Berkshire MS1200.1212.6, MicroSeal 1200, Polyester Knitted, Ultrasonically Sealed, Laundered, 12" x 12", Case of 600
Berkshire MS1200.1212.6, MicroSeal® 1200, Polyester Knitted, Ultrasonically Sealed, Laundered, 12" x 12", Case of 600
The Berkshire MicroSeal® 1200 12" x 12" is a 100% polyester knitted cleanroom wiper engineered for applications where high absorbency and broad surface coverage are both required in ISO Class 3 through ISO Class 5 environments. Like the 9" x 9" MS1200.0909.8, the 12" x 12" format incorporates a hydrophilic finish that dramatically increases fluid uptake capacity compared to standard polyester knitted wipers — making it the appropriate specification when frequent solvent application, fluid handling, or spill control on larger surfaces is part of your cleanroom process. The ultrasonically sealed edge prevents fiber shedding at the perimeter, and the wiper is laundered in an ISO Class 3 cleanroom for ionic and particulate cleanliness.
MTE Solutions stocks the MS1200.1212.6 in cases of 600 sheets (100 wipes per pack, 6 packs per case). The 12" x 12" format extends the MicroSeal 1200’s absorbency advantage to larger surface areas — equipment enclosures, 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 MS1200.0909.8 or MS1200.0909B.8.

Frequently Asked Questions
What is the difference between MS1200.1212.6 and MS1200.0909.8?
Both are the same MicroSeal 1200 wiper with hydrophilic finish, ultrasonically sealed edge, and ISO Class 3 laundering. The MS1200.1212.6 is a 12" x 12" format (600 sheets/case) versus the 9" x 9" MS1200.0909.8 (800 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 MicroSeal 1200 different from a standard polyester knitted wiper?
The MicroSeal 1200 incorporates a hydrophilic finish that dramatically increases fluid uptake capacity compared to untreated polyester, which is naturally hydrophobic. This makes it the appropriate choice when a standard knitted polyester wiper isn’t absorbing enough per pass in your process.
What ISO cleanroom class is the MicroSeal 1200 rated for?
The MS1200.1212.6 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 MS1200.1212.6?
Each case contains 600 wipes — 100 wipes per pack, 6 packs per case.
Can the MicroSeal 1200 be used with IPA or other solvents?
Yes. The hydrophilic finish enhances compatibility with water-based fluids and IPA solutions. 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 1200?
Choose the MS1200.1212.6 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" MS1200.0909.8 is more practical and cost-effective per case.
