Pipette, buret, conical flask and iron stand etc.；In experimentation, conical flask is usually placed on to the base of iron stand
On, then corresponding buret is fixed on the support bar of iron stand by sliding block and operated, and the instrument such as pipette needs
Placed using other rack for test tube.
In actual mechanical process, experiment each time is required for that test apparatus is carried out to collect and arrange again；When multiple
, it is necessary to constantly be changed to the instrument on iron stand during experiment continuous operation, mostly separately put, led due to laboratory apparatus
Cause takes, puts instrument and is required for expending more time, so not only causes experiment progress to delay, while take, put process in instrument
In, easily cause instrument to be damaged.
Utility model content
The utility model is intended to provide a kind of titration experiments rack, is being carried out with solving iron stand of the prior art
, it is necessary to the problem of constantly taking, putting instrument during continuous experiment.
A kind of titration experiments rack in this programme, including geometrical clamp, base and the support bar being arranged on base,
Placing frame is connected with support bar, placing frame includes at least two horizontal positioned crossbeams, longeron is connected between adjacent beams；Gu
Clamp includes sliding block, and sliding block is slidably connected with crossbeam, longeron；Sliding block is provided with the liquid relief for being used for fixing pipette and pressed from both sides and for solid
Determine the test tube clamp of buret；The base is provided with the holding tray that can at least place 3 conical flasks.
The working principle and beneficial effect of this programme：During titration experiments, it would be desirable to which the conical flask used is placed on holding tray
It is interior, then multiple geometrical clamps are placed on placing frame, buret and pipette are consolidated using the test tube clamp on geometrical clamp and liquid relief folder
It is fixed；Then buret or pipette is controlled to move by mobile sliding block, being added dropwise by buret or pipette into conical flask needs
The dosage wanted, so as to complete titration experiments；It is used to fix pipette and the liquid relief folder of buret and examination because geometrical clamp is provided with
Pipe clamp, single geometrical clamp are that the control to buret and pipette can be achieved, and are advantageous to improve conventional efficient.In experimentation,
Generally require and carry out the parallel laboratory test of more than 3 times, then take the average value of result to improve the accuracy of experimental result；And place
3 conical flasks can be at least placed in disk, can realize that institute is added dropwise to 3 conical flasks in pipette and buret by mobile sliding block
The addition of dosages of substance is needed, avoids prior art after completing that a conical flask is added dropwise, it is necessary to which the conical flask is taken
Walk, then other conical flask is taken into the problem of being added dropwise, so as to improve test efficiency.
When entering Line Continuity titration experiments, because sliding block and crossbeam, longeron are slidably connected, by mobile sliding block make its
Slided on crossbeam and longeron and be moved to used pipette and buret on one side, then slided other geometrical clamp by sliding block
Move to the top for the holding tray that will be tested, material, which is added dropwise, to the conical flask of lower section using pipette or buret completes experiment.
By the setting of crossbeam, longeron and geometrical clamp, and it is used in conjunction with each other；Once experiment needs are avoided to take away and take
The problem of carrying out a collection of laboratory apparatus, the efficiency of experiment is improved, simultaneously because the reduction that instrument is moved, reduces what instrument was damaged
Probability.
Further, the junction of the crossbeam and longeron is provided with the breach for placing the sliding block, and the lower surface of sliding block is provided with
The chute of " ten " font, chute are slidably connected with the crossbeam, longeron.The junction of crossbeam and longeron, which is provided with, places the sliding block
Breach and sliding block lower surface be " ten " font chute, when needing to make sliding block switch between crossbeam and longeron, will
Sliding block slides into gap position, and " ten " the font chute set using sliding block lower surface can quickly realize sliding block in crossbeam with indulging
Switching between beam.
Further, the upper surface of the base is provided with the recessed fourth of the twelve Earthly Branches, and the bottom of the holding tray is provided with what is be slidably connected with the recessed fourth of the twelve Earthly Branches
Tenon.By setting the recessed fourth of the twelve Earthly Branches on base, tenon is set in the bottom of holding tray, holding tray is achieved the cunning on base
Dynamic, by sliding holding tray, the buret and pipette that can make the conical flask in holding tray and top are preferably coordinated, and are had
Beneficial to the progress of titration experiments；Meanwhile being slidably connected between holding tray and base makes holding tray more stable on base, helps
Rocked in avoiding holding tray；In addition, when entering Line Continuity titration experiments, it is more by sliding holding tray control when changing experiment
The position of individual holding tray, be advantageous to the progress of next experiment.
