Resealable FEP Duralok™ Bags and Inertness

Posted by Mack Hendrick on Sep 20, 2017 10:10:33 AM

Is Protecting Lab Samples from Contamination a Priority for You?

Modern laboratories are hectic environments with personnel sharing equipment across overlapping workstations that may be near busy areas and limited instruments. Contamination most frequently occurs through avoidable procedural errors. Our FEP Duralok™ bags are resealable, inert, and designed to help you overcome some of these challenges.

Laboratory personnel and field researchers have had a long-standing tryst with sample contamination and understandably so. For instance, you need to secure your sample immediately but the standard protocol when collecting critical or caustic samples is to close the bag using clamps or by heat-sealing the sample bag. These sealing protocols can present a variety of problems. Consider these:

  • Installing and maintaining heat-sealing equipment is expensive, time-consuming, and resource-intensive.
  • Clamping devices and heat sealers create an extra step in your process, increasing the chances of making an error.
  • Certain samples can be difficult to handle such as liquids when attempting to heat-seal them. Avoiding spillage can be difficult under these circumstances.
  • Electricity sources and compressed air may not be readily available or accessible in the field or in special environments, so having a heat-sealing machine can be a challenge.

Resealable FEP Duralok™ bags are the first and only solution on the market that offer convenience, efficiency, and savings in overall costs and resources. Not only does it eliminate the time-delay involved in securing a sample, but the inertness of the bags also maintains the integrity of the sample.

The inert and low permeability qualities of the bag keep the inherent properties of the materials intact and allow for a variety of uses in medical, chemical, and industrial environments.

Ideal for Tissue Storage

Duralok™ technology is ideal for tissue storage. Bones, tendons, and amnions are generally frozen for storage purposes. This tissue must be stored in a dedicated, alarmed freezer/refrigerator and in a container that can withstand a range of extreme cold temperatures. The purity of the sample must be maintained by using storage material that is inert.

FEP Duralok™ bags are inert for non-contaminating samples–including acids, approved to the operating temperatures as low as -400°F, and offer the convenience to reseal immediately after the tissue is placed in the bag.

Some other uses that require inertness of storage material include, but are not limited to:

  • Bags for cryogenic storage of cord blood
  • Bags for storage of eye cores
  • Sampling bags for gases, liquids, and solids
  • Bags for collecting soil samplings
  • Chemical storage bags
  • Chemical waste catch basin liners
  • Stem cell culture bags
