Berkshire MSSS.1212.12, MicroSeal SuperSorb, Two-Ply Polyester Knitted, Ultrasonically Sealed, Laundered, 12" x 12", Case of 600
Berkshire MSSS.1212.12, MicroSeal SuperSorb®, Two-Ply Polyester Knitted, Ultrasonically Sealed, Laundered, 12" x 12", Case of 600
The Berkshire MicroSeal SuperSorb® 12" x 12" is the highest-absorbency dry wiper in the Berkshire cleanroom lineup in a large-format size, combining two-ply polyester knitted construction with a hydrophilic finish for maximum fluid uptake across a broader wiping surface. The two-ply construction — bonded with pinsonic diamond-pattern bonding — provides significantly higher fluid capacity than a single-ply wiper, while the hydrophilic finish further increases the polyester fibers’ affinity for water and water-based fluids. The ultrasonically sealed edge prevents fiber shedding at the perimeter, and the MSSS.1212.12 is laundered in an ISO Class 3 cleanroom for the ionic and particulate cleanliness required in high-classification controlled environments.
MTE Solutions stocks the MSSS.1212.12 in cases of 600 sheets (50 wipes per pack, 12 packs per case). The 12" x 12" format extends the MicroSeal SuperSorb’s maximum-absorbency performance to larger surface areas — equipment enclosures, large benchtops, and tool housings where a 9" x 9" wiper would require multiple passes. For the same wiper in 9" x 9" format, see the MSSS.0909.8.

Frequently Asked Questions
What is the difference between MSSS.1212.12 and MSSS.0909.8?
Both are the same MicroSeal SuperSorb wiper — two-ply polyester knit, hydrophilic finish, ultrasonically sealed, ISO Class 3 laundered. The MSSS.1212.12 is a 12" x 12" format (600 sheets/case, 50 per pack) versus the 9" x 9" MSSS.0909.8 (800 sheets/case, 100 per pack). 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 MicroSeal SuperSorb different from the MicroSeal 1200 and the Choice SuperSorb?
The MicroSeal SuperSorb combines both absorbency technologies: two-ply construction (like the Choice SuperSorb) and a hydrophilic finish (like the MicroSeal 1200). It is the highest-absorbency dry wiper in the Berkshire lineup. Choose it when neither a single-ply hydrophilic wiper nor a standard two-ply wiper is meeting your absorbency requirements.
What ISO cleanroom class is the MicroSeal SuperSorb rated for?
The MSSS.1212.12 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 MSSS.1212.12?
Each case contains 600 wipes — 50 wipes per pack, 12 packs per case.
Can the MicroSeal SuperSorb be used with IPA or other solvents?
Yes. The hydrophilic finish enhances compatibility with water-based fluids and IPA solutions, and the two-ply construction holds significantly more solvent per wipe before saturation compared to a single-ply wiper. The 100% polyester construction also provides good compatibility with acetone and most common cleanroom solvents.
When should I choose the 12x12 over the 9x9 MicroSeal SuperSorb?
Choose the MSSS.1212.12 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" MSSS.0909.8 is more practical and cost-effective per case.
