FLUID DISTRIBUTION SYSTEM
20230338944 · 2023-10-26 ·

There is disclosed a fluid distribution system for distributing fluid from a single source to a plurality of downstream receptacles. The system has a distribution manifold assembly with a single inlet and a plurality of outlets arrayed around a circumferential outer periphery. The outlets may be directed to the different receptacles which each have their own vent filter, or each receptacle connects back to the distribution manifold for common venting. The distribution manifold assembly may be formed by identical fluid and vent manifolds with cylindrical exteriors, or by identical fluid and vent manifolds surrounded by cylindrical frame members, to form a compact cylindrical combined assembly. Flexible conduits connect the manifold assembly to a plurality of receptacles, and a consumable subsystem of the manifold assembly, conduits and receptacle caps may be pre-assembled for ease of use.

SMALL VOLUME SYSTEM AND METHODS OF EVALUATING THE STABILITY OF BIOPHARMACEUTICAL COMPOSITIONS

An analysis container includes an outer tube and a plurality of inner tubes. The outer tube defines a buffer volume that is configured to receive a buffer material. The plurality of inner tubes is disposed within the buffer volume. Each inner tube has an inner diameter equal to or less than 6 mm and is configured to receive a biopharmaceutical composition therein. The outer tube is configured such that the buffer material and the biopharmaceutical composition are axially frozen.

Evacuated blood collection tubes containing protease inhibitors for the assessment of contact system activation

Disclosed herein are evacuated blood collection tubes comprising protease inhibitor cocktails in liquid form and uses thereof for assessing features associated with the contact system in a subject, including the endogenous level of contact system activation, the endogenous level of a drug that targets a component of contact system during treatment, and/or the immunogenicity of such a drug.

20220276138 · 2022-09-01 ·

An analytic plate or other substrate having a permanent etchable, laserable, and/or developable marking surface coating (referred to herein as an “etchable coating” or as a “developable coating”) that is present on at least a portion of any side or surface thereof and is used to deposit a permanent indicium thereon, and a method of using the analytic plate or substrate.

Method for processing polynucleotide-containing samples

Methods and systems for processing polynucleotides (e.g., DNA) are disclosed. A processing region includes one or more surfaces (e.g., particle surfaces) modified with ligands that retain polynucleotides under a first set of conditions (e.g., temperature and pH) and release the polynucleotides under a second set of conditions (e.g., higher temperature and/or more basic pH). The processing region can be used to, for example, concentrate polynucleotides of a sample and/or separate inhibitors of amplification reactions from the polynucleotides. Microfluidic devices with a processing region are disclosed.

Thawing methods and apparatus

The invention provides a method of thawing a sample comprised in a container, the method comprising the steps of: a) calculating an agitation program as a function of either or both of the sample volume and the type of the container, and the ice fraction in the sample, and optionally the thermal conductivity of the sample container; b) agitating said sample according to the program to agitate at least one region of the sample; and c) changing the agitation program applied to at least one region of the sample in response to changes in the sample volume and/or sample ice fraction. The invention further provides a method of reducing shearing to cells during a method of agitation, and methods for thawing a sample wherein a sample container is differentially heated. An apparatus for use in the methods is also provided, as is an apparatus for thawing and/or cooling a sample which comprises a resilient vessel wall.
