Polypropylene Jar Qorpak PLC-03720 32oz Drying with White Unlined Cap

Description

Product Overview

The Qorpak PLC-03720 is a high‑performance polypropylene jar designed specifically for laboratory drying and sample preservation. Constructed from food‑grade, chemically resistant polypropylene, the jar offers a robust barrier against moisture, solvents, and a wide range of laboratory reagents. With a generous 32 oz (approximately 950 ml) internal volume, the container provides ample space for bulk samples, reagents, or dried solids, while maintaining a compact footprint that fits comfortably on standard bench tops and shelving units. The jar features a smooth, seamless interior that minimizes particle adhesion and simplifies cleaning procedures, reducing the risk of cross‑contamination between experiments. Its natural, uncolored finish delivers a neutral background that enhances visual inspection of contents and supports easy labeling with permanent markers or barcode stickers. The included white unlined cap is molded from the same polypropylene material, ensuring a tight, leak‑proof seal that resists degradation from repeated opening and closing cycles. The cap’s low‑profile design reduces the overall height of the jar, allowing for efficient stacking and storage in laboratory cabinets. Precise dimensions of 119 mm outer diameter and 96 mm height provide a standardized size that aligns with common laboratory equipment, such as drying ovens, incubators, and rotary shakers. The jar’s lightweight construction, weighing only 2.8 kg per case of 24, facilitates bulk handling and reduces shipping costs. Manufactured by Qorpak, a trusted name in laboratory supplies, the PLC‑03720 meets stringent quality standards and is backed by a comprehensive warranty that guarantees performance consistency over the product’s lifecycle.
Beyond its basic dimensions, the PLC‑03720 jar is engineered to meet the demanding conditions of modern laboratory workflows. The polypropylene polymer is selected for its high melt flow index, which enables the creation of thin yet uniformly thick walls that provide excellent impact resistance without adding unnecessary weight. This balance of strength and lightness allows the jar to be safely handled by a single operator, even when filled to capacity, reducing the risk of accidental drops that could compromise sample integrity. The material’s low moisture absorption rate ensures that the jar does not retain residual water after drying cycles, thereby preventing unwanted dilution of subsequent samples. Additionally, the jar’s surface is treated with a proprietary anti‑static coating that minimizes static charge buildup, a critical factor when working with fine powders or volatile compounds that can be attracted to charged surfaces. The white unlined cap is fabricated using an injection‑molding process that guarantees a seamless fit with the jar’s threading, eliminating gaps that could lead to vapor escape. The cap’s interior is smooth, allowing for easy removal of any residue that may accumulate during repeated use. For laboratories that require traceability, the jar’s exterior can be easily engraved or labeled with laser‑etched barcodes, batch numbers, or safety warnings without compromising the integrity of the polymer. All components comply with ISO 9001 quality management standards, and the product is certified free from BPA and phthalates, making it suitable for applications that demand strict chemical purity.
Operational flexibility is further enhanced by the jar’s ability to withstand a wide temperature range, from –20 °C up to 150 °C, without deformation or loss of sealing performance. This makes the PLC‑03720 suitable for both low‑temperature storage of temperature‑sensitive reagents and high‑temperature drying processes in laboratory ovens. The jar’s design also incorporates a recessed lip around the opening, which provides a convenient grip for pipettes, spatulas, or tweezers, reducing the chance of slippage during sample transfer. For users who need to integrate the jar into automated workflows, the uniform dimensions allow for easy accommodation within robotic arm grippers and carousel systems. The jar’s transparent sidewalls, though naturally colored, permit visual monitoring of sample status without the need to open the container, thereby preserving the internal environment and minimizing exposure to ambient humidity. Overall, the combination of material robustness, ergonomic design, and compatibility with standard laboratory equipment positions the Qorpak PLC‑03720 as a versatile solution for diverse scientific applications.

Usage

The PLC‑03720 jar excels in a variety of laboratory environments where reliable drying and secure storage are essential. Researchers commonly employ the jar to dry organic solvents, filter residues, and desiccated powders after vacuum filtration or rotary evaporation. Its chemical‑resistant walls make it suitable for holding acidic or basic solutions during short‑term storage, while the tight‑fitting cap prevents evaporation and contamination. In quality‑control labs, the jar serves as a convenient vessel for preparing reference standards, conducting stability tests, and housing calibration solutions. Educational institutions appreciate the clear, uncolored body for teaching proper sample handling techniques, as students can easily observe color changes or precipitate formation. The jar’s dimensions allow it to fit inside standard laboratory ovens set to temperatures up to 150 °C, making it ideal for controlled drying cycles. Additionally, the lightweight design enables technicians to transport multiple jars simultaneously during field sampling or multi‑site studies, ensuring consistent sample integrity across locations.
In addition to conventional drying tasks, the PLC‑03720 jar proves valuable for specialized protocols such as solid‑phase extraction (SPE) cartridge conditioning, where the jar can hold the required solvents and reagents in a sealed environment to prevent evaporation. Its chemical resistance ensures that aggressive eluents, including strong acids like hydrochloric acid or bases such as sodium hydroxide, do not degrade the container, preserving sample purity throughout the process. The jar’s capacity also accommodates the preparation of bulk calibration standards for analytical instruments, allowing technicians to mix large volumes of reference solutions with minimal risk of contamination. For field laboratories operating in remote locations, the jar’s lightweight construction and robust sealing mechanism enable secure transport of hazardous chemicals, meeting safety regulations for hazardous material handling. Moreover, the clear labeling surface supports the use of color‑coded caps or stickers, facilitating quick identification of contents in busy workspaces. When used in conjunction with a laboratory oven, the jar’s ability to tolerate temperatures up to 150 °C ensures that drying cycles can be performed efficiently without compromising the integrity of the cap or the polymer walls.
