Hom Serological Pipettes thiab lawv siv
Serological pipettes yog siv nyob rau hauv lub laboratory los hloov cov kua. Cov pipettes no muaj kev kawm tiav nyob rau sab los pab ntsuas cov kua (hauv milliliters lossis milliliters) kom muab faib los yog aspirated. Lawv feem ntau pom zoo vim tias lawv yog cov meej heev hauv kev ntsuas qhov tsawg tshaj plaws incremental theem.
Serological pipettes feem ntau yog siv rau hauv cov hauv qab no:
kev sib xyaw ua ke;
khi reagents thiab tshuaj daws teeb meem;
Hloov cov hlwb rau kev tsom xam lossis nthuav dav;
Layered reagents los tsim cov gradients siab dua;
Serological pipettes yog tsim los siv los ua tshuab tshuab, cov pipettes no kawm tiav nyob ze ntawm lub taub hau thiab ib lub pob roj hmab uas txuas rau lub taub hau yog siv los tshuab tawm ntau dhau los ntawm kev siv cua lossis lub ntiajteb txawj nqus.
Feem ntau, tshuab tawm cov kav dej yog cim nrog lub nplhaib ob npaug, thiab kev tuav yuav tsum siv lub teeb txuas uas siv cov cua siab kom tshuab tawm thiab ntes txhua cov kua hauv nws. Ntawm qhov tod tes, ib leeg-loop pipettes yog "tsis-tawm-tawm" variants uas tso cai rau tag nrho lub taub hau kom huv.
Dab tsi yog qhov txawv ntawm serological pipettes?
Pipettes feem ntau yog ua los ntawm iav los yog yas. Rau kev nyab xeeb thiab huv si, nws yog qhov zoo tshaj plaws los siv cov polystyrene yas serological pipettes pov tseg.
Serological pipettes muab faib ua peb hom:
1. Qhib-kawg pipettes
Open-ended pipettes nrog rau qhov kawg yog qhov zoo tagnrho rau kev ntsuas cov kua dej khov heev. Lub pipette lub ntim ceev thiab tso tawm tus nqi ua rau nws zoo tagnrho rau kev tuav cov kua dej xws li roj, pleev xim, tshuaj pleev ib ce thiab sludge.
Lub pipette kuj tseem muaj lub tshuab lim fiber ntau uas pab txo cov dej paug. Slotted pipettes yog cov tsis muaj pyrogen pipettes uas yog gamma sterilized. Lawv raug muab qhwv rau hauv daim ntawv thermoformed / yas los tiv thaiv kev puas tsuaj.
Cov pipettes no muaj nyob rau hauv 1 ml, 2 ml, 5 ml thiab 10 ml qhov ntau thiab tsawg. Lawv yuav tsum ua tau raws li ASTM E1380 tus qauv kev lag luam.
2. Cov kab mob kab mob
Bacterial pipettes yog tsim tshwj xeeb rau kev kuaj mis nyuj thiab lwm yam khoom siv mis nyuj. Cov kua mis polystyrene no muaj nyob rau hauv 1.1ml thiab 2.2ml qhov ntau thiab tsawg.
Cov no yog cov tsis-pyrogenic pov tseg pipettes sterilized siv gamma hluav taws xob. Lawv tau ntim rau hauv cov ntawv thermoformed / yas kom tsis txhob muaj kev puas tsuaj. Cov pipettes no suav nrog cov lim fiber ntau los tiv thaiv kev sib kis ntawm cov kua dej thiab cov qauv ua kua. Cov kab mob kab mob yuav tsum ua tau raws li ASTM E934 thiab raug ntsuas kom muab ntxiv rau /-2 feem pua (TD).
3. Cov quav
Lub pipette yog pob tshab kiag li thiab tsis muaj kev kawm tiav. Lawv tau tsim tshwj xeeb los hloov thiab sib tov cov kua hauv ntau daim ntawv thov xws li lub tshuab nqus tsev lossis pipette aspiration txheej txheem. Lawv yog ib leeg-siv, tsis muaj pyrogen, tsis-clogging polystyrene pipettes.
Cov pipettes no yog qhwv hauv cov yas thermoformed kom tsis txhob muaj kab mob. Lawv raug sterilized siv gamma hluav taws xob thiab ua raws li Sterility Assurance Level (SAL).
Kuv nyeem cov ntim thiab ntsuas li cas siv lub serological pipette?
Nws yog ib qho tseem ceeb uas cov neeg ua haujlwm serological pipettes muaj kev paub ntau txog kev nyeem ntawv ntim thiab ntsuas cov kua hauv lawv. Muaj ob peb yam uas yuav tsum nco ntsoov thaum ua qhov no:
Tom qab thauj cov pipette, yuav tsum tau them nyiaj mloog mus rau hauv qab ntawm lub meniscus. Ib tug meniscus tsim nyob rau sab saum toj ntawm cov kua kem.
Ua tib zoo saib lub pipette ntawm qhov muag kom nyeem tau qhov tseeb.
Lub pipette yuav tsum tuav raws nraim ntawm txoj cai kaum rau hauv pem teb.
Yuav ua li cas muab cov kua thiab aspirate nrog ib tug serological pipette?
Thawj txoj kev hloov cov kua los ntawm lub qhov ncauj straws yog tsis pom zoo vim hais tias cov neeg siv tej zaum yuav yuam kev haus dej tsis zoo.
Txawm li cas los xij, nws muaj kev nyab xeeb siv lub teeb los yog lub twj tso kua mis. Qhov muag teev yog siv los xa cov kua dej tsawg dua, thaum lub twj tso kua mis pab xa cov kua dej meej. Muaj ob qhov ua rau hauv lub twj tso kua mis; ib qho rau dispensing thiab lwm yam rau aspiration.
Dab tsi yog qhov txiaj ntsig ntawm kev siv serological pipette?
Qee qhov txiaj ntsig ntawm kev siv serological pipette muaj xws li:
Lawv yog optically optimized;
Lawv muab kev txhim kho ntim raug;
Lawv muab cov nplai ascending thiab nqis;
Serological pipettes yog siv ib zaug thiab ua ntej kom tsis muaj menyuam, lawv tau ntim rau hauv qhov ntau ntawm 25 txog 50 thiab tsim kom haum rau cov kav dej hluav taws xob thiab cov khoom siv pipette.
Serological yas pipettes yog sterile consumables uas ua kom cov kua dispensing kom raug thaum txo txoj kev kis kab mob. Peb cia siab tias qhov saum toj no tau muab cov ntaub ntawv txaus rau koj txog ntau hom thiab kev siv serological pipettes.
