How to Find a Lot/Batch Number for COA
Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.
For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.
In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
The lot specific COA document can be found by entering the lot number above under the "Documents" section.
Although we do not measure molecular weight on a batch to batch basis, we would expect it to be approximately 310,000 to >375,000 based on the viscosity range of 800-2000 mPaS.
The particle size has not been determined. It is described as being course ground flakes or powder.
Chitosan is insoluble in water or organic solvents. Hazy suspensions can be prepared in 1M acetic acid at a concentration of 10 mg/mL, but extensive sonication may be required to fully suspend the material.
Chitosan is a natural biopolymer commerically derived from chitin from crustacean shells.
Our supplier estimates that the pH falls within the range of 6.5-8.0.
Chitosan is a biocompatible, antibacterial and environmentally friendly polyelectrolyte with a variety of applications including water treatment, chromatography, additives for cosmetics, textile treatment for antimicrobial activity, novel fibers for textiles, photographic papers, biodegradable films, biomedical devices, and microcapsule implants for controlled release in drug delivery. Please note that Product No. 419419 is for research purposes only, not for cosmetic or drug use.

Microparticles with controlled size and morphology are of significant interest in the fields of drug delivery and biopharmaceuticals. The objective of this study was to assess the effect of processing parameters on the ability to control the size and distribution of chitosan based microparticles, targeting diameter range of 1-10 µm. The effect of encapsulating bovine serum albumin (BSA), a model protein, as well as sodium tripolyphosphate (TPP), a cross-linker, was studied.
Chitin, a natural polysaccharide, is the second most abundant natural biopolymer in the world, after cellulose.
The development of new medical devices and pharmaceuticals plays an integral role in the medical industry. Both natural and synthetic polymers possess benefits that make them valuable components in therapeutics.
Chitosan is a naturally occurring polysaccharide ideally suited for use in medical supplies, devices, therapeutics, and diagnostics. The unique natural characteristics of chitosan include its cationic, biocompatible, biodegradable, non-toxic, non-immunogenic, and antimicrobial properties.
Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
