Abstract: A system and a method are disclosed for providing recommendations for sets of security operations for improving security of documents created or executed within an online document system. A supplier entity may select sets of security operations to be performed for a request provided to a signing entity. The online document system computes an aggregate measure of security for the selected sets of security operations and compares it to a threshold measure of security. If the aggregate measure is less than the threshold measure, the online document system uses a machine-learned model to identify additional sets of security operations that when added, results in an updated aggregate measure of security greater than the threshold. The additional sets of security operations are presented to the supplier entity for inclusion within a security operation workflow in combination with the selected sets of security operations.

Abstract: A separation container for extracting a portion of a sample for use or testing and method for preparing samples for downstream use or testing are provided. The separation container may include a body defining an internal chamber. The body may define an opening, and the body may be configured to receive the sample within the internal chamber. The separation container may further include a seal disposed across the opening, such that the seal may be configured to seal the opening of the body, and a plunger movably disposed at least partially inside the internal chamber. The plunger may be configured to be actuated to open the seal and express the portion of the sample.

Abstract: A bottle neck insert can include a cylindrical body having a first end and a second end, the cylindrical body having a plurality of rings; a flange provided at the first end, the flange protruding outwardly from the cylindrical body in a radial direction of the cylindrical body; and a valve section at the second end, the valve section having at least one slit, wherein the flange is configured to seat the insert onto a neck of a bottle and the valve section is configured to allow a pipette to pass through. A bottle storage system, can include a bottle having a neck with a smooth interior surface; an insert that is configured to fit inside the neck of the bottle; and a pipette assembly that is configured to proceed through the insert into the bottle.
