Types of Autoclaves: Choosing the Right Chamber

There are so many types of autoclaves — not just in terms of autoclave processes (dry heat, steam, etc.). There are also seemingly small differences—like size, orientation, and chamber type—that can have a big impact on your lab’s operations.  How do you determine which is right for your lab? This is a really interesting article … Continue reading “Types of Autoclaves: Choosing the Right Chamber”

Battling Fatbergs Here and Abroad

Our UK associates were delighted to see a pair of Priorclave research autoclaves featured in a recent episode of Blue Planet UK on BBC One: The noble task of those autoclaves?  Helping scientist breakdown and analyze a massive “fatberg” found clogging the sewers of Sidmouth (an otherwise lovely fishing village in South West England). Blue … Continue reading “Battling Fatbergs Here and Abroad”

Trends in Retort Processing: Goodbye Canned Food, Hello “Retort Pouches”

For hundreds of years retort processing (i.e., “canning”) has made it possible to prepare spaghetti sauce in minutes—instead of hours—eat tuna regardless of how many thousands of miles you live from an ocean, and have veggies year-round. In terms of the production workflow and equipment, food and beverage retort processing has changed very little since … Continue reading “Trends in Retort Processing: Goodbye Canned Food, Hello “Retort Pouches””

Your Biohazard Waste Autoclave Procedure: What Time and Temperature?

When we last discussed red-bag waste autoclave procedure, we talked about running “your standard waste cycle” (noting that these vary by lab). So how do you determine your lab’s “standard” biohazard waste cycle?  The general rule for autoclave sterilization taught at most colleges is “15 minutes at 121ºC kills everything.“  But that’s definitely too short … Continue reading “Your Biohazard Waste Autoclave Procedure: What Time and Temperature?”

Autoclave Procedure for Pipette Tips

The autoclave procedure for pipette tips is a little more involved than other red bag waste. Why? Because pipette tips are pokey: They like to poke through bags and into people.  Even if your pipette tips themselves aren’t contaminated, they are a super-duper good vector for dangerous pathogens.  They’re also great at making sure goop … Continue reading “Autoclave Procedure for Pipette Tips”

Red-Bag Waste Autoclave Procedure

It’s a dirty job, but someone’s gotta do it.  Following this three-step autoclave procedure will result in reliable sterilization of “red bag” waste.  (Assuming that you aren’t running a BSL3 facility or disposing of animal carcasses.) Red Bag Waste Autoclave Procedure First things first, the DON’Ts: DON’T toss loose tips and pipettes into your biohazard … Continue reading “Red-Bag Waste Autoclave Procedure”

Autoclaving Big Beakers and Flasks? Use the Vacuum Function!

If you’re regularly autoclaving large Erlenmeyer flasks, graduated cylinders, or beakers—and it’s not practical to run the entire load lying horizontally—a vacuum function is vital to your consistent success. Why Autoclaving Containers is a Hard Autoclaving any container is inherently challenging—even when that container is open.  Why?  Dense cold air tends to pool at the … Continue reading “Autoclaving Big Beakers and Flasks? Use the Vacuum Function!”

This No-Cost Lab Autoclave Procedure Tweak Significantly Improves Sterilization

We’ve spoken at length about the follies of foil, and regularly help customers kit out autoclaves precisely suited to their specific tasks.  But there is one thing that any lab can do at no cost— TODAY!—that will massively boost the effectiveness of their steam sterilizer: Autoclave large beakers, flasks, and cylinders on their sides—especially Erlenmeyer … Continue reading “This No-Cost Lab Autoclave Procedure Tweak Significantly Improves Sterilization”

Laboratory Autoclave Procedure Warning: Do You Account for “Thermal Inertia”?

Many labs don’t heat large liquid loads long enough to assure sterilization. The standard autoclave procedure is “hold a load at 121ºC for 20 minutes to assure sterilization.”  This is endorsed by everyone, from the United States Pharmacopeial Convention and Food & Drug Administration, to the Department of Health & Human Services and every university on … Continue reading “Laboratory Autoclave Procedure Warning: Do You Account for “Thermal Inertia”?”

Lab Autoclave Function Primer: Intro to Air Ballast Systems

In general, autoclaving sealed flasks is a very, very bad practice.  But that isn’t to say it’s impossible.  If you need to sterilize sealed containers, then you need to make sure you have a special autoclave function to do it safely: an “air ballast” system. What’s an “Air Ballast” Autoclave Function? All steam autoclaves use … Continue reading “Lab Autoclave Function Primer: Intro to Air Ballast Systems”
