Pre-Saturated Cleanroom Wipers
Pre-saturation enhances the wiper's absorbent capacity and effectiveness. VALUTEK™ pre-saturated wipes offer consistent performance for your cleanroom operations by reducing airborne contamination from solvent bottle dispensers, chemical storage, and spills. Each wiper dispenser exceeds standard industry quality, preventing solvent evaporation.
Along with our wide variety of stock pre-blended chemistries, we offer custom solvent blends, dispensers, and wiper substrates to meet your unique needs. |
Sterile Cleanroom Wipers
Valutek sterile wipers are ideal for cleaning in aseptic cleanrooms, where maintaining sterility is of optimal importance to your application. All sterile wipers are validated sterile through Cobalt 60 gamma irradiation to a Sterility Assurance Level of 10-6 and includes a Certificate of Sterility based on its lultra-low bioburden levels. |
Non-Woven Cleanroom Wipers
Includes: Rayon, Sontara, Spunlace, and Polypropylene.
Valutek non-woven wipers are made from clean, durable sythetic fibers, and their substrate is high absorbent. These sterile wipers can be used either for cleaning, as they are chmically resistant to most cleaning agents, or for general wiping purposes. They have a high particle count, making them less suitable for ultra-clean environments. |
Knit Cleanroom Wipers
Includes: cotton, nylon, and polyester.
One-ply knit wipers are less absorbent in comparison to non-wovens due to the physical characteristics of the monofilament textile. They are low in particulates and extractables, high in durability and strength, and are recommended for the removal of dry particulates and extractables and contaminants.
Two-ply knits are also low in particulates and extractables, and are more absorbent than standard knit because of the quilted texture's ability to retain liquids. These are the "gold standard" for wipers and are perfectly suited for ultra-clean environments. |
The three attributes to consider when choosing your cleanroom wipes are:
Absorbency
The amount of liquid that a wiper can hold, usually measured in milliliters (ml). It's important to determine the proper amount of absorbency for your specific environment.
Extractables
The amount of elements extracted from the wiper in a wash test, generally measured in Parts Per Million (PPM) or Parts Per Billion (PPB).
Particles
The number of particulates that are released by the material during testing. Polyester usually has the lowest particle rate, follow by nylon, poly cellulose blend, and cotton, which has the highest rate. |
