This whitepaper outlines how new & existing processing labs can begin successfully making live rosin SKUs and how to use quality fresh frozen material to do so. 

By utilizing the Crystalline device coupled with a Tornado Raman spectrometer, it is possible to monitor and track polymorphism and morphology at low working volumes.

Automating your solid-state screening process enables you to perform the crystallization experiments with just a small amount of effort. Both CrystalBreeder and Crystal16 are the perfect tools for determining solubility in an easy and efficient manner. The solubility of your compound in organic solvents or water plays an important role when designing a crystallization screen. Knowing the solubility will allow you to select suitable solvents for the different crystallization methods.

The equipment used to achieve deep, stable vacuum, and separate fractions at the lowest possible temperature is critical to the process. Learn how using precise vacuum control allows for more efficient separation of plant oils and terpenes.

Finding the right combination of temperature and pressure allows the drying or evaporation process in a purge oven to be efficient. Learn how the vacuum pump used with a purge oven can maximize solvent recovery.

Filtering winterized extract requires strong vacuum in the right range to avoid product loss. VACUUBRAND’s application note addresses the essentials of flow and vacuum depth.

Running a Rotavap efficiently, and completing the evaporation at the fastest possible speed, is a matter of balancing the rate of evaporation with rate of condensation. Vacuum pump selection is critical to the efficiency.

The Crystal16 is a powerful system used for diverse solid state screening including co-crystal formation. Using 16 parallel reactors, you can test a wide diversity of crystallization conditions.
