Why Source CALF-20 from Existent?
Existent is licensed to supply CALF-20 broadly: to any buyer, at any scale, for any qualifying application.* Sorbent provenance, quality, and supply continuity matter when establishing a carbon capture program.
• Full characterization with every order. Each batch ships with CO₂ isotherm data. Your modelling and process design teams get the data they need; no black-box material risk.
• Canadian manufacturing, gram to commercial scale.
• Published in top peer-reviewed journal, validated by 30+ independent studies. CALF-20 was first reported in Science (December 2021) by University of Calgary researchers. More than 40 follow-on peer-reviewed papers across independent groups have since confirmed its performance, stability, and scalability, making it the most validated solid physisorbent designed for post-combustion CO₂ capture available today.
• Technical engagement, not just a catalog listing. We respond to all inquiries within one business day and support customers through material selection, form factor decisions, and scale-up planning. OEM supply, licensing, and co-development discussions welcome.
Frequently Asked Questions (FAQ)
What is the price of CALF-20?
CALF-20 pricing depends on quantity, form factor, purity specification, and shipping destination. Reference pack sizes range from 1 g (laboratory screening) through 1 kg (engineering evaluation) and up to commercial bulk. Complete the inquiry form above or contact us directly for a quote tailored to your specific requirements. We provide transparent pricing with no hidden fees.
How is Existent CALF-20 different from other suppliers?
Several generic catalog suppliers list CALF-20 for sale with no characterization data and no provenance documentation including production under license. Our material is manufactured in Canada and each batch ships after passing our QC process, which includes confirming its CO2 isotherm data at 298 K. This matters for research validity and process modeling accuracy.
What CALF-20 form factors are available from Existent?
CALF-20 is available as powder (as-synthesized) and low-order forms like extrudates. Extrudates, pellets, granules, beads are suited to packed-bed adsorption columns and reduce pressure drop compared to loose powder. Contact us to discuss the right form factor for your system and scale.
Can I buy CALF-20 from Existent for academic or government-funded research?
Yes. We supply research quantities from 1 g upward and can issue purchase orders compatible with university procurement systems. We can also discuss material supply agreements for multi-year grant-funded programs.
What industries is CALF-20 used in?
CALF-20 is relevant to post-combustion carbon capture in natural gas power, cement, lime, refinery, petrochemical, and industrial heat applications. It is also used in biogas upgrading (CO2/CH4 separation in the presence of water). More than 30 peer-reviewed papers published since 2021 describe its use across these sectors.
What is the minimum order quantity?
Our minimum order is 1 gram for research purposes. Pilot and commercial quantities are available on request. There is no maximum order size, contact us for bulk and long-term supply discussions.
Does Existent ship internationally?
Yes. We ship to most countries. Shipping cost, lead time, and any applicable export documentation requirements depend on destination. Please include your country with your inquiry and we will confirm availability and shipping details.
Is CALF-20 safe to handle?
Powdered CALF-20 is a zinc-based crystalline powder. It should be handled with standard laboratory precautions — gloves, eye protection, and dust mask where fine powder handling is involved. A Safety Data Sheet (SDS) is available on request and ships with every order.
