Description

Tricaine Methanesulfonate is a white to off-white crystalline powder widely recognized as a safe and effective anesthetic for aquatic organisms. Its primary value lies in its ability to induce rapid anesthesia and analgesia in fish and amphibians with a wide margin of safety, making it indispensable for humane handling. This compound is a critical reagent for researchers, veterinarians, and aquaculture professionals involved in aquatic animal health management, surgical procedures, and scientific study.

Application

• Aquatic Animal Anesthesia: The primary application for the humane immobilization and anesthesia of fish, amphibians, and other aquatic species during transport, handling, and surgical procedures.
• Veterinary Medicine: Used by aquatic veterinarians for diagnostic sampling, minor surgeries, and treatment of ornamental and farmed fish.
• Research & Laboratory Science: Essential in zebrafish and other aquatic model organism research for inducing sedation during imaging, injections, and other experimental manipulations.
• Aquaculture Operations: Employed to reduce stress and physical injury during sorting, vaccination, and spawning induction processes in commercial fish farming.
• Euthanasia Solution: Formulated at higher concentrations to provide a humane and reliable method for euthanizing aquatic animals in accordance with ethical guidelines.
• Physiological Studies: Facilitates the study of fish physiology, metabolism, and response to environmental stressors by allowing stress-free examination.

Quality Control

Our Tricaine Methanesulfonate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for research and veterinary use. A Certificate of Analysis (COA) detailing purity, identity, and specific tests is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect stability and potency.
