Premium Macadamia Shell
Granulated Activated Carbon (GAC)
12-40 Mesh (0.4-1.68mm)
1L Autoclavable Tub

Premium Multi-Purpose Adsorption Media

Experience the exceptional surface science of high-purity Granular Activated Carbon (GAC) derived from dense macadamia nut shells. Unlike standard charcoal or softer carbon media, macadamia shell GAC features an advanced dual-pore cellular matrix. This structural lattice provides a massive surface area optimized specifically for targeted liquid and gas-phase adsorption.

Sifted strictly to a 12-40 mesh specification (0.425 to 1.68 mm), this structural media allows for maximum fluid dynamics, prevents structural compaction, and eliminates restrictive anaerobic pooling. Whether utilized for rigorous laboratory water purification, environmental odour/toxin filtration, premium terrarium design, or biological soil amendment charging, it delivers world-class structural stability.

Conveniently packaged in a premium, reusable 1L autoclavable polypropylene screw-cap tub for ultimate storage integrity and moisture prevention.

Features

• Pre-Packed in 1L Autoclavable PP Tubs: Shipped ready-to-use or re-sterilize directly inside a heavy-duty, reusable lab-grade container.

• Dual-Pore Matrix Architecture: Optimized micro- and mesoporous network (2 to 50 nm) designed to lock in organic carbohydrate primers.

• High Physical Integrity & Low Dust: Strictly sifted to a uniform 12-40 mesh (0.425 to 1.68 mm) profile, resisting fracturing and breakdown into fine dust.

• Multi-Purpose Functionality: Engineered for high-efficiency water filtration, air/odour purification, soil amendment charging, and advanced Terra Preta applications.

12×40 Mesh

A 12×40 mesh refers to the particle size classification for granular materials, most commonly Granular Activated Carbon (GAC) used for water and air purification. It means all granules can pass through a 12-mesh sieve, but are caught by a 40-mesh sieve, resulting in a particle size of about 0.425 to 1.68 mm. This eliminates all the fines.
