Environmental Products & Reviews

Dedicated to providing the most comprehensive offering of reference materials for cannabis and hemp testing

We offer ISO-accredited microbiological certified reference materials. Validated and traceable cultures are no more than two passages from the primary reference culture ensuring genetic traceability to the primary cell line. Each lyophilized culture is preserved in our proprietary Microgel-Flash™ quick dissolve matrix. Pellets dissolve instantly once hydrated. Manufactured and tested under ISO 17034 and 17025 accreditations.

PFAS testing can be highly challenging which is why we make it easier with our convenient portfolio of PFAS reference materials. Advance environmental and health safety with standards you can trust.

The World’s First Microplastics Reference Materials. Our scientists have focused on these emerging global threats, and are excited to share Chiron MicroPrefs®, the first commercial microplastic reference material portfolio is designed to detect the six most abundant plastics in the environment and is available in a novel, easy-to-use tablet formulation.

We proudly provide the Industry with quality, accuracy, ease of use, and an extensive offering for all your testing needs! Spex®, NSI, and Chiron offers ISO 17034 Certified Reference Materials (CRMs) for all of the common contaminants such as pesticide residues, residual solvents, and heavy metals, as well as qualitative analysis CRMs.

The MD 610 multi-parameter photometer is a versatile water testing device designed for use in the lab, plant, or directly in the field. Pre-programmed with over 120 water testing parameters, it offers a wide range of applications across various industries.

Stunner AF adds fluorescence detection to plate-based, high-throughput rotating angle dynamic light scattering (DLS) and UV/Vis absorbance measurements from 2 µL on up to 96 samples. Combine all three technologies to measure LNP size, encapsulation efficiency (EE%), and particle concentration data in one experiment. Pivot and pair up UV/Vis and DLS to quantify and size proteins, ADCs, peptides – just like Stunner.
