Stainless Steel Laboratory Sink Unit

What is the Stainless Steel Laboratory Sink Unit?

A stainless steel sink unit has a welded 304 or 316 basin and optional drain board in a stainless or steel cabinet. It suits biology, pharmaceutical and food laboratories that need frequent disinfection and hot water use.

Overview

Basins are pressed or welded from 1.2–1.5 mm AISI 304 or 316 sheet, with polished seams and coved corners of 10–20 mm radius. They tolerate hot water, steam condensate and autoclave rinse, and they resist ethanol, hypochlorite and quaternary ammonium disinfectants when rinsed. Typical size is 500 × 400 × 250 mm, with a drain board of 400–600 mm. Stainless is unsuitable for regular contact with hydrochloric acid, strong chlorides or hydrofluoric acid. Taps can be elbow-operated, foot-operated or infrared for hands-free operation in microbiology. Sound-deadening undercoating reduces splash noise, and a removable trap with stainless strainer simplifies cleaning. The design is hygienic but more costly than polypropylene.

How does it work?

A laboratory sink unit combines a basin, a worktop or drain board, taps, a waste outlet with trap, and often a cabinet beneath. Basins are molded polypropylene, cast epoxy resin or fabricated stainless steel, with depths of 200–350 mm and capacities of 15–40 litres. Taps include gooseneck mixers, swan-neck or pillar types, with optional pure-water, foot-operated or elbow-operated controls. The waste outlet drains through a chemical-resistant trap, typically polypropylene, sized DN40–DN50, with a removable strainer. Units are designed with slopes toward the outlet and a drip groove, and some include neutralization boxes for acid waste or a pegboard for drying glassware. Water supply and waste connections must respect backflow prevention and local plumbing codes.

What are the key features?

• Welded 304 or 316 stainless basin with coved corners
• Drain board options 400–600 mm wide
• Elbow, foot or infrared tap for hands-free use
• Tolerates hot water and autoclave rinse
• Sound-deadening undercoat reduces splash noise
• Removable trap with stainless strainer

What are the technical specifications?

A typical stainless steel laboratory sink unit configuration offers basin size of 500 × 400 × 250 mm, material of AISI 304 or 316, 1.2–1.5 mm, corner radius of 10–20 mm, drain board of 400–600 mm wide, tap type of Elbow / foot / infrared and temperature limit of ≥ 100 °C. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Stainless Steel Laboratory Sink Unit is used in microbiology laboratories, pharmaceutical QC, food testing laboratories and cleanroom support areas. Across the wider Sink Units class, laboratories also deploy it for glassware washing, hand washing stations and sample preparation.

Which standards and certifications apply?

Relevant standards and methods include SEFA 8 (laboratory grade casework), EN 14056 (laboratory furniture design and installation), EN 13150 (laboratory workbenches, finish tests), GB 24820 (laboratory furniture) and EN 274 (waste fittings for sanitary appliances, reference). Certification candidates for this model are ISO 9001 manufacturing, SEFA 8 test report and WRAS-type water fitting approval for taps; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Plan water supply, waste and isolation valves early, and give sink units access panels for trap cleaning. Install backflow prevention on the water supply, and route waste to a chemical-resistant drain system or neutralization tank where acids or solvents are present. Seal the sink rim to the worktop with silicone to prevent leaks. Do not pour hazardous solvents or heavy metals down the drain, and follow local wastewater regulations. Flush traps daily, clean strainers weekly, and inspect seals and taps every six months. Provide eyewash stations within easy reach of sinks used for chemical work.

How do I select the right Stainless Steel Laboratory Sink Unit?

Select stainless sinks for biology, pharmaceutical and food labs where disinfection, hot water and hygiene dominate. Avoid them for regular hydrochloric acid or strong chloride work. Specify grade, basin and drain board size, tap type, cabinet material, waste connection and cleaning agents used.

How does it compare with other Sink Units variants?

Select the basin material first. Polypropylene suits general chemistry, acids, alkalis and solvents at moderate temperature; epoxy resin suits heavier use and hot liquids; stainless steel suits biology, pharmaceutical and food labs that need frequent disinfection. Then choose size: single-bowl units save space, double-bowl units separate rinsing and soaking, and cup sinks fit fume hoods and small benches. Consider tap type (hands-free for microbiology), pure-water supply, drain board and pegboard requirements, and neutralization of acid waste. Check plumbing connections, hot-water supply and accessibility height. Confirm the unit is compatible with local wastewater discharge rules and the chemicals in use.
