Product Name: Clean foam swab
Product Model: PUF-2581
Purestat® swabs possess good quality and cleaning capability. It is used for cleaning HDD components, optics instrument, medical device or vacuum equipment ect. Swab head construction provides good particle and residue removal without any abrasion. Unique thermal bonding and cleaning process ensure a minimum of particle shedding from foam seal. The swab stem is made from a patented inherently polymer to provide clean, permanent protection without contributing particulate contamination to the clean-room.
- Swab head is made of polyurethane sponge and possesses excellent absorptive capacity
- Thermal bonding head, no chemical bond contamination.
- Convenient for cleaning small slotted and grooved areas.
- Good absorbency and excellent solvent hold
- Low nonvolatile residue
- No contaminating adhesives
- No silicone oil, Amide and DOP
