Hypodermic Syringes Laboratory Applications

Cov kws kho mob qib siab uas siv khwv yees tau siv ntau hom kabmob siv feem ntau siv rau hauv kev soj ntsuam kuaj kev tshawb nrhiav kom yooj yim thiab tsawg. Lwm daim ntawv thov yog siv rab koob ntxiv rau cov kua ntxiv kom nruj heev, xws li ntxuav tawm qee qhov kev tawm tswv yim. Lawv feem ntau siv los ntsuas thiab xa cov kuab tshuaj thiab cov tshuaj reagents qhov twg tsis muaj qhov siab tshaj. Xwb, microliter syringes siv tau los ntsuas thiab siv cov tshuaj lom neeg heev los ntawm kev siv lub me kab capillary me me ua tus syringe chim.

Kev siv hluav taws xob hauv cov nplais no yuav ua rau lawv cov kab mob uas tsis sib haum. Muaj, txawm li cas los xij, muaj feem xyuam ntawm cov khoom ntawm cov koob txhaj tshuaj syringes leaching plasticizers los ntawm cov khoom siv syringe. Cov iav tsis siv cov iav syringes kuj yuav raug xaiv dua qhov twg yog qhov teeb meem. Cov iav syringes kuj tseem yuav xav tias qhov twg yog qhov tseem ceeb heev ntawm qhov kev txiav txim siab tseem ceeb (piv txwv tias cov tshuaj tsom), vim lawv txoj kev tuaj yeem ua haujlwm tsawg dua thiab cov plungers txav ntau dua. Hauv cov ntawv no, cov ntaub ntawv ntawm cov kab mob pathogens feem ntau tsis yog qhov teeb meem.

Siv koob ntev los yog cannula, syringes kuj tseem ceeb rau kev xa cov kua qaub los ntawm rubber septa thaum atmospheric oxygen los yog ya raws raug tshem tawm. Cov piv txwv muaj xws li kev xa mus rau cov cua daj cua dub lossis cov tshuaj reagents xws li phenylmagnesium bromide thiab n-butyllithium. Cov iav koob txhaj tshuaj kuj tau siv los hno cov qauv me me rau roj chromatography (1 μl) thiab huab hwm coj spectrometry (10 μl). Syringe tsav tsheb yuav siv nrog tus syringe thiab.
