VTi 50.1垂直轉頭，最大離心容量12×39mL。轉子產(chǎn)生離心力，可以用于DNA或病毒顆粒的密度梯度分離。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系列基礎型超速離心機。
1、轉頭的組成
VTi 50.1垂直轉頭由鈦合金制成，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。透明適配器用于Quick-Seal快封管，金色陽極氧化鋁材質適配器用于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)樣品泄漏風險，需將離心孔內(nèi)的氣壓維持在實驗室正常氣壓水平。轉頭標配的紅色陽極氧化鋁材質六邊形轉頭塞（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)測轉子底部的超速盤，如果檢測到速度超過額度轉速，則會自動關閉運行。
