Resealable FEP Duralok™ Bags and Non-stick Storage

FEP Duralok™–A waste-free, storage solution for viscous, greasy, and/or sticky samples

Handling any kind of lab sample requires caution, the right lab equipment, and extreme precision on the part of the lab technician to maintain the integrity of the sample as well as the accuracy of results. A lot of this depends on the nature of the sample–it’s form being the most essential property to be mindful of. Viscous or sticky materials, and liquid and gas samples require more care and watchfulness than a sample that’s in solid or powder form.

  • Pharmaceutical Industry – Medicinal syrups, ointments, gels, resin, and medical marijuana
  • Food Industry – Syrups, jellies, jams, yogurt, and honey
  • Cosmetics Industry– Facial creams, lotions, shaving creams, toothpastes, gels, perfumes, and natural extracts
  • Petroleum Products – Oil and grease
  • Others – Different types of waxes and specialty adhesives

FEP and Kapton® have been available for 50 years and are the preferred choice of sample bag material because of their hydrophobic, non-stick, extreme high and low temperature resistance, chemically inert, and solvent resistant properties.

However, it can be difficult to handle liquids when attempting to heat-seal an FEP or Kapton® bag, causing spillage. This can compromise the integrity of the sample and possibly cause harm to the individual handling the sample if the sample is chemically corrosive, or a biohazard. Loss of these critical and expensive samples or products can result in increased costs. A proper seal cannot be guaranteed every time. Whether the clamping device, machine, or human malfunctions—or these variables combine to create larger errors—the possibilities for errors exists.

New Call-to-action

On the other hand, Duralok™ adds portable, resealable, efficient, and effective enclosure convenience to the durability and versatility of FEP. The use of our resealable Duralok™ bags is not limited to collecting samples and is extended to storing small quantities of viscous products for daily usage such as healing oils, natural ointments, marijuana oils, etc.

For instance, resin, sometimes called “essential oil,” is a gooey, almost adhesive substance that produces all of the medical and euphoric molecules of cannabis. Unless put in a non-stick bag, it would be very difficult to extricate it completely without leaving some of it behind. Shatter, which is one of the most expensive forms of THC, is also a hard, sticky substance that makes clean release almost impossible unless stored properly. Dispensed only in tiny quantities, wastage in the form of residue can prove to be very costly.

Duralok™ bags are an excellent choice to store above mentioned substances or substances with similar properties. Apart from being non-stick, and hydrophobic, Duralok™ also has other versatile benefits such as:

  • Suitable for cryogenic use: -400°F (-240°C)
  • Withstands high-temp applications up to 400°F (200°C)
  • Autoclave resistance
  • Visually clear and provides a high transmittance of UV light
  • High resistance to impact and tearing
  • No electrical tracking, non-wetting, and non-charring
  • Low permeability to liquids, gases, moisture, and organic vapors
  • Weather resistant
  • Chemically inert and solvent resistant to virtually all chemicals (except molten alkali metals, gaseous fluorine, and complex halogenated compounds at elevated pressure and temperature)
  • Low permeability to liquid nitrogen
