Berkshire CHSS12.12, Choice SuperSorb 12″ x 12″, Case of 900
Berkshire CHSS12.12, Choice SuperSorb 12" x 12", Case of 900
The Berkshire Choice SuperSorb 12" x 12" is a two-ply 100% polyester knitted cleanroom wiper engineered for applications that require both high absorbency and broad surface coverage in ISO Class 3 through ISO Class 5 environments. Like the 9" x 9" SuperSorb, the CHSS12.12 features pinsonic diamond-pattern bonding that fuses two layers of polyester together for significantly higher fluid uptake than a single-ply knitted wiper, with an ultrasonically sealed edge to prevent fiber shedding at the perimeter. The 12" x 12" format extends that performance to larger surface areas — equipment enclosures, benchtops, and tool housings where a 9" x 9" wiper would require multiple passes to cover the same area.
MTE Solutions stocks the CHSS12.12 in cases of 900 sheets (75 wipes per pack, 12 packs per case). If your process involves frequent fluid handling or solvent application on larger surfaces in a high-classification cleanroom, the 12" x 12" SuperSorb combines the absorbency advantage of two-ply construction with the coverage efficiency of a larger format — reducing the number of wipes needed per task and minimizing the risk of cross-contamination from repeated passes.

Frequently Asked Questions
What is the difference between CHSS12.12 and CHSS09.14?
Both are the same two-ply polyester SuperSorb construction with pinsonic bonding and ultrasonically sealed edges. The CHSS12.12 is a 12" x 12" format (900 sheets/case) versus the 9" x 9" CHSS09.14 (1,050 sheets/case). Choose the 12" x 12" when you need broader surface coverage per wipe; choose the 9" x 9" for standard bench-level work.
What makes the SuperSorb different from a standard single-ply knitted wiper?
The SuperSorb is a two-ply wiper with pinsonic diamond-pattern bonding, giving it significantly higher fluid uptake capacity than a single-ply knitted wiper like the Choice 700. Both are 100% polyester with ultrasonically sealed edges, but the SuperSorb is the right choice when absorbency per wipe is the primary requirement.
What ISO cleanroom class is the CHSS12.12 rated for?
The CHSS12.12 is rated for ISO Class 3 through ISO Class 5 environments (equivalent to Federal Standard 209E Class 1 through Class 100).
How many wipes come in a case of CHSS12.12?
Each case contains 900 wipes — 75 wipes per pack, 12 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 holds more solvent per wipe before saturation compared to a single-ply wiper.
When should I choose the 12x12 SuperSorb over the 9x9?
Choose the CHSS12.12 when your wiping tasks involve larger surface areas — equipment enclosures, benchtops, or tool housings — where a 9" x 9" wiper would require multiple passes. For standard bench-level or component cleaning, the 9" x 9" CHSS09.14 is more practical and cost-effective per case.
