As announced, late last year we invested in tooling to manufacture the new 4-inch HydraSleeves. Well, 3 months later, they have finally arrived, and we are very excited. When they are in development stage we can only estimate volume and fill-rates. Now that the production units are here we can say that these new HydraSleeves actually exceed our expectations with total volume of more than 2.5 liters
The new HS-4-2L are here!
For the time-being we will be offering this new size alongside the old standard 4-inch sleeves. However, when inventory runs out for the old-style 4-inch HydraSleeve, we will be switching users over to this new larger-capacity sleeve.
The new dimensions for the HS-4-2L are 2.9 inches O.D. and 37 inches long. Because of the larger diameter they fill within a 7-foot column and they hold greater than 2.5 liters of sample volume. The lay-flat width is 4.614 inches including the side seams. They easily fit inside a 4-inch well and are more versatile than the old-style 4-inch sleeve which holds ~1.6 liters and was 2.75 inches O.D.
Please keep these new sleeves in mind for your 4-inch wells. Call us for details or order online any time.
