They had no problem getting stuff out of the small plastic box. Tabbed ziplocks work well and are grippable with the gloves. Untabbed ziplocks can be clumsily wrangled open but why bother?

Difficult or Impossible to Use Tools:

• Gripper tool needs bigger holes (glove fingers don't fit)
• Small spatula sucks, can't be gripped with gloves.
• Needlepoint forceps are hard to use and can't handle most sample types
• Larger forceps are no more useful than their widest opening point. The very large ones are simply longer and harder to handle for most samples.

Good Tools:

Reverse forceps are great. The holding upon release feature and the parallel surfaces while in use are the important features.

Large weighing spatula works well for unconsolidated materials and is useable in the gloves.

Since width is really the controlling parameter, we can redesign bigger flat-bladed reverse forceps to handle larger samples.

A fliptop ethanol container rather than a screwcap bottle would be helpful.

Exoenzyme Deployment:
The placement of the soaked filter papers in the sterile foil wrappings on rock surfaces was surprisingly easy. They had no problems with either the folded or the rolled trial versions of the foil.
