Yopay 10 Pack Media Storage Bottles 250ml with Blue Screw Cap

Description

Product Overview

The Yopay 10 Pack Media Storage Bottles are engineered for scientific accuracy and everyday practicality. Each bottle is crafted from high‑quality borosilicate glass, a material renowned for its resistance to thermal shock, chemical corrosion, and mechanical impact. The 250 ml capacity strikes a balance between portability and sufficient volume for most laboratory and educational applications. A GL45‑size blue screw cap, equipped with an integrated O‑ring, provides a leak‑proof seal that can withstand autoclave temperatures up to 284 °F (140 °C). The caps are linerless, eliminating the need for disposable liners and reducing waste. Graduated markings are etched in white ink at 50 ml intervals, extending from 50 ml to 200 ml, allowing users to measure liquids with confidence and repeatability. The wide, flat labeling area on each bottle accommodates custom stickers, barcodes, or handwritten notes, making inventory management straightforward.

Usage

These bottles excel in a variety of environments. In research laboratories, they serve as reliable containers for media preparation, reagent storage, and sample aliquoting. Their clear glass body enables quick visual assessment of liquid levels, while the precise graduation lines reduce the need for secondary measuring devices. In educational settings, teachers can use them for hands‑on STEM activities, demonstrating concepts such as solution preparation, dilution series, and chemical reactions. The lightweight yet durable construction makes them easy for students to handle safely. Home hobbyists engaged in small‑scale fermentation, hydroponics, or DIY chemistry will appreciate the professional‑grade performance without the high cost of bulk lab glassware. Because the caps can be sterilized, the bottles are suitable for repeated use, supporting sustainable laboratory practices.

Why Choose Us

Yopay has a long history of supplying scientific glassware that meets rigorous quality standards. Each bottle undergoes a multi‑stage inspection process, including visual inspection for scratches, dimensional verification for uniform wall thickness, and pressure testing of the caps to confirm a consistent seal. The borosilicate composition is sourced from certified manufacturers, ensuring that every bottle can tolerate rapid temperature changes without cracking. Our GL45 caps are designed with a precision‑machined O‑ring that maintains its elasticity after repeated autoclave cycles, preventing leaks that could compromise experiments. In addition, Yopay offers responsive customer support: any concerns about product performance are addressed within 24 hours, and replacement parts are available for defective caps. This commitment to durability, reliability, and service makes Yopay the trusted choice for laboratories, schools, and serious hobbyists alike.

FAQ

Can the caps be autoclaved?

Yes, the GL45 caps are designed to tolerate autoclave temperatures up to 284 °F (140 °C). After the cycle, allow the bottle to cool slowly before tightening the cap to avoid creating a vacuum seal that could be difficult to open.

Are the graduation lines permanent?

The graduation markings are etched directly onto the glass surface with a high‑precision laser, making them resistant to fading, scratching, or chemical erosion.

What is the maximum pressure the bottle can withstand?

While the bottle is primarily intended for liquid storage at atmospheric pressure, the borosilicate construction can safely handle pressures up to 2 atm without deformation.

Is the blue cap color-coded for any specific purpose?

The blue cap provides a visual cue that distinguishes these bottles from standard clear‑cap containers, helping users quickly identify the product in a busy lab or classroom environment.

Can I use these bottles for corrosive chemicals?

Borosilicate glass offers excellent resistance to most acids and bases commonly used in laboratories. However, for extremely aggressive reagents such as hydrofluoric acid, consult the chemical compatibility chart before use.
