lever surface is extended its length direction and is provided with scale 6, and the pump lever overcoat between pump head and the bung is equipped with quantitative adjustable ring 7, and zero scale mark generally lies in the scale bottommost, and the scale increases in proper order from bottom to top, with the adjustable ring under the face to the scale mark of accurate needs volume during the use to guarantee to export quantitative culture medium at every turn, avoid extravagant.

In the embodiment of the utility model, the bung upper surface has set firmly pump cover 8, and the pump cover also passes through the pump pole.

In the embodiment of the utility model provides an in, the ration adjustable ring includes by a ring disconnection and in tip alternately but not confined adjustable ring 9, and adjustable ring one end is hugged closely on the pump pole surface, and for alternately inner ring 10, the other end is hugged closely outside alternately inner ring, for alternately outer loop 11, alternately outer loop surface has seted up a plurality of screw holes 12 from outside inwards, and this adjacent screw hole is equal partly overlapped to through a knob 13 of taking the external screw thread radially pass alternately outer loop, alternately inner ring inwards in proper order from outside, connect the fastening soon to the pump pole surface.
