Berkshire DR670.1818.10 Durx 670 18" x 18" Nonwoven Wipes, Qty 1,500 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 18" x 18" is the largest format in the Durx 670 line — designed for high-coverage applications where a single wipe needs to cover broad equipment surfaces, large benchtops, or floor-level spill control in ISO-classified environments.

MTE Solutions stocks the DR670.1818.10 in cases of 1,500 sheets (150 wipes per pack, 10 packs per case). The large format makes this the right choice when coverage per wipe matters more than sheet count — ideal for facilities that wipe down large equipment enclosures, cleanroom walls, or oversized work surfaces as part of their standard cleaning protocol. If your process involves large-area wiping tasks, the 18" x 18" Durx 670 eliminates the need for multiple smaller wipes and reduces the risk of cross-contamination from repeated passes.

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 use an 18x18 wipe instead of a smaller size?
The 18" x 18" format is best for large-area wiping tasks — equipment enclosures, cleanroom walls, oversized benchtops, or floor-level spill control — where a smaller wipe would require multiple passes and increase the risk of cross-contamination. For bench-level or component work, the 9" x 9" or smaller formats are more practical.

How many wipes come in a case of DR670.1818.10?
Each case contains 1,500 wipes — 150 wipes per pack, 10 packs per case. This is the largest size in the Durx 670 line.

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.
