Kas yra the principas of refraktometras dizainas?
Refraktometrai yra suprojektuoti pagrįsta on the principle that liquids of different concentrations have different refractive indexes. It can detect the globulin content in colostrum. It has the advantages of fast, accurate, light weight, easy operation and portability, clear vision, and small size.
A refraktometras is an instrumentas kad gali aptikti the refractive index ND and average dispersion NF-NC of transparent, translucent liquids or solids. Since different substances have specific refractive indexes, the instrument can detect material properties pagal to different states. Todėl, the detection results of the refractometer are often used as a basis for detecting the concentration and purity of raw materials, solvents, intermediates and final products, and for identification unknown samples. , has become one of the indispensable common equipment in scientific research units, ypač in the pharmaceutical field.
Instrukcijos:
Open the cover and wipe the detection prism with a clean flanel;
Use a dropper to take 1-2} drops of the solution to be tested, drop it on the detection prism, and gentley cover the cover. If need, press the cover gently to make the solution toly distributed on the prism to avoid the generation of bubbles;
Laikykite the black rubber part of the instrument, face it to a bright place, and keep the instrument as parallel to the ground as possible (do not tilt it up or fall down). Observe the scale inside through the okuliaras. If it is not clear, slow fine-tune the okuliaras reguliavimas ranka. ratas iki the scale can clear seen;
At this time, you can clear see the blue and white didaling line inside the instrument. The scale value of the dividing line is the concentration of the solution.
Refraktometras Pastabos:
Tai instrumentas yra a tikslumas optinis instrumentas. Metu naudojimas ir priežiūra, the following matters should be paid attention to:
During use, you must be careful and use it strictly accord to the instructions. Do not loosen the connecting parts of the instrument at will. Do not drop, collide, or violently vibrate.
Po naudojimo, it is griežtai draudžiama to put it tiesiogiai į vandenį for valymui. Naudojimas a švarus minkštas aksomas šluostė panardintas į vandenį to nuvalyti it išvalyti. Paviršius iš optinių dalių turėtų ne būti subraižytas arba subraižytas.
instrumentas turėtų būti saugomas in a sausas vieta laisvas iš dulkių, alyva, rūgštis ir kita ėsdinančios dujos to prevencijos optinės dalys nuo būti korozija arba pelėsis.
