Sinktops

Fabricated Sinktops

If standard moulded single or double drainer sinktops are not suitable then we can fabricate sinktops to other sizes and configurations to suit your requirement. Using 15 mm thick sheet and combining it with various sinks from our standard range, drainer types (moulded drainers, drainer board or machined drainer grooves) and edgings or upstands we should be able to fabricate whatever sinktops you may need.

Please submit a drawing of the sinktop that you require and we will advise how close to that specification we are able to get.

Our standard colours are:

Installation and Maintenance

General Maintenance

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.

Wastes and overflows

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.
