Maximize Purity and Yield with Dulytek Filtration
Trusted by solventless enthusiasts for their reliability, Dulytek filtration solutions are engineered to balance durability with flow efficiency. By utilizing high-quality, dye-free nylon, these bags resist boiling temperatures and heavy hydraulic pressure, ensuring that your essential oils remain pure, flavorful, and free from particulates during the extraction process.
Eliminate Contaminants and Prevent Blowouts
One of the biggest frustrations in rosin extraction is a filter failure that ruins a batch with plant material, but superior stitching and materials can virtually eliminate this risk.
-
Robust Construction: Dulytek bags feature double-stitching to withstand the immense force applied by a
rosin press, keeping your starting material securely contained while allowing oil to escape freely.
-
Micron Precision: Choose the exact mesh size for your material type; use
25-micron bags for processing fine kief or hash, or opt for
100 to 160-micron bags to effectively filter flower without restricting yield.
-
Food-Grade Safety: Made from dye-free, solvent-free nylon, these filters ensure that no unwanted chemicals or synthetic fibers leach into your concentrate, preserving the natural terpene profile.
Precision Sizing for Every Press
Selecting the correct bag configuration is critical for optimizing plate surface area and ensuring consistent pressure distribution across your puck.
-
Standard Fitment: Available in various dimensions like 2" x 3", 2" x 4", and 3" x 6", these bags are sized to fit popular heating plates perfectly. For best results, pair them with a
pre-press mold to create uniform pucks before insertion.
-
Custom Lengths: For commercial processors or unique plate sizes,
nylon filter tubes allow you to cut the mesh to the exact length required, reducing waste and accommodating larger batches.
-
Seamless Collection: The high-quality mesh works in tandem with
non-stick parchment paper, allowing the extracted rosin to flow away from the heat source quickly for easy collection and curing.
Frequently Asked Questions
What micron size should I use for pressing flower vs. hash?
For pressing flower, a micron size between 90 and 160 is typically recommended to filter out plant material while allowing yield to flow. For finer materials like dry sift, kief, or bubble hash, a smaller micron size such as 25 or 37 is best to ensure particulates are trapped inside the bag. You can learn more about selecting the right mesh in our guide to
micron bags for rosin.
How can I prevent rosin bags from blowing out during a press?
To prevent blowouts, avoid overfilling the bag and leave a small amount of empty space (about 1/4 inch) at the open end. Using a pre-press mold to compact your material before inserting it into the bag also helps create uniform pressure distribution. Additionally, applying pressure gradually rather than all at once is a key
rosin pressing technique to maintain bag integrity.
Why should I turn the filter bag inside out before use?
Turning the bag inside out places the stitching seams on the inside. This helps prevent oil from getting trapped in the seams during extraction, maximizing your final yield and making the collection process easier.
Are Dulytek rosin bags reusable?
While high-quality nylon bags are durable, they are generally designed for single use in rosin extraction. Reusing bags can lead to clogged pores, reduced yield, and a higher risk of contamination or blowouts in subsequent presses.
Do I need to use filter tubes or pre-cut bags?
This depends on your workflow. Pre-cut bags offer convenience and consistency for standard batch sizes. Filter tubes (rolls) offer flexibility, allowing you to cut the mesh to any length, which is ideal for varying batch sizes or specific commercial applications.
What is the difference between nylon and polyester bags?
Nylon is generally preferred for rosin pressing because it stretches slightly under pressure, making it more resistant to blowouts compared to polyester. Dulytek bags are made from food-grade nylon to ensure durability and safety under heat.
