Description
Technical Field
The utility model relates to a buret field especially relates to a bioengineering is with portable buret.
Background
A burette refers to a meter that holds a titrant solution during a titration operation. The burette is a slender glass tube with scales and uniform inner diameter, and the lower end of the burette is provided with a glass sharp mouth with different volumes of 25ml, 50ml and the like. The main part of the burette is made of a glass tube with uniform inner diameter and accurate scale, the lower end of the burette is connected with a glass cock or a latex tube containing glass beads for controlling the liquid outflow speed, and the bottom end of the burette is connected with a sharp-nose glass tube. The burette with the lower end provided with the glass cock is called an acid burette, is usually used for measuring the volume of a dripped non-strong alkaline dilute solution, is not suitable for containing an alkaline solution, and can corrode glass due to long-time storage of the alkaline solution, so that the cock can not rotate.
Current bioengineering is with portable buret leans on personnel handheld buret to be vertical state usually, then carries out the reading, and the manual work is vertical can't ensure the buret with the buret and is vertical state, when carrying out the reading again, has the error, and to the researcher of not good eyesight have very big inconvenience when the reading, lead to when calculating, the precision is not high, for this reason, we propose a bioengineering is with portable buret, solve above-mentioned problem.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing a portable burette for bioengineering.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a bioengineering is with portable buret, includes bottom plate, second round bar, first round bar and rubber snap ring, first round bar and second round bar are all fixed at the bottom plate upper surface, first round bar is located second round bar front side, second round bar right-hand member is fixed with two second connecting rods, two the second connecting rod sets up from top to bottom, the rubber snap ring is provided with two and fixes respectively at two second connecting rod right-hand members, two the buret body is fixed jointly to the rubber snap ring, buret body lower extreme is provided with the glass piston, be provided with the sleeve on the first round bar, sleeve annular side right-hand member is fixed with the head rod, the head rod right-hand member is fixed with the magnifying glass.
Preferably, the caliber of the sleeve is matched with that of the first round rod.
Preferably, the right end of the rubber snap ring is provided with an opening, and the caliber of the opening is smaller than that of the burette body.
Preferably, the annular side face in the rubber snap ring is provided with anti-skid grains.
The utility model has the advantages that: the opening through passing the buret body rubber snap ring right-hand member is placed in the rubber snap ring, makes the buret body keep the vertical state to precision when improving the reading through removing the sleeve, drives head rod and magnifying glass through the sleeve and removes, enlargies the scale mark on buret body surface through the magnifying glass, thereby the reading of being convenient for, and then reduced the error.
The utility model discloses be convenient for make buret body keep the vertical state when the reading, guaranteed the handheld error that causes, be convenient for simultaneously observe the height of this internal liquid of buret, precision when having improved the reading.
Drawings
Fig. 1 is a front view of the portable burette for bioengineering of the present invention.
Fig. 2 is a top cross-sectional view of the portable burette for bioengineering according to the present invention.
Reference numbers in the figures: 1 first round bar, 2 second round bars, 3 second connecting rods, 4 rubber snap rings, 5 magnifying glasses, 6 buret bodies, 7 glass pistons, 8 bottom plates, 9 first connecting rods and 10 sleeves.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, a portable burette for bioengineering, comprising a base plate 8, second round bar 2, first round bar 1 and rubber snap ring 4, first round bar 1 and second round bar 2 are all fixed at 8 upper surfaces of bottom plate, first round bar 1 is located 2 front sides of second round bar, 2 right-hand members of second round bar are fixed with two second connecting rods 3, two second connecting rods 3 set up from top to bottom, rubber snap ring 4 is provided with two and fixes respectively at 3 right-hand members of two second connecting rods, burette body 6 is fixed jointly to two rubber snap rings 4, 6 lower extreme of burette body is provided with glass piston 7, be provided with sleeve 10 on the first round bar 1, sleeve 10 annular side right-hand member is fixed with head rod 9, head rod 9 right-hand member is fixed with magnifying glass 5.
The bore of sleeve 9 and first round bar 1 phase-match make sleeve 10 can reciprocate along first round bar 1, and 4 right-hand members of rubber snap ring are provided with the opening, and the opening bore is less than the bore of buret body 6, are convenient for place buret body 6 and prevent that buret body 6 from droing, and the annular side processing has anti-skidding line in the rubber snap ring 4.
The working principle is as follows: the device is when using, use and accomplish the back of titrating at buret body 6, get into in rubber snap ring 4 with the opening that buret body 6 passed 4 right-hand members of rubber snap ring, thereby it is fixed with the upper and lower both ends of buret body 6 through rubber snap ring 4, and then make buret body 6 keep perpendicular device, the error of reading when having avoided handheld buret body 6, then user removes sleeve 10, sleeve 10 removes along first round bar 1, drive head rod 9 and magnifying glass 5 simultaneously and remove, through liquid level in magnifying glass 5 and the buret body 6, enlarge the scale mark on buret body 6 surface under the effect of magnifying glass 5, thereby convenient to use person observes, and then the precision of reading has been improved.
