General cleaning in critical environments and removing particulates
Tip Material: Foam
Medical-grade polyurethane foam has been found to be an excellent tip material for diagnostics. Foam is produced in sheet form in a range of porosity. Common configuration for use in tipped applicators is 100 ppi (pores per inch). Puritan specifies the thickness, width, and porosity of the material purchased from a US manufacturer for use in our medical devices. Other properties are specified as needed, such as absorbency (hydrophilic being very absorbent and hydrophobic being nonabsorbent), open or closed cell, conductive or electrostatic dissipative, or even colored. Your intended use dictates which foam characteristics will work best. For example, polyethylene foam is used for chemical-resistant swabs.
Handle Materials
Puritan utilizes a wide variety of quality swab handle materials for different applications. These include wood, medical grade resins such as polystyrene and polypropylene, paper, aluminum and more.
Created with the patient in mind, many of our swab handles are ergonomically designed for ease of use and patient comfort.
