【求助】USP正文的含量测定中用到high-speed blender是个什么样的装置？在哪能买到

USP正文Valproic Acid Capsules的含量测定中用到a high-speed blender，用它把胶囊打碎后测定含量。不知道这是个什么样的装置，在哪里能买到？
原文如下：Assay preparation— Transfer not fewer than 20 Capsules to a blender jar or other container, add about 150 mL of methylene chloride, and cool in a solid carbon dioxide-acetone mixture until the contents have solidified. If necessary, transfer the mixture of Capsules and methylene chloride to a blender jar, and blend with a high-speed blender until all the solids are reduced to fine particles. Transfer the mixture to a 500-mL volumetric flask, add n-heptane to volume, mix, and allow solids to settle. Transfer an accurately measured volume of this solution, equivalent to 250 mg of valproic acid, to a 100-mL volumetric flask, dilute with n-heptane to volume, and mix. Transfer 5.0 mL to a container equipped with a closure. Add 2.0 mL of Internal standard solution, close the container, and mix.
