Freeze Dryer Xiros Micro
The Xiros Micro freeze dryer by Holand Green Science is a small, powerful freeze dryer designed for use in households as well as in research facilities, laboratories, and commercial production of freeze-dried products. Despite its compact size, the Xiros Micro cryogenic dryer has a large product capacity with up to 9 shelves and a capacity of 8 kg of ice/24h and 4 kg of sublimation/24 hours.
? With the Xiros Micro, you save a lot of time and money. It also requires minimal space.
The Xiros Micro cryogenic dryer features intuitive operation with a digital touch display for precise adjustment of drying time and temperature.
Freeze Drying Made Easy
Not all freeze dryers are the same. As often is the case, the devil is in the details. Many manufacturers offer devices that may look good and be relatively inexpensive to purchase, but then it quickly becomes apparent that corners have been cut in many areas.
This manifests itself, for example, in very loud operating noises (which can be very exhausting and annoying since a cycle can last between 4 and 24 hours).
Or spare parts are very difficult to obtain.
Or the manufacturer does not respond to support inquiries.
I have had the opportunity to see several freeze dryers and then decided on the Xiros Micro. It is easy to use, manufactured to high quality standards, and can be optimally adapted to your needs.
Since the manufacturer, Holland Green Science, is based in the Netherlands, comprehensive and fast support is always possible.
The Xiros Micro can be loaded with up to 8 kg of material. The maximum load weight depends, of course, on the products being dried. Approximately 10L of material volume for freeze drying fits in the Xiros Micro.

The Effect of Vacuum on the Drying Rate of Samples in a Freeze Dryer
The use of vacuum freeze dryers like the Xiros Micro by Holand Green Science has gained increasing importance in laboratories in recent years. This is because this type of dryer allows for fast and efficient drying of samples, particularly compared to conventional hot air dryers. An important factor in the use of vacuum freeze dryers is the vacuum applied during the drying process.
How Does Vacuum Drying Work?
Vacuum drying is a process where vacuum is used to reduce the humidity surrounding a sample. This allows water to evaporate from the sample more quickly, shortening the drying time. In a vacuum freeze dryer, the vacuum is generated by removing air from the freeze dryer using a vacuum pump. This lowers the relative humidity inside the freeze dryer and increases the drying rate.
Advantages of Vacuum Drying
One of the main advantages of vacuum drying is the faster drying rate. By reducing the humidity using vacuum, water can evaporate from the sample more quickly. This shortens the drying time, which is particularly important when drying samples in large quantities or thermolabile samples.
Another advantage of vacuum drying is that the samples are not overheated, which often occurs when using hot air dryers. Since vacuum is used to reduce humidity, the sample is not directly heated. This allows thermolabile samples to be dried safely without damage.
Another advantage of vacuum freeze dryers is the ability to dry "hazardous" samples. Since vacuum is used to reduce humidity, there is no need to directly heat the sample. This allows hazardous samples, such as explosive substances, to be dried in a safe environment.
Conclusion on Freeze Dryers in the Laboratory
Vacuum freeze dryers are a powerful and efficient method for drying samples in laboratories. They enable faster drying rates compared to conventional hot air dryers and allow for the drying of thermolabile samples without damage. However, they are more expensive compared to conventional dryers.
