Description
Technical field
The utility model belongs to chemical experimental instrument field, relates to a kind of buret, specifically a kind of detachable buret.
Background technology
Buret is one of volumetric apparatus the most frequently used in chemical experiment, can be used to accurately release Uncertainty liquid, have microburette (below 10ml) and large weighing buret (more than 10ml), wherein the buret application of 25ml and 50ml specification at most.At present, the body of buret adopts integral structure substantially, and for large weighing buret, the body of the buret of 25ml and 50ml specification is longer, has exceeded the size of container cabinet, and it is very inconvenient to wash and deposit, fracture and disrepair phenomenon happen occasionally.
Utility model content
The purpose of this utility model provides a kind of detachable buret, segmentation structure is adopted effectively to be split by the body of buret, solve existing buret Problems existing in washing and depositing, can experimentally need to assemble, can microtitration, can carry out a large amount of titration again, measurement range is wide.
The technical scheme that the utility model adopts:
A kind of detachable buret, comprise water dropper and several sections of body, at the connector of water dropper, internal thread is set, described shaft design is the rod-like structure of hollow and arranges scale mark, one end arranges internal thread, the other end arranges connector, connector external diameter is slightly less than internal diameter of tube body, connector arranges external thread, the internal thread of the external thread of connector and water dropper or body matches, by the internal thread of the connector precession water dropper of first segment body during use, screw connection, the internal thread of the connector precession first segment body of second section body, by that analogy, experimentally need to assemble, can microtitration, a large amount of titration can be carried out again.
Described water dropper is acid water dropper and alkali formula water dropper.
The connector of described body arranges sealing gasket, reaches sealing effectiveness when can ensure connector precession internal thread, avoid liquid reagent to leak outside.
The utility model structure is simple, cost of manufacture is low, segmentation structure is adopted effectively to be split by the body of buret, solve existing buret at washing and Problems existing in depositing, and can experimentally need to assemble, can microtitration, a large amount of titration can be carried out again, measurement range is wide, can repeatedly use, and makes and simple to operate.
Accompanying drawing explanation
Fig. 1 is the structural representation of water dropper of the present utility model.
Fig. 2 is the structural representation of body of the present utility model.
Fig. 3 is installment state design sketch of the present utility model.
In figure: 1, water dropper; 2, internal thread; 3, body; 4, scale mark; 5, connector; 6, external thread.
Embodiment
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 structure shown in Fig. 1,2, the utility model comprises water dropper 1 and several sections of body 3, and water dropper 1 is divided into acid water dropper and alkali formula water dropper, arranges internal thread 2 at the connector of water dropper; Body 3 is designed to the rod-like structure of hollow, employing glass material is made, and scale mark 4 is set, the capacity of every pipe joint body take 10ml as benchmark, one end of body 3 arranges internal thread 2, and the other end arranges connector 5, and connector external diameter is slightly less than internal diameter of tube body, connector arranges external thread 6 and installs rubber ring pad, the internal thread of the external thread of connector and water dropper or body matches.
During concrete operations, as shown in Figure 3, by after body 3 washes clean of water dropper 1 and each 10ml, the internal thread 2 of the connector precession water dropper of first segment body 3, screwing hermetic connects, the internal thread of the connector precession first segment body of second section body, by that analogy, buret is become.Add vs and after adjusting liquid level, start titration; When dropping to 10ml scale, suspending, releasing vs, until the scale place of next pipe joint body, continue titration, so continuously, until titration completes, the scale value of cumulative each joint graduated tube, is total titration number.The length (the use joint number of body) of buret can experimentally need to assemble, can microtitration, can carry out a large amount of titration again.
The above is only preferred implementation 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.
Claims (2)
1. a detachable buret, it is characterized in that: comprise water dropper and several sections of body, at the connector of water dropper, internal thread is set, described shaft design is the rod-like structure of hollow and arranges scale mark, one end arranges internal thread, and the other end arranges connector, and connector external diameter is slightly less than internal diameter of tube body, connector arranges external thread, and the internal thread of the external thread of connector and water dropper or body matches; The connector of described body arranges sealing gasket.
2. detachable buret according to claim 1, is characterized in that: described water dropper is acid water dropper and alkali formula water dropper.
