Sterilizers & Drying Ovens

TPS manufactures Gruenberg and Blue M ovens for medical device drying, pharmaceutical granulation drying, lab utensil sterilization, and more. Superior airflow and temperature capabilities ensure uniform moisture removal, while a range of models with HEPA filtration, NFPA 86 Class B or Class “A” with optional inert atmosphere features meet the toughest industry requirements and safety standards. Common products processed in a Gruenberg or Blue M dry heat sterilizers or drying oven includes glassware, metal instruments, granulation and medical devices.

Why Dry Heat?

Dry heat sterilization eliminates, removes, kills or deactivates all forms of life and other biological agents (such as fungi, bacteria, viruses, spore forms and prions) by raising the temperature of an item to above 320°F. Heated air or steam can be used in this process. Our lab sterilizers are ideal for laboratory and pharmaceutical applications.

Dry heat ovens have several advantages of steam autoclaves, including higher temperatures and the ability to sterilize materials that might be damaged to steam or are impenetrable to moist heat. It is the most effective sterilization method, with lower energy and cost. .
