SpecificationA list of tests, references to analytical procedures, and appropriate acceptance criteria which are numerical limits, ranges, or other criteria for the tests described. It establishes the set of criteria to which a drug substance or drug product should conform to be considered acceptable for its intended use. “Conformance to specifications” means that the drug substance and / or drug product, when tested according to the listed analytical procedures, will meet the listed acceptance criteria. Specifications are critical quality standards that are proposed and justified by the manufacturer and approved by regulatory authorities.

Thimble Connectionan FSI accessory which is deisgned for the secure connection between flex tubing and enclosure (or remote Fan/Filter housing) exhaust port. Ultimately assists in the connection of the enclosure to a house-exhaust system
Time-Weighted Average (TWA)an average exposure concentration value which a sum of exposure per unit time, weighted by the total time of sampled exposure
Tissue Trimmingaka. histological tissue sample preparation; a biological or biotechnical operation performed to create samples for future processing
Titrationa deductive chemical laboratory method which is used to determine the concentration of an indentified analyte. A known concentration of titrant (placed into the sample to "tease" it) reacts with the analyte. The volume of titrant placed into the sample immediately at the point of reaction is known as the "titration volume"
TOCTotal organic carbon (TOC) is the amount of carbon bound in an organic compound and is often used as a non-specific indicator of water quality or cleanliness of pharmaceutical manufacturing equipment.
Top Mount Carbon Enclosuresan enclosure which features a Fan/Filter Housing on the top; specifically, this type of FSI enclosure contains at least one filter capable of filtering an organic [typically non-particulate] substance
Top Mount Fan Housingsa component of a top-mount enclosure (e.g. ETA Series, EHA Series, etc.), located on the top of the enclosure working area; isolates the fan and filter(s) from the surrounding environment
Top Mount Filter Replacementsif the the enclosure in need of filter replacement is a bag-in-bag-out enclosure (ETA, EHA, and custom enclosures based the these series), a replacement filter kit is required to safely replace the filter. If the enclosure in need of replacement is not a BIBO model, then the replacement filter is typically shipped without additional supplies
Top Mount Safety Enclosuresee ETA Series or EHA Series
Top Mount TechnologySee ETA or EHA Series
Top-Mount Enclosure a style of filtration featured on FSI enclosures which entails an FFH mounted above the top plenum; works in conjunction with airfoils and plenums to facilitatte laminar flow across the workspace
Transfer Portdead air box for the transfer of materials in and out of an enclosure.
Tray Dryer Tray drying is a batch process used to dry materials that are liquid or wet cake. The input materials are batched, placed into trays and loaded into AVEKA's overhead ovens for drying. Tray drying works well for material that requires more gentle processing or cannot be atomized in an air stream due to viscosity.
Two Position Draft Shield EnclosuresFlow Science enclosures which feature a draft shield capable of being configured in two distinct locations while retaining containment
