What is the difference between plastic and glass petri dishes?

Plastic (polystyrene) petri dishes like these are typically single-use and come pre-sterilized, making them convenient for routine microbiology work. Glass borosilicate dishes are reusable, can be autoclaved repeatedly, and withstand higher temperatures — suitable for labs that sterilize and reuse glassware.

Are these weighing dishes sterile and ready to use?

These Heathrow Scientific weighing dishes are manufactured and packaged in a clean room environment, ensuring high purity. While not explicitly stated as gamma-sterilized, they are suitable for general laboratory use where pre-sterilization is not a strict requirement for non-critical applications.

How to choose weighing dishes for Indian lab use?

Consider the sample type and volume. For weighing liquids and powders in general lab settings, these 259 mL polystyrene dishes with a pour spout are ideal. Ensure they are compatible with your chemicals and temperature requirements (up to 70°C).

What is the best use for Heathrow Scientific weighing dishes?

These dishes are best for weighing and mixing liquid and powder samples, especially when accurate pour-outs with minimal loss are needed. Their chemical resistance and FDA/food-grade compliance make them suitable for a wide range of laboratory and industrial applications.

Can I use these weighing dishes for high-temperature applications?

No, these polystyrene dishes have a temperature resistance limit of up to 70°C (158°F). They are not suitable for high-temperature autoclaving or applications exceeding this temperature.

How to buy original Heathrow Scientific weighing dishes in India?

Purchase from authorized US retailers and authorized brand partners like CrowCrowCrow. These dishes are factory-sealed, imported per-order, and all customs duties and GST are included in the price. Delivery is via ExpressBox tracked service.

Are these weighing dishes suitable for cell culture?

These dishes are designed for weighing and mixing, not specifically for sterile cell culture. For cell culture, look for dishes explicitly labeled as sterile and designed for that purpose, often with specific lid designs to control gas exchange.

What are the dimensions of the Heathrow Scientific weighing dishes?

Each dish measures approximately 108 mm in length, 183 mm in width, and 26 mm in depth, with a capacity of 259 mL.
