Homogenizers are used to break down samples—including food products, cosmetics, soil, plant matter, tissues, and more—before those samples are analyzed. The goal of homogenization is to produce a sample with the analytes of interest dispersed uniformly throughout. There are handheld and bench-mounted configurations available, along with a variety of probes to match various sample types.

6 Questions to Ask When Buying a Homogenizer:
- What type of samples and materials—and what volumes—are being processed?
- How much wattage is required to process samples?
- How many samples can be processed at once?
- How long does homogenization take?
- How much heat is generated? This is important to know if you have heat-sensitive samples.
- How noisy is the homogenizer?
Applications in Cannabis Testing
Homogenizers play an important role in the sample prep stage of cannabis product testing. Because achieving the smallest particle size possible is the key to accurate test results, high pressure or ultrasonic homogenization are often the best choices, depending on the scale of testing.

When choosing probes for your homogenizer, consider the size and consistency of your samples. Samples of the smallest volumes and softest consistencies use the narrowest probes with flat bottoms, while larger and tougher samples will require medium-sized probes with saw-tooth blades. Large probes with open-slotted bottoms can be used for larger volumes and thicker samples in beakers and flasks.
