Berkshire MS1200.0909B.8, MicroSeal 1200, Polyester Knitted, Ultrasonically Sealed, Laundered, 9" x 9" (Bulk/Case), Case of 800
Berkshire MS1200.0909B.8, MicroSeal® 1200, Polyester Knitted, Ultrasonically Sealed, Laundered, 9" x 9" (Bulk/Case), Case of 800
The Berkshire MicroSeal® 1200 Bulk is the same 100% polyester knitted cleanroom wiper as the MS1200.0909.8 — hydrophilic finish, ultrasonically sealed edge, laundered in an ISO Class 3 cleanroom, rated for ISO Class 3 through ISO Class 5 environments — packaged in bulk/case format rather than individual packs. The hydrophilic finish dramatically increases fluid uptake capacity compared to standard polyester knitted wipers, making the MicroSeal 1200 the appropriate choice when a standard knitted polyester wiper isn’t absorbing enough per pass. The bulk format eliminates the per-pack packaging layer, reducing dispensing time in high-throughput environments and simplifying storage when individual pack traceability isn’t required by your SOP.
MTE Solutions stocks the MS1200.0909B.8 in cases of 800 sheets in bulk/case format. If your facility dispenses wipers from a central supply and your process involves frequent fluid handling or solvent application in an ISO Class 3–5 environment, the bulk MicroSeal 1200 delivers high-absorbency performance at a lower per-wipe cost than the standard-pack MS1200.0909.8. For the same wiper in individual packs, see the MS1200.0909.8. For the 12" x 12" format, see the MS1200.1212.6.

Frequently Asked Questions
What is the difference between MS1200.0909B.8 and MS1200.0909.8?
The wiper is identical — MicroSeal 1200, 9" x 9", 800 sheets per case, hydrophilic finish, ultrasonically sealed, ISO Class 3 laundered. The MS1200.0909B.8 is the bulk/case format with no individual pack packaging, while the MS1200.0909.8 comes in individual packs of 100. Choose bulk if your facility dispenses from a central supply or doesn’t require per-pack lot tracking; choose standard packs if individual pack traceability is part of your SOP.
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 MS1200.0909B.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 MS1200.0909B.8?
Each case contains 800 wipes in bulk/case format — no individual pack subdivisions.
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.
Is the bulk format less expensive than the standard pack?
The bulk format (MS1200.0909B.8) is typically priced lower per wipe than the standard pack (MS1200.0909.8) due to reduced packaging. If per-pack traceability is not required by your process, the bulk format is the more cost-effective option.
