Create Container

Tracks the checkout status of an inventory item such as a Container. When laboratory samples need to be temporarily removed from storage (e.g., for an experiment), users can check them out, optionally adding a comment and assigning responsibility to a user or team (see Assignee). The record captures when the status was last modified. This enables sample tracking workflows and prevents conflicts when multiple users need access to the same samples.

Read model representing a fillable position in a box or plate.

Provides expiration tracking for inventory items such as containers and their contents. The expirationDate may be explicitly set on the container or inherited from the stored entity's properties. The isExpired flag is a computed convenience field that returns true if the current date is past the expiration date. Items without an expiration date are considered non-expiring (isExpired returns false).

Represents a quantity with an associated unit of measurement within Benchling's inventory system. Measurements are used throughout inventory to track container volumes, sample masses, concentrations, and other quantitative values. Each Measurement pairs a numeric value with a Unit (see Unit) to provide context-aware quantity handling. For example, a container might have a Measurement of 500 uL for its volume. Unlike ContainerQuantity which provides a simpler representation, Measurement supports the full Unit system with dimensional conversions.

Represents the complete experimental designation of a well or container within an assay, combining a primary role (see PrimaryExperimentalRole), replicate group number, and optional subrole. The group field identifies replicate sets: wells with the same primary role and group number are treated as technical replicates for statistical analysis. The subrole field provides additional categorization for controls (e.g., POSITIVE, NEGATIVE, MAXIMUM, MINIMUM); only CONTROL primary roles may have subroles. ExperimentalRole is used in plate-based workflows to define experimental layouts (see PlateMapPosition) and annotate wells in FixedPlate and Container objects.
