70 Years of American Made Autoclaves

Written by: Arthur Trapotsis

Seventy years ago William A. Barnstead acquired Consolidated Machine Corporation with a focus on producing rolling door autoclaves and water stills for the U.S. Department of Defense. Barnstead, an entrepreneur and rugged individualist, worked diligently to create for his company a strong and lasting reputation as an innovator in the sterilizer and water still industry. […]

Biosafety Levels 1, 2, 3 & 4: What’s the Difference?

Written by: Arthur Trapotsis

Updated 11/3/22:  Information about the biosafety level requirements for handling SAR-CoV-2 (COVID-19 coronavirus) can be found here. Safety is of the utmost importance in any laboratory setting, especially when working with autoclaving equipment. In order to ensure the safety of lab personnel, the environment and surrounding communities, the Centers for Disease Control and Prevention (CDC) […]

Laboratory Autoclave Steam Sterilization Cycles, Part 10

Laboratory Autoclave Steam Sterilization Cycles, Part 10: Immediate-Use (Flash) Sterilization Cycle

Written by: Arthur Trapotsis

There has been much debate around the antiquated term “flash” sterilization. The Association for Advancement of Medical Instrumentation (AAMI), the Joint Commission (JC), and the Food and Drug Administration (FDA) have all made a concerted effort to clarify the use of flash sterilization, which is now known as immediate-use steam sterilization (IUSS). The particular cycle is not intended for routine sterilization but rather when specific instruments are needed for an emergency procedure.

Compared to traditional gravity or vacuum cycles, which are performed at 250°F (121°C), immediate-use cycles are performed at elevated temperatures of 270°F–275°F (132°C–135°C). As a result, immediate-use sterilization cycles are often shorter than gravity or vacuum cycles, which is where the “flash” in flash sterilization comes from.

Laboratory Autoclave Steam Sterilization Cycles, Part 9: Air Over-Pressure Cycle

Written by: Arthur Trapotsis

In the ninth installment of our Steam Sterilization Cycles Series, we explore Air Over–Pressure, another cycle used to sterilize a specific type of liquid load. An Air Over-Pressure Cycle is used to sterilize small liquid loads that are extremely sensitive to evaporation or boil-over in laboratory autoclaves. Typical applications for this cycle include pre-filled pipet tips, small pre-filled vials, loosely capped flasks, foil sealed glassware, or any partially vented containers where even small amounts of evaporation are not acceptable.

Bowie-Dick & Vacuum Leak Tests: Autoclave Sterilization Cycles

Written by: Arthur Trapotsis

The entire purpose of a laboratory or medical autoclave is to, quite simply, sterilize; however, without the proper conditions for sterility, an autoclave may fall short of its mission. Validation is an essential quality assurance measure designed to ensure that your autoclave operates exactly as intended. There are a number of different ways to validate […]

Why Our New Laboratory Sterilizer Took 4 Years to Develop: A Letter From The CEO

Why Our New Laboratory Sterilizer Took 4 Years to Develop

Written by: Arthur Trapotsis

I’ve been CEO of Consolidated Sterilizer Systems for 6 years now and one thing I’ve learned along the way is to appreciate and embrace customer feedback. Early on in my career I kept hearing conflicting information about the design of our sterilizer doors. I would hear comments like; “Why don’t you offer a vertical sliding door sterilizer?” and “We love your radial-arm, hinged door.” Believe it or not, these seemingly different sets of customers were saying the same thing—that they both had poor experiences with the existing vertical door laboratory sterilizers on the market. Despite this information, we waited. The truth was we knew that vertical door sterilizers were prone to more errors and maintenance than the traditional, “radial arm, hinged” door and we wanted nothing to do with it. Read more →

Steam Sterilization Cycles, Part 7: Product Lifecycle Testing in an Autoclave

Steam Sterilization Cycles, Part 7: Product Lifecycle Testing in an Autoclave

Written by: Arthur Trapotsis

In our 7th installment of the Advanced Cycles Series, we explore automated product lifecycle testing in an autoclave. Repeated exposure to an autoclave chamber’s extreme temperature and pressure conditions allows Quality Control Specialists to sharply accelerate product aging and evaluate the lifecycle of a product. Typically, this process requires that an individual (e.g. technician, scientist, engineer, etc) spend countless hours in front of an autoclave. What if you could program the autoclave to run multiple sterilization cycles (over multiple hours or days) with the press of a single button? Read more →
