Dry heat sterilization uses hot air to raise the temperature of an item to above a validated temperature which eliminates, removes, kills or deactivates biological contaminants and other biological agents on the object. These biological contaminants may include fungi, bacteria, viruses, spore forms and prions. The dry heat sterilization cycle is dependent on time and temperature, meaning as the temperature is increased the amount of time to achieve sterilization is decreased. The Dry Heat Sterilization Process Dry heat sterilization relies on heat conduction and heat convection. During the process, hot air sterilizers are used to heat up objects for decontamination

Industrial ovens are used for processes that require the application of heat to a material. Some of these processes involve the heating of volatile or flammable solvents. For hazardous material processing, a safety oven, which includes class A ovens and explosion-proof ovens, is required to reduce the risk of a fire or explosion. These ovens are designed to address one of the three ignition sources in volatile applications: oxygen, heat, or fuel. Safety oven designs vary greatly in the technology used, complexity, initial cost, and ongoing operating and maintenance costs. Designs are also heavily dependent on industry standards in relation

There is nothing easy when it comes to drilling and extracting oil, especially down-the-hole (also known as down-hole or DTH) drilling. Down-hole drilling is favored for its efficiency to cut through hard rock while maintaining a straight line into the earth. Down-hole drilling is a multi-step process that involves strategic planning. Before any drilling can occur, first a geologist must find oil. The most common way to do this is to conduct a seismic survey by sending shock waves into the earth’s surface. If the readings are favorable to the possibility of an oil trap, the land must then be

Sterilization is essential in the lab animal science industry. Animal cages, tools, surfaces, and lab equipment require thorough sterilization to prevent the transfer of harmful microorganisms and pathogens which can have devastating consequences for the lab animals and the studies being performed. Animal science lab technicians have traditionally used steam autoclaves to clean and sterilize their tools and equipment, but a growing number are switching to dry heat sterilization methods. Autoclaves and dry heat sterilization are both used in the lab animal science industry to sterilize animal cages to keep lab animals healthy. There are a number of differences between

Throughout the years, contact lenses have continued to gain popularity as the product offerings have expanded to provide more comfort, flexibility in frequency, and affordability. The first contact lenses were made from blown glass which only allowed for a few hours of use. They were lacking in comfort and relative clarity. Since then, the materials, quality, and comfort of contact lenses have continually improved. In the not so distant future we will begin to see technological advances that are focused on adding more functionality within the contact lens.

University laboratories, research centers, and other facilities use a wide variety of equipment to meet their research needs. In the earliest days of scientific studies, researchers used whatever equipment most closely fit their needs and finances – most did not consider the effects the use of such equipment might have on the environment. To help students get the most out their academic experience, many university classes add lab time to their curriculum. The hands-on experience helps students grasp the information provided in the lectures and put what they learn into practice. Lab time is particularly beneficial for science and pre-med

Lab equipment comes in a variety of different shapes and sizes, which requires heat sterilization to be used instead of typical chemical sterilization. Dry heat sterilization is a popular method for quickly and effectively sterilizing a wide range of products with many different applications. The importance of keeping lab equipment free of microorganisms, bacteria, and other contaminants is necessary, because it can skew important data collection results. In many cases, spot sterilization is not enough to ensure that the equipment is fully free of contaminants. Lab equipment and tools, especially in the pharmaceutical industry, need to be free of contaminants

Laboratory ovens are commony used in research and development (R&D) institutions, including universities. Many universities and R&D institutions use laboratory ovens in their most basic function – to sterilize lab equipment and glassware – but the ovens are also used for a wide range of applications. What are Lab Ovens Use For? Environmental laboratories, for example, may use them to determine the moisture content of specimens by weighing the specimens before and after drying. Often referred to as drying ovens or moisture extraction ovens, these lab ovens are an important tool for learning at universities. They offer a hands-on approach
