Yopay 4 Pack Glass Media Bottle 1000ml with GL45 Blue Screw Cap

Description

Product Overview

The Yopay 4 Pack Glass Media Bottle 1000ml is a thoughtfully engineered solution for scientists, educators, and hobbyists who require reliable, high‑quality liquid storage. Each bottle is constructed from premium borosilicate glass, a material renowned for its exceptional thermal resistance, chemical inertness, and long‑term durability. The clear, thick‑walled design not only resists breakage under typical laboratory conditions but also provides a pristine view of the contents, allowing for easy visual monitoring of reagents, cultures, or solutions.

Every bottle comes equipped with a GL45 blue screw cap that incorporates a precision‑molded O‑ring at the top of the glass. This design creates a leak‑proof seal that can withstand autoclaving at 284 °F (138 °C) without compromising the integrity of the cap or the bottle. The caps are linerless, eliminating the need for disposable liners and reducing waste while still delivering a secure closure. The caps are also compatible with standard laboratory equipment, making them easy to integrate into existing workflows.

Usage

These bottles are versatile enough to serve a wide range of applications. In academic laboratories, they are perfect for preparing media, storing stock solutions, and conducting small‑scale experiments where precise volume measurement is essential. In high‑school science classrooms, the graduated markings—spaced at every 100 ml from 100 ml to 900 ml—provide a clear visual guide for students learning basic titration, dilution, and mixing techniques. For home users and hobbyist chemists, the compact 9.3‑inch height and lightweight 5.16‑pound package make them easy to store on shelves or in cabinets while still offering the professional performance of laboratory‑grade glassware.

Because the bottles are made from borosilicate glass, they can be safely autoclaved, heated, or chilled without risk of cracking or deformation. This makes them ideal for protocols that require sterilization, such as microbiology media preparation or cell culture work. The leak‑proof caps also enable secure transport of hazardous or volatile liquids, ensuring that spills are minimized during movement between workstations or between the lab and field sites.

Why Choose Us

FAQ

Can these bottles be autoclaved?

Yes, both the borosilicate glass and the GL45 caps are rated for autoclaving up to 284 °F (138 °C). The caps should be tightened after the cooling cycle to avoid creating a vacuum seal that could make removal difficult.

What is the accuracy of the graduation lines?

The white graduation lines are calibrated at every 100 ml interval, providing a visual accuracy suitable for most laboratory and educational applications. For high‑precision work, a calibrated pipette or burette is recommended.

Are the caps compatible with other glassware?

The GL45 screw thread is a standard size used on many laboratory bottles and jars, making the caps interchangeable with other containers that share the same thread specification.

How should I clean the bottles after use?

Rinse the bottles with distilled water, then wash with a mild detergent if needed. For sterilization, place the bottles and caps in an autoclave. The caps can also be cleaned with high‑pressure steam without damaging the O‑ring.

What is the warranty on these bottles?

Yopay offers a one‑year limited warranty covering manufacturing defects in the glass and caps. If a defect is identified, contact our support team for a replacement or refund.

In summary, the Yopay 4 Pack Glass Media Bottle 1000ml set combines robust borosilicate construction, secure GL45 caps, and user‑friendly graduation markings to meet the demanding needs of modern laboratories, classrooms, and home science enthusiasts. Whether you are preparing culture media, measuring reagents, or conducting STEM projects, these bottles provide the reliability and precision required for successful outcomes.
