Kana zvasvika pakuyera uye kugovera vhoriyamu chaiyo yechero mvura, mapipette akakosha munzvimbo yanhasi yerabhoritari. Zvichienderana nehukuru hwerabhoritari uye vhoriyamu inoda kupihwa, marudzi akasiyana emapipetti anowanzoshandiswa:
- Air displacement pipettes
- Positive displacement pipettes
- Metering pipettes
-Adjustable range pipettes
Muna 2020, tiri kutanga kuona mamicropipettes ekutamisa mhepo achiita basa rakakosha muhondo yekurwisa COVID-19, uye anoshandiswa kugadzirira muenzaniso wekuonekwa kwepathogen (semuenzaniso, chaiyo-nguva RT-PCR). Kazhinji, magadzirirwo maviri akasiyana anogona kushandiswa, manyorero kana mota yemhepo inotamisa pipettes.
Manual Air Displacement Pipettes vs Motorized Air Displacement Pipettes
Mumuenzaniso wepipette inotamiswa nemhepo, piston inotamiswa kumusoro kana pasi mukati mepipette kuti igadzire kumanikidza kwakashata kana kwakanaka pamhepo. Izvi zvinobvumira mushandisi kufemesa kana kuburitsa sampuli yemvura uchishandisa inoraswa pipette tip, nepo mbiru yemhepo iri mumuromo inoparadzanisa mvura kubva kune isingaraswa zvikamu zvepipette.
Kufamba kwepiston kunogona kugadzirwa kuti kuitwe nemawoko nemushandisi kana nemagetsi, kureva kuti mushandisi anofambisa piston achishandisa bhatani rinodzorwa mota.
Kuganhurirwa kwechinyorwa pipettes
Kushandiswa kwenguva refu kwepipettes yebhuku kunogona kukonzera kusagadzikana uye kunyange kukuvadza kune anoshanda. Simba rinodiwa kuburitsa zvinwiwa uye kubvisa iyo pipette tip, yakasanganiswa nekudzokorora kudzokorora mafambiro kwemaawa akati wandei, inogona kuwedzera majoini, kunyanya chigunwe, gokora, wrist, uye pfudzi, paRS (I repetitive tsandanyama strain) njodzi.
Manual pipettes inoda kuti bhatani rechigunwe ritsikidzwe kuti riburitse mvura, nepo electronic pipettes inopa ergonomics iri nani nebhatani rinokonzerwa nemagetsi mumuenzaniso uyu.
Electronic Alternatives
Mapipeti emagetsi kana emota ndiwo ergonomic dzimwe nzira dzemanyorero pipettes dzinonyatso vandudza sampuli kubuda uye kuve nechokwadi uye nekurongeka. Kusiyana nemabhatani echinyakare anodzorwa nechigunwe uye vhoriyamu gadziriso, magetsi mapipetti anouya nedhijitari interface kugadzirisa vhoriyamu uye aspirate uye kuburitsa kuburikidza nemagetsi piston.
Kusarudzwa kweMota yeElectronic Pipettes
Nokuti pipetting inowanzova danho rekutanga mu-multi-step process, chero zvisizvo kana kusakwana kunoitika pakuyera chikamu chiduku chemvura chinogona kunzwika mukati mekuita kwese, pakupedzisira kuchikanganisa zvakakwana uye nemazvo.
Chii chinonzi kururama uye kurongeka?
Kururama kunowanikwa apo pipette inopa vhoriyamu imwechete kakawanda. Kururama kunowanikwa apo pipette inopa vhoriyamu yakananga nenzira kwayo pasina kukanganisa. Kururamisa uye kururamisa kwakaoma kuwana panguva imwe chete, asi maindasitiri anoshandisa pipettes anoda zvose zvakarurama uye zvakarurama. Muchokwadi, iyi ndiyo chiyero chepamusoro-soro chinoita kuti zvikwanise kuburitsa mhinduro dzekuyedza.
Mwoyo wepipette yemagetsi ndiyo motokari yayo, iyo inonyanya kukanganisa kurongeka uye kurongeka kwepipette, kuwedzera kune zvimwe zvinhu zvinokosha zvakadai sehukuru hwepakiti, simba uye uremu. Pipette dhizaini mainjiniya anonyanya kusarudza angave anotsika mutsara actuators kana DC mota. Nekudaro ese ari maviri stepper mota uye DC mota ane zvawo zvakanakira uye zvazvakaipira.
DC Motors
DC mota dziri nyore mota dzinotenderera kana DC simba raiswa. Iwo haadi kubatanidza kwakaoma kuita kuti mota imhanye. Nekudaro, nekupihwa mutsara wekufamba zvinodiwa zvemagetsi pipettes, DC mota mhinduro dzinoda yakawedzera lead screw uye giya kushandura iyo inotenderera inofamba kuita mutsara inofamba uye kupa simba rinodiwa. DC mhinduro dzinodawo maitiro emhinduro muchimiro che optical sensor kana encoder kuti inyatso kudzora chinzvimbo chemutsara piston. Nekuda kweiyo inertia yakakwira ye rotor yayo, vamwe vagadziri vanogonawo kuwedzera braking system kuti ivandudze kumira zvakanaka.
Stepper motors
Kune rimwe divi, mainjiniya mazhinji anosarudza stepper linear actuator mhinduro nekuda kwekureruka kwavo kwekubatanidza, kuita kwakanaka uye mutengo wakaderera. Stepper linear actuators ine yekusingaperi magineti stepper motors ine yakarukwa rotor uye yakasanganiswa filament bar kuburitsa yakananga mutsara kufamba mumapakeji madiki.
