Berkshire DR670.1212.20 Durx 670 12" x 12" Nonwoven Wipes, Qty 3,000 Sheets

The Berkshire Durx® 670 is a hydroentangled poly/cellulose nonwoven wiper engineered for ISO Class 5 through ISO Class 8 cleanroom environments. Constructed from 55% cellulose and 45% polyester, the Durx 670 delivers a balance of absorbency and low particulate generation that makes it a reliable choice for general-purpose surface wiping, equipment cleaning, and process spill control across electronics manufacturing, pharmaceutical production, and medical device assembly. Each wipe is manufactured without binders or surfactants, reducing the risk of ionic contamination on sensitive surfaces. The 12" x 12" format is well-suited for larger surface areas — wiping down equipment enclosures, benchtop surfaces, and larger tool housings where a smaller wipe would require multiple passes.

MTE Solutions stocks the DR670.1212.20 in cases of 3,000 sheets (150 wipes per pack, 20 packs per case). The larger format naturally reduces wipe count per case compared to smaller sizes, making this a practical choice for facilities that prioritize coverage efficiency over raw sheet count. Whether you're cleaning broad work surfaces, wiping down equipment between production runs, or managing larger spills in ISO-classified environments, the 12" x 12" Durx 670 delivers consistent, reliable performance.

Frequently Asked Questions

What is the Berkshire Durx 670 made of?
The Durx 670 is a hydroentangled nonwoven wiper made from 55% cellulose and 45% polyester. This poly/cellulose blend provides good absorbency from the cellulose component and low particle generation from the polyester component.

What ISO cleanroom class is the Durx 670 rated for?
The Durx 670 is suitable for ISO Class 5 through ISO Class 8 environments (equivalent to Federal Standard 209E Class 100 through Class 100,000).

Does the Durx 670 contain binders or surfactants?
No. The Durx 670 is manufactured without binders or surfactants, which reduces the risk of ionic contamination on sensitive surfaces and substrates.

When would I choose a 12x12 wipe over a 9x9?
The 12" x 12" format is best when you're wiping larger surface areas — equipment enclosures, benchtops, or tool housings — where a 9" x 9" would require multiple passes. For precision bench work or component-level cleaning, the 9" x 9" or smaller formats are typically more practical.

How many wipes come in a case of DR670.1212.20?
Each case contains 3,000 wipes — 150 wipes per pack, 20 packs per case.

Can the Durx 670 be used with IPA or other solvents?
Yes. The Durx 670 is compatible with isopropyl alcohol (IPA) and most common cleanroom solvents. For pre-saturated IPA wipes, see the Berkshire SatPax series.
