Bubble Hash Bag Micron Guide
A 73 micron bubble hash bag has a nominal opening of 0.073 mm. In an ice water hash stack, it is typically used as a primary quality collection bag.

The micron number defines the nominal mesh opening in the filter panel. A 73 micron bag retains particles larger than the opening while allowing water and smaller particles to pass into the next bag.
When a 73 micron bubble hash bag is used in ice water extraction, its process role is direct: Retains a high-value resin fraction that is often reviewed closely for melt quality and visible cleanliness.
These formulas describe the unit conversions used for bag opening references.
mm from micron
mm = micron / 1000
73 / 1000 = 0.073 mm
micron from mm
micron = mm x 1000
0.073 mm x 1000 = 73 microns
inch conversion
inch = micron / 25400
73 / 25400 = 0.00287 in
Each note is assembled from the selected micron size and bag role so the page stays aligned with the data table above.
When a 73 micron bag is used for ice water hash extraction, the nominal opening is 0.073 mm. This supports the following collection role: Retains a high-value resin fraction that is often reviewed closely for melt quality and visible cleanliness.
In a typical bubble hash bag set, the 73 micron bag functions as a primary quality collection bag. This placement helps define which resin fraction is collected at this stage.
For hash rosin preparation, a 73 micron bag is selected when the operator wants premium bubble hash, high-quality resin heads, hash rosin preparation. Final pressing quality still depends on wash handling, drying, and contaminant control.
Buyers comparing 73 micron bubble hash bags should confirm bag diameter, vessel fit, mesh fabric, stitching, labeling, and whether the set includes matching pressing screens or storage bags.
45 micron is the next tighter bag in this reference set. 90 micron is the next more open bag in this reference set. Operators normally choose the bag stack by target resin head size, desired grade separation, drainage speed, and how much plant material is expected in the wash.
Micron values are presented as nominal mesh openings for bubble hash bag selection. Actual flow rate and collection behavior vary with mesh fabric, seam construction, biomass preparation, agitation, temperature, and operator technique.
Check gallon size, vessel fit, mesh fabric, seam reinforcement, labeling, and included accessories before purchase approval.
