Determination of Mass and Moisture Content

If your lab is specialized in testing the potency of cannabis products you need to perform physical analyses to understand the cannabinoid and terpene content. For instance, you need to test the mass and moisture content of your samples. Performing measurements in a time-and cost efficient manner, while delivering accurate results, in compliance with strict regulations at the same time, sometimes seems to be a challenging balancing act. Speed up your moisture determination process with our fully automatic Moisture Analyzer MA 160, which cuts down your measurement times from hours to only minutes. And find firm support with our lab balances, which ensure accurate and reliable weight determination and compliant results. Our software supports your data integrity through enhanced security settings.

The MA 160 moisture analyzer is designed for quick and reliable moisture determination of materials containing a total moisture in between 1% and 99%. Its high speed measurements do not only make the MA 160 a perfect solution for quality control, but additionally enable quick at-line measurements during sample preparation.

Water for HPLC and Sample Prep

When analyzing cannabis and CBD products for purity, ultrapure water is the basis for safe and economical analytics, reducing interference and ensuring accurate measurements of cannabinoids and terpenes. The use of high-quality, ultrapure water is important for all daily standard applications in analytic labs, such as preparing stock solutions, buffers, or to dilute samples, but is especially important when performing chromatographic analyzes, such as HPLC, GC-MS or IC.

Water is used heavily for rinsing and dilution of samples to be tested. Furthermore, it is used for the preparation of certified reference materials within the calibration and testing of the instrumentation (GS-MS, HPLC) to evaluate the samples for contamination in the Cannabis testing process.

Our Arium® laboratory-grade water purification systems will inspire you with their application-oriented operating designs. The Arium systems enable you to perform your workflows faster and more reliably, make your daily lab work easier and ensure long-term economical operation. They can be perfectly integrated into your laboratory environment and easily adapted to your requirements, so they provide ultimate flexibility.

The Arium® Pro ultrapure water systems meet, and exceed, ASTM Type 1 water quality at an unmatched cost of ownership for any application. Available in a choice of five modular-design systems, this range offers the widest selection of features and options for customized configuration. The glass display with touch-activated functions, along with intuitive menu navigation, ensures error-free operation, even while you are wearing gloves.

Pipettes and Bottle Top Dispenser

A reliable and precise pipette is the indispensable right hand of each lab assistant and is therefore a must in every laboratory. Using advanced tips with your high-quality pipettes ensures the pipettes will last for a lifetime. Getting accurate cannabinoid and terpene content measurements are critical when analyzing cannabis and CBD products. Tips featuring low-binding technology plastics and manufactured without any leachables that may interfere with chemical analysis are critical for obtaining these accurate measurements. And if your testing procedure requires you to repeatedly portion out exact volumes of liquids involved, our bottle-top dispensers will give you a steady hand to ensure accurate and consistent results.

Superb comfort and incontestable reliability. That’s how  Tacta® makes pipetting effortless and safe while producing accurate and consistent results time after time.

The Tacta® pipette is chemically very durable and it offers you the possibility to use Safe-Cone filters, which protect the pipette from any solvent fumes that may occur while preparing Cannabis products for chemical analysis. Furthermore, with it’s easy-to-clean design Tacta® facilitates thorough decontamination of its pipette parts before microbiological testing.

HPLC Sample Prep | Preparation of standards

You must prepare a standard series with defined concentrations, if your cannabis testing lab is performing quantitative HPLC, GC-MS or ICP-MS to analyze cannabis, CBD edibles, and other CBD products. Without standards, you cannot know the potency of the active ingredients, such as THC, other cannabinoids, and terpenes, and cannot discern active ingredients from contaminants, such as pesticides, heavy metals or residual solvents and processing chemical. Certified reference material (CRM), however, constitutes a substantial expense, in particular for high-throughput testing labs. Producing your own high-quality reference materials (RM) for your analytical testing lab offers a cost-effective alternative, but must be performed with the highest precision to meet the strict legal requirements of cannabis testing regulations and ensure consumer safety. The Sartorius Cubis® MSA Dosing System provides a smart combination of innovative products to support you in precisely weighing for your analyses, and exactly defining and dosing the accurate volumes of solvents to produce high-quality, compliant RMs for your quantitative cannabis analysis.

The Cubis® MSA Dosing System simplifies your workflows in the preparation of analytical standards for Cannabis testing. Right after you entered the desired concentration(s) of the component(s) and the volume of the standard solution, the Cubis® MSA Dosing System automatically calculates the required amount of sample to be weighed and the target weight is shown as a bar graph including tolerances. With this solution the preparation of standards will be easier for you than it has ever been before. In high throughput testing environments, where larger volumes of many different types of standards are required, the dosing system fits in perfectly as a cost-effective and fast alternative to purchasing pre-made standards.

  • The perfectly integrated system will ensure highly accurate weighing by the Cubis® MSA balance and precise dispensing of solvents using automatic dispensers or electronic or manual pipettes.
  • Its software application will control system components by the YAPP16 Dosing Q-App.
  • Through automatic preparation of standards it will maximize efficiency and minimize your processing time while still ensuring utmost accuracy and precision.
