  • Produced in a Class 100,000 cleanroom, it is DNA/RNAase-free, pyrogen-free, and endotoxin-free.
  • Meets diverse storage and packaging needs, compatible with standard pipettes, dispensing pumps, and filling systems.

FAQ Of Square Media Bottle

What Are The Advantages Of PETG Square Media Bottles​?

PETG bottles are widely used in cell culture, reagent storage, and laboratory liquid packaging due to their excellent transparency, chemical stability, and biocompatibility. Their main advantages include:

  • High Transparency
    PETG bottles provide excellent optical clarity, allowing easy observation of liquid conditions, sediment, and liquid levels during laboratory work.
  • Excellent Chemical Stability
    PETG material is resistant to culture media, buffers, acidic and alkaline solutions, and most laboratory reagents, helping maintain sample stability without chemical interaction.
  • Strong Mechanical Performance
    PETG offers high toughness and impact resistance, making the bottles less likely to crack or break during transportation and daily use, thereby reducing sample loss risks.
  • Good Biocompatibility
    PETG material has low cytotoxicity and is suitable for cell culture, serum storage, media storage, and other biological applications.
  • Compatible with Multiple Sterilization Methods
    PETG bottles can be sterilized using common methods such as gamma irradiation and ethylene oxide sterilization, meeting sterile laboratory requirements.
  • Lightweight and Easy to Transport
    Compared with glass bottles, PETG bottles are lighter in weight, easier to transport, and less prone to breakage.

In terms of material selection, PET media bottles are economical, practical, and highly transparent, making it suitable for the preparation and storage of daily culture media, sera, or buffers. However, it is relatively brittle and, if frequently handled or used in cold chain transportation, its impact resistance is inferior to that of PETG media bottles. PETG, a modified copolyester, offers greater toughness and is less prone to cracking even in low-temperature environments. It is particularly suitable for storing high-value reagents or for applications requiring repeated handling and transportation. If the laboratory environment is stable and not sensitive to shock, PET is sufficient. However, if transportation, refrigeration, or higher security requirements are required, PETG is a better choice.

In terms of volume selection, 125ml square media bottle and 250 ml media bottle are suitable for small-scale packaging or temporary use of reagents, facilitating quick access and avoiding waste; 500ml media bottle is the main specification for routine production and scientific research, balancing ease of use and storage capacity; 1000ml square media bottle or larger capacity is suitable for large-scale preparation or cell factory environments, which can reduce the number of packaging times but have higher requirements for aseptic operation and refrigerated storage space.

1. Confirm that the bottle is compatible with the reagent.

  • Choose PET or PETG based on the intended use: PET is suitable for general preparations, while PETG offers excellent toughness and is suitable for cold chain transportation or storage of high-value reagents.
  • Select an appropriate volume (125 mL, 250 mL, 500 mL, 1000 mL, etc.) based on the intended use to avoid frequent bottle openings or excessive leftovers.

2. Sterile Aliquoting or Adding Reagents

  • Work in a cleanroom, wearing sterile gloves and disinfecting thoroughly.
  • Use a serological pipette or an electronic pipette to aseptically transfer the culture medium or serum into a square bottle.
  • If using homemade culture medium, sterilize it by filtering it with a vacuum filter or bottle-top filter before filling the square bottle and immediately tightening the cap.

3. Labeling and Storage

  • Clearly label the plastic media bottles with the medium type, concentration, preparation date, and batch number.
  • Store in a refrigerator (2–8°C) or freezer (–20°C) as needed to avoid frequent freeze-thaw cycles.
  • Use foam racks or a compartmentalized cooler to minimize impact damage during transport, especially for square PET media bottles.
