Pasteur Pipettes
Nws tseem hu ua eye droppers los yog tsuas yog droppers. Raws li txoj cai, lawv yog tsim los ntawm iav, txawm hais tias cov yas Pasteur Pipettes tau hloov pauv lawv Cov no yog tshwj xeeb rau kev kho kom haum rau kev hloov pauv ntawm cov kua me me. Cov hlab no tau koom nrog rau ntawm qhov kawg ntawm lub hnab yas lossis roj hmab qhov muag thiab taper mus rau ib qho me me ntawm qhov kawg. Teat pipette yog ib lo lus rau kev sib txuas iav Pasteur pipette thiab roj hmab qhov muag teev.
Volumetric pipettes
Nws tseem hu ua bulby pipette lossis lub plab pipette. Nws yog feem ntau siv nyob rau hauv analytical chemistry hauv kev ua cov kev daws teeb meem los ntawm cov Tshuag thiab npaj cov kev daws teeb meem rau titration. Nws lub teeb yog loj, thiab nws feem yog ntev thiab nyias. Lawv muaj txiaj ntsig zoo tshaj plaws rau kev ntsuas ceev vim tias lawv tuaj yeem ntsuas ntsuas kom muab cov kua dej meej meej nrog qhov tseeb txog li 4 tus lej tseem ceeb.
Kawm tiav pipettes
Kawm tiav pipettes yog cov uas tau qhia qhov ntim nce ntxiv nrog rau lub raj. Cov pipettes, uas tuaj nyob rau hauv ntau yam duab, yog nquag ua hauj lwm rau ncaj qha kev daws teeb meem. Lawv feem ntau muaj lub taub hau thiab yog tsim los ntawm iav los yog yas muaj zog. Cov tub ntxhais kawm tiav tuaj yeem muab faib ua Hom 1, Hom 2, thiab Hom 3 raws li lawv qhov kev tsim kho. Txhua qhov ntim ntawm hom 1 pipettes muaj qee qhov kev daws teeb meem. Hauv qhov sib piv, hom 2 pipettes muaj xoom nyob rau hauv qab thiab tus nqi nominal nyob rau saum toj, thiab hom 3 pipettes tsuas yog muab cov kev daws teeb meem ntawm tus nqi nominal. Mohr pipettes thiab serological pipettes yog ob pawg tseem ceeb ntawm kev kawm tiav pipettes.
i) Serological pipettes
Cov no yog siv nyob rau hauv lub chaw soj nstuam rau maj mam sib tov ntawm cell suspensions, reagents, thiab tshuaj tov tshuaj, tsim gradients nyob rau hauv reagent txheej, hloov kua (ob peb mL mus rau 100 mL), thiab volumetric ntsuas. Serological pipettes ua rau nws muaj peev xwm rau cov hlwb kom sib npaug thoob plaws hauv kev daws teeb meem, uas yog qhov tseem ceeb rau kev coj noj coj ua ntawm tes.
ii) Mohr's pipettes
Qhov ntsuas ntawm Mohr pipette muab faib ua ib feem ntawm ib thiab ib feem kaum ntawm ib milliliter. Nws tsis tshua muaj tseeb dua li lub ntim ntim dej vim nws lub caj dab dav. Thaum noj ntau qhov kev daws teeb meem uas qhov tseeb tsis yog qhov tseem ceeb, lawv tau siv. Lawv tuaj yeem tso kua dej maj mam thiab tau ntim zoo ib yam li cov ntim ntim.
iii) Hloov pipettes
Cov no yog cov pov tseg hloov pipettes, ib qho ntawm cov pipettes kawm tiav uas ua haujlwm zoo rau Pasteur pipettes vim tias ib tus yuav tsum tsis txhob txhawj xeeb ntxiv txog qhov phom sij ntawm cov iav tawg thiab kev sib kis ntawm cov qauv. Lawv ua hauj lwm hauv cov txhab nyiaj ntshav, urinalysis, ntub chemistry, microbiology, hematology, thiab serology. Qhov qis affinity ntawm unbreakable tsawg-ceev polyethylene yas ntawm cov pipettes txo qis vim tias lawv tau ua kua rau roj ntsha thiab cov acids.
Vacuum-pab Pipettes
Ob leeg muab qhab nia thiab volumetric nqus-pab pipettes muaj. Thaum volumetric nqus-pab pipettes tsuas ntsuas ib lub ntim thiab li no tsuas muaj ib qho kev kawm tiav, kawm tiav nqus-pab pipettes siv ntau yam kawm tiav. Polystyrene, iav, los yog borosilicate yog siv los tsim lub tshuab nqus tsev pipettes. Lawv tsis muaj pistons tab sis xav tau lub tshuab nqus tsev.
Repeater pipette
Repeater pipettes yog zoo meej rau dispensing tib qhov ntau dua rau hauv ob peb receptacles yam tsis muaj ncua nyob rau hauv nruab nrab ntawm txhua tus txheej txheem dispensing, txhim khu kev ceev thiab efficiency. Cov no yog lub teeb yuag thiab tsuas yog xav tau ib txhais tes los ua haujlwm, ua rau ib tus neeg teb xov tooj ua haujlwm ntawm lub peev xwm dhau los.
Ib channel pipettes Vs. Multichannel pipettes
Ib qho channel pipette yog ib qho khoom siv uas tsis yog siv pov tseg nrog cov qauv tsim huab cua uas ua kom muaj kev ntsuas qhov tseeb uas siv ib lub taub pov tseg. Multichannel pipette yog piv rau ib leeg-channel pipette, tshwj tsis yog nws yuav tuav tau ntau lub tswv yim ib txhij. Cov kua yog aspirated ib txhij los ntawm tib lub qhov dej mus rau ntau txoj kev.
Ob qho tib si phau ntawv thiab hluav taws xob ib leeg-channel sib txawv ntim thiab cov ntim ntim ruaj khov yog muab, qhov twg phau ntawv yog qhov kev lag luam tshaj plaws thiab cov qauv tsim. Hauv qhov sib piv, lub tshuab hluav taws xob micropipette yog kim thiab muaj ntau qhov zoo, xws li kev txhim kho ergonomics, tsawg dua cov neeg siv-rau-tus neeg siv sib txawv, thiab ntau qhov tseeb thiab qhov tseeb.
Phau ntawv Vs. Electronic pipette
Ib phau ntawv pipette siv lub zog txhua yam ntawm tus ntiv tes xoo kom txav lub piston (txog 3cm), thaum cov kav dej hluav taws xob tau tsim los txhim kho ergonomics los ntawm kev txo qhov tsim nyog quab yuam. Electronic pipettes yog li hloov lub roj teeb me me uas siv hluav taws xob lub cev muaj zog rau kev siv phau ntawv.
Tsau Vs. adjustable ntim pipette
Taag-volume pipettes yog qhov zoo tshaj plaws rau kev ua haujlwm nrog cov kua dej ntom ntom lossis cov kua nplaum. Lub pipette lub ntim tsis tuaj yeem hloov pauv hauv lub ntim ntim ruaj khov uas ua rau tus neeg siv ua haujlwm sai dua yam tsis tas yuav kho lub ntim ntau zaus. Nyob rau hauv sib piv, ib tug kho ntim pipette muaj lub vo
lume hloov qhov chaw ntawm sab lossis sab saum toj. Yog li, lub ntim ntim ruaj khov tsis tshua muaj kev ua yuam kev, thiab nws cov calibration yog qhov yooj yim dua thiab nrawm dua li qhov hloov tau ntim pipette.
Lub hom phiaj tshwj xeeb pipette
Cov pipettes no yog tsim los rau cov hom phiaj tshwj xeeb, xws li kev tsom xam cov tshuaj hormones ib puag ncig nrog iav taub Micropipettes thiab cov ntim siab ultra macro-pipettes nrog lub peev xwm ntawm 50- milliliter ntim dispensing. Van Slyke pipettes, Ostwald-Folin pipettes, iav micropipettes, microfluidic pipettes, thiab tsis tshua muaj ntim pipettes yog ob peb yam piv txwv ntawm tshwj xeeb pipettes.
