CALF-20 Zinc-Based Metal-Organic Framework PowderRESEARCH GRADE MATERIAL

||||||||||||||||||||||
|
CALF-20 zinc-based metal-organic framework powder requires strict anhydrous inert gas handling and thermal activation to maintain structural integrity. The material degrades upon exposure to ambient air before a 12-hour vacuum activation at 120°C.
- Storage Conditions: Store CALF-20 powder under strictly dry and tightly sealed containment to preserve its initial quality.
- Atmospheric Handling: Handle the powder exclusively within an anhydrous inert gas environment to prevent phase contamination or degradation before thermal validation.
- Thermal Activation: Activate the powder under vacuum at 120°C for 12 hours prior to testing workflows.
- Ambient Sensitivity: The material is highly sensitive to ambient exposure and requires inert gas handling until thermal activation is complete.
- Pre-activation Handling: Keep containers tightly sealed and avoid exposure to air or moisture before the activation step.
What is the required thermal activation protocol for CALF-20 before gas adsorption testing?
CALF-20 requires thermal activation under vacuum at 120°C for a continuous 12-hour duration to achieve optimal framework performance validation and remove pre-adsorbed species from the micro-cavities before testing workflows.
How does the narrow pore size range of CALF-20 affect gas selectivity compared to broader-pore MOFs?
The pore size range of 0.19–0.3 nm enables CALF-20 to provide high geometric selectivity for targeted small gas molecules due to its ultra-fine micro-cavity structuring, which restricts access by larger molecular species and ensures uniform distribution within the 0.5 cm³/g pore volume.
Can CALF-20 maintain structural integrity in aqueous slurries during sample preparation?
Yes, CALF-20 exhibits exceptional framework preservation within water-based environments, preventing structural phase breakdown during testing slurry workflows, based on its aqueous solution tolerance and long-term stability in ambient air as specified in the product description.
CALF-20 is a zinc-based MOF with exceptional ambient and aqueous stability, narrow pore size (0.19–0.3 nm) for selective gas adsorption, but requires thermal activation (120°C, 12 h vacuum) and strict inert handling to prevent degradation.
Positive
- Persistent Environmental Stability: Engineered matrix provides excellent long-term resistance to ambient air and remains highly stable in aqueous solutions, enabling reliable performance in slurry workflows and routine lab conditions.
- Narrow Micro-Cavity Structuring: Ultra-fine pore network (0.19–0.3 nm) combined with high BET surface area (>200 m²/g) and pore volume (0.5 cm³/g) delivers high geometric selectivity for targeted small gas molecules in adsorption and separation testing.
Trade-offs
- Thermal Activation Required: Optimal framework performance requires vacuum thermal activation at 120°C for 12 hours prior to testing, adding a mandatory pre-processing step that may delay workflows.
- Sensitive to Ambient Exposure: Product is highly sensitive to ambient moisture and air; containers must be kept sealed or handled in anhydrous inert gas environments to prevent phase contamination or degradation before activation.
