What are Heathrow Scientific weighing dishes made of?

These weighing dishes are made from 12mil thick polystyrene, a durable and biologically inert plastic. This material provides strength, stability, and resistance to dilute acids, aqueous solutions, alcohols, and bases, making them suitable for a wide range of laboratory applications.

Are these weighing dishes sterile and ready to use?

Yes, the Heathrow Scientific weighing dishes are manufactured and packaged in a clean room, ensuring a high level of purity and suitability for immediate use in most laboratory settings without requiring further sterilization.

What is the temperature resistance of these dishes?

These polystyrene weighing dishes can withstand temperatures up to 70°C (158°F). They are suitable for use with microwave moisture analyzers but should not be exposed to higher temperatures or used for autoclaving.

How do these dishes help with sample dispensing?

The unique pour-spout design on these weighing dishes allows for easy and controlled dispensing of samples. This feature minimizes sample loss and ensures accurate transfer, which is critical for precise laboratory measurements and analyses.

Can I use these dishes with acids or bases?

Yes, these dishes are biologically inert and resistant to dilute and weak acids, aqueous solutions, alcohols, and bases. This chemical resistance makes them a reliable choice for various laboratory procedures involving common lab chemicals.

Why choose this product

Precision and Purity for Indian Labs

Heathrow Scientific weighing dishes are engineered for accuracy. Their 12mil thick polystyrene construction offers superior strength and stability, preventing flexing during sample transfer. The biologically inert material resists common lab chemicals, ensuring sample purity. Manufactured in a clean room, these dishes minimize contamination risks, crucial for reproducible results in Indian research and quality control settings. Imported directly, they bypass grey-market uncertainties, guaranteeing authentic product quality for your critical applications.

Who Should Use These vs. Who Should Consider Alternatives

These dishes are ideal for general laboratory weighing, sample dispensing, and use with microwave moisture analyzers. They suit environments requiring chemical resistance to weak acids, bases, and alcohols. Consider alternatives if your work involves high temperatures above 70°C (158°F) or requires reusable, autoclavable glassware like borosilicate dishes. For extremely corrosive substances, specialized materials may be necessary.

How to use

Prepare for Weighing — Ensure dishes are clean and dry. If using non-sterile dishes, sterilize them according to your laboratory's protocol before use. For these cleanroom-manufactured dishes, proceed directly to sample handling.
Dispense Sample — Carefully place the sample into the weighing dish. Utilize the integrated pour spout for controlled transfer of the sample to or from the dish, minimizing spillage and ensuring accurate measurements.
Perform Analysis — Use the dish for weighing or place it in compatible equipment, such as a microwave moisture analyzer. The dish's material is resistant to weak acids, bases, and aqueous solutions up to 70°C.
Dispose or Clean — These dishes are disposable. After use, dispose of them according to your laboratory's waste disposal guidelines. For reusable dishes (not applicable here), clean and sterilize thoroughly.
