Frequently Asked Questions
What is the Holland Green Science Xiros Mikro?
It's a benchtop, tray based freeze dryer built for lab scale and small commercial batches. It runs a full freeze, vacuum and slow sublimation cycle rather than drying with heat, so the finished product keeps its structure and potency far better.
Does the Xiros Mikro come with a vacuum pump?
No. You need to add a separate oil free scroll vacuum pump rated to 3A max to pull the vacuum. It is not in the box, and the machine will not run without one. We stock the Holland Green Science Anemos Dry Scroll Vacuum Pump for it.
How many trays does the Xiros Mikro hold?
This listing is the standard 5-shelf configuration, which takes 5 stainless steel trays at 200 x 450mm each. The stack is modular, Holland Green Science also offer 3, 7 and 9 shelf configurations.
What is the maximum load capacity of the Xiros Mikro?
9.6kg at 80% moisture content on the standard 5-shelf stack. Capacity scales with tray surface area, from 0.27 sq m on 3 shelves up to 0.8 sq m on the 9-shelf configuration.
How noisy is the Xiros Mikro?
54dB(A) without the pump running. The pump itself will add to that, so where you site the unit and which pump you pair it with both affect how much noise you'll actually hear day to day.
Can I use the Xiros Mikro for dairy or brewing?
No. Holland Green Science say this machine is not intended for dairy or brewing applications. It's built for botanical material, pharmaceutical sample prep and nutraceutical work instead.
Description
This is a benchtop freeze dryer built for lab scale and small commercial batches, not a kitchen gadget. It's for growers, breeders and small producers who want to preserve plant material, seed stock, extracts or other samples properly rather than just drying them in an oven or a dehydrator. The Xiros Mikro from Dutch manufacturer Holland Green Science runs a full freeze drying cycle, freeze, vacuum, then slow sublimation, so the finished product keeps its structure, flavour and potency far better than anything heat dried.

In the Box
The Xiros Mikro freeze dryer itself, the standard 5-shelf heated stainless tray stack with 5 stainless steel trays, and the mains lead. No vacuum pump is included, so you'll need to add an oil free scroll pump separately. This ships as a big crate, but there is a small parts bag with tray clips and fittings inside that is easy to miss and bin along with the packaging, so check it over properly before anything goes to landfill.
How Freeze Drying Works on the Xiros Mikro
The Xiros Mikro runs programmable cycles of up to 16 steps, controlling temperature, vacuum and timing through each stage. Shelves are individually heated, so you can run a proper freeze, vacuum and slow sublimation cycle rather than just blasting everything with heat. It has both manual and automatic modes, run from a touchscreen interface, so you can set a cycle once a recipe is dialled in and leave it to run.
Who the Holland Green Science Xiros Mikro Is For
Labs, breeders preserving seed stock, and small producers working at pilot scale, anyone who wants botanical material, pharmaceutical samples or nutraceutical products preserved properly rather than dried with heat. Holland Green Science are upfront that this machine is not intended for dairy or brewing use, so if that is what you are after, this is not the right tool.
