Berkshire CHSS09.14, Choice SuperSorb 9" x 9", Case of 1,050
The Berkshire Choice SuperSorb is a two-ply 100% polyester knitted cleanroom wiper engineered for applications where absorbency is the primary performance requirement. Unlike single-ply knitted wipers, the SuperSorb features a pinsonic diamond-pattern bonding that fuses two layers of polyester together, creating a wiper with significantly higher fluid uptake capacity while maintaining the low-particle generation characteristics of 100% polyester construction. The ultrasonically sealed edge prevents fiber shedding at the perimeter, and the CHSS09.14 is rated for ISO Class 3 through ISO Class 5 environments — making it suitable for high-classification cleanrooms where both absorbency and contamination control are critical.
MTE Solutions stocks the CHSS09.14 in cases of 1,050 sheets (75 wipes per pack, 14 packs per case) in standard pack format. The 9" x 9" size covers the standard cleanroom bench footprint. If your process involves frequent fluid handling, solvent application, or spill control in an ISO Class 3–5 environment and a single-ply wiper isn’t absorbing enough per pass, the SuperSorb is the appropriate upgrade. For the same wiper in bulk/case format, see the CHSS09B.14.

Frequently Asked Questions
What makes the SuperSorb different from the Choice 700?
The Choice SuperSorb is a two-ply wiper with pinsonic diamond-pattern bonding, which gives it significantly higher absorbency than the single-ply Choice 700. Both are 100% polyester with ultrasonically sealed edges and ISO Class 3–5 ratings, but the SuperSorb is the right choice when fluid uptake per wipe is the primary concern.
What is pinsonic diamond-pattern bonding?
Pinsonic bonding uses heat and pressure applied through a diamond-patterned die to fuse the two polyester layers together at regular intervals. This creates a stable two-ply structure that holds its shape during use and distributes absorbed fluid evenly across the wipe surface.
What ISO cleanroom class is the Choice SuperSorb rated for?
The CHSS09.14 is rated for ISO Class 3 through ISO Class 5 environments (equivalent to Federal Standard 209E Class 1 through Class 100).
What is the difference between CHSS09.14 and CHSS09B.14?
Both are the same wiper — two-ply polyester SuperSorb, 9" x 9", 1,050 sheets per case. The CHSS09.14 comes in standard individual packs (75 per pack), while the CHSS09B.14 is the bulk/case format. Choose based on your dispensing and storage preferences.
How many wipes come in a case of CHSS09.14?
Each case contains 1,050 wipes — 75 wipes per pack, 14 packs per case.
Can the SuperSorb be used with IPA or other solvents?
Yes. 100% polyester construction makes the SuperSorb highly compatible with isopropyl alcohol (IPA), acetone, and most common cleanroom solvents. The two-ply construction also means it holds more solvent per wipe before saturation.
