Berkshire MS1200.0909.8, MicroSeal 1200, Polyester Knitted, Ultrasonically Sealed, Laundered, 9" x 9", Case of 800
Berkshire MS1200.0909.8, MicroSeal® 1200, Polyester Knitted, Ultrasonically Sealed, Laundered, 9" x 9", Case of 800
The Berkshire MicroSeal® 1200 is a 100% polyester knitted cleanroom wiper engineered specifically for applications where absorbency is the primary performance requirement in ISO Class 3 through ISO Class 5 environments. Unlike standard polyester knitted wipers, the MicroSeal 1200 incorporates a hydrophilic finish that dramatically increases the wiper’s fluid uptake capacity — making it the appropriate choice when a standard knitted polyester wiper isn’t absorbing enough per pass. The ultrasonically sealed edge prevents fiber shedding at the perimeter, and the MS1200.0909.8 is laundered in an ISO Class 3 cleanroom to ensure it arrives with the ionic and particulate cleanliness required for high-classification controlled environments.
MTE Solutions stocks the MS1200.0909.8 in cases of 800 sheets (100 wipes per pack, 8 packs per case). The 9" x 9" format 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 standard knitted polyester wiper isn’t meeting your absorbency requirements, the MicroSeal 1200 is the appropriate upgrade. For the same wiper in bulk/case format, see the MS1200.0909B.8. For the 12" x 12" format, see the MS1200.1212.6.

Frequently Asked Questions
What makes the MicroSeal 1200 different from the Super Polx 1200 or Choice 900?
The MicroSeal 1200 shares the same 100% polyester knitted construction and ISO Class 3 laundering as the Super Polx 1200 and Choice 900, but adds a hydrophilic finish that significantly increases fluid uptake capacity. If your process requires high absorbency in addition to low particle generation — such as frequent solvent wiping or spill control in a high-classification cleanroom — the MicroSeal 1200 is the appropriate specification. The Super Polx 1200 is the better choice when absorbency is not the primary concern and laser-cut edge construction is required.
What is a hydrophilic finish?
A hydrophilic finish is a surface treatment applied to the polyester fibers that increases their affinity for water and water-based fluids. This treatment dramatically increases the wiper’s fluid uptake capacity compared to untreated polyester, which is naturally hydrophobic (water-repelling). The result is a wiper that absorbs more fluid per pass and holds it more effectively during use.
What ISO cleanroom class is the MicroSeal 1200 rated for?
The MS1200.0909.8 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 MS1200.0909.8?
Each case contains 800 wipes — 100 wipes per pack, 8 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.
What is the difference between MS1200.0909.8 and MS1200.0909B.8?
Both are the same MicroSeal 1200 wiper — 9" x 9", 800 sheets per case, hydrophilic finish, ultrasonically sealed, ISO Class 3 laundered. The MS1200.0909.8 comes in individual packs (100 per pack), while the MS1200.0909B.8 is the bulk/case format. Choose based on your dispensing and storage preferences.
