Abstract: Embodiments described herein relate to a tool comprising a cylindrical member having a cylindrical tube portion with a circular opening at a first end of the cylindrical member, and a protrusion disposed on an inner surface of the cylindrical tube portion. In various embodiments, the tool includes a plurality of protrusions that are disposed equal-distant from one another along a circumference on the inner surface of the cylindrical tube portion. In various embodiments, the cylindrical member comprises a second cylindrical tube portion with a second circular opening on a second end of the cylindrical member. In various embodiments, the protrusion has a varying height that gradually increases from a first end of the protrusion to a second end. In various embodiments, the protrusion is disposed at a slanted angle with respect to the circular opening where the first end is closer to the circular opening than the second end.

Abstract: Provided herein are systems, devices and methods for retaining chromatographic minicolumns in a holding fixture. A retaining apparatus may be provided with a pair of laterally spaced apart upright supports and a horizontal beam spanning between the upright supports to hold them in the laterally spaced apart relationship. The apparatus may be configured to contact a holder plate only along peripheral edges of the holder plate. The apparatus may be configured to slide along the holder plate after the minicolumns have been inserted therein, thereby retaining the minicolumns in the holder plate but allowing access to the minicolumns through vertical holes in the horizontal beam.

Abstract: Provided herein are systems, devices and methods for harvesting biological cells with a centrifuge. A biological cell harvesting centrifuge apparatus may be provided with a rectangularly shaped base and 21 laterally spaced apart upright supports. Each upright support may extend vertically upward from the base and have a hollow core. Each upright support may be configured to slidably receive and support either one, two or four vertical edges of either one, two or four 15 mL micro bioreactor vessels. The 21 upright supports may be arranged in a 3×7 array such that they form a 2×6 array of receptacles configured to slidably receive and support 12 of the bioreactor vessels. The upright supports may be configured to support at least 80% of the vertical edges of the bioreactor vessels.

Abstract: A method, system, and non-transitory computer readable medium for predicting cell viability of a cell culture in a bioreactor during a biomolecule manufacturing process are disclosed. In various embodiments, at least three manufacturing process parameters related to the process for manufacturing molecules are input into a machine learning model that is trained to predict cell viabilities. The trained machine learning model may then analyze the at least three manufacturing process parameters to generate an indicator of cell viability of the cell culture.

Abstract: A method, system, and non-transitory computer readable medium for predicting a glycan distribution of one or more glycans attached to molecules during a biomolecules manufacturing process are disclosed. In various embodiments, at least three manufacturing process parameters related to the process for manufacturing the molecules are input into a probabilistic graphical model that is trained to predict glycan distribution. The trained probabilistic graphical model may then analyze the at least three manufacturing process parameters to predict the distribution of the glycans that are attached to the molecules.

Abstract: A system for making a sterile connection of at least one conduit is provided. The system includes a clamp for securing the conduit and for delivering inductive energy to sterilize an interior of the conduit. The system includes an insert for delivering inductive energy to sterilize an interior of the conduit. The system includes a cradle for directly supporting the clamp and indirectly supporting the insert inside the conduit. The system includes an operating system and a device for generating inductive heat. Related methods, apparatuses, devices, systems, techniques and articles are also described.

Abstract: Provided herein is a tube rolling apparatus. The apparatus includes a first arm, a first roller rotatable around a first axis, a second arm, a second roller rotatable around a second axis, and optionally an advancing unit coupled to the first roller and configured to rotate the first roller around the first axis. Related systems and methods are also provided.
