A process and closure arrangement is provided for isolating purified biological material. The process includes placing biological materials in separate lysis vessels, adding lysis liquids to the biological materials in the lysis vessels, and transferring the liquids in the lysis vessels into a matrix unit. The liquids in the matrix vessels of the matrix unit are extracted through outlet openings during which the liquids flow through matrices and the matrix unit is placed on a collecting unit with collecting vessels which are arranged such that at least the outlet openings of the matrix vessels extend into the collecting vessels. The matrix vessels are with elution fluid and elution fluids from the matrix vessels are extracted through their outlet openings during which the elution fluids flow through the matrices and the elution fluids which are enriched with biological material are collected in the collecting vessels.

System for providing biological materials

A procedure for the release and isolation of nucleic acids from biological compartments of a sample always uses an instrument that can hold one or more sample processsing vessels, maintain the sample processing vessels at a constant temperature, shake the sample processing vessels and separate magnetic particles by means of magnetic force. This system greatly simplifies the isolation of nucleic acids.

System for releasing and isolating nucleic acids

System and process for isolating purified biological materials with a collecting unit which has collecting vessels that are accessible from above with a matrix unit in which matrix vessels are arranged in a holder as well as a closure unit which can be placed on the collecting unit to close the collecting vessel. In addition the invention also concerns a system having a collecting unit, a matrix unit, and a closure unit as well as a lysis unit and a waste unit. Moreover a new closure arrangement is disclosed which is suitable for closing vessels in which there is excess pressure.

Method of isolating a biological material

Subject matter of the invention is a method of binding a biological material to a solid phase by providing a sample liquid containing the biological material in a sample vessel (A) having an inner contour (A17); then a hollow body (C) which has a contour (C12) that matches the inner contour (A17) is introduced into the sample vessel (A) while being closed with respect to the sample vessel by means of a porous matrix (C11); the sample liquid can enter the structural form (C) through the porous matrix (C11). This method is easy to automate and reduces the generation of aerosols.

Method of binding a biological material

A lid for closing an opening of a vessel includes a lid body configured to engage the opening, with the vessel having a defined shape. The lid body includes an engagement part which engages a corresponding surface of the vessel, thereby closing the opening. A handling element is disposed on an outer portion of the lid, with the handling element extending in parallel with an axis of the vessel. The handling element is for handling the lid for opening and closing the vessel.

Lid for closing vessels

A system for the temperature adjustment treatment of liquids, especially during the isolation and amplification of nucleic acids with a reusable thermostat element and a disposable heating element has the advantage of a particularly simple means of conducting temperature adjustment treatments. This system facilitates the execution of sample preparation and amplification in a single vessel.

System for the temperature adjustment treatment of liquid samples

A method for the repeated transfer of liquids from one of several storage containers into a transfer container wherein protective tips are placed onto a tip of a pipette in order to avoid contamination.

Method for the repeated transfer of liquids

A vessel for reducing contamination of liquids is formed of a vessel body with an inlet opening and an outlet opening therein. A closing device is attached to the vessel body adjacent the outlet opening. The closing device closes the outlet opening, and includes a normally closed one-way valve which is openable by a predetermined pressure from within the vessel body.

Vessel for reducing contamination in the treatment of liquids

System for the automatic operation of reactions using several vessels which can be closed by individual closures using a device for automatically opening the closures.

System for opening closures of vessels and for the contamination-free

Method of separating a component of a liquid from other components by immobilizing the component to suspended magnetic particles in a vessel, immersing a magnetic device into the vessel while the device is separated from the liquid by means of a protective sleeve made of a non-magnetic material. Then the non-immobilized components are removed. The invention also addresses a device suitable for implementing this method. With said method and device, resuspension is achieved in a simple and efficient manner.

Method of magnetically separating liquid components

Device for the treatment of nucleic acids from the sample, comprising a first reaction chamber for separating the nucleic acids from other sample components, and a second reaction chamber for the amplification of the nucleic acids, connected to said first reaction chamber via a controllable transport path.

Device for treating nucleic acids from a sample

The present invention provides a process for the determination of the thyroxine-binding capacity in serum, wherein, for the calibration, there are used at least two different standard solutions which contain substantially the same amount of thyroxine-binding globulin but a differing content of thyroxine. The present invention also provides a standard solution for the determination of the thyroxine-binding capacity containing thyroxine-binding globulin dissolved in a buffer system.
