Waters Corporation Porapak Porous Packing, Type S, 50-80 Mesh
Waters Porapak porous packings offer significant advantages in gas chromatography, featuring partition properties similar to a highly extended liquid surface. They eliminate common issues associated with support, polarity, liquid-phase volatility, or freezing point that often restrict gas/liquid chromatography. This design ensures sharp, symmetrical peaks and low retention volumes for substances including water, alcohols, and glycols.
- No bleed from the packing material
- No adsorption of polar compounds
- High temperature stability
- Consistent retention time
- Easy column packing with high efficiency
- Rapid overload recovery
- Porous polymer beads modified for varied retention characteristics
- Adjustable water peak position in chromatograms

Waters Corp Waters Bulk Media, Porapak P, 50-80 Mesh, 20 g
Porapak P is a porous polymer bead packing material for gas chromatography, offering advantages over traditional materials. It provides an extended liquid surface, preventing issues with support, polarity, volatility, or freezing. This yields sharp, symmetrical peaks and low retention volumes for compounds like water, alcohols, and glycols.
- Porous polymer bead construction.
- Low polarity.
- High surface area (100 to 200 m2/g) and density (0.27 g/cm3).
- Maximum temperature stability up to 250°C in oxygen-free atmosphere.
- Prevents bleed and adsorption of polar compounds.
- Ensures consistent retention times and delivers sharp, symmetrical peaks.
- Allows easy, efficient column packing and rapid overload recovery.
- Low retention volumes for water, alcohols, and glycols.

Gold Biotechnology Inc Digitonin Special Grade (water soluble) 1 g
Digitonin is a nonionic saponin steroid derived from the plant Digitalis purpurea. It is useful for creating Digitonin-cholesterol complexes which form when Digitonin disrupts the cell membrane and binds with cholesterol in a nearly 1:1 stoichiometric ratio. When precipitated from ethanolic solutions, these complexes form flat lamellar sheets. Digitonin’s cholesterol displacing properties have been used in newer applications to quantify the rate of lysosomal membrane permeabilization (LMP), a new technique developed to bypass traditional cell death pathways. Digitonin permeabilizes plasma membranes but leaves lysosomal membranes intact, allowing for a quantifiable measurement of lysosomal hydrolases and comparison to normal cellular enzyme activity. Digitonin has been shown to induce hemolysis in red blood cells
