Why Choose Reusable PP5 Petri Dishes?

• Sustainability at Its Core: Reduce single-use plastic waste and support eco-friendly practices.
• Cost-Effective for the Long Term: Save money by eliminating frequent reordering of disposable dishes.
• Convenient Cleaning: Polypropylene dishes are top-shelf dishwasher safe, making cleaning a breeze.
• Durability and Versatility: Built from heat-resistant PP5 plastic, these dishes are perfect for autoclaving and pressure cooking.

How to Use Your Polypropylene Petri Dishes

1. Prepare the Agar: Mix and sterilize your agar medium as usual.
2. Pour and Settle: Carefully pour the liquid agar into the dishes in a sterile environment. Allow it to solidify.
3. Inoculate: Once ready, proceed with your inoculation or experiment.

Cleaning and Re-Sterilizing PP5 Petri Dishes

Step 1: Initial Cleaning

Rinse dishes immediately after use to remove debris. Wash with warm water and mild detergent, avoiding abrasive materials.

Step 2: Sterilization

Use one of the following methods:

• Autoclaving: Sterilize at 121°C for 15–20 minutes. Stack dishes loosely for optimal steam penetration in an autoclavable bag or unicorn bag. 
• Pressure Cooker: If no autoclave is available, a pressure cooker works effectively. Ensure dishes are exposed to steam, not submerged. Wrap loosely in an autoclavable bag or unicorn bag. 

Step 3: Storage in Sterile Bags

Place sterilized dishes in a Unicorn bag or loosely wrapped autoclave-safe bag before sterilizing. This ensures sterility until use. Store in sealed bags to protect them from contaminants.

Benefits of Switching to Reusables

Making the switch to reusable polypropylene petri dishes has numerous advantages:

• Environmental Impact: Reduce plastic waste and align with sustainability goals.
• Convenience and Reliability: Always have a dependable supply of petri dishes on hand.
• Educational Value: Learn and teach responsible lab practices while minimizing your environmental footprint.

Tips for Maximizing the Lifespan of Your Reusable Agar Plates

• Inspect Regularly: Check for cracks or warping after sterilization.
• Handle with Care: Avoid dropping or exposing to harsh chemicals.
• Use Sterile Techniques: Minimize contamination during use to reduce cleaning effort.
