Duratop Epoxy or Even-Flow (EF) polypropylene / polyethylene / poly-resin lab cupsinks are an integral part of the laboratory environment. Used in Fume Hood cabinet / cupboard work bases, or in countertop worksurface / bench topping conditions, cupsinks play an important role in the wet laboratory.

Epoxy cupsinks are corrosion and heat resistant and designed with the idea of quick disposal of liquid waste. Made in all
9 custom Duratop epoxy colors in Oval or Round shapes along with the Earl Walls rectangular cupsink design,

Cupsinks are designed for convenient disposal of liquid waste in fume hoods or on the lab bench top, beit Duratop Epoxy Resin or Resistop or Trespa solid phenolic resin laboratory tops.

Flush mounted cupsinks are the most common installation. This installation requires a rabbeted or rebated cutout in the face of the worksurface. The cupsink is installed so that the outer cupsink rim sets flush with the top of the worksurface or slighly below surface for proper liquid flow during spills. It is installed in a bed of Smooth-On color matched epoxy adhesive.

Alternatively, oval, round or rectangular cupsinks may be mounted under counter with a through hole cutout of a dimension that is approx. 1/8" to 1/4" (3 to 6mm) less than the inside diameter of the cupsink bowl. Attachment again is with Smooth-On epoxy adhesive.

Cupsinks can also be top surface mounted in order to provide a 1/4" (6 mm) high waste barrier around the perimeter of the sink. Top mount (TM) installation requires a simple through hole cutout in the worksurface. Model DER-TM-05 or TS-05 oval cupsink in Epoxy Resin has a raised rim that sits above the surface for containing hazardous spills on the working surface.
