AZLON
Frequently asked questions
Common questions about AZLON from 3G Electric.
What materials are AZLON carboys made from, and what are their chemical resistance properties?
AZLON carboys are manufactured from polypropylene (PP), a thermoplastic polymer known for its excellent chemical resistance. Polypropylene is resistant to many acids, bases, and organic solvents at room temperature, though it may be attacked by strong oxidizing agents and some hydrocarbons. The material has a low moisture absorption rate, making it suitable for storing aqueous solutions. It can withstand temperatures up to 135°C, allowing for autoclaving at standard sterilization cycles. However, prolonged exposure to UV light may cause degradation, so these carboys are best stored away from direct sunlight.
Are AZLON carboys autoclavable for sterilization?
Yes, AZLON polypropylene carboys are autoclavable. Polypropylene can withstand repeated autoclaving cycles at 121°C (250°F) at 15 psi for 15-20 minutes, which is the standard laboratory sterilization condition. However, the screw-on cap should be loosened during autoclaving to allow pressure equalization and prevent deformation. Over time, repeated autoclaving may cause the polypropylene to become brittle, so the carboys should be inspected regularly for cracks or warping.
What capacities are available for AZLON rectangular carboys?
AZLON rectangular carboys are available in capacities of 5 liters (1.32 gallons), 10 liters (2.64 gallons), and 20 liters (5.28 gallons). These sizes cover common laboratory and industrial storage needs. The 5-liter and 10-liter models feature molded handles for easy carrying, while the 20-liter model has a squat profile for stability. All models include a threaded screw-on cap. The dimensions vary by capacity: the 5-liter is 220 mm x 270 mm, the 10-liter is 280 mm x 420 mm, and the 20-liter is 350 mm x 360 mm.
Can AZLON carboys be used for storing food or beverages?
AZLON carboys are made from polypropylene, which is generally recognized as safe for food contact by regulatory bodies like the FDA. However, these carboys are not specifically marketed for food or beverage storage. They are designed for laboratory and industrial use, such as storing chemicals, reagents, or distilled water. If used for food or beverages, ensure the carboy has not been previously used for hazardous chemicals and is thoroughly cleaned. The colorless polypropylene allows for visual inspection of contents, but no food-grade certification is claimed by the brand.
What is the closure type on AZLON carboys, and is it leak-proof?
AZLON carboys come with a screw-on cap made from polypropylene. The cap provides a tight seal that is leak-proof under normal handling and storage conditions. The threaded design allows for secure closure, and the cap can be tightened by hand. For additional security, some users may apply PTFE tape to the threads, though this is not required. The cap is not vented, so pressure buildup from volatile liquids or temperature changes should be managed by loosening the cap periodically.
How should AZLON carboys be cleaned and maintained?
AZLON polypropylene carboys can be cleaned with mild detergents and warm water. For stubborn residues, isopropyl alcohol or dilute acids (e.g., 10% hydrochloric acid) can be used, but avoid strong oxidizing agents like concentrated nitric acid. The carboys are autoclavable for sterilization. After cleaning, rinse thoroughly with distilled water and air dry. Avoid abrasive scrubbers that could scratch the surface. Store carboys away from direct sunlight and heat sources to prevent material degradation.
