Autovial™非针头式滤器是一种预装的滤器，用于除去样品中的微粒。它用一个简单、一次性的装置代替了注射器和过滤器的组合。
Autovial滤器由2部分组成：一个逐层过滤筒和一个活塞，可过滤5-12ml样品。
Autovial可根据应用选择滤膜。样品可以被注入5ml或12ml的过滤筒，推动活塞直到过滤筒底部，在活塞和样品之间有一个空气层。将Autovial的头部置于自动加样器小瓶或容器口，推动活塞，可直接将滤除液收集，然后在仪器上操作。
特点·一体化装置省时，不用安装，方便操作·可选过滤介质，应用于不同样品·可用于有害样品，一体化设计避免了滤器突然脱离的风险·内置排气设计，*大化样品回收·可选无菌包装·独特的预滤设计，可用于难于过滤的样品（Autovial 5中无预滤器，Autovial 12可选预滤器）·可选玻璃纤维或聚丙烯预滤器
根据应用不同，可选不同的Autovial滤膜·醋酸纤维素（CA）：低非特异性蛋白结合、高载量膜，用于生物溶液·玻璃微纤维（GMF）：深度过滤，水相或有机相溶液·尼龙（NYL）：水相或有机相样品，pH3-10·聚醚砜（PES）：低非特异性蛋白结合膜，用于水相溶液·聚丙烯（PP）：疏水膜，抗大多数有机溶剂·聚四氟乙烯（PTFE）：Teflon膜，用于50%以上的有机溶剂·聚偏二氟乙烯（PVDF）：低非特异性蛋白结合膜，用于水相溶液或有机溶剂

Autovial devices are comprised of two parts: a graduated filter barrel and a plunger. The proven design features an integral filter, built-in air purge and a support stand that protects the recessed slip-luer tip. They are available in a 5 ml and 12 ml volume capacity.
The Autovial filter is selected according to membrane compatibility with the sample. In practice, the sample is poured into the 5 ml or 12 ml capacity filter barrel. The plunger is inserted into the barrel until the bottom is securely in place; there is a gap of air between the sample and plunger. Then, the tip of the Autovial is placed into the mouth of an autosampler vial or container and the plunger compressed. Filtration begins immediately and, as the plunger is compressed until it reaches the bottom, the membrane is purged with air for maximum sample recovery. For direct instrument injection, a needle is placed on the Autovial slip-luer outlet.
