Method
Diluting Concentrated Stocks: C1V1 = C2V2 and Serial Dilutions
To dilute concentrated stocks accurately, use the formula C1V1 = C2V2, where C1 and V1 are the initial concentration and volume, and C2 and V2 are the final concentration and volume. For serial dilutions, apply the formula iteratively across multiple steps, ensuring consistent dilution factors. Precision depends on calibrated equipment and correct technique.
Method
Calculating Molarity: Mass, Molecular Weight, Volume and Common Pitfalls
Molarity (mol/L) is calculated using mass (g), molecular weight (g/mol), and volume (L). The formula is M = (mass / MW) / volume. Common errors include incorrect unit conversion, ignoring solute hydration, and inaccurate volume measurement. Always verify units and use calibrated equipment.

Understanding HTS and Tariff Codes for Chemical Imports: A Guide for UK and EU-Based Researchers
Customs Harmonised Tariff Schedule (HTS) codes are essential for classifying chemical imports under UK and EU trade regulations. Accurate HTS codes ensure compliance with REACH, TSCA, and GHS, and prevent delays or penalties. Codes vary by chemical structure, purity, and intended use. Always verify with national customs authorities or a qualified customs broker.
Regulatory
IATA/ADR Transport Classifications for Laboratory Chemicals
Laboratory chemicals are subject to IATA (air) and ADR (road) regulations based on hazard classification. Key categories include flammable liquids (Class 3), corrosives (Class 8), and toxic substances (Class 6.1). Proper classification requires evaluation of flash point, toxicity (LD50), and reactivity. Labels, packaging, and documentation must comply with UN recommendations and regulatory standards.

Customer story
"Molekula doesn't just supply chemicals — they operate as a supply partner."
A U.S. biotech procurement team switched from another supplier after years of unpredictable lead times. After moving to Molekula, they consolidated a significant portion of their purchasing — citing fast quotes, complete documentation, reliable deliveries, and ability to source non-catalog materials.
We moved to Molekula after a recommendation and the difference was immediate. Their team took the time to understand exactly what we were using the products for, confirmed specifications upfront, and offered equivalent or better-quality materials at more competitive pricing.
