A test result starts with the work at the bench.

Greenleaf Labs technicians use pipettes to measure and transfer small amounts of liquid, then prepare samples in tubes and vials for analysis. Those steps help the team follow the testing method consistently from sample to sample.

Before testing can tell you what’s in a batch, the lab needs to know exactly how much sample it’s analyzing.

At Greenleaf Labs, weighing the flower is one of the first steps in preparing a sample for testing. That recorded weight becomes part of the method used to calculate and report results.

Here, a Greenleaf Labs technician works with an analytical balance and pipette to measure materials for testing. Each step follows a defined method so the final result can be traced back to how the sample was prepared.
