Polypropylene Multi-Purpose Tray United Scientific – 18″ x 14″ x 3″

Description

Product Overview

The United Scientific polypropylene multi‑purpose tray is engineered to meet the demanding needs of modern laboratories, research facilities, and educational science classrooms. Measuring 18″ x 14″ x 3″, the tray offers a generous surface area while maintaining a compact footprint that fits easily into standard storage cabinets and autoclave racks. Constructed from high‑grade, food‑safe polypropylene, the material provides excellent resistance to a wide range of chemicals, including acids, bases, solvents, and disinfectants, ensuring that the tray will not degrade or leach contaminants during repeated cleaning cycles. The molded design incorporates tapered walls that allow trays to nest securely when not in use, reducing shelf space requirements and simplifying inventory management. Integrated ergonomic handles give users a firm grip for safe transport, and the smooth, non‑porous surface prevents microbial growth, making the tray ideal for sterile environments. The tray’s dimensional stability is maintained even after exposure to temperatures ranging from -20°C freezers to 200°C ovens, allowing it to be used for both cold storage of reagents and high‑temperature sterilization processes. Its lightweight construction, at just 2.55 pounds, reduces the physical strain on laboratory personnel while still providing the robustness required for daily handling. The clear, transparent polypropylene also enables quick visual inspection of contents without the need to remove items, streamlining workflow and reducing the risk of cross‑contamination.

Beyond its core functional attributes, the United Scientific tray incorporates thoughtful design details that enhance usability and safety. The raised lip around the perimeter prevents liquids from spilling over the edge during washing or when placed on inclined surfaces, protecting workbenches and reducing cleanup time. The tray’s surface is engineered to be dishwasher safe, allowing for rapid turnaround between experiments, and it can be autoclaved without warping, ensuring that sterility can be achieved quickly and reliably. The product complies with ASTM standards for laboratory plasticware, giving confidence to quality‑focused institutions that the tray meets rigorous performance criteria. Additionally, the tray is compatible with a variety of laboratory accessories, such as silicone mats, filter paper, and specimen containers, making it a versatile platform for diverse protocols ranging from microbiology plating to chemical synthesis. With a best‑seller rank of #30 in the Lab Trays category and a 4.9‑star rating from twelve verified customers, the tray has demonstrated consistent satisfaction among professionals who demand dependable, cost‑effective solutions.

The manufacturing process for this tray follows ISO 9001 quality management protocols, ensuring consistent material properties across each production batch. Raw polypropylene resin is sourced from vetted suppliers who provide certificates of analysis confirming purity and absence of heavy metals. During molding, temperature and pressure are precisely controlled to achieve uniform wall thickness and eliminate internal stresses that could lead to cracking under load. Post‑production, each tray is inspected for dimensional accuracy, surface defects, and mechanical integrity using calibrated equipment. This rigorous oversight guarantees that every unit delivered to the customer meets the exact specifications outlined in the product data sheet, providing confidence in performance and longevity.

Usage

Laboratory technicians frequently employ this tray for sterilizing glassware after autoclave cycles, taking advantage of its heat‑resistant properties and chemical inertness. The tray’s ample surface area accommodates multiple beakers, flasks, and pipette racks simultaneously, allowing for batch processing that saves time and reduces the number of handling steps. In educational settings, instructors use the tray to organize classroom supplies, such as petri dishes, test tubes, and microscope slides, providing students with a clean, orderly workspace that reinforces good laboratory practices. The tray also proves valuable in field research where portable, lightweight equipment is essential; its sturdy handles enable easy packing into field kits, and its resistance to harsh environmental conditions ensures that samples remain protected during transport. For quality control laboratories, the tray can serve as a containment platform for hazardous waste segregation, as the polypropylene material does not react with most waste streams, and the raised lip helps prevent accidental spills. In pharmaceutical manufacturing, the tray’s non‑porous surface supports compliance with Good Manufacturing Practice (GMP) guidelines by minimizing the risk of product contamination. Moreover, the tray’s compatibility with standard laboratory ovens and incubators allows it to be used for drying delicate components, such as filter membranes or precision instruments, without fear of deformation. Its versatility extends to home‑based hobbyist experiments, where the same durability and ease of cleaning make it a practical addition to any serious maker’s toolkit.

Because the tray is designed to nest, laboratories can store multiple units in a single stack, freeing valuable bench space for other critical equipment. The lightweight nature of the tray also reduces the risk of repetitive strain injuries for staff who frequently move trays between workstations, a consideration that aligns with occupational health and safety standards. When used in conjunction with disposable liners, the tray can be quickly converted into a single‑use containment system, further enhancing biosafety in high‑throughput environments. The clear polypropylene construction also aids visual monitoring of reaction progress, enabling technicians to quickly assess color changes, precipitate formation, or phase separation without opening containers, thereby maintaining a closed system and preserving sample integrity.
