Description

In cell culture, microbiology, and routine laboratory liquid preparation, larger-volume media and buffer storage often requires a sterile container that can protect solutions from contamination, leakage, breakage, and gas exchange during handling, refrigeration, and transport. Glass bottles provide clarity but are fragile, while ordinary plastic bottles may not offer the sterility, biological cleanliness, or gas-barrier performance required for sensitive laboratory workflows.

500 mL Sterile Laboratory Culture Medium Bottle is a clear square PET media bottle designed for storing, transporting, and aliquoting liquid media, buffers, sera, and biological solutions. Made from USP Class VI polyethylene terephthalate (PET), the bottle provides high transparency, lightweight handling, and shatter-resistant performance for daily laboratory use.

The 500 mL capacity is suitable for medium-volume storage of prepared culture media, sterile buffers, serum-containing media, and aqueous laboratory reagents. The square bottle body helps save refrigerator, cold-room, incubator, and shelf space, while molded graduations provide convenient volume reference during filling and dispensing.

Low CO₂ and O₂ permeability helps provide gas-barrier protection for culture media and pH-sensitive laboratory solutions. Each bottle is gamma sterilized and supplied sterile for ready-to-use workflows. The product is DNase-free, RNase-free, non-pyrogenic, and endotoxin-free, making it suitable for contamination-sensitive applications in cell culture, molecular biology, microbiology, and general reagent preparation. The HDPE screw cap supports secure closure for routine liquid storage and transport.

FAQ

What is a 500 mL sterile culture medium bottle used for?

It is used for storing, transporting, and aliquoting liquid culture media, buffers, sera, biological reagents, and aqueous laboratory solutions. The sterile PET bottle is suitable for cell culture, microbiology, molecular biology, and general laboratory workflows.

Is this bottle made from PET or PETG?

This product uses USP Class VI PET material. PET provides high clarity, lightweight handling, break resistance, and low gas permeability, making it suitable for laboratory media, buffer, and serum storage.

Is the 500 mL culture medium bottle sterile?

Yes. The bottle is gamma sterilized and supplied sterile for ready-to-use laboratory applications. It is also DNase-free, RNase-free, non-pyrogenic, and endotoxin-free.

Why is low CO₂ and O₂ permeability important for media storage?

Low CO₂ and O₂ permeability helps reduce gas exchange through the bottle wall. This is useful for culture media, buffers, sera, and pH-sensitive liquids where storage stability is important.

Can this bottle be used for cell culture media?

Yes. The sterile culture medium bottle is suitable for storing and aliquoting cell culture media, prepared media, serum-containing media, and related biological solutions when the bottle material is compatible with the specific formulation.

Can this bottle replace a glass media bottle?

In many storage and transport workflows, yes. The clear PET bottle is lightweight, transparent, and shatter-resistant, making it a practical disposable alternative to glass media bottles. Users should confirm chemical compatibility and temperature requirements for their specific solution.

What are the benefits of the square media bottle design?

The square bottle body improves grip and helps conserve space in refrigerators, cold rooms, incubators, and storage shelves. It also supports more efficient packing and transport compared with many round bottle formats.

Does the bottle have graduations?

Yes. The bottle body includes molded graduations that provide a convenient volume reference during filling, aliquoting, and routine liquid handling.

Is the cap leak-resistant?

The bottle is supplied with an HDPE screw cap designed to provide secure closure for routine storage and transport. Proper tightening and validation under the user’s own transport conditions are recommended.

What types of solutions can be stored in this bottle?

The bottle is commonly used for culture media, buffers, sera, biological reagents, and aqueous laboratory solutions. Chemical compatibility should be checked before use with solvents, strong acids, strong bases, or specialty formulations.
