Description
Technical field
The utility model belongs to chemical experimental instrument field, relates to a kind of centrifuge tube, specifically a kind of twoport centrifuge tube.
Background technology
In soil physical analysis, often adopt centrifugal extraction method to carry out the analysis of soil mineral available state, namely have in the centrifuge tube of sample at title and add a certain amount of extract, centrifugal on ultrasonic wave or the rearmounted centrifuge of oscillation treatment, isolate testing sample solution.After centrifugal treating, active ingredient to be measured in pedotheque is dissolved in the middle of extract, and then under the influence of centrifugal force, precipitation condenses in bottom centrifuge tube remaining sample particle residue, gets transfer supernatant liquor, namely becomes testing sample solution.After sample solution processes, need to clear up the sample particle residue bottom centrifuge tube, so that the use of next time, now, due to the effect of centrifugal force, the soil particle residue be deposited in bottom centrifuge tube hardens into lump, be difficult to wash-out, usual employing is firmly beaten bottom centrifuge tube repeatedly, with shatter lump, so causes that centrifuge tube easily breaks, noise, the problem such as time-consuming.
Utility model content
The purpose of this utility model provides a kind of twoport centrifuge tube, scum pipe is offered by the lower bottom part at centrifuge tube, can realize extracting rear sample particle residue fast and easy wash-out, solve the problem that existing centrifuge tube is difficult to eluting particles residue, effectively increase work efficiency.
The technical scheme that the utility model adopts:
A kind of twoport centrifuge tube, comprises centrifuge tube body, it is characterized in that bottom opening at centrifuge tube body and arranges the column scum pipe of hollow, for collecting precipitation granular residue, the outer wall of scum pipe arranging screw thread; Separately be provided with end opening screw lid, for shutoff scum pipe, end opening screw lid is made up of enclosing cover, the hollow columnar riffled tube be arranged in cover bottom portion, screw thread on the internal thread of riffled tube and the outer wall of scum pipe matches, caliber is slightly larger than scum pipe, by the riffled tube precession scum pipe of end opening screw lid, make its shutoff scum pipe, now the lid of enclosing cover is tight-lipped againsts centrifuge tube body, secondary seal can be carried out, the integraty of centrifuge tube body and end opening screw lid can be embodied again, facilitate experimental implementation.During operation, under the influence of centrifugal force, soil particle residue is deposited in the middle of centrifuge tube lower end and scum pipe; After processing sample liquid, rotate and take off end opening screw lid, with tap water or backwash centrifuge tube, due to the permeability at twoport centrifuge tube two ends, pedotheque residue lump can be gone out by hydraulic pressure smoothly, washs very convenient, substantially increases operating efficiency.
The mouth of pipe wall arranged outside external screw thread of described centrifuge tube body, facilitates the mouth of pipe (injection port) screwing hermetic with helixseal lid.
The enclosing cover mouth of described end opening screw lid arranges sealing ring, effectively can realize secondary seal, avoids extract in centrifugal process flow out or ooze out.
The utility model structure is simple, easy to use, scum pipe is offered by the lower bottom part at centrifuge tube, the pedotheque residue hardened bottom centrifuge tube can be got out express developed, solve the problem that existing centrifuge tube is difficult to eluting particles residue, effectively increase work efficiency, make experimentation saving of work and time, repeatedly can use, decrease centrifuge tube consumption, reduce experimental cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of end opening screw lid of the present utility model.
In figure: 1, centrifuge tube body; 2, external screw thread; 3, end opening screw lid; 4, scum pipe; 5, enclosing cover; 6, riffled tube.
Detailed description of the invention
Below in conjunction with accompanying drawing with by embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
In the construction shown in fig. 1, the utility model comprises centrifuge tube body 1, at mouth of pipe wall arranged outside external screw thread 2, centrifuge tube body bottom opening and the column scum pipe 4 of hollow is set, the outer wall of scum pipe arranges screw thread; In the bottom activity of centrifuge tube body, end opening screw lid 3 is set, for shutoff scum pipe 4.
In the structure shown in Fig. 2, end opening screw lid 3 designed by the utility model is made up of enclosing cover 5, the hollow columnar riffled tube 6 be arranged in cover bottom portion, screw thread on the internal thread of riffled tube 6 and the outer wall of scum pipe 4 matches, caliber is slightly larger than scum pipe, utilize screw thread by the riffled tube 6 precession scum pipe 4 of end opening screw lid 3, make its shutoff scum pipe, sealing ring is set at enclosing cover mouth, effectively can realize secondary seal, avoid extract in centrifugal process flow out or ooze out.
During operation, with scum pipe 4 screwing hermetic of end opening screw lid 3 by centrifuge tube body 1 bottom, through sampling with liquid feeding after, with helixseal lid by injection port screwing hermetic, then centrifuge tube is put centrifuge carries out centrifugal, topple over sample liquid process.After processing sample liquid, open the seal cover of injection port and slag-drip opening, with tap water or backwash centrifuge tube, due to the permeability at twoport centrifuge tube two ends, pedotheque residue lump can be gone out by hydraulic pressure smoothly, completes the cleaning of centrifuge tube, so that the use of next time.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
