Herbal extractions are physical processes that separate the active compounds of a plant (such as resins, trichomes, or essential oils) through filtration.
In our market, they are carried out using extraction meshes of calibrated micron size, either in water/wet or dry, without solvents or chemical processes. In our market, they are carried out using extraction meshes of calibrated micron size, either in water/wet or dry, without solvents or chemical processes.

Water/wet extractions: extractions are carried out by agitation in water between 0.5 and 3.5º, followed by progressive filtration with meshes of different micrages.
The plant material is subjected to controlled movement (manual or mechanical) and then filtered by gravity or pressure.
The result is collected in each mesh according to its pore size.

Dry extractions: extractions are carried out by agitation or vibration with dry plant material, followed by progressive filtering with meshes of different micron sizes.
The material is subjected to controlled movement (manual or mechanical) and then filtered by gravity or pressure.
The result is collected in each mesh according to its pore size.

The screens are placed in descending order of mesh size within the filtration system (manual or mechanical).
• The top screen retains large particles.
• The intermediate screens separate specific fractions.
• The finest meshes capture the most delicate compounds.
Each medicalNetS kit includes 100% filtering meshes, numbered and labelled for ease of use.

You can watch the following informative video for more details: How to use the meshes?

With our kits you can perform:
• Standard extraction: for dry or cured material.
• Fresh Frozen extraction: for fresh and freshly frozen material (without prior drying).
• Outdoor Extraction: for field work without access to freezing and with more irregular plant material.
Each type has manual and mechanical variants, and different combinations depending on the intended use.

These are extractions made with fresh, freshly frozen plant material, without drying.
Their main function is to better preserve the aromatic profiles and integrity of the trichomes and prevent the evaporation of some of the aromatic compounds, resulting in a product with a higher terpene profile in terms of both quality and quantity.
They require specific meshes and kits designed to work in different circumstances.

Each kit is designed for a specific purpose:
Standar Kits  for general use, adaptable to all needs. 
Fresh Frozen Kits  for freshly harvested and frozen plant material.
Outdoor Kits  for outdoor plants with less uniform plant material.

Depends on the level of extraction and screening desired:
   • Basic: 3-5 meshes (e.g. 220, 120, 25 µm.)
   • Professional: 5-/ meshes (e.g. 220, 160, 120, 73, 25 µm.)
   • Connaisseur: up to 10 meshes (e.g. 220, 190, 160, 140, 120, 90, 73, 45, 25 µm.)
