Solving a 50-Year-Old Problem

Once you put your critical or caustic sample inside your field sample bag, how do you close it? Perhaps you’ve been using the standard protocol of either a clamp made of some other material, or have invested in expensive heat-sealing equipment that requires time, training, and resources to operate. Either option creates an extra step in your process, can present a rash of problems, and is inconvenient to use.

What Does that Mean for You?

Durability, and a secure liquid and airtight enclosure for your critical or caustic sample bags—though not rated for pressure. It means no more clamps or expensive heating equipment or extra time and resources spent to properly seal your field or lab sample bags.
