How we test
We measure endotoxin with a kinetic chromogenic Limulus Amebocyte Lysate (LAL) assay on an Endosafe nexgen-PTS. Results are reported in EU/mL, with spike recovery to show the sample does not interfere with the test.
We can also measure pH on solutions and bacteriostatic water.
What we measure
