AQUALAB Boosts
Sustainability & Safety
with Standards Switch

More environmentally friendly, better for customers

Potassium acetate offers significant advantages over lithium chloride, aligning with AQUALAB’s commitment to sustainability, safety, and quality.

Potassium acetate is much safer to handle, as it is non-toxic and classified as a non-hazardous material, making it a more environmentally and user-friendly alternative. Unlike lithium chloride, which must be mined, potassium acetate is manufactured. This ensures a more sustainable, consistent, and higher quality supply.
 

Raising the bar on quality

While all AQUALAB water activity standards are produced to the highest quality, ensuring access to ultra-pure lithium chloride, which is crucial for AQUALAB water activity standards, poses a significant challenge, as impurities can affect the efficacy.

Each potassium acetate water activity standard is supplied with a Certificate of Conformance (CoC) to ensure traceability, reliability, and consistency. AQUALAB potassium acetate standards perform to the same specifications as the current lithium chloride standards. 
 

Timeline

AQUALAB will continue producing lithium chloride-based 0.25 aw and 0.50 aw Water Activity Standards while utilizing our existing supplies. Once the current stock is depleted, we will transition to potassium acetate. The new water activity standards will be available as early as June 2025. 
 

Implications for current AQUALAB users

Potassium acetate is less sensitive to temperature than the lithium chloride counterparts. For instruments that are user calibrated at temperatures other than 25 °C, new firmware may be needed.
