Spectrophotometric cuvettes muaj kab sib txawv ua ke rau hauv cov khob, khob, thiab khob yas raws li cov khoom siv. Raws li qhov ntsuas ntau, muaj cov cuvettes thiab capillary cuvettes. Qhov kev ntsuam xyuas dav dav nucleic acid thiab kua qaub qes noj ultraviolet tau siv quartz khob los sis iav, tab sis nws tsis haum rau qhov kev txiav txim siab colorimetric. Vim tias cov dyes hauv cov tshuaj tiv thaiv (xws li Coomassie ci ntsa iab) yuav xim xim quartz thiab iav, siv cov khob yas uas siv tas. Cov khob yas yog feem ntau tsis tsim los kuaj kev kuaj hauv cov UV.
Vim yog qhov sib txawv ntawm tus nqi kuaj tau kuaj, cov neeg muag khoom spectrophotometer feem ntau muab ntau qhov sib txawv ntawm cov cuvettes kom tau raws li cov kev xav tau ntawm cov neeg siv. Muaj ib lub hnab yas hauv lub khw uas siv tau rau nucleic acid, UV protein ntau, thiab xim proteinim. Tus nqi ntawm cov qauv no tsuas yog 50μl. Lub cuvette aseptically ntim thiab tuaj yeem siv tau. Xws li tus Eppendorf UVette & reg; yas cuvette, yog ib qho kev hloov tshiab hauv kev lag luam cuv. Nrog rau kev kawm txog lub neej yawg thiab lwm yam kev kawm, cov kev cai siab dua yog muab tso rau kev sim tshawb fawb ntawm cov kev kawm. Tus spectrophotometer yuav yog ib qho txiaj ntsim zoo rau lub chaw kuaj dej molecular biology, thiab tseem yuav tsim nyog rau cov chaw soj ntsuam kab mob microbiology, khoom noj khoom haus, thiab tshuaj. Ib qho ntawm cov khoom siv.
Nrog rau kev paub txog science thiab technology, lub cuvette tsis yog ib yam tseem ceeb rau spectrophotometers. Tus ND1000 spectrophotometer manufactured los ntawm Nanodrop International yuav muab piv nrog cov qub spectrophotometer , nws yuav ua tau tsis tau diluting tus qauv, tsis siv lub cuvette, tsuas 1-2μl qauv uas yuav tsum muaj rau txhua qhov kev ntsuas. Kev ntsuas yuav raug ua tiav.
Lub tuam txhab tshwj xeeb hauv kev muag khoom ntawm spectrophotometers , txais tos cov neeg siv khoom uas muaj qhov xav tau los tham nrog thiab yuav khoom, peb yuav muab koj nrog sincere cov kev pab cuam thiab cov khoom zoo, nrog rau cov nqi qis dua.
