用于测量油酯标准，油酯分离采样器专门为采集润滑油酯和油脂样品设计，不适用于固体或者半固体采样。内径尺寸3.5cm，可以用于小颗粒食品样品的采样。透明管容易测量样品的标准，一英尺处红色标记表示油酯的积累量。使用的时候打开阀门，接触样品，液体样品即可流进管内。关闭阀门，提起采样器，所采集的液体样品便被保存在采样器中，打开阀门，采样器中的样品便会自动流出到准备好的容器中。采样器由两段长1.22m的管子用螺丝拧在一起。上海瑞亿仪器有限公司
For measuring the grease level in a holding tank, the grease trap sampler is designed for sampling liquid grease and oils. It will not work with solid or semi-hardened materials. The inside diameter measures 1-3/8" （3.5 cm） allowing small food particles to easily pass through the valve opening during sample collection. The clear tubing is easy to see through and the 1 ft. （0.31 m） red markers show the amount of grease accumulated in the tank. To use, slowly lower the sampler to the bottom of the tank – the valve opens and the liquid fills the tube. Lift the sampler up which closes the valve, holding the sample inside, showing the grease level. To empty, touch the plastic tip on a hard surface, and the liquid will flow out. The unit is made of two 4-ft. （1.22 m） sections that screw together.
