Abstract
The invention relates to a sampling assistant tool of a rheometer. The sampling assistant tool comprises a needle cylinder, a discharge nozzle, a piston, a sealing ring and a push rod, wherein the discharge nozzle is mounted at the front end of the needle cylinder, the piston is arranged in the needle cylinder and can move freely, the sealing ring is closely combined with the rear part of the piston, and the head end of the push rod is connected with the piston. The sampling assistant tool is characterized in that: the cylinder body of the needle cylinder is provided with volume scales; the discharge nozzle is hollow and conical, the piston is also conical, and the shape and the size of the piston are completely consistent with the shape and the size of the inside of the discharge nozzle. The sampling assistant tool of the rheometer can accurately measure the sample volume according to actual dosage, and operations of firstly measuring the sample density and then weighing the sample are omitted; and simultaneously, the discharge nozzle at the front end of the needle cylinder is conical, so that the discharge nozzle can be directly inserted into a cylindrical standard sample cup with small aperture and large depth so as to directly inject the sample, and the sample is protected from transfer loss and contamination; after sampling, the discharge nozzle at the front end of the tool and the rear end of the tool can be directly detached, so that the tool is convenient to wash, and cross contamination of different samples is avoided.
Description
Technical field
The present invention relates to a kind of laboratory sampling aid, relate in particular to a kind of flow graph sampling aid.
Background technology
Flow graph is the viscosity that is used for measuring Newtonian fluid, and the recorded stream varied curve also can be measured the viscosity function of non-Newtonian fluid under constant shearing.Simultaneously, flow graph also can measure material under different shearings rate rheological property and viscoelastic body in creep process.The R/S-CC coaxial clyinder flow graph of U.S. Brookfield company, the utensil that holds sample are the right cylinder standard model cups with accurate rotor coaxial.The sample volume that is added in this sample cup during measurement has strict demand, otherwise can influence measuring accuracy.Because the density of different formulations sample also has nothing in common with each other, if adopt the way of weighing to measure sample, need first measurement products density, the operation more complicated; In addition, when the sample of needs measurement is the paste semisolid, because its viscosity ratio is higher, be difficult for the amount volume, and the amount of taking seldom needs only several milliliters at every turn, sample can produce loss and pollution when in different measurers, shifting; The right cylinder standard model rim of a cup footpath that holds sample simultaneously is little, and the degree of depth is high, and sample can only add several times, operates cumbersome.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art; A kind of simple in structure, aid of flow graph sampling cleverly is provided; Use this aid can accurately measure sample, can sample directly be transferred to right cylinder standard model cup the inside then, save the intermediate transfer process; Sample is not easy loss and pollution, and is easy and simple to handle.
According to technical scheme of the present invention: flow graph sampling aid; Comprise syringe, discharging mouth, piston, O-ring seal and push rod; The discharging mouth is installed in the syringe front end, and piston is contained in the syringe and can move freely, and O-ring seal is combined closely at the piston rear portion; Said push rod head end is connected on the piston, it is characterized in that: the stack shell of said syringe is provided with volume markings; Said discharging mouth is the open circles taper, and said piston also is conical, and the shape size of piston is in full accord with discharging mouth interior shape size.
As further improvement of the present invention, said discharging mouth is installed in the front end of syringe with the mode of detachable replacing.
As further improvement of the present invention, said piston and O-ring seal can disassemble from the syringe afterbody, so that clean.
The present invention compared with prior art, advantage is: flow graph of the present invention sampling aid can accurately be measured sample volume according to actual amount, need not the sampling of weighing again after the first test sample article density; The discharging mouth of syringe front end is conical simultaneously, can directly insert in the right cylinder standard model cup that bore is little, the degree of depth is high, and sample is directly injected, and avoids the transfer loss and the pollution of sample; After the sampling, can be directly that the discharging mouth and the rear end of instrument front end is all detachable, be convenient to clean, can avoid different sample rooms to pollute each other.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure: the flow graph sampling aid among the embodiment mainly is made up of syringe 1, discharging mouth 2, piston 3, O-ring seal 4 and push rod 5.
As shown in Figure 1, said discharging mouth 2 is the open circles taper, and discharging mouth 2 is installed in syringe 1 front end with the mode of detachable replacing; Said piston 3 is contained in the syringe 1 and can move freely, and the stack shell of syringe 1 is provided with volume markings, and piston 3 also is conical, and the shape size of piston 3 is in full accord with discharging mouth 2 interior shape sizes; Said O-ring seal 4 is combined closely at piston 3 rear portions, and said push rod 5 head ends are connected on the piston 3.Among the present invention, said piston 3 can disassemble from syringe 1 afterbody with O-ring seal 4, so that reinforced and cleaning.
During actual the use, with push rod 5 piston 3 is moved to syringe 1 rear end earlier, and guarantee the sample volume that the corresponding volume markings of piston 3 front end faces is taken greater than need; Then discharging mouth 2 is disassembled, make syringe 1 front port up, add sample from syringe 1 front port, up to flushing with syringe 1 front port; Load onto discharging mouth 2 then, promote push rod 5 forward, the sample that piston 3 is promoted in the band syringe 1 moves forward, and unnecessary sample is extruded, till piston 3 front end faces arrive the pairing volume markings of required sample size; Microcephaly with discharging mouth 2 holds in the right cylinder standard model cup rim of a cup that inserts flow graph at last, promotes push rod 5 forward, and piston 3 outside surfaces and discharging mouth 2 inner wall surface are fitted fully, so just can accurately volume required sample be put into sample cup.After finishing using, can syringe 1 afterbody and conical piston 3 and O-ring seal 4 together be unloaded cleaning, thereby avoid different sample rooms to pollute each other.
