A two-component paint system (1) comprises a medium pressure canister (10) with a paint, at least one solvent and at least one propellant, and a high pressure canister (20) with a hardener, at least one solvent, at least one propellant and an inert gas or inert gas mixture. An adapter (30) is configured to transfer the content of the high pressure canister (20) into the content of the medium pressure canister (10). The internal pressure of the high pressure canister (20) is at least 2 bars higher than the internal pressure of the medium pressure canister (10).

To sum up, by using the shaker for mixing liquids (1-7) (e.g. shampoo, soap, etc) with water right before use, an optimal dose of the liquid is used and appropriate solution is used. A dissolved mixture is applied to the hair/body to most significant part immediatelythe hair roots and the scalp. It works beneficial for the hair, especially the hair ends, preventing dry and split ends as the e.g. shampoo is not applied directly. The mixture is distributed more evenly throughout the hair, without adding additional water and washing out the unused shampoo. The foam evolves quicker and is greater, which makes the washing easier. The shaker enables the user to use multiple liquids at once if needed. The amount of the liquid used is decreased to an optimal dose for the user and is therefore also eco-friendly, as no excessive amount of liquid is used. The invention enables the user to close tap water/shower during use and therefore uses less water and is eco-friendly. With same advantages the shaker is used in pet care and with other liquids.

A specimen disrupting apparatus includes: a drive unit that rotates the lower portion of a container having a solution that includes a specimen, a great number of small diameter beads, and a large diameter bead stored therein; and a control unit that controls the drive unit. The control unit controls the drive unit such that the lower portion of the container rotates at two or more different rotational speeds which are changed continuously.

Provided are methods and devices for dissolving solid protein compositions, such as solid compositions comprising fibrinogen, in an aqueous solvent. The methods comprise use of a closed container containing a volume of solid fibrinogen composition and a head space wherein the pressure within the headspace is sub-atmospheric. Aqueous solvent is introduced into the container while maintain the sub-atmospheric pressure, and subsequent to addition of the solvent, the size of the headspace is decreased to bring the pressure to atmospheric pressure. The devices are suitable for use in the disclosed method.

The present invention relates to containers for holding liquid samples. The containers may be useful for mixing a liquid sample or lysing cells in a liquid sample. The invention also relates to methods of using the containers of the invention.

An apparatus having a plate mountable on an oscillating multi-function tool and having a plurality of sample apertures sized to receive sample vials. The sample apertures may be lined with resilient grommets or have a chamfered edge. The apparatus may further have a weighted base and housing with vibrating isolation means for holding the tool during operation. The apparatus may further have a timer to allow for timed operation. The method including providing a plate mounted on the arbor of an oscillating multi-function tool, inserting a sample vial in a sample aperture and turning on the tool. The method may further include operating the tool for a fixed time and providing a housing and base to hold the tool during operation.

Disclosed herein are devices, apparatuses, and methods for grinding of samples. A method includes securing a sample vial in a holder attached to a connecting linkage, the sample vial having a grinding media in the sample vial. The method includes rotating a crank that is operatively coupled to a proximal end of the connecting linkage at a proximal pivot point so that the proximal pivot point undergoes rotational motion. The method includes restricting a distal pivot point of the connecting linkage to a linear path, the distal pivot point near a distal end of the connecting linkage. A result being that the sample vial undergoes a combination of rotational and linear motion.

A unit for grinding biological samples, comprising a grinding device including at least two tubes having different volumes, suitable for being mounted on a support of the grinding device, each tube comprising an inner space having a height (h) along the axis of the corresponding tube, and being intended to contain samples to be ground, means for driving the support in a precession movement, the support having an axis the position of which varies by describing a cone, each tube being subjected to a movement (d) defined by the projection, onto the axis of said cone, of the distance between the extreme positions of a same point of the tube during the precession movement.

An integrated at least two component mixing and delivery system and method for creating a new mixture from a first component contained within a first enclosure and a second component contained within a second enclosure that is contained within the first enclosure and, via a series of operations that mix the two components and enable the application of through an applicator tip the placement of the new mixture on at least one surface or a portion thereof.

Embodiments of the present technology may include a method of forming an emulsion. The method may include flowing an oil stream and an aqueous stream into a coiled tube to form a mixture of an oil phase and an aqueous phase in the coiled tube. The method may also include flowing the mixture in the coiled tube against gravity and under laminar conditions. A plurality of beads may be disposed within the coiled tube. The method may further include mixing the oil phase and the aqueous phase in the coiled tube until the emulsion is formed.
