Tips, kamar yadda ake amfani da su tare da pipettes, gabaɗaya ana iya raba su zuwa: ①. Tace tukwici, ②. Daidaitaccen shawarwari, ③. Low adsorption tips, ④. Babu tushen zafi, da sauransu.
1. Tushen tacewa abin amfani ne da aka ƙera don guje wa gurɓacewar giciye. Ana amfani da shi sau da yawa a gwaje-gwaje kamar ilmin kwayoyin halitta, cytology, da virology.
2. Standard tip shine mafi yawan amfani da tip. Kusan duk ayyukan bututun na iya amfani da tip na yau da kullun, wanda shine mafi kyawun nau'in tukwici.
3. Don gwaje-gwaje tare da buƙatun hankali masu girma, ko samfurori masu daraja ko reagents waɗanda suke da sauƙin zama, za ku iya zaɓar ƙananan tallan tallan don ƙara yawan dawowa. Fuskar ƙananan tip ɗin adsorption an yi amfani da maganin hydrophobic, wanda zai iya rage ƙananan ruwa na tashin hankali yana barin ƙarin ragowar a cikin tip. (Hoton bai cika ba kuma ƙwaƙwalwar ajiyar tana iyakance)
PS: Tushen bakin-fadi yana da kyau don tsotsa kayan danko, DNA na genomic, da ruwan al'adun tantanin halitta;
Ma'anar aiki na tip: ƙananan adsorption, nau'in tacewa, ƙuntatawa, ƙarfin lodi da fitarwa, babu DNase da RNase, babu pyrogen;
Yadda za a zabi mai kyau tip? "Idan dai tip ɗin da za a iya shigar shine tip ɗin da za a iya amfani da shi"
——Wannan ita ce cikakkiyar fahimtar kusan duk masu amfani akan daidaitawar shugaban tsotsa. Wannan magana za a iya cewa wani bangare na gaskiya ne amma ba gaskiya ba ce gaba daya.
Tushen da za a iya sakawa a kan pipette zai iya samar da tsarin tsarin pipette tare da pipette don gane aikin pipetting, amma wannan abin dogara ne? Ana buƙatar alamar tambaya anan. Amsa wannan tambayar yana buƙatar bayanai don yin magana.
1. Kuna iya yin gwajin aiki bayan daidaita pipette tare da tip. Bayan kurkura tip, aiwatar da ayyuka da yawa na ƙari na samfurin, auna adadin adadin samfurin kowane lokaci, da rikodin karatun.
2. Yi ƙididdige daidaito da daidaiton aikin bututun bayan an canza shi zuwa ƙarar gwargwadon ƙimar gwajin gwajin.
3. Abin da za mu zaɓa shine tip tare da daidaito mai kyau. Idan daidaiton pipette da tip ɗin ba su da kyau, yana nufin cewa ba za a iya tabbatar da matsi na tip da pipette ba, don haka ba za a iya sake haifar da sakamakon kowane aiki ba.
Don haka menene mafi ƙarancin maki don kyakkyawan tip?
Kyakkyawan tip ya dogara ne akan ƙaddamarwa, taper, kuma mafi mahimmancin batu shine adsorption;
1. Bari muyi magana game da taper da farko: idan ya fi kyau, wasan da bindiga zai yi kyau sosai, kuma shayarwar ruwa zai zama mafi daidai;
2. Mahimmanci: Ƙaddamarwa shine ko da'irar da ke tsakanin tip na tip da haɗin tsakanin tip da pipette shine cibiyar guda ɗaya. Idan ba cibiyar ɗaya ba ce, yana nufin cewa ƙaddamarwa ba ta da kyau;
3. A ƙarshe, mafi mahimmanci shine ƙaddamarwar mu: adsorptivity yana da alaƙa da kayan tip. Idan abu na tip ba shi da kyau, zai shafi daidaito na pipetting, wanda zai haifar da babban adadin ruwa ko raguwa Don rataye a bango, haifar da kurakurai a cikin pipetting;
Don haka ya kamata kowa ya kula da wadannan abubuwa guda uku na sama yayin zabar kan tsotsa
