转头配套适配器、离心管见:［订购信息］

VTi 50.1垂直转头，最大离心容量12×39mL。转子产生离心力，可以用于DNA或病毒颗粒的密度梯度分离。适用于贝克曼Optima XPN-100/XPN-90/XPN-80系列高端立式超速离心机和Optima XE-100/XE-90系列基础型超速离心机。

1、转头的组成

VTi 50.1垂直转头由钛合金制成，并涂有黑色聚氨酯（polyurethane）漆。

Quick-Seal和OptiSeal两款离心管，需添加管盖状的管帽适配器/垫片（tube spacer）对离心管上部提供支撑，避免在强大水平离心力作用下，离心管上部变形。透明适配器用于Quick-Seal快封管，金色阳极氧化铝材质适配器用于OptiSeal管。

超速离心机运行中，为避免因离心管内残留少量空气因直接暴露于离心腔体的真空环境而过度膨胀、离心管变形引发样品泄漏风险，需将离心孔内的气压维持在实验室正常气压水平。转头标配的红色阳极氧化铝材质六边形转头塞（hex-cavity rotor plug）与密封垫圈（plug gasket），用于有效密封离心孔，将离心管与离心腔真空环境有效隔离。

为了防止超速，超速离心机中的光电探测器会监测转子底部的超速盘，如果检测到速度超过额度转速，则会自动关闭运行。
