Dry Oven *18L China @42000 —— 53L China DHG-9053

The specifications below compare the Ibex Sciences 18L Chinese Dry Oven against the larger 53L Chinese DHG-9053 / DHG-9053A Dry Oven. Both are standard, constant-temperature hot air convection ovens imported from China, widely supplied locally by Ibex Sciences and local scientific distributors. [1, 2, 3, 4, 5]

• Uniformity & Air Flow: The DHG-9053 features a built-in low-noise fan system (Forced Air Blast) that forces hot air circulation. This ensures uniform heat distribution. The smaller 18L model typically relies on natural gravity convection, which can result in minor temperature pockets depending on how tightly items are packed. [1, 2, 3]
• Chamber Layout: The 18L model comes with 1 removable shelf, making it optimal for basic tools, individual glass beakers, or small moisture testing samples. The 53L model comes with 2 adjustable stainless steel grid shelves, allowing you to dry multiple batches or larger laboratory glassware simultaneously. [1, 2, 3]
• Controller: Both utilize a digital PID microprocessor controller with dual displays showing both the target and the actual chamber temperatures. [1, 2]
