Abstract
The utility model discloses a multifunctional burette. The multifunctional burette comprises a burette body (10), wherein a rubber nipple (1) capable of absorbing liquid is arranged at the top end of the burette body (10); a liquid inlet pipe (9) erecting upward is connected to the middle upper position of the burette body (10); the lower end of the burette body (10) is connected with a water outlet (5) with a rough external surface; a valve K2 (12) is arranged above the water outlet (5); two branch pipes are arranged between the lower part of the burette body (10) and the upper part of the valve K2 (12); the two branch pipes are respectively connected with a detachable acidic burette head (3), which is bent downward, and a basic burette head (4) by screw threads; a valve K1 (11) is arranged on the branch pipe connected with the acidic burette head (3); a valve K3 (13) is arranged on the branch pipe connected with the basic burette head (4); and scale lines are arranged on the burette body (10). The multifunctional burette disclosed by the utility model has the advantages of multiple functions, simplicity in making, simplicity and convenience in operation, economy of resource and time, and the like.
Description
Technical field
The utility model relates to a kind of buret, is specially collection suction pipe, acid buret, base buret and pipette functions and is Mobyneb buret all over the body.
Background technology
The accurate type of present requirement of experiment is high, and therefore, the liquid of testing in the used instrument is pure, so cleaning experiment apparatus that will be frequent when experiment.The used instrument great majority in laboratory are not the designs of kinds of experiments instrument disjunctor; The per capita resources occupancy volume of China is made the matter worse; The design of this pipe can save time and resource, has accomplished kinds of experiments instrument disjunctor, the design of one tube multipurpose.
The utility model content
The purpose of the utility model is to provide a kind of multi-functional buret that can address the above problem, and the purpose of the utility model is to be achieved through following technical scheme:
A kind of Mobyneb buret, comprise body it is characterized in that the top of said body be provided with one can imbitition the rubber nipple, said body middle part connects a feed tube straight up in the position on the upper side; Said body lower end connects the coarse delivery port of outer surface, and the top of delivery port is provided with valve K
2, the bottom of body and valve K
2Part between the top is provided with two arms respectively through the crooked downward acid buret head and the base buret head of threaded connection detachable, and the arm that connects the acid buret head is provided with valve K
1, the arm that connects the base buret head is provided with valve K
3, also be provided with graduation mark on the said body.
The beneficial effect of the utility model is:
1. multitube disjunctor saves material and makes the expense that similar pipe is;
2. can arbitrarily dismantle, accomplish one tube multipurpose, save parking space;
3. easy and simple to handle, save time: discharging during waste liquid the experimenter only need to connect a long rubber tube and be connected with delivery port and can accomplish in the original place.
