Feature Of Borosilicate Glass Petri Dish

  • Made from premium borosilicate glass with high transparency and excellent optical clarity for easy observation of colonies, biological samples, and culture media.
  • Outstanding chemical resistance, tolerant to acids, alkalis, and common organic solvents without reacting with reagents.
  • Low thermal expansion coefficient enables repeated sterilization at 121 °C in autoclave conditions without deformation or cracking.
  • Equipped with a well-fitting lid to significantly reduce evaporation, minimizing medium loss and contamination risk.
  • Withstands temperatures up to ~300 °C and rapid thermal changes (instant temperature difference ≤ 170 °C).
  • Uniform wall thickness and a smooth, bubble-free surface ensure consistent and reliable culture conditions.
  • Stable, wide, and flat base allows secure stacking and convenient storage.

  • Widely used in microbiology, drug screening and toxicity testing, plant tissue culture, protein purification, and other laboratory applications.

FAQ Of borosilicate glass petri dishes

Glass vs. Plastic Petri Dish: What’s the difference?

Glass petri dishes are reusable, autoclavable, and highly resistant to heat and chemicals, making them ideal for repeated sterilization and long-term laboratory use. Plastic petri dishes are typically disposable, pre-sterilized, lightweight, and convenient for single-use microbiological or cell culture applications where contamination control is critical.

Before autoclaving, wash and dry the glass petri dishes thoroughly. Wrap them in sterilization paper or aluminum foil, then autoclave at 121 °C for 15–20 minutes under standard pressure. Allow the dishes to cool naturally inside the autoclave to prevent thermal shock or cracking.

Remove residual media or biological material immediately after use. Soak dishes in warm water with laboratory detergent, gently scrub if necessary, rinse thoroughly with distilled water, and dry before sterilization. For stubborn residues, enzymatic cleaners or mild alkaline solutions may be used.

Standard glass petri dishes are mainly used for microbiology. For adherent cell culture, surface-treated plastic culture dishes are generally preferred because they enhance cell attachment and growth.

Store sterilized glass petri dish with cover in a dry, dust-free, and sealed environment, preferably wrapped or placed in sterilization containers. Avoid stacking too tightly to prevent breakage.

  • The maximum instantaneous temperature difference should not exceed 170 °C to prevent cracking caused by thermal shock.
  • Do not fill liquid beyond two-thirds of the container volume to avoid overflow or expansion risks during heating.
  • Glassware is suitable for negative pressure conditions but not for positive pressure, which may cause damage or rupture.

  • When heating over an open flame, use a wire gauze or heating pad to ensure even heat distribution and reduce the risk of breakage.

  • Inspect the petri dish glass: Ensure the petri dish is intact, clean, and dry.
  • Prepare the workspace: Maintain a clean and sterile environment and prepare the required culture medium, cells, or microbial samples.
  • Sterilization: Autoclave the petri dish borosilicate glass, or use a suitable high-pressure steam sterilizer to sterilize them.
  • Add culture medium: Pour an appropriate amount of sterile culture medium into the dish and allow it to cool to room temperature.
  • Inoculate samples: Introduce cells or microbial samples onto the medium, following strict aseptic techniques.
  • Set culture conditions: Place the inoculated glass petri dish with lid in an incubator and set appropriate temperature, humidity, and lighting conditions.
  • Observe and record: Monitor sample growth regularly and record experimental data while maintaining aseptic handling.

  • Harvest and process: Once the samples meet experimental requirements, harvest or process them promptly under sterile conditions.
