Figure 22 – Typical conical tube
Figure 23 illustrates a typical conical tube commonly employed for various purposes such as sample storage in freezers or during processes like centrifugation. These tubes are designed for singular sample use. A distinct container identifier can be assigned during manufacturing or applied later using a printed label provided by the user. In cases where a label is used, it might also directly display the sample identifier of the contents, although this isn't always guaranteed.

The table shows an example of a Samples list as it might be used to initiate a separation run on a centrifuge. Each tube is accompanied by its unique container identifier and individual sample identifier. Given the vital role of balanced mass distribution in a centrifuge's rotor for optimal functioning, the orchestrating application (e.g., LIMS or ELN) for this process step recommends specific tube placement within the rotor. This recommendation is founded on the application's knowledge of the individual sample weights.
It's important to highlight that the precise meanings and formats of the Position and CustomData properties fall beyond the scope of the LADS Companion Specification. However, forthcoming companion specifications utilizing LADS might delve into these aspects in greater detail.
