  • Patent number: 10981169
    Abstract: A micro-vial for handling micro-volume of sample fluids. The interior wall defined in the vial has a cylindrical sample section, a wider cylindrical alignment section, a tapered or conical guide section, and a relatively large cylindrical body section, arranged in sequence in that order along the center axis of the vial. The sample section holds a small volume of a sample fluid and receives the tip end of a capillary tube. The alignment section has a larger diameter than the sample section, receiving a cylindrical support that coaxially supports the relatively fragile capillary tube. The tip of the capillary tube dips into the micro-volume of sample fluid held in the sample section. The conical section guides the capillary tube and the support tube into the alignment section and the tip of the capillary tube into the sample section.

  • Patent number: 10478820
    Abstract: An article for performing a reaction includes a reagent well having a side wall, a bottom wall and an open upper end. A lyophilized reagent is retained within the well by a non-integral retention feature that is inserted into the open upper end of the well and fixed to a side wall above the reagent. An opening in the retention feature is smaller than the diameter of the reagent, but is sized to permit a pipette tip to be inserted into the well. The retention feature may be a collar fixed to the side wall and may include fingers extending axially into the well. The well and the retention feature may be correspondingly tapered. A method for reconstituting a lyophilized reagent includes the steps of drawing into a pipette tip attached to an automated pipettor an amount of a diluent and dispensing the diluent into the reagent well to thereby reconstitute the lyophilized reagent.

The microplate assembly may be fabricated using a method involving applying an etching solution to each of the top and bottom plates to create the domes and microwells. Additionally, etching solution may be applied to the bottom plate to create a raised lip region around each of the microwells. The etched-away areas surrounding the lip regions facilitate the changing of microwell solution without disrupting the samples.

  • Patent number: 8647593
    Abstract: Magnetic microplate assemblies are disclosed for assaying of biological activated magnetic particles from a supernatant. The assemblies include a magnetic microplate holder and a microplate including a plurality of wells for retaining the magnetic particles. The microplate holder includes a plurality of magnets for attracting the magnetic particles to the wells and a plurality of detents for securing the microplate in the holder. The detents allow the microplate to be tightly retained in the holder when the assembly is turned over to discard supernatant and wash buffer applied to rinse supernatant from the magnetic particles.
