Description

The sinks and troughs are manufactured from epoxy resin the material that offers a superb combination of features and benefits. It is durable, extremely chemical and stain resistant, mechanically strong and easily cleaned and decontaminated and exhibits good fire resistance, fire propagation and low smoke properties.

Troughs
A number of troughs are available at the sizes as detailed in the table below. These are commonly used at the rear of fume cabinet bases, especially in water wash cupboards. They are also available for mounting into benchtops as required.

Hexagonal Sink
A six sided sink that is designed  specifically for the school laboratory so that up to six students can have easy access to the sink. This can be fitted as an underslung or a drop-in fitment into a worktop of any material. The sink measures 679 x 779 x 180 mm.

Circular Sinks
Two sizes and configurations of sink are produced.

1. The SC8-C sink is a small circular sink 300 mm diameter x 150 mm deep with steep sides.

2. The C-40 sink is 400 mm diameter x 188 mm deep and is hemispherical in design for an especially attractive appearance. This sink can also be used as a drop-on or drop-in type fitment.

D-Sinks
A pair of sinks that are cast in an innovative D-shape. These sinks are designed for use as drop-ons but can also be used as drop-ins and overhang fitment sinks.

  • Sink length and width dimensions given are nominal sizes only. There can be slight variations form sink to sink due to the nature of epoxy resin.
  • Outlet position assumes that the sink / trough is oriented with the longer side facing the front of the worktop.
  • Sink weight will vary with colour. Weights shown are for Grey.
  • All dimensions in millimetres.
