Genevac has posted a YouTube™ video of a demo at California Gold Extractions (San Diego, USA) which compares use of a rotary evaporator and the Genevac Rocket Synergy evaporator, for the batch concentration of 2 liters of winterized cannabis extract in ethanol.

Cannabis oil extract has been used medicinally for generations to help treat a variety of conditions, and its popularity has increased considerably in recent years. Of the various extraction methods used, ethanol extraction is increasingly becoming the method of choice because of its ability to economically and effectively produce an extract with a high terpene content that is safe for consumption.

In the video interview, Jim Bilotta of California Gold describes the protocols required to batch concentrate winterized cannabis extract in ethanol using both a rotary evaporator and a Genevac Rocket Synergy evaporator. Mr. Bilotta confirms the considerable walkaway automation benefits of the Rocket Synergy evaporator both in terms of freeing staff to do other tasks and reproducibly producing a top quality cannabis oil extract.

Genevac Rocket and Rocket 4D Synergy evaporators set a new benchmark in evaporation versatility. Fitted with a stainless steel evaporation vessel either system can dry or concentrate batch volumes of up to 5L with no user intervention or attention. An auto-feed system on the Rocket 4D synergy extends capacity, enabling unattended automated processing of many tens of liters of product. For further operational versatility the bowl rotor may be quickly removed and replaced with a six position flask rotor to accommodate the full range of Rocket Sample handling solutions such as flasks, tubes and SampleGenie.

Five times faster than other 'intelligent' evaporators, the Rocket Synergy evaporator is capable of replacing several rotary evaporators, from benchtop to 50- liters capacity, saving valuable bench space and improving your productivity.

Rocket Synergy Evaporator

Genevac

Rocket Evaporators use patented vacuum technology to evaporate solutions to dryness, or a concentrate, rapidly and safely. The latest Synergy series offers integrated, flexible solutions for processing a wide range of sample volumes. Interchangeable rotors will accommodate tubes, flasks and batch volumes of up to 100L. Rocket Synergy is designed primarily to quickly process larger volumes of solvent in parallel and without supervision. The Rocket Synergy Evaporator will accommodate six flasks, each containing up to 450ml of solvent, as well a variety of innovative Genevac sample holders such as the SampleGenie. The removable rotor may also be replaced with a 5L 316 stainless steel vessel for batch processing. Now you don't need to choose between flask or batch/feed evaporation. The Rocket and Rocket 4D Synergy evaporators will accommodate your process, whatever the volume. Each is capable of replacing several rotary evaporators and saving valuable bench space.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Sample ManagementSample management systems include sample storage devices such as freezers and plate storers, sample environment enclosures and sample organization, retrieval and sorter systems. Useful system features include high-throughput, automation, robotic arms, automated liquid handling and associated database systems. Accessories in sample management include barcode scanners, heat sealers and tubes.Medicinal ChemistryMedicinal chemistry is a broad discipline encompassing the design, identification, synthesis and development of chemicals in drug discovery. It includes a number of techniques covering structural biology, synthetic chemistry and molecular biology. Technologies used in medicinal chemistry include ADME, lab-on-a-chip, high content screening and assay assembly.Biopharmaceutical AdvancesBiopharmaceutical advances follow the development of pharmaceuticals derived from biotechnology, also known as biotechnology medicines. Biopharmaceuticals may be produced from cell lines, plants, or microbial cells. Important considerations of biopharmaceutical use include application, cost, production process and purification.Robotic InstrumentsRobotic instruments can be used for high-throughput automation of many lab processes. Such processes use instruments for assays like cell based assays and ELISA, for sample preparation like shakers, centrifuges and incubators, and for analysis such as sequencing and western blot analyzers. Useful features of robotic instruments include speed, reproducibility, barcode readers, software and automation.Robotic WorkstationsRobotic workstations are automated platforms enabling the user to perform high-throughput, multi-application processes, from sample preparation tasks such as PCR set-up, DNA purification and NGS library preparation, to integrated sample prep and analysis workstations. Automation makes processes consistent, fast, precise and fully walk-away.

The robotic, liquid handling arms can dispense from single channel to 3456 multichannel as well as operate nanoliter dispensing, enabling high throughput of samples. Find the best automated liquid handlers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Evaporators and Freeze DryersCentrifugal evaporation is used for solvent removal from a sample. This is a useful technique for sample concentration or sample drying. Many centrifugal evaporators are modular with a central vacuum pump for generating low pressure. Useful features of evaporators or vacuum ovens include minimal solvent bumping, solvent resistance, computer control, temperature regulation and benchtop design.Compound AnalysisCompound analysis is used to discover specific compounds that could be promising candidates for pharmaceutical use. This potential is identified when compounds have the desired effect, such as interaction with a target protein, during high throughput screening.Drug DeliveryDrug Delivery refers to dosage form, route of administration, formulations, technologies, and systems for transporting a pharmaceutical compound in the body as needed to safely achieve its desired therapeutic effect. Drug delivery is often approached via the biopharmaceutical or small molecule drug's formulation, but it may also involve medical devices or drug-device combination products. Considerations include instrumentation, software and services. RegulatoryPharmaceutical regulations impact on all areas of drug development, manufacture and control and supply. Services are provided from the early stages of drug development and clinical trials through to dossier submission, approval and marketing. Regulatory also includes submission of analytical studies from the pharmaceutical product and safety. Scale-upScale-Up is generally defined as the process of transferring the results of the discovery phases of the drug discovery process, obtained on a laboratory scale, to the pilot plant and finally to production scale. Scale-Up uses reactors and pump systems as well as reagents, standards and buffers. Often Scale-Up is provided as a service by Contract Manufacturing Organizations (CMOs). Bioprocessing / FermentationBioprocessing is the use of biological materials to perform commercial, scientific or medical research processes. Biological materials used include cells, enzymes and organisms. Usually bioprocessing requires a batch or continuous bioreactor such as a fermentor or cell culture system. The advantages of using a reactor include high productivity, easy configuration, adjustable values and automation.Drugs of AbuseA drug of abuse is a drug that has been taken for non-medical purposes. Such drugs can have mind-altering effects, with some causing dependence and addiction.Ethanol
