5 GALLON VACUUM CHAMBER: The spacious interior enables the production of purer, bubble-free crafts and experiments. The corrosion-resistant glass lid and stainless steel chamber are well-suited for stabilizing wood, handling volatile or corrosive materials, as well as for degassing silicone, resin, polyurethane, and vacuum extraction work. 24-HOUR AIRTIGHT SEAL: The glass lid features a sealing gasket and silicone seal cover, and the valve has been upgraded with threaded connections. Rubber gaskets are placed at the vacuum gauge connection points, providing excellent airtightness. The system can achieve a vacuum level of up to -29inHg. Through testing, it exhibits a leak rate of approximately 5% over 12 hours. HIGH-PRESSURE RESISTANT STRUCTURE: Made from high-quality 304 stainless steel, it can withstand high vacuum pressures without deformation. It also has corrosion resistance, ensuring it remains durable even if liquids splash inside the chamber during degassing.
