The range offers our most versatile solution for the efficient stocking and fitting of laboratory sinks. The range is designed so that the same sink can be fitted from the top side of the worktop into a rebated cut out for drop-in fitment or they can be screwed and bonded to the underside of a worktop using the integral flange for an undermount fitment.
When fitted as a drop-in, all sinks are self-supporting on the integral flange. The drop-in fitment is particularly suitable for use with laminate worktops as the less resistant core material of the laminate is covered by the flange of the epoxy resin sink.
Where sinks are factory fitted to Simmons’ own worktops they can be provided undermounted with the worktop overhanging or fitted flush. Flush-fitment involves rebating the sink into the underside of the worktop and then machining the worktop to give a smooth, crevice free joint. This can only be done in the Simmons factory when fitting to a Simmons epoxy worktop.
All sinks are moulded in one piece with a smooth, hardwearing and easy to clean and decontaminate inside surface. They are light and easy to handle.

As with all worktops a reasonable standard of laboratory housekeeping will help to keep the worktops in good condition. All spillages should be cleaned up as soon as possible. Staining agents and aggressive chemicals should not be allowed to sit in contact with the tops for a prolonged period of time.
Areas of chemical attack or staining can be removed with a polishing compound or very fine abrasive paper, but it should be stressed that this will alter the finish of the surface. Performance will not be affected.
The use of a wax furniture polish will help to retain the gloss finish.
Components should not be exposed to dry-ice or liquid nitrogen and heat insulation pads should be placed between a top and a steambath or hotplate to prevent thermal stress.
List of Tools and Equipment required:-
Overhang/Underslung sinks which are supplied loose can be fitted to a worktop with a suitably sized cut out (please ring for recommendation if unsure). Clearance holes for self-tapping screws should be drilled through the sink flange with a masonry drill, and the worktop drilled with a pilot hole to accept same. A layer of silicone sealant should be applied to the flange and the sink should be screwed securely into place. Excess silicone should be removed before it cures.
Sinks can be supplied complete with a chemically resistant polypropylene waste in grey, white or black is required. Wastes have a 73mm diameter flange and a 1½ inch BSP tail and will connect to the relevant Vulcathene industrial waste components. These can also be combined with a standing waste tube or an overflow kit.
