Herbarium Cabinets: What They Are and Why Your Collection Needs Them

Written by Stuffey | Jan 7, 2020 4:10:08 PM

Pressed between pages or carefully arranged on archival paper, botanical specimens may look fragile. But they're the backbone of critical research, from climate studies to agricultural breakthroughs. And behind those pressed ferns, flowering plants, and fungi is a rock-solid herbarium cabinet keeping it all safe. 

Unlike standard storage furniture, herbarium cabinets are purpose-built for long-term plant preservation. They offer protection from light, pests, humidity, and even time itself, all while keeping collections organized and accessible for researchers, students, and staff. 

It doesn't matter whether you're working in a university herbarium, a museum, or a research institution. The right cabinet setup makes all the difference. Let's break down what makes a herbarium cabinet essential, and how to choose one that fits your space, your workflow, and your collection. 

What Makes a Herbarium Cabinet Different?

You can't store century-old plant specimens in just any cabinet. At least, not if you want them to survive another century.

Herbarium cabinets are built with just that kind of long-term protection in mind. They're engineered to protect delicate, irreplaceable specimens from pests, humidity, UV exposure, and even cleaning chemicals.

Here's what makes them special: 

  • Air knows where to go. Herbarium cabinets are designed with extra space behind and in front of each compartment to allow for the safe circulation of air and fumigants, which is essential for long-term preservation.
  • Pests stay out. Period. Closed-cell elastomeric gaskets wrap the interior like a vault, keeping out dust, moisture, and insects. Combined with a three-point latching system, they create a secure, protective environment. 
  • Finishes that don't fight your collection. A non-off-gassing, powder-coated finish ensures the cabinet protects the plants inside without releasing harmful VOCs that could damage specimens over time.
  • They're made for the job. These cabinets come with rigid dividers, optional pull-out work surfaces, and layouts that actually make sense for botanical collections. 

Key Models and Features to Know

A cramped research space has different needs than a university herbarium or a full-blown museum collection. That's why herbarium cabinets come in different shapes, sizes, and setups. Each model is built to protect your specimens while working within your space and workflow. 

Let's take a look at three standouts:

Model 240

Think short, smart, and stackable.

This counter-height cabinet is great when you need extra storage and a bonus work surface. If you're not stacking them, they still double as a sturdy tabletop. This option is ideal for smaller spaces or paired configurations. 

Model 241

The classic choice.

Mid-sized and full-height, this cabinet includes 26 compartments and a handy pull-out work shelf. Great for institutions with traditional herbarium layouts and high specimen turnover. 

Model 242

Big capacity, narrow footprint.

Need more storage without blowing out your floorplan? The 242 is built for mobile compactor systems and tight aisles. It's the same internal storage as 241s, but slimmer and more budget-friendly. Bonus: it includes two pull-out work shelves for in-cabinet review. 

All three models come with: 

  • Reinforced steel construction
  • Closed-cell gaskets and three-point latching
  • Optional locking handles
  • Integrated levelers and WaterShield caps 

And each cabinet is designed to work with high-density mobile systems if you're looking to save space without sacrificing capacity.

How Herbarium Cabinets Fit Real Spaces

Plant collections don't stop growing just because you run out of room. 

Take the University of Tennessee's Herbarium. They were juggling more than 600,000 specimens, running out of floor space, and couldn't go vertical without breaking ADA compliance. Traditional shelving wasn't cutting it. As their Collections Manager put it, "We needed to fit the current collection but also be able to take on the influx of new specimens."

So they called Patterson Pope.

We worked with their team to design a high-density mobile system using herbarium cabinets that gave them more storage in the same footprint. They gained accessibility, preserved their existing organizational system, and left room for future growth. 

Whether you're storing rare mosses or fresh ferns from the field, herbarium cabinets can be paired with mobile systems, installed in tight corners, or configured for walk-up access. Add in features like pull-out work shelves and lockable handles, and you've got storage that, like with the University of Tennessee, can adapt as fast as your collection grows. 

Easy to Customize, Easier to Live With

Herbarium cabinets may look simple on the outside, but it's what's inside (and underneath, and on top) that makes them work so well for so many different environments. 

Here are some of the customization options that can help you choose the cabinet that's a perfect fit for your collection:

  • Pick a color that works with your space. Choose from a range of powder-coated finishes, all non-off-gassing and built ot last. Want your cabinets to match the wall, or maybe show a little school spirit? You've got options. 
  • Choose how you open and secure your cabinet. Whether you want a classic D-ring, a lever, or a recessed EMKA handle, you can pick the style and lock security level that works best for your team.
  • Adjust shelves and trays to fit what you're storing. Whether you're working with stacked folders or pressed samplers, the inside layout can flex with your needs. 
  • Stay steady, even when the floor isn't. Integrated levelers and WaterShield caps help protect your specimens from surprise leaks or uneven surfaces. 
  • Move it now, or move it later. Caster and forklift bases make it easy to reorganize, relocate, or grow into a new space without starting over. 

Protecting Plants (and the Work They Support)

Botanical specimens are more than pressed plants. They're historical records, scientific tools, and are often one-of-a-kind links to past and present ecosystems. They support research, teaching, and conversation, sometimes all at once. And keeping them safe for the long haul starts with the right storage. 

A good herbarium cabinet should protect against pests, moisture, dust, and disorganization. At Patterson Pope, we've helped organizations of all types and sizes rethink their space, protect their collection, and plan for future growth. So if you're staring down an overgrown (no pun intended) space and you're thinking, "There has to be a better way?" Good news. There is.
