For those in the biopharmaceutical industry, handling the preparation of large volumes of solutions comes with its fair share of challenges. A seamless process is crucial to the quality of the end product, and that means ensuring homogeneous mixing and blending with zero contamination. A balance of sanitation and efficiency is key, especially when it comes to mass production—and the mixing and blending equipment you use plays a significant role in this process.

How to use the mixer, agitator or tank

The best part of using a carboy mixer, agitator or tank is this: it doesn’t require a lengthy manual to figure out. In fact, it’s as easy as 1, 2, 3: add your ingredients, turn the mixer on, and pump them out—and just like that, you’ve simplified your mixing process. We promise, there’s no catch!


Why you should use our carboy mixers for your mixing tank system

With the most extensive offering of carboy mixers and agitators for sanitary and biopharmaceutical purposes, we have myriad options to suit your manufacturing processes. Here are some of the features and services we offer that make our products exceptional in these industries.
