Description
Product Overview
United Scientific delivers a laboratory‑grade container that combines durability, chemical resistance, and optical protection in a single, easy‑to‑use design. The 33465PK2 model is crafted from high‑density polyethylene (HDPE) that resists cracking, impact, and a wide range of solvents, making it suitable for both routine and demanding laboratory workflows. Each bottle holds 16 oz (500 ml) of liquid, providing ample capacity for sample storage, reagent preparation, and small‑scale production runs. The amber coloration is specifically engineered to block ultraviolet (UV) radiation, preserving the integrity of light‑sensitive compounds such as photosensitive reagents, vitamins, and certain pharmaceuticals. The wide‑mouth opening, measuring approximately 2.5 cm in diameter, simplifies pouring, filling, and cleaning, reducing the risk of cross‑contamination and allowing for quick visual inspection of contents. Integrated into the cap is a precision‑molded seal ring that creates a leak‑proof barrier, preventing accidental spills during transport or when the bottle is stored on a bench. The product dimensions—2.5 × 2.5 × 6.5 inches and a weight of 5.11 oz—make it compact enough to fit standard laboratory racks while still offering a generous volume. United Scientific’s commitment to quality is reflected in the product’s compliance with USP storage requirements, RoHS standards, and its BPA‑free, phthalate‑free composition, ensuring that the container does not leach harmful substances into its contents.
Usage
These amber HDPE bottles are designed for a broad spectrum of laboratory and industrial applications. In research laboratories, they are ideal for storing chromatography solvents, enzyme solutions, and cell culture media that degrade when exposed to light. Quality control labs benefit from the leak‑proof design when handling hazardous chemicals, as the secure seal minimizes the risk of exposure to personnel and the environment. In pharmaceutical manufacturing, the UV‑blocking amber glass alternative helps maintain drug potency during intermediate storage steps. The wide mouth facilitates the addition of powders, viscous liquids, and even solid samples, making the bottle a versatile choice for formulation work, sample preparation, and analytical testing. Field technicians who collect environmental samples appreciate the robust construction that can withstand transport in rugged conditions, while the clear labeling area on the bottle’s body allows for easy identification of contents. The containers are also compatible with standard laboratory equipment such as auto‑samplers, bottle racks, and dispensing stations, ensuring seamless integration into existing workflows. Whether used in a high‑throughput screening facility, a teaching laboratory, or a small‑scale biotech startup, the 33465PK2 provides reliable performance across diverse operational settings.

FAQ
What types of chemicals are safe to store in these amber HDPE bottles?
The bottles are compatible with most aqueous solutions, organic solvents, acids, and bases commonly used in laboratory settings. However, they should not be used with strong oxidizing agents such as concentrated hydrogen peroxide or peracids, as these can degrade HDPE over time.
Can the bottles be sterilized for microbiological applications?
Yes, the containers can be autoclaved at 121 °C for up to 30 minutes without compromising the integrity of the amber color or the leak‑proof seal. For applications requiring sterile conditions, we recommend sealing the bottle with a sterile cap after autoclaving.
How does the amber color affect UV protection compared to clear HDPE bottles?
Amber HDPE provides a significant reduction in UV transmission, typically blocking more than 95 % of UV‑B and UV‑C wavelengths. This level of protection is comparable to that of amber glass, making it suitable for preserving photosensitive compounds.
Are the caps compatible with standard laboratory dispensing equipment?
The caps feature a universal thread size (28‑410) that fits most laboratory bottle racks, auto‑samplers, and dispensing stations. The integrated seal ring ensures a tight fit, while the smooth exterior allows for easy gripping by automated systems.
What is the recommended storage temperature range for these bottles?
United Scientific amber HDPE bottles perform optimally between –20 °C and 60 °C. They can be stored in standard laboratory refrigerators or freezers without cracking, and they retain their structural integrity at typical ambient temperatures.
