Aqualife TMS (MS 222)


Syndel's Aqualife TMS (MS-222, TMS, tricaine methanesulfonate, Finquel) is a Health Canada approved fish anesthetic (DIN 02168510) used for the temporary immobilization of fish, amphibians, and other aquatic cold-blooded animals (poikilotherms).  Tricaine-S has long been recognized as a valuable tool for the proper handling of these animals during manual spawning (fish stripping), weighing, measuring, marking, surgical operations, transport, photography, and research. Aqualife TMS (MS-222) is a fine powder that is mixed with water prior to use.  MS-222 is safe and effective for the anesthesia of fish when used as directed.  In Canada, a Veterinary Prescription is required to purchase this product.

Syndel is the world's largest manufacturer of Aqualife TMS.  It is made in our FDA inspected Ferndale, Washington USA manufacturing plant according to Good Manufacturing Practices (GMP) and Good Laboratory Practices (GLP), which ensures the purity, strength, and quality of the product.
