Not every laboratory has the same requirements and that's exactly why we offer two upright VAULT solutions.

The VAULT100 delivers the performance, efficiency, reliability, and storage capacity laboratories have come to expect from Stirling Ultracold. It's an excellent choice for labs looking for dependable ULT storage with a focus on value, efficiency, and everyday sample protection.
The VAULT100 PRO takes that foundation and adds advanced capabilities designed specifically for laboratories with more demanding GxP processes and operational requirements.

They're designed to give laboratories options based on their specific needs.
Whether you're protecting research samples in an academic lab, supporting critical work in biotech or pharmaceutical environments, or operating within a highly regulated GxP process, there's a VAULT solution designed to fit your application.

Different needs. Different capabilities. Same commitment to protecting what matters most.

Take a look at the comparison and see which VAULT is the right fit for your laboratory.

Laboratories are being asked to do more with the space, resources, and budgets they already have. That means today's ULT freezer needs to deliver more than ultra-low temperatures. It needs to deliver efficiency, reliability, sustainability, serviceability, and smart use of valuable floor space.

At Stirling Ultracold, we've approached ULT storage differently.

Our free-piston Stirling engine technology allows us to design refrigeration systems that are remarkably compact, helping our freezers provide high storage capacity without requiring the same amount of valuable laboratory floor space as larger traditional systems.

Why does that matter? Because laboratory space isn't free.

Every square foot occupied by equipment is space that can't be used for another instrument, workstation, storage area, or future expansion.

A more compact freezer can help laboratories:

✔ Maximize sample storage within a smaller footprint
✔ Make better use of limited laboratory space
✔ Preserve valuable floor space for other equipment and activities
✔ Increase storage capacity without simply adding more equipment
✔ Reduce the overall footprint of their cold-storage infrastructure

And efficiency doesn't stop at footprint. Today's laboratories also need equipment that can help reduce energy consumption, support sustainability goals, minimize downtime, and remain serviceable throughout its operating life.

That's why we don't believe a ULT freezer should be evaluated by temperature performance alone. The better question is: How much value can you get from the space, energy, and resources it requires?

At Stirling Ultracold, we're designing ULT storage with the realities of today's laboratories in mind.

The Best Time to Maintain Your ULT Freezer Is Before You Need a Repair.

Your ultra-low temperature freezer works around the clock, protecting samples that may represent years of research, valuable clinical material, or irreplaceable biological specimens.
So why wait until something goes wrong to think about maintenance?

Preventative maintenance is about being proactive, not reactive.
Over time, things like dust accumulation, door gasket wear, battery condition, fans, and temperature performance can all affect how efficiently and reliably your freezer operates.

Regular maintenance can help:
✔ Identify potential issues before they become major problems
✔ Keep your freezer operating efficiently
✔ Maintain temperature performance
✔ Extend equipment life
✔ Reduce unexpected downtime
✔ Help protect the samples inside
Maintenance isn't one-size-fits-all. Different laboratory environments and usage patterns can create different service needs.

That's where Stirling UltraCARE comes in.
From preventative maintenance and calibration to requalification and other service needs, our team helps laboratories stay ahead of potential problems and keep their critical equipment performing as it should.

A proactive approach helps give your team something much more valuable: Confidence that your freezer is ready to keep doing its job.

Your Freezer Has the Space. Are You Using All of It?
When it comes to ultra-low temperature storage, every inch of usable space matters. And it also helps your freezer run more efficiently.
A well-designed storage system isn't just about fitting more boxes into a freezer. It's about making the most of your available capacity while keeping samples organized, accessible, and easy to retrieve.
Stirling Ultracold storage racks are designed to help laboratories maximize the space inside their ULT freezers while creating an organized system for sample storage.
That means your team can spend less time searching for samples and more time focused on the work that matters.

With the right rack configuration, you can:

✔ Improve accessibility so you can find what you need without unnecessary door-open time
✔ Maximize storage capacity within your freezer footprint
✔ Keep samples organized for easier identification and retrieval
✔ Make better use of vertical space inside the cabinet
✔ Build a storage system around your laboratory's specific needs

When you think about sustainability in the laboratory, you might think about recycling, reducing waste, or improving building efficiency.

But what about the equipment that runs around the clock? Ultra-low temperature freezers operate 24/7, 365 days a year. That makes energy efficiency an important part of the long-term sustainability equation.

At Stirling Ultracold, we took a different approach to ULT refrigeration. Our free-piston Stirling engine technology is designed to deliver ultra-low temperatures while using significantly less energy than traditional compressor-based systems.

That can mean:
Reduced energy consumption
Less heat released into the laboratory
Lower demand on HVAC systems
Lower operating costs
A smaller environmental footprint

Sustainability shouldn't mean compromising on performance. Your samples still need reliable, consistent protection and your freezer still needs to perform when it matters most.

We had another great monthly meeting this week, bringing all of our employees together to celebrate our successes, discuss opportunities for improvement, and share ideas on how we can continue serving our customers and community even better.

We call it our “All-Hands Meeting.”
Why?

Because it truly means all hands. Not just managers. Not just sales. Everyone.
We believe every employee has a valuable perspective and should have a voice in what we do and how we continue to grow.

Each month, we also recognize an employee who has gone above and beyond in their work, for their coworkers, and for our customers and community.
This month, that recognition went to Tim!
Congratulations, Tim, and thank you for everything you do. We couldn’t do it without you!
