Cannabis & Botanicals

Protect Your Cannabis or Botanical Production Process from Contamination

Botanical and cannabis production manufacturing processes are highly regulated and require standardized laboratory practices to ensure high quality products. Botanicals which contain powerful natural antioxidants that scavenge free-radicals to protect the human body inside and out are said to do anything from improve digestion to minimize the risk of cancer. Care is taken during the manufacturing process to minimize personnel exposure to chemicals and botanical substances, while also protecting botanical and cannabis products from contamination.

Botanicals are substances obtained from a plant – in part or in whole – and used as additives in products within a large number of industries. Cannabis typically refers to the entire plant, stems, leaves, and seeds, as well as the botanical compound while the term marijuana historically excludes the plant stalks, oils, and other products used by the hemp industry.

Air Science manufactures laboratory products that are designed to protect operators, the environment, and the product during botanical and cannabis processing. Purair® Basic and Advanced Ductless fume hoods, the Purair BIO, and the Purair FLEX are all products that can assist botanical and cannabis manufacturers in certain steps of their process.

Ductless Fume Hoods: Air Filtration

Certain sterilization techniques used in the botanicals industry rely on various chemicals to sterilize, leach, and extract active ingredients from the plants. These processes can lead to personnel exposures that exceed defined safe exposure limits. Proper personal protective equipment, as well as purpose-designed safety barriers and equipment are necessary to ensure the safety of all personnel involved in the handling of raw materials and finished botanical products.

Ductless fume hoods airflow

Ductless fume hoods are simple to install and can be purchased for almost any application. Ductless fume hoods are designed to capture harmful vapors on the work surface to protect operators from exposure. The contaminated air is then thoroughly filtered and clean air is released back into the laboratory or manufacturing environment.

Purair Basic and Advanced series ductless fume hoods are designed to protect the user and the environment from hazardous vapors that are generated on the work surface, such as those created by the cannabis or botanicals extraction process. Purair fume hoods use the Air Science Multiplex™ Filtration System, which filters out a wide range of chemical families with multistage, replaceable carbon filters.

  • 24 Basic models and 42 Advanced models are available to fit any application.
  • Standard and shallow depth models, 120V or 230V available.
  • Air handling system delivers 100 fpm face velocity to ensure vapors stay inside the hood.
  • Filter clamping design eliminates bypass leakage outside the cabinet.
  • Low airflow alarms warn of insufficient face velocity.
  • Metal or polypropylene construction.
  • Backup filters are available to increase the range of applications.

Biological Safety Cabinets: Particle Control

Some botanical production procedures do not cause vapors, but do release particles of dust, plant biomass, and spores that may be detrimental to operators and the surrounding environment.

The Purair BIO Biological Safety Cabinet is a Class II Type A2 biosafety cabinet (BSC). The Purair BIO minimizes and contains Biosafety Level 1-3 agents, maintaining negative pressure inside the cabinet during operation to prevent contaminants from escaping the work area. HEPA filtration scours 70% of incoming room air to protect products, while the remaining 30% of exhausted air is filtered by a second HEPA filter.

  • Available in 4′, 5′, and 6′ models with 120V or 230V available.
  • No venting to the outside; easy to install and move.
  • Saves construction costs as no additional facility ductwork or HVAC improvements are needed.
  • Uses AstroCel® HEPA filters to physically capture particles larger than 0.3 microns with >99.995% typical efficiency.

Isolation Chambers: Product and Process Isolation

Some botanicals manufacturing applications do not require additional airflow but do necessitate separation from the product or process for various reasons. Isolation chambers allow complete containment of the process and product within the chamber, effectively separating them from the operator and outside contaminants.

The Air Science Purair FLEX is a low cost, easily moved isolation chamber that can be used almost anywhere. The Purair FLEX is constructed of ArmorFlex® film which offers complete visual clarity and excellent solvent resistance across a range of chemicals.

  • Internal volume of 3 cu.ft. (85 L) with a large work area and a 12.5″ (317 mm) gas tight zippered access with a 6″ (152 mm) diameter opening.
  • ArmorFlex film complies with FDA 21 CFR and 2002/72/EC standards for minimal outgassing, solvent and biological reactivity and static resistance.
  • Constructed with FDA approved pharmaceutical grade LLDPE1 anti-static and ESD2 safe and meets European ATEX Directive.
  • A nitrogen gas barb is a standard feature to permit creation of an oxygen-free workspace.
