Material Specification for PP Laboratory Workbenches

I. External Dimensions (Standard)

External dimensions: L × D 530 × H 775/825 (excluding the worktop); the laboratory bench is assembled from individual cabinet units and comes equipped with double cabinets, single cabinets, water cabinets, corner cabinets, main‑unit cabinets, open spaces, keyboard stations, single‑drawer units, and more—dimensions are all customizable.

II. Main Cabinet Parameters

Made from high‑quality, virgin PP (polypropylene) sheets welded with matching‑color, same‑material welding rods, this product offers excellent resistance to strong acids and alkalis as well as superior weatherability. The left and right side panels feature integrally formed, arc‑shaped columns that are bent and welded in one piece, creating a “U‑shaped” structure that ensures exceptional stability and robustness. A maintenance access panel is provided on the rear panel for convenient troubleshooting. Designed for easy disassembly and assembly, it withstands temperatures up to 100°C, resists corrosion, does not rust, and boasts a long service life, making it an outstanding choice for chemical laboratory equipment.

III. Countertop

The worktop can be formed by bending PP polypropylene, offering excellent resistance to strong acids and alkalis (available in thicknesses of 8 mm, 10 mm, 12 mm, 20 mm, etc.); alternatively, it may feature a solid-core physicochemical board worktop (available in thicknesses of 12.7 mm, 16 mm, 19 mm, 25 mm, etc.), which provides impact resistance, corrosion resistance, and meets the E1 formaldehyde emission standard.

IV. Plastic Components

The door handles are PVC, in a deep gray, with a simple linear design that enhances the cabinet’s clean, elegant appearance. The hinges are concealed, made of dark gray PP, offering excellent resistance to acids and alkalis, easy installation, adjustable gap settings, and high practicality, with a 180-degree opening angle. The drawer slides are integrally molded from plastic using the same material as the cabinet body, ensuring smooth, effortless extension, robust load-bearing capacity, and long service life, while also providing superior resistance to strong acids, alkalis, and corrosion.

Ventilation Cabinet Material Specification

I. External Dimensions (Standard)

Overall dimensions of the upper and lower cabinets: W 1200, 1500, 1800 × D 850 × H 2350;

Upper cabinet dimensions: W 1200, 1500, 1800 * D 850 * H 1650;

Lower cabinet dimensions: W 1200, 1500, 1800 * D 790 * H 700;

II. Main Cabinet Parameters

The upper and lower cabinets feature a modular, disassemblable structure. The panels are crafted from 5–8 mm thick PP polypropylene sheets in ivory white (with an optional porcelain‑white option), joined in a seamless, full‑panel design. After precise CNC machining, the panels are welded together, delivering excellent resistance to strong acids and alkalis. The lower cabinet’s welds incorporate edge‑folding reinforcements—such as “mouth‑type,” “U‑type,” and “T‑type” profiles—ensuring structural stability and robust load‑bearing capacity. The left and right side panels are integrally formed with rounded, arc‑shaped edges that connect to the front left and right uprights, providing enhanced stability and rigidity. This curved‑edge design promotes steady airflow, minimizes gas leakage, and safeguards operator safety. Additionally, the interior panel incorporates a one‑piece, molded maintenance access window, facilitating convenient inspection and servicing of water, electrical, and pneumatic lines.

III. Window Lifting System Configuration

The window sliding door is a vertically sliding type, featuring a balanced‑position mechanism that allows it to stop at any desired operating height. Counterweights are mounted directly within the counterweight track on the back panel, minimizing space consumption and ensuring smooth, effortless operation of the glass door. The window handle is integrally molded from aluminum alloy profiles and incorporates a glass insert at its base, offering exceptional hardness, high‑temperature resistance, and excellent resistance to corrosion and deformation. On both sides, PVC clamping strips are extruded as a single piece and seamlessly integrated with the glass edges via an embedded joint, providing low friction while enhancing safety and durability. The window glass is 5 mm thick tempered glass, bearing the 3C safety mark; it boasts superior strength, excellent flexural resistance, and, upon breakage, does not produce sharp, angular fragments. The window’s lifting and balancing system employs a synchronized design: synchronous‑belt drive ensures precise positioning, exerts minimal axial load, and delivers outstanding wear resistance and aging performance.

IV. Gas Diversion Device

The deflector is fabricated from 5-mm-thick PP polypropylene sheet, offering exceptional resistance to acids and alkalis as well as superior corrosion resistance. It is formed by a single sheet that folds and unfolds in one piece; when installed at the rear and upper portion of the work area, it creates an air chamber between the work space and the exhaust duct connection, ensuring the uniform and efficient removal of contaminated gases with varying specific gravities. The deflector is mounted to the cabinet using a PP mounting base, allowing for repeated disassembly and reassembly to facilitate easy cleaning of the cabinet interior.

V. Venting Device

The exhaust outlet features an integrally molded, injection‑molded air‑collection hood made of PP. Its conical collection angle and streamlined design ensure excellent uniformity in air collection and low pressure loss, while minimizing gas turbulence. The bottom inlet is a rectangular opening, and the top outlet is a 250 mm diameter circular port, connected via a sleeve.

VI. Optional Worktop Options

The standard countertop is made of one-piece PP polypropylene (with optional options such as phenolic resin, marble, or ceramic), featuring a rounded‑arc design. It includes water‑deflecting edges on all four sides, with the front edge shaped in a gentle curve; the front water‑deflecting lip is thickened to 32 mm, providing high strength, excellent resistance to acids and alkalis, superior impact resistance, and easy cleaning, effectively preventing the spillage of hazardous liquids.

VII. Plastic Components

The lower cabinet door handles feature PVC straight‑line pulls, offering simple installation and a sleek, understated look. The door hinges are concealed PP hinges, which are easy to install, allow for adjustable gap settings, and deliver a clean, elegant appearance.

VIII. Hardware Accessories

Hardware screw components are galvanized for rust resistance or made of stainless steel, offering excellent resistance to acid and alkali corrosion.
