Description
Technical field
The utility model relates to a kind of medical graduated cylinder, belongs to medical fluid graduated cylinder field.
Background technology
Graduated cylinder is used to a kind of glass apparatus measuring liquid.Graduated cylinder is the instrument measuring liquid volume.Specification represents with the max cap. that can measure (ml), and conventional has 10ml, 25ml, 50ml, 100ml, 250ml, 500ml, 1000ml etc.Outer wall scale is all in units of ml, the every little lattice of 10ml amount letter represent 0.2ml, and the every little lattice of 50ml graduated cylinder represent 1ml, visible graduated cylinder is larger, and caliber is thicker, and its degree of accuracy is less, the reading error caused by the deviation of sight line is also larger, according to the volume of got solution, should select the graduated cylinder of the minimum gauge that can once measure in experiment, gradation measures and also can cause error as far as possible.As measured 70ml liquid, should select 100ml graduated cylinder, measurement cylinder reading is to one decimal place.
For the cylindrical shape of perpendicular length, on have mouth along side, be convenient to topple over.There is wide pin bottom to keep stable.Cylindrical wall is carved with volume range, reads volume for user.Maximum measurement volume is from several milliliters to a few liter.Barrel is printed on scale from bottom to top.During observed reading, it is equal with the lowest part (or highest point of meniscus) of the concave meniscus of liquid that experimenter will notice that sight line needs, the container being used for surveying liquid volume also has calibrated pipet, transfer pipet and dropper, and the above two are all high than the accuracy of graduated cylinder.But a transfer pipet once can only measure the solution of fixed amount, calibrated pipet can measure the scale amount of needs, and dropper is more loaded down with trivial details on using, and also relative accuracy is poor, is generally used for pipette roughly, as developer, damping fluid etc.
When injecting liquid in graduated cylinder, application left hand arrests graduated cylinder, and graduated cylinder is slightly tilted, and the right hand takes reagent bottle, makes graduated cylinder bottleneck be close to graduated cylinder mouth, liquid is slowly flowed into.When amount to be implanted is slightly fewer than required amount, graduated cylinder is set level, use glue head dropper instead and be added drop-wise to required amount.When quantity of fluid, the appropriate graduated cylinder of size (otherwise larger error can be caused) will be selected according to measured volume, graduated cylinder vertically steadily should be put on the table during reading, and make the minimum point of the liquid concave meniscus in the scale of graduated cylinder and graduated cylinder remain on same level.In general graduated cylinder is that diameter is more thin better, and such degree of accuracy is higher, because the area of circle can only calculate rough number, so diameter is larger, error is larger.
Current existing medical use liquid graduated cylinder is all that the scale having 10ml, 25ml, 50ml, 100ml, 250ml, 500ml, 1000ml such represents, can not just just in the position of these scales but unavoidably have surplus liquid, and this just needs the naked eyes identification of people.In naked eyes identifying, one is to cause excess eye-using two to be that meeting is easily read wrong, causes experimental error.
Utility model content
