A presentation detailing the characteristics of a laboratory apparatus designed to hold multiple test tubes upright is essential for proper identification and selection. Such presentations generally cover aspects such as material composition (e.g., metal, plastic, wood), dimensions (length, width, height, hole diameter), capacity (number of tubes it can hold), and any special features (e.g., autoclavability, chemical resistance, drain pegs). For example, a “stainless steel, 24-well rack suitable for 16mm diameter tubes and autoclavable at 121C” constitutes a comprehensive rendering.
The provision of detailed characteristics facilitates appropriate choice for specific experimental needs. This clarity minimizes the risk of selecting inappropriate equipment, which can lead to experimental error or damage to the tubes themselves. Historically, these descriptors have evolved from simple, general terms to highly specific specifications as laboratory practices have become increasingly standardized and regulated, ensuring reproducibility and safety.
