304 Stainless Steel Slop Hopper with Removable Grill for Hospital and Laboratory Waste Disposal

Engineered for Controlled Waste Disposal in Clinical Settings

Liquid waste generated in hospitals and laboratories — rinse water from laboratory glassware, cleaning runoff from clinical instruments, contaminated fluids from treatment areas — requires a disposal point that separates solids from liquids before they enter the drainage system. The PQ202 stainless steel slop hopper addresses this requirement through an integrated grill strainer and a deep funnel-shaped bowl, both fabricated from bacteriostatic 304 stainless steel.

At 460 × 460 × 415 mm, the unit occupies a compact footprint that fits into benchtop cutouts or wall-mounted support frames, making it practical for facilities where floor space is allocated to higher-priority equipment. The slop hopper is designed for environments governed by infection control protocols and laboratory waste segregation guidelines, including hospital dirty utility rooms, pathology laboratories, CSSD (Central Sterile Services Department) wash areas, and pharmaceutical production cleanrooms.

The Removable Grill: Solid-Liquid Separation at the Point of Disposal

How the Grill Functions in Daily Use

The grill sits across the hopper opening and acts as a mechanical strainer. When liquid waste is poured into the hopper, the grill captures solid debris — cotton swabs, gauze fragments, instrument tips, broken glass, or precipitated chemical residues — while allowing filtered liquid to pass through the funnel bowl into the drain outlet. This separation prevents drain blockages, reduces biofilm formation in pipework, and supports compliance with facility waste management procedures that prohibit solids from entering the sanitary sewer system.

In hospital sluice rooms, the grill catches items inadvertently dropped during bedpan rinsing or instrument cleaning. In laboratories, it prevents chemical precipitates, filter papers, and small disposable items from entering the drainage network. The grill can be removed, cleaned, and sterilized between uses or at the end of each shift.

Grill Construction and Maintenance

The grill is constructed from stainless steel rods welded into a grid pattern, matching the 304 grade of the hopper body. It is designed to withstand repeated cleaning with hospital-grade disinfectants, autoclave sterilization, and mechanical scrubbing without deformation or corrosion. The removable design allows maintenance staff to lift the grill out for thorough cleaning of both the grid surface and the hopper bowl beneath.

304 Stainless Steel Construction for Corrosion-Resistant Performance

Material Properties for Wet and Chemically Active Environments

The hopper body, grill, and drain connection are manufactured from 304 austenitic stainless steel, a material grade widely specified in healthcare and laboratory construction across Europe, the United States, and ASEAN markets. 304 stainless steel offers resistance to the moisture, cleaning chemicals, and biological fluids encountered in clinical disposal areas. The brushed hairline finish reduces the visibility of water marks and surface scratches that accumulate during daily use, while the non-porous surface inhibits bacterial retention.

Optional 316 Grade for Aggressive Laboratory Conditions

For laboratories handling corrosive chemical waste — including acidic rinse solutions, saline-heavy biological fluids, or pharmaceutical process residues — 316 stainless steel is available. The molybdenum addition in 316 grade provides enhanced pitting corrosion resistance, making it suitable for facilities in coastal regions of the Middle East and Southeast Asia where ambient humidity and salt exposure accelerate surface degradation.

Compact Form Factor for Benchtop and Wall-Mounted Integration

Installation Flexibility Across Facility Types

The PQ202 can be installed in two configurations depending on the room layout and plumbing infrastructure:

• Benchtop mounted: The hopper is set into a stainless steel workbench or existing countertop, with the drain outlet connecting to the plumbing below. This configuration is common in laboratory settings where the hopper is integrated into a washing station alongside sinks and drying racks.

• Wall mounted: The hopper is supported by a wall bracket or gallow frame, keeping the floor area clear for cleaning access. This configuration is typical in hospital dirty utility rooms and sluice areas where floor hygiene is a priority.

The 460 × 460 mm external dimension allows the unit to be specified in renovation projects where existing bench cutouts or wall mounting points are already established, reducing modification costs for contractors working within fixed room dimensions.

Flushing and Drainage Configuration

Cistern and Flush Valve Compatibility

The hopper is designed to work with a flushing cistern or flush valve system that rinses the bowl after each use. The cistern can be specified as an exposed lever-operated type for wall-mounted installations or a concealed type for benchtop installations where the cistern is housed within the cabinet structure below. Flush valve options — including manual lever and sensor-activated types — can be supplied according to the project’s plumbing specification.

Waste Outlet and Trap Connections

The drain outlet is sized to accept standard trap connections, with P-trap and S-trap configurations available to match the building’s waste pipework layout. A strainer basket can be fitted below the grill as a secondary filtration stage for facilities requiring redundant solid capture. The drainage direction — horizontal through the wall or vertical through the floor — can be specified at the time of order to align with existing plumbing points or new-build drawings.

Applications Across Hospital and Laboratory Departments

The PQ202 slop hopper is specified across a range of clinical and research environments:

• Hospital dirty utility rooms and sluice rooms — for disposing of liquid waste from bedpan cleaning, instrument rinsing, and general ward maintenance

• Pathology and histology laboratories — for draining fixative solutions, staining residues, and processing liquids through the grill-strained disposal point

• CSSD wash areas — for capturing solid debris during instrument pre-cleaning before sterilization

• Pharmaceutical cleanrooms — for controlled disposal of process rinse water with solid content separation

• Veterinary clinics and animal research facilities — for safe disposal of biological waste liquids

Customization for Project Specifications and OEM Requirements

XINHE manufactures the PQ202 to project specifications, supporting distributors and contractors who supply hospital and laboratory facilities across Europe, the Middle East, ASEAN, and the Americas. Customizable parameters include:

• Overall external dimensions and bowl depth
