摘要:
Purified agarose is recovered from agar or impure agarose by dissolving the agar or agarose in a lower alkylene glycol at elevated temperature, cooling the agar- or agarose-containing glycol solution to induce precipitation of a purified agarose product, and recovering the precipitated agarose product.
摘要:
57 A device for replicating moist bacterial or other cell colonies including a resilient backing layer and a cell colony transfer surface which includes a hydrophilic material and which is absorbent, porous, compliant and exhibits less resilience than said backing layer.
摘要:
A three dimensional porous matrix, such as a reticulated open-cell foam, having within its matrix structure a mechanically-fractured hydrogel containing a network of fracture channels. The mechanically-fractured hydrogel may be a gel that has been partially dewatered by compression of the gel in situ. The porosity of the gel-in-matrix makes it useful for chromatographic applications and for immobilization of biologically-active components, where efficient, intimate contact of the hydrogel with a liquid medium is important.

摘要:
A Well Indicating Device which is useful in laboratory procedures for identifying, in a predetermined but variable sequence, wells of a plurality of independent but interrelated substance-receiving wells, such as of a microtiter tray, which are subject of manipulation.
摘要:
A device and method of making and using the same in performing manual and automated chemical reactions and analyses of clinical assay mediums. Such device including a solid, microporous element formed of adsorbent material and having walls defining an internal cell structure comprised of interconnecting cells within which is contained a precise, measured quantity of reagents.
