6+ Test Tube Holder Definition: Uses & More

A laboratory apparatus designed to securely hold test tubes is often utilized in scientific experiments and procedures. This device provides stability, preventing accidental spills or breakage. Typically constructed from materials such as metal, plastic, or wood, it can feature multiple slots or a single clamp-like mechanism to accommodate various tube sizes. Examples range from simple racks to more elaborate designs with adjustable components.

The importance of a reliable holding implement lies in ensuring safety during heating, mixing, or observation processes. It minimizes the risk of direct contact with potentially hazardous substances and allows for hands-free operation, improving efficiency. Historically, rudimentary versions were crafted from available materials, evolving into specialized equipment tailored for the precision demands of modern research.

6+ What is a Marketing Authorization Holder Definition?

The entity legally responsible for placing a pharmaceutical product on the market within a specific jurisdiction is a critical component of the regulatory landscape. This entity, granted authorization by relevant health authorities, bears the responsibility for ensuring the product’s safety, efficacy, and quality throughout its lifecycle. They are accountable for all aspects of the medicine, from its manufacture and control to post-market surveillance and reporting of adverse events. An example includes a pharmaceutical company that has successfully navigated the regulatory approval process and obtained permission to sell a specific drug in a particular country.

This concept is fundamental to safeguarding public health. By clearly assigning responsibility for a medicinal product, regulatory agencies can effectively monitor and enforce compliance with established standards. This system facilitates traceability and accountability, enabling prompt action in case of safety concerns or quality defects. Historically, this framework evolved as a response to instances of substandard or harmful medicines reaching the market, necessitating a structured system for oversight and control to protect patient welfare and maintain trust in the pharmaceutical industry.
