摘要:
The invention relates to a temperature-control element (4) for a multiwell plate (1), which comprises a plurality of cavities (2) arranged in rows and columns for freezing and/or thawing biological samples. The temperature-control element (4) comprises a base body (6) which is made of a thermally conductive material and is flown through by a temperature-control fluid; and a plurality of protruding temperature-control fingers (5) arranged in rows and columns on an upper side of the base body (6), which are connected in a thermally conductive manner to the base body (6), wherein a grid spacing of the temperature control fingers (5) corresponds to a grid spacing of the cavities (2) of the multiwell plate (1). The invention further relates to a device and method for freezing biological samples, in particular for cryopreservation, and/or thawing biological samples, in particular a cryopreserved sample.

The invention relates to an encapsulating device (100), which is designed to encapsulate a sample (1, 2) in a polymer capsule, comprising a drop generator (10), which is designed to provide a drop (3) of a suspension, which drop contains the sample (1), and a cross-linking device (20), which is designed to polymerize the drop (3), wherein the drop generator (10) has a retaining device (11), which is designed to accommodate the drop (3) in a hanging state, and the cross-linking device (20) is designed to feed a polymerization substance to the hanging drop (3) on the retaining device (11) and to form the polymer capsule. The invention further relates to a method for encapsulating a sample (1, 2) in a polymer capsule.
摘要:
A sample carrier unit (100), in particular for biological samples, is described which comprises a sample uptake unit (10) which is equipped for taking up at least one sample, a data storage unit (20) which is equipped for the storage of sample data that relate to the at least one sample, and to a key storage unit (30) having at least one key store (31, 32, 33), wherein the key storage unit (30) is equipped for storing key data in the at least one key store (31, 32, 33). At least one key store (31, 32, 33) of the key storage unit (30) can be arranged so as to be separable from the sample carrier unit (100). In addition, a data processing unit (200) which is configured for coupling to the sample carrier unit (100) and a method for processing sample data are described, which sample data are encrypted using at least one cryptological key which is stored in the key storage unit (30).
摘要:
The invention relates to a method for conserving at least one biological deep-sea organism (1) comprising the steps of collecting the biological organism (1) in a deep-sea trapping device (110); cooling the biological organism (1) with a cooling device (120), wherein the biological organism (1) is put in a frozen condition; and moving the frozen biological organism (1), preferably with the trapping device (110), to a normal-pressure environment. The invention further relates to a conservation apparatus (100) for conserving at least one biological deep-sea organism (1).
摘要:
The invention relates to a sample collection method, in particular for obtaining early infection blood samples from freshly infected patients in the diagnostic interval of an antibody-based HIV test. The method comprises the following steps: first biological samples are drawn from a plurality of living beings (3-7) in a sample; said samples are subjected to analysis using a first diagnostic test for a specific substance of interest; the living beings (3-7) that have tested positive are excluded from the sample; at least the samples that have tested negative are preserved; after a specific waiting period, second biological samples are drawn from the living beings remaining in the sample (3-7); said samples are subjected to analysis using a second diagnostic test for the substance of interest; and finally the cryopreserved samples of those living beings (3-7), with first negative and then positive tests are selected. The invention also relates to a suitable sample collection device.
