We are happy to introduce to you the new "Armored HydraSleeves"
We have applied an additional layer of polyethylene material to the outside of the sleeve, placed some strategic holes to allow air to escape, and have more than doubled the wall thickness of a typical HydraSleeve. Doing so also increases the tensile strength by 10 pounds to better than 35 pounds for the 2-inch 1-liter unit, with similar results on the other sizes.
Standard HydraSleeves are 3 mil thick; the armored sleeves will be 7 mil.
An Armored HydraSleeve could be useful in steel wells, open boreholes, or anywhere you might expect that a HydraSleeve would come in contact with jagged edges or increased potential for abrasion.
They are not available for SuperSleeves because the heavier wall thickness will not allow the sleeve to compress in the bottom of the well very easily. Therefore, even standard top weights should not be used in conjunction with an armored sleeve.
The only drawback is that the total sample volume will be slightly reduced using an armored sleeve. For those that need an extra heavy-duty HydraSleeve the small reduction in sample volume should not prove to be too much of an obstacle. For our 2-inch sleeves you will lose 100 mls of sample volume and for the 4-inch sleeves you will lose 200 mls. Due to the stiffness and additional buoyancy, additional bottom weight will be needed when using Armored HydraSleeves. We would suggest moving one up on the weight size chart to overcome any trapped air between the layers of material, and also to accommodate pulling down the additional buoyancy of the Armored HydraSleeves.
Quantities are available for purchase immediately. They are surcharged the same as any customized HydraSleeve, that is, add $10 to the list price.
