Assorted VWR PYREX KIMAX 500 ml Glass Storage Bottles with Pour Ring and Cap Total of 6 Bottles

Assorted 500 ml Borosilicate Glass Media Storage Bottles (VWR, Pyrex, Kimax) - Lot of 6

Engineered for the rigorous demands of reagent preparation and biological media storage, this assorted lot of six 500 ml glass bottles includes premium selections from trusted manufacturers such as VWR, Pyrex, and Kimax. Each vessel is constructed from chemically inert, Type I borosilicate glass, offering exceptional resistance to thermal shock and highly aggressive corrosive solvents. The bottles feature standard threaded necks equipped with durable, temperature-resistant polymer caps and integrated drip-free pour rings, ensuring a tight seal and clean fluid transfer. High-contrast, permanent enamel graduations and large marking spots are fired directly into the glass for precise volumetric approximations and durable sample identification. Fully autoclavable and endlessly reusable, these resilient storage bottles withstand repeated sterilization cycles without compromising their structural integrity. This mixed lot provides an excellent, cost-effective opportunity for analytical and clinical laboratories to expand their premium glassware inventory with industry-standard, high-performance vessels.

Technical Performance and Design

• Premium Borosilicate Glass: Formulated to withstand extreme temperature fluctuations and resist chemical leaching, ensuring that sensitive buffers and cell culture media remain uncompromised over time.

• Drip-Free Pour Rings: Integrated polymer rings strategically seated on the bottle neck cut off the liquid stream sharply, preventing hazardous chemicals or valuable reagents from running down the exterior glass during dispensing.

• Threaded Autoclavable Caps: Manufactured from high-temperature resistant polypropylene, providing a secure, leak-proof seal that reliably survives repeated high-pressure steam sterilization cycles without warping.

• Permanent Enamel Markings: Features bold, chemically resistant white graduations and marking areas that will not fade, chip, or wear off, even after extensive mechanical washing and exposure to harsh cleaning agents.

Key Benefits & Applications

• Biological Media Storage: The inert, autoclavable glass environment is perfect for safely preparing, sterilizing, and archiving complex agar formulations and liquid broths without the risk of biological contamination.

• Corrosive Chemical Handling: Provides a safe, non-reactive containment solution for aggressive acids, volatile organic solvents, and caustic bases that would rapidly degrade standard plastic storage vessels.

• Thermal Processing Resilience: Withstands the extreme thermal stress of hot plate heating, microwave boiling, and deep freeze archiving without shattering or developing dangerous micro-fractures.

• Cost-Effective Lab Expansion: Bundling high-quality, interoperable glassware from top-tier brands into a mixed lot allows budget-conscious laboratories to acquire premium storage solutions at a high-value price point.
