Laminar flow cabinets exist in both horizontal and vertical configurations, and there are many different types of cabinets with a variety of airflow patterns and acceptable uses. Cabinets may have a UV-C germicidal lamp to sterilize the interior and contents before use to prevent contamination of the experiment. Germicidal lamps are usually ...
A cleanroom or clean room is an engineered space that maintains a very low concentration of airborne particulates. It is well isolated, well controlled from contamination , and actively cleansed. Such rooms are commonly needed for scientific research and in industrial production for all nanoscale processes, such as semiconductor manufacturing.
The aim of cleanroom suitability tests is to determine the suitability of machines and operating utilities (air conditioning, venting, etc.) for use in cleanrooms. The tests must be carried out using measurement techniques as particle emission behavior cannot be adequately assessed by the naked eye or similar means.
The cleanroom software engineering process is a software development process intended to produce software with a certifiable level of reliability. The central principles are software development based on formal methods, incremental implementation under statistical quality control, and statistically sound testing.
A ventilated balance enclosure. Vented balance safety enclosures are used in pharmaceutical, chemical, biological, and toxicological laboratories to provide maximum containment for weighing operations in weighing scales.
ISO 14644-1 covers the classification of air cleanliness in cleanrooms and associated controlled environments. Classification in accordance with this standard is specified and accomplished exclusively in terms of concentration of airborne particulates. [6]
An unassembled IKEA flat-pack stool. Ready-to-assemble furniture (RTA), also known as knock-down furniture (KD), flat-pack furniture, or kit furniture, is a form of furniture that requires customer assembly.
A standard 19-inch server rack cabinet is typically 42u in height, 600 millimetres (24 in) wide, and 36 inches (914.40 mm) deep. [18] This comprises a volume of 974 L, or just under a cubic meter. Newer server rack cabinets come with adjustable mounting rails allowing the user to place the rails at a shorter depth if needed.
