Product Overview
The Whatman 3 PIECE PP PLT 9.0CM is a premium polypropylene petri dish designed for precise and contamination-free laboratory applications. Each dish features a three-piece construction with a vented lid to ensure proper airflow while maintaining sterility, making it ideal for critical microbiological and cell culture work. The dishes are gamma-irradiated to eliminate microbial contamination, providing a ready-to-use solution for sensitive experiments. The 9.0cm diameter offers ample surface area for sample distribution, while the clear polypropylene material allows for easy visualization of growth without compromising structural integrity. The dishes are compatible with standard incubation protocols and resist warping under autoclave conditions, ensuring consistent performance. Their disposable nature eliminates the risk of cross-contamination between experiments, while the stackable design optimizes storage space in busy lab environments. The vented lid design prevents condensation buildup, which could otherwise interfere with sample integrity. These dishes meet international laboratory standards for single-use plasticware, offering researchers a reliable and cost-effective solution for routine culturing applications.
FAQs
1. Are these Whatman PP petri dishes autoclavable?
The dishes are gamma-irradiated and sterile upon delivery, but they can withstand standard autoclave cycles at 121°C for 15-20 minutes if re-sterilization is required. However, repeated autoclaving may affect the vented lid’s performance over time.
2. What is the difference between vented and non-vented petri dishes?
Vented petri dishes like these Whatman models have small ridges or gaps in the lid that allow controlled gas exchange while preventing contamination. This design reduces condensation buildup and is particularly useful for aerobic microbial cultures or applications requiring consistent airflow.
3. Can these dishes be used for plant tissue culture?
While primarily designed for microbiological applications, these PP petri dishes can be used for plant tissue culture as the polypropylene material is chemically inert. However, for long-term plant tissue culture, consider dishes with deeper wells or those specifically designed for plant work to accommodate root growth.
4. How should these petri dishes be stored before use?
Store the unopened packs in a cool, dry place away from direct sunlight and chemical fumes. The original packaging is designed to maintain sterility until use. Once opened, use the dishes promptly or store them in a clean, dust-free environment with the lids properly sealed.
5. What alternatives are available if I need larger petri dishes?
For applications requiring larger surface areas, consider Whatman’s 10cm or 15cm diameter petri dishes, which maintain the same polypropylene construction and vented lid design. These larger sizes are particularly useful for experiments requiring more sample volume or when working with larger colonies.
