詳細(xì)描述
VTi 65.1垂直轉(zhuǎn)頭特別適用于在氯化銫-溴化乙錠梯度中分離封閉的環(huán)狀質(zhì)粒 DNA 和線性 DNA。RNA會沉淀;蛋白質(zhì)和其他在CsCl中浮力密度低的細(xì)胞成分會漂浮。超螺旋質(zhì)粒將在試管的中心區(qū)域帶狀,起始 CsCl 密度約為 1.55 g/mL。在典型的樣品上樣下,質(zhì)粒條帶不會與沉淀或漂浮的樣品組分接觸。適用于貝克曼Optima XPN-100/XPN-90/XPN-80系列高端立式超速離心機和Optima XE-100/XE-90系列基礎(chǔ)型超速離心機。
1、轉(zhuǎn)頭的組件
轉(zhuǎn)頭由鈦合金制成,并涂有黑色聚氨酯(polyurethane)漆。
Quick-Seal和OptiSeal兩款離心管,需添加管蓋狀的管帽適配器/墊片(tube spacer)對離心管上部提供支撐,避免在強大水平離心力作用下,離心管上部變形。藍(lán)色適配器用于Quick-Seal快封管,金色適配器用于OptiSeal管。
超速離心機運行中,為避免因離心管內(nèi)殘留少量空氣因直接暴露于離心腔體的真空環(huán)境而過度膨脹、離心管變形引發(fā)樣品泄漏風(fēng)險,需將離心孔內(nèi)的氣壓維持在實驗室正常氣壓水平。轉(zhuǎn)頭標(biāo)配的黑色陽極氧化鋁材質(zhì)六邊形轉(zhuǎn)頭塞(hex-cavity rotor plug)與密封墊圈(plug gasket),用于有效密封離心孔,將離心管與離心腔真空環(huán)境有效隔離。
為了防止超速,超速離心機中的光電探測器會監(jiān)測轉(zhuǎn)子底部的超速盤,如果檢測到速度超過額度轉(zhuǎn)速,則會自動關(guān)閉運行。
