This invention is related to high-throughput screening field, in particular to an application method for automatic micro droplet array screening system of picoliter scale precision. According to this invention, the fluid driving system and the capillary are fully filled with fluid of low thermal expansion coefficient as the carrier fluid to thoroughly empty air bubbles in the capillary; after that, immersing the sampling end of capillary into the oil phase that is mutually immiscible with aqueous sample to aspirate a section of oil phase into the capillary for isolation of aqueous sample and carrier fluid; once completed, immersing the sampling end of capillary into the sample/reagent storage tube to aspirate a certain volume of aqueous sample into the capillary; finally, moving the sampling end of capillary to the oil phase above microwells on microwell array chip, and pushing the sample solution in the capillary into microwells to form sample droplet. Quantitative metering of fluid and droplet generation according to this invention are provided with volume precision in picoliter, which can effectively minimize the consumption of sample/reagent, and save the testing cost during high-throughput screening.

Each of the first plurality of wells contains a sample processing consumable. The assembly can be used to load sample processing consumables into a sample processing instrument.

Methods and devices for amplification of nucleic acid

The present invention relates to methods and devices for amplifying nucleic acid, and, in particular, amplifying so as to generate products on a surface without the use of emulsions. In a preferred embodiment, a plurality of groups of amplified product are generated on the surface, each group positioned in different (typically predetermined) locations on said surface so as to create an array.

SAMPLE COLLECTION DEVICE

A sample collection device includes a tube, a closure and a partitioning member. The tube includes an opening and is used to receive a sampling swab. The closure is engaged with the tube for enclosing the opening. The partitioning member is disposed in the tube and includes a blocking portion and a position-limiting portion. The blocking portion is disposed close to the opening and covers a portion of the opening so as to leave another uncovered portion as an entrance for passing the sampling swab therethrough. The position-limiting portion is connected with the blocking portion and extended into the tube, so as to limit the sampling swab in a space corresponding to the entrance inside the tube after the sampling swab passes through the entrance.
