FAQ
What does nitrogen‑free mean and why is it important?
Nitrogen‑free indicates that the paper contains no residual nitrogen gases that could react with sensitive samples. This property is crucial for gravimetric analyses where oxidation or other chemical reactions would compromise accuracy.
Can the weighing paper be used with all types of balances?
Yes, the 3 x 3 inch dimensions are compatible with most analytical balances, microbalances, and standard laboratory scales. The paper’s thin profile ensures it does not interfere with balance calibration.
Is the pack of 500 sheets suitable for high‑throughput labs?
Absolutely. The large quantity reduces the frequency of reordering, supporting continuous operation in research, quality‑control, and teaching labs.
How should the weighing paper be stored to maintain its quality?
Store the sheets in a cool, dry place away from direct sunlight. Keep the original packaging sealed when not in use to protect against moisture and dust.
What is the return policy if the product does not meet expectations?
Thomas Scientific offers a straightforward return process within the standard return window. Contact our support team for assistance, and we will arrange a replacement or refund as appropriate.
