Plastic Centrifugal Tube Sauƙaƙa Kuma Kyawun Kyawun Centrifugal Don Amfanin Laboratory
Lokacin zabar wannan batu, ya kamata mu kuma mai da hankali don bincika ko murfin bututu yana da ƙarfi, kuma ko ana iya rufe shi sosai yayin gwajin don isa jujjuyawar ba tare da yabo ba; Dukanmu mun san cewa a cikin bututun centrifugal na filastik, kayan da aka saba amfani da su sune polyethylene, polycarbonate, polypropylene, da sauransu, wanda bututun polypropylene PP za su sami kyakkyawan aiki, don haka muna la'akari da bututun filastik na centrifugal na polypropylene kamar yadda zai yiwu yayin zabar bututun centrifugal filastik.
A, PA: polymer isocrystalline; PC polycarbonate; PP: tsaftacewa na polypropylene
B, Bututun centrifugal na PC da kofuna: Kayan PC suna da ƙarancin kwanciyar hankali na sinadarai zuwa abubuwan kaushi na alkaline, kuma dole ne a guji abubuwan tsaftacewa tare da ƙimar PH sama da 9. Autoclaving na
C, PA, PC and PP centrifuge tubes and cups: PA begins to soften at 120°C, while PC and PP are at 130°C. Typically, PA can be sterilized at 115°C (0.7kg/cm²) for 30 minutes, while PC and PP can be sterilized at 121°C (1.0kg/cm²) for 20 minutes. If the temperature is too high, the centrifugal tube or cup will be deformed. When using sterilized utensils, follow the following operations:
(1) Sanya bakin bututu zuwa sama da a tsaye; Idan bututun ya karkata ko sanya shi a gefe, zai lalace saboda nauyi;
(2) Cire hular da aka zare da hular ciki don hana bututun daga lalacewa ko tsagewa;
(3) Za a iya fitar da bututun ne kawai lokacin da aka saukar da bakararre zuwa zafin jiki;
D, rayuwar centrifugal tube da kofin Rayuwar filastik centrifugal tube kofin dogara da samfurin halaye, rotor gudun, centrifugal zafin jiki, da dai sauransu Lokacin da filastik centrifugal tubes da kofuna waɗanda ake amfani da centrifuge na al'ada tsaka tsaki samfurori (PH5 ~ PH9), Kididdigar rayuwarsu kamar haka: ana amfani da su a cikin mafi girman gudu: kusan sau 10 (amfani da ƙarancin gudu yana iya ƙara yawan amfani). Rayuwar bututun centrifuge da kofuna kuma suna da alaƙa da yanayin tsaftacewa da lalata.
Centrifuge bututu wani akwati ne da ake amfani da shi don ɗaukar samfuran da aka keɓe lokacin da centrifuge ke sarrafa samfuran, kuma ƙayyadaddun sa sun fi 0.2ml, 0.5ml, 1.5ml, 2ml, 5ml, 7ml, 10ml, 15ml, 20ml, 50ml, 80ml, 100ml.
Amfanin bututun centrifugal na filastik yana da haske ko mai jujjuyawa, taurinsa kadan ne, kuma ana iya fitar da samfurin ta huda. Rashin lahani shine nakasawa mai sauƙi, rashin juriyar lalata ga kaushi, da gajeriyar rayuwar sabis. Bututun centrifugal na filastik suna da murfin bututu, wanda ake amfani da shi don hana ɗigon samfurin, musamman ga samfuran rediyoaktif ko masu lalata sosai don hana ɗigon samfurin abu ne mai mahimmanci; Wani aiki na murfin bututu shine don hana samfurin volatilization da goyan bayan bututun centrifugal don hana nakasar bututun centrifugal.
Lokacin zabar wannan batu, ya kamata mu kuma mai da hankali don bincika ko murfin bututu yana da ƙarfi, kuma ko ana iya rufe shi sosai yayin gwajin don isa jujjuyawar ba tare da yabo ba; Dukanmu mun san cewa a cikin bututun centrifugal na filastik, kayan da aka saba amfani da su sune polyethylene xi (PE), polycarbonate (PC), polypropylene (PP), da sauransu, wanda bututun polypropylene PP zasu sami kyakkyawan aiki, don haka yakamata muyi la'akari da polypropylene filastik centrifugal. bututu gwargwadon yiwuwa lokacin zabar bututun centrifugal na filastik.
