Microcrystalline cellulose is commercially available in different particle sizes and moisture grades which have different properties and applications.
Avicel PH 101
Has a nominal mean particle size of 50 microns
<=1% is retained on mesh size 60
<=30% is retained on mesh size 200
Avicel PH 102
Has a nominal mean particle size of 100 microns
<=8% is retained on mesh size 60
>=45% is retained on mesh size 200
Both have a moisture content of <=5%
Avicel pH 101 is microcrystalline cellulose used as a pharmaceutical excipient. Avicel pH 102 is a special grade of microcrystalline cellulose with improved flow properties. Avicel pH 103 is another grade of microcrystalline cellulose with enhanced binding properties.
Avicel PH-101 is a type of microcrystalline cellulose, which is a commonly used excipient in pharmaceutical formulations to improve the compressibility and flow properties of tablet granulations. It is widely used as a direct compression diluent in the manufacturing of tablets and is also used as a disintegrant to aid in the breakdown of tablets in the digestive tract.
"PH" designation indicates that the product is suitable for pharmaceutical use.
Avicel pH 102 is typically used as a pH buffer in pharmaceutical formulations. It is commonly used in the range of pH 5.5 to 7.5, but the exact pH can vary depending on the specific formulation and conditions.
100 and 363, 101 and 364, 102 and 365, ... Take your pick!
well, 102 is 1 less then 103, there different numbers
203
101/102 is in its simplest form.
99, 101
101-102 =0.1
102
101/102 cannot be simplified any further. 101 is a prime number.
