Description générale

For Laboratory Use: AtmosBag glove bag is a flexible, inflatable polyethylene chamber with built-in gloves that lets you work in a totally isolated and controlled environment. It is an inexpensive, portable alternative to the glove box and is well suited to a variety of tasks and materials.

For Field Sampling: AtmosBag slips over the top of cans and drums to blanket with inert gas and isolate vapors and dusts during sampling operations. Minimizes worker exposure and preserves the integrity of the sampled bulk material. AtmosBag serves as a portable laboratory for conducting tests, crime scene investigations, and other applications where a clean isolated chamber is needed.

AtmosBag with Tape-seal closure: The opening of AtmosBag is taped and folded over for a gas-tight seal. Each AtmosBag is supplied with a strip of removable sealing tape.

AtmosBag with Zipper-lock closure: The opening of AtmosBag is closed with a Zipper-lock for a gas-tight seal. The opening is slightly smaller than the width of the bag due to the width of the zipper. Excellent for applications that require repeated access to bag contents and for emergency isolation.

Specifications:
  • Constructed of sturdy 0.003 in. gauge polyethylene that is polished for good clarity
  • Seams are heat-sealed for strength and inflation tested to be leak-free
  • Inlet ports are provided for laboratory gas, vacuum, and electrical lines
  • AtmosBag is not fire-retardant or intended for prolonged contact with solvents, vapors, or chemicals
  • Can be used in an Argon environment
  • Four ports on eachbag. Two on each side of the bag.

  2. I would like to know what kind of port/how do you introduce nitrogen or a continuous flow of inert gas in the chamber. I see ports but how do you connect to a gas tank?

    1. The inlets located on each side of the Atmosbag are used to connect purge gas, vacuum, and power lines. PE connectors are available for making gas and vacuum connections with flexible tubing. A 3-way stopcock may be installed at the bag inlet to control both vacuum and purge gas from a single point. An oil bubbler may be installed at an inlet for continuous purge operation.
      See below for details.
      Installing tubing connectors for Zipper-lock AtmosBags:
      a. Snip the end of the bag inlet with scissors to make a very small opening.
      b. Separate two-piece tubing connector. Position one end inside of the bag inlet and the other outside of the bag inlet.
      c. Push connector pieces together firmly.
      d. Connect AtmosBag to purge gas source and to aspirator or house vacuum with 1 in. i.d. flexible tubing.

  3. I would like to know how to manipulate the atmosphere within the bag (anoxic conditions). Is there any manual or SOP? Thank you, Barbara

    1. Anaerobic chamber - A continuous purge of dry inert gas prevents any traces of moisture or oxygen diffusion into AtmosBag.

      Purge Gas Requirements Inert gas applications: 99.99+% pure nitrogen is an acceptable inert atmosphere for many applications. For more rigorous requirements, use a higher purity grade of nitrogen such as extra dry, prepurified, ultra high purity, or oxygen free. The inert gas can be also be passed through a Drierite gas-drying unit to remove trace amounts of water. Other gas applications: Dust-free filtered air, helium, oxygen, moisturized nitrogen, ordinary air, and carbon dioxide are examples of gases that may be used inside AtmosBag to suit particular experimental requirements.

      Inflation pressure: Do not over inflate AtmosBag with gas as this will make insertion of hands into gloves difficult. TIP: Inflate AtmosBag like a very soft pillow. Alternatively, a continuous gas purge may be employed by connecting AtmosBag to an oil bubbler as a pressure-relief device that maintains a constant pressure inside bag.

    Very awkward and expensive

    Very awkward and expensive. Essentially an exceptionally expensive plastic bag. As you might expect, every time you move your hands the bag changes shape as it has no internal support.

    1. Response from MilliporeSigma:

      Thank you for reaching out and sharing your review with us. The AtmosBag products are an economical alternative to classical rigid glove boxes. The opening (zipper or tape) is large enough to insert various equipement used in controlled atmosphere environments. It can also accomodate a rigid base of offer a more stable working platform. We would encourage you to contact our Technical Service team for assistance in the usage of the AtmosBag products by visiting https://www.sigmaaldrich.com/support/customer-support and submitting and Product Inquiry. Alternatively, we also offer a selection of rigid, more permanant glove box options.
