How to Choose a Desiccator Cabinet: 2026 Buying Guide
A desiccator cabinet keeps moisture- and dust-sensitive materials in a sealed, low-humidity environment. Choosing the right one comes down to three decisions: size and compartments, clear or amber acrylic, and how you'll control humidity. This guide walks through each and maps it to the Yamato Scientific 860 series — clear and amber acrylic cabinets made in the USA.
1. What size — and how many cubicles?
Size the cabinet to your largest item plus headroom, then decide whether you need separated storage:
- One cubicle — a single sealed compartment. Available 12"×12"×6", 12"×12"×12", and 12"×12"×24" (PLA-8605, 860, 8615).
- Two cubicles — independent compartments so different materials (or different users) stay separated, each with its own door. Available 12"×12"×24", 18"×18"×18", and 24"×18"×24" (PLA-861, 862, 863).
Tip: the two 12"×12"×24" options (PLA-8615 single vs PLA-861 dual) have the same footprint — choose dual cubicles if you need to isolate samples.
2. Clear or amber acrylic?
- Clear (CGNS) — maximum visibility for general storage of specimens, electronics, and hygroscopic materials.
- Amber (CGANS) — UV-filtering acrylic that protects light-sensitive specimens, reagents, and standards from photodegradation while still letting you see inside.
3. How will you control humidity?
The sealed ¼"-thick acrylic cabinet holds a low-humidity environment; you maintain it with a desiccant (such as silica gel or molecular sieve) placed inside, or by purging with dry inert gas. The transparent design lets you read a humidity indicator and inspect contents without breaking the seal. For light-sensitive work, pair the humidity control with an amber cabinet.
Why acrylic — and why made in the USA
¼"-thick acrylic is rigid, chemically resistant, and optically clear, giving a durable cabinet that won't cloud or distort the view of your contents. Every 860-series cabinet is manufactured in the USA, in stock and ready to ship.

Frequently Asked Questions
What is a desiccator cabinet used for?
It stores moisture- and dust-sensitive materials — research specimens, hygroscopic chemicals, calibration standards, and sensitive electronic components — in a sealed, low-humidity environment that prevents moisture damage and contamination.
Should I choose a clear or amber desiccator?
Choose clear for general storage with maximum visibility. Choose amber when contents are light-sensitive — the UV-filtering acrylic protects reagents, specimens, and standards from photodegradation while still letting you see inside.
What is the difference between a one- and two-cubicle desiccator?
A one-cubicle cabinet is a single sealed compartment; a two-cubicle cabinet has two independent compartments, each with its own door, so you can store and access different materials separately.
How do I keep the cabinet dry?
Place a desiccant such as silica gel or a molecular sieve inside, or purge with dry inert gas. The transparent acrylic lets you monitor a humidity indicator and inspect contents without opening the door and breaking the seal.
