Polyethylene or Polypropylene is commonly known in the industry as polypro, PP, polyolefin, virgin polyolefin, copolymer material, polyethylene or PE and is widely used as a raw material in the making of high quality laboratory sinks and accessories.
Polyolefin, as a collective term, is the ideal poly material for solving corrosion and chemical attack problems in wet laboratory environments. The PE / PP material has excellent resistance to alkalis, bases and most harsh acids and affords the lab end-user with an aesthetically appealing design, smooth appearance and affordable alternative to stainless steel or some epoxy sinks. The poly sinks offered by Total Lab Solutions (TLS) are sold under the brand name Even-Flow and are considered lightweight, easy to install, corrosion resistant, require no additional under counter bracing and are of the highest quality available in a multitude of shapes and designs.
Special attention needs to be given to the wet environment of laboratories and in particular, the sink area as it is critical to maintaining a stain and corrosion free workplace. In addition to single bowl and double bowl polypropylene (PP) Polyethylene (PE) sinks, Even-Flow sinks are offered in 3” x 6” cup sinks, 3” x 9” cup sinks, 6” round Polypro cup sinks,
as well as several models of ADA compliant poly sinks. All USA sink outlets / wastes are produced as an integral part of the sink unit with a 1 ½” (38mm) national pipe thread outlet.
Imported PP / PE sinks have a separate drain outlet that allows a large quantity of sinks to be shipped nested without the interference of the outlet, thus reducing packaging and shipping costs. Corner drain and center drain sinks are available based on the design criteria, flow of liquids within the sink basin or to maximize the use of the sink bowl.
Even-Flow Poly sinks, like their epoxy counter parts, can be mounted below the work surface as an under counter mount sink or placed into a rebated / rabatted lipped cutout into the surface of the countertop. Another method for some polypro sinks is to flush mount above the counter mounting, using a suitably sized stainless steel flush mounting rim. All sinks are herein listed and the Stainless Steel mounting rims for USA made sinks only, are illustrated below for hanging domestic produced PolyPro sinks.
Polypropylene Even-Flow laboratory sinks, cup sinks, traps, overflows and stoppers are available from Total lab Solutions as a molded, one piece seamless construction of a blend of virgin polyolefin's, polypropylene and polyethylene, to create corrosion resistant products for the laboratory and testing facilities in both the United States and the International market.
Polypropylene sinks by TLS are now available in Black, White and Gray Color. Specify Even-Flow Poly sinks for your laboratory requirements.
