Polypropylene Laboratory Sink Unit with Cabinet

What is the Polypropylene Laboratory Sink Unit with Cabinet?

A polypropylene sink unit has a molded PP basin set into a steel or PP cabinet with a swan-neck tap and waste trap. It is the standard wet station for general chemistry, acid and solvent rinsing at moderate temperatures.

Overview

The basin is molded or welded from polypropylene sheet, resistant to most acids, alkalis and organic solvents, with a service temperature up to about 80–90 °C for short exposure. Typical basin dimensions are 500 × 400 × 300 mm with rounded corners and a central outlet with strainer. The cabinet may be PP or powder-coated steel, with a removable trap panel and adjustable feet. Waste is DN40–DN50 polypropylene with a sealed trap, connecting to a floor or wall drain. A swan-neck mixer tap with laboratory fittings or a separate pure-water tap can be added. Since PP is relatively soft, abrasive pads and heat above its rating should be avoided. The unit is widely used in teaching and analytical laboratories.

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?

• Molded PP basin resistant to most acids, alkalis and solvents
• Service temperature up to about 80–90 °C for short exposure
• Swan-neck mixer tap with laboratory fittings
• DN40–DN50 PP waste with removable trap
• Steel or PP cabinet with access panel
• Optional pure-water tap and pegboard

What are the technical specifications?

A typical polypropylene laboratory sink unit with cabinet configuration offers basin size of 500 × 400 × 300 mm, basin material of Polypropylene, 6–8 mm, cabinet width of 600 / 900 / 1200 mm, tap type of Swan-neck mixer, waste pipe of PP DN40–DN50 and temperature limit of ≈ 80–90 °C (short term). 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 Polypropylene Laboratory Sink Unit with Cabinet is used in general chemistry labs, teaching laboratories, acid and solvent rinsing and quality control labs. 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 Polypropylene Laboratory Sink Unit with Cabinet?

Select PP sink units for general chemistry and teaching where chemical resistance matters more than heat resistance. They are not suited to boiling liquids or autoclave discharge. Specify basin dimensions, cabinet width and material, tap type, waste size, pure-water requirement and any neutralization box.

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.
