Abstract

The utility model discloses a measurable rotary evaporating flask. According to the measurable rotary evaporating flask, a longitude line is formed at the inner side or outer side of an evaporating flask body, the lowest point of the longitude line in the vertical direction is taken as a zero-graduation point, graduation points corresponding to readings are upwardly and sequentially marked along the zero-graduation point of the longitude line, and a latitude line is formed on the flask body through the graduation points on the longitude line. When the reading is performed, the volume of liquid can be directly read through observing the longitude line corresponding to the flat surface of the liquid and corresponding to the graduation on the longitude line.

Description

A kind of measurable rotary evaporation bottle

Technical field

The utility model relates to a kind of utensil, definite says a kind of evaporative flask that just can show when rotated reading.

Background technology

No matter the rotary evaporation bottle of selling in the market and using, be ball-type or ellipse, all there is no scale on body, cannot directly read the amount of solvents in bottle.Chinese patent 201110273918 discloses a kind of by the method for monitor strain sheet deformation, finally realized the surplus of measuring solution in evaporative flask, but this measuring method needs the conversion of information, transmit and pass through the amount that the sequence of operations programs such as CPU calling data storehouse transmits control signal can draw solution in evaporative flask.Because operation sequence is too complicated, the various error that will cause of intermediate link is relatively bigger than normal, has not only increased production cost, and has reduced the stability of system, affects the result of use of product.

Summary of the invention

The purpose of this utility model is just to provide a kind of measurable rotary evaporation bottle, and master scale is directly equipped with on rotary evaporation bottle, in the process of production line experiment, just can directly say and read this number, to reduce production costs, improves the application function of product.

Scheme of the present utility model is comprised of evaporative flask and warp and parallel, its design feature is to be equipped with a warp in inner side or the outside of evaporation bottle, using warp minimum point in the vertical direction as zero graduation point, zero degree point along warp upwards marks the calibration points of corresponding reading successively, by the calibration points on warp, on bottle, make parallel again, described parallel can be a semi-circular line of prolonging the bottle full circle line of a week or prolonging bottle half cycle, during reading, observe the corresponding parallel of liquid plane, again by the scale on the corresponding warp of parallel, can directly read the volume of liquid.

The utility model is simple in structure, reasonable in design, and processing is convenient, and result of use is good.

Below in conjunction with accompanying drawing, be described in further detail.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Fig. 2 is that rotary evaporation bottle is used view.
