Qorpak PLC-03729 Clear Polystyrene Jar with 89-400 White Polypropylene SturdeeSeal Polyethylene Foam Lined Cap Attached, 16 oz (Pack of 24)

Description

Product Overview

The Qorpak PLC-03729 clear polystyrene jar is engineered for laboratory environments where precision, durability, and clarity are essential. Constructed from high‑grade polystyrene, the jar offers glass‑like transparency while remaining lightweight and impact‑resistant. Each jar holds 16 oz (approximately 473 ml) of material, a size that balances sufficient volume for bulk reagents with the convenience of easy handling. The wide‑neck opening, paired with straight sides, enables effortless pouring, sampling, and cleaning, reducing the risk of spillage or residue buildup. The SturdeeSeal cap, fabricated from white polypropylene, features a secure snap‑fit design that locks the lid in place, while the integrated polyethylene foam liner creates a protective barrier against moisture ingress and external contaminants. This dual‑seal system ensures that volatile or hygroscopic samples remain stable over extended storage periods.

The jar’s exterior surface is treated to be slip‑resistant, providing a secure grip even when gloves are worn. Its clear body allows users to quickly assess the quantity and condition of the contents without opening the container, a critical advantage in high‑throughput settings. All components are manufactured in the United States, adhering to strict quality‑control standards that guarantee consistency across each of the 24 units in a pack. The product is certified to meet laboratory safety regulations, making it suitable for a wide range of applications, from chemical storage to specimen preservation.

Usage

These jars excel in diverse laboratory scenarios. In analytical chemistry labs, they serve as primary containers for solvents, reagents, and standards, where the clear visibility helps technicians monitor levels and detect any precipitation or discoloration. In microbiology, the jars are ideal for storing culture media, agar plates, and dried bacterial isolates, as the airtight SturdeeSeal cap prevents desiccation and contamination. The foam‑lined interior is particularly beneficial for hygroscopic compounds such as salts, acids, and enzymes, preserving their potency by minimizing moisture exposure.

In quality‑control facilities, the jars are frequently used to hold reference materials that require strict environmental control. Their robust construction withstands routine transport between workstations, and the slip‑resistant exterior reduces the chance of accidental drops. The 24‑unit packaging simplifies inventory management, allowing labs to maintain a ready supply of uniform containers without the need for individual ordering. Additionally, the jars are compatible with standard laboratory equipment, such as autoclave racks and centrifuge rotors, ensuring seamless integration into existing workflows.

Why Choose Us

Choosing the Qorpak PLC-03729 jar means selecting a product backed by Thomas Scientific’s reputation for scientific excellence. Each jar undergoes rigorous testing for impact resistance, chemical compatibility, and seal integrity, guaranteeing that the container performs reliably under demanding conditions. The combination of a high‑clarity polystyrene body and a dual‑seal system provides a level of protection that surpasses many competing products, which often rely on a single sealing mechanism.

Our manufacturing process incorporates precision molding techniques that produce uniform wall thickness, reducing the likelihood of stress cracks and ensuring consistent performance across the entire batch. The foam liner is precisely cut to fit the cap interior, creating a seamless seal that mitigates the risk of leaks. Moreover, the jars are supplied in a compact, stackable configuration that optimizes storage space in both laboratory cabinets and bulk shipping containers.

Customer support is a cornerstone of our service model. Our technical team is available to assist with product selection, troubleshooting, and compliance documentation. Should any issue arise, we offer a responsive warranty program that addresses defects promptly, reinforcing our commitment to long‑term customer satisfaction.

FAQ

Can the jar be autoclaved for sterilization?

Yes, the polystyrene body and polypropylene cap are both rated for standard autoclave cycles up to 121 °C (250 °F). The foam liner is designed to withstand repeated sterilization without degrading, making the jar suitable for reusable applications where sterility is required.

Is the jar compatible with chemical solvents?

The jar is compatible with a broad range of laboratory solvents, including water, ethanol, methanol, and many buffered solutions. For highly aggressive acids or bases, we recommend verifying compatibility with the specific chemical to ensure long‑term durability.

What is the recommended storage temperature range?

The container performs optimally between -20 °C and 60 °C (-4 °F to 140 °F). This range covers most laboratory storage conditions, from refrigerated reagents to ambient‑temperature samples.

How does the foam liner improve sample integrity?

The polyethylene foam liner creates a secondary seal that reduces the exchange of air and moisture between the interior of the jar and the external environment. This helps maintain the stability of hygroscopic or volatile substances, extending their shelf life and preserving analytical accuracy.

Can the jar be used for solid samples as well as liquids?

Absolutely. The wide opening and smooth interior surface make the jar suitable for both liquid reagents and solid powders, crystals, or dried specimens. The clear body allows easy visual inspection of solid contents without opening the container.
