ning ko'p turlari mavjud. Turli xil hujayra madaniyati ehtiyojlariga ko'ra, qopqoqlarning ko'p turlari mavjud. Xo'sh, hujayra madaniyati kolbalarining qopqog'ini qanday tanlash kerak? Hujayra madaniyati kolbalarining qopqoqlari odatda ichki prokladkalarsiz yopiladi. Ularning havo o'tkazmasligini ta'minlash uchun ular ko'pincha yopiq madaniyat uchun ishlatiladi. Qopqoq bo'shatilganda, u ochiq madaniyat uchun ham ishlatilishi mumkin. Bundan tashqari, kulbalarning qopqoqlarida shamollatuvchi qopqoqlar, septum qopqoqlar, poliester qopqoqlar va boshqa turlar ham mavjud. hujayra madaniyati kolbalari
Nafas oladigan qopqoq steril gaz almashinuvini ta'minlash va zararlanish xavfini kamaytirish uchun shisha qopqog'iga qo'shilgan 0,2 mkm hidrofobik filtrli membranadir. ifloslanish. Odatda ochiq kultura uchun ishlatiladi, CO2 inkubator madaniyati uchun tavsiya etiladi, ayniqsa uzoq muddatli ekishni talab qiladigan tajribalar uchun.
Septum qopqog'i septumda oldindan kesilgan teshikka ega, shuning uchun so'rg'ich (yoki 5ml pipetka yoki pipetka) kamroq) suyuqlik qo'shish, aspiratsiya suyuqligi yoki hujayralarni yig'ish, ifloslanish ehtimolini kamaytirish va kultura shishasini yopiq saqlash uchun septum orqali kiritilishi mumkin. bo'shashgan) va shishadagi gaz qopqoqni muloyimlik bilan bo'shatish orqali atrof-muhitdagi gaz bilan almashtirilishi mumkin.
Turli xil qopqoq turlari
