Berkshire S1200.0909.8, Super Polx 1200, Polyester Knitted, Laser Cut, Laundered, 9" x 9", Case of 1,200
Berkshire S1200.0909.8, Super Polx® 1200, Polyester Knitted, Laser Cut, Laundered, 9" x 9", Case of 1,200
The Berkshire Super Polx® 1200 is a premium 100% polyester knitted cleanroom wiper representing one of the highest-performance dry wipers in the Berkshire lineup. Laundered in an ISO Class 3 cleanroom and finished with a laser-cut edge, the Super Polx 1200 delivers ultra-low particle generation and exceptional ionic cleanliness — making it the appropriate specification for semiconductor fabrication, advanced optics, life sciences research, and other ISO Class 3 through ISO Class 5 applications where contamination control requirements are at their most stringent. The laser-cut edge produces a cleaner, more precise perimeter than knife-cut or ultrasonically sealed alternatives, minimizing edge fiber generation even under aggressive wiping conditions.
MTE Solutions stocks the S1200.0909.8 in cases of 1,200 sheets (150 wipes per pack, 8 packs per case). The 9" x 9" format is the standard workhorse size for cleanroom bench operations. If your process validation, SOP, or customer specification requires ISO Class 3 laundering and laser-cut edge construction, the Super Polx 1200 is the appropriate wiper. For applications where ISO Class 4 laundering is sufficient, see the Choice 700 (CH709.14) or Choice 900 (CH909.10) as cost-effective alternatives.

Frequently Asked Questions
What makes the Super Polx 1200 different from the Choice 700 or Choice 900?
All three are 100% polyester knitted wipers laundered in ISO Class 3 or 4 cleanrooms, but the Super Polx 1200 uses a laser-cut edge rather than an ultrasonically sealed edge. Laser cutting produces a more precise, cleaner perimeter with minimal edge fiber generation — making it the preferred specification for the most critical ISO Class 3–5 applications. The Choice 900 (ISO Class 3 laundered, ultrasonically sealed) is a cost-effective alternative for applications where laser-cut edge construction is not required.
What is a laser-cut edge?
A laser-cut edge uses a focused laser beam to cut and simultaneously seal the polyester fibers at the wiper’s perimeter. This produces an extremely clean, precise edge with minimal fiber shedding — superior to both knife-cut and ultrasonically sealed edges for the most demanding cleanroom applications.
What ISO cleanroom class is the Super Polx 1200 rated for?
The S1200.0909.8 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 S1200.0909.8?
Each case contains 1,200 wipes — 150 wipes per pack, 8 packs per case.
Can the Super Polx 1200 be used with IPA or other solvents?
Yes. 100% polyester knitted wipers are highly compatible with isopropyl alcohol (IPA), acetone, and most common cleanroom solvents. The laser-cut edge maintains its integrity during solvent wiping without fraying or shedding.
What is the difference between S1200.0909.8 and S1200.0909B.8?
Both are the same Super Polx 1200 wiper — 9" x 9", 1,200 sheets per case, laser cut, ISO Class 3 laundered. The S1200.0909.8 comes in individual packs (150 per pack), while the S1200.0909B.8 is the bulk/case format. Choose based on your dispensing and storage preferences.
