Frequently Asked Questions (FAQ) About Our Bromothymol Blue
Q1: What is your Minimum Order Quantity (MOQ) for Bromothymol Blue?
A: Our standard MOQ is 10g. We cater to both large-scale industrial clients and smaller research facilities. For R&D, pilot projects, or sample evaluation, we are happy to accommodate smaller quantities. Please get in touch with us to discuss your specific needs.
Q2: Is the manufacturing facility for this product ISO certified?
A: Yes. Our Bromothymol blue is produced in a fully ISO-certified facility. This ensures the highest standards of quality control, documentation, and traceability from raw materials to finished product.
Q3: What is the lead time for bulk orders, and what packaging do you use?
A: Standard bulk orders are typically ready for shipment within 5-10 business days. We ship globally via reliable logistics partners. The product is packaged to ensure stability, using double polyethylene bags sealed inside vacuum-packed foil bags, placed in secure, light-resistant HDPE containers with desiccants.
Q4: What is the precise mechanism of action of Bromothymol Blue as a pH indicator?
A: Bromothymol Blue is a weak acid that exists in a dynamic equilibrium between its protonated (acidic) and deprotonated (basic) forms. The color change is due to a shift in this equilibrium and a corresponding change in the molecule’s light absorption spectrum:
At low pH (≤6.0), the solution is protonated and absorbs visible light, giving a yellow color.
At high pH (≥7.6), the solution is deprotonated, altering its molecular structure and shifting its absorption to different wavelengths, resulting in a blue color.
In between: A gradient of green colors is observed, representing a mixture of the two forms.
Q5: What are the shelf life and optimal storage conditions for this product?
A: Our bulk Bromothymol Blue has a shelf life of 24 months from the date of manufacture when stored correctly. To maintain its stability and performance, it must be stored in its original, tightly sealed container in a cool, dry, and well-ventilated place (below 25°C), protected from light and moisture.
Q6: Can we request a sample to verify quality and performance in our application?
A: Absolutely. We encourage all potential partners to test our product’s quality. We offer complimentary samples for qualified businesses (manufacturers, importers, licensed pharmacies) along with the corresponding COA. Please submit a sample request on our website, and our team will be in touch to process it.
