Special rules of classification within this subclass
Classification Rules:
Classes of B01L 1/00-B01L 99/00 are given for invention information, i.e. the information is such that if you do a search on this subject-matter it is important to see the document. The definitions below give guidance to scope and limits of the respective classes. Additional information is classified with Indexing Codes in the range of B01L 1/00-B01L 99/00. These codes are used in combination or without a class in B01L. In addition to a class in B01L, Indexing Codes in the range of B01L 2200/00-B01L 2400/00 are applied were possible to all documents classified in B01L. Indexing Codes B01L 2200/00-B01L 2400/00 are not used for documents without a class in B01L. Also if documents have only an Indexing Code in the range of B01L 1/00-B01L 99/00, no Indexing Code is used.
Double classification:
Often double classification will be necessary, also within B01L itself. For example in cases documents relating to sample containers it might be that a document gets classified for the sample taking in A61B 10/0045, for sample storage in B01L 3/50 and in G01N for a specific analysis technique.
Circulation:
Due to the broad scope of B01L, and its status as residual group, there is no exhaustive list of neighbouring fields. In particular, it is important that documents relating to sample containers are also circulated to the specific analysis techniques mentioned in the document to allow double classification were appropriate. Some of the areas where documents need to be circulated regularly are: A61B, A61J, A61M, B01D, B01F, B01J, B29C, B81, B82, C12N, C12M, C12Q, F04B, F16K, G01F, and in particular G01N.

Definition statement
This subclass/group covers:

Definition statement
This subclass/group covers:
Handling of suspended solids or molecules independent from the bulk fluid flow. In general, the fluid flow direction of the bulk fluid is different from the flow direction of the component to be separated. Handling may comprise trapping, sorting, stretching, orientating of particles or molecules.
Usually particles or molecules are handled individually, thus they can be selectively handled irrespective of whether more particles or molecules of the same type/class exist in the sample. For example, a single DNA molecule may be stretched in a nanochannel although the sample comprises many more DNA molecules.
