Abstract: A portable testing device includes a hosing with an integrated touchscreen display and a receptacle in which a sample holder containing a biological sample and reagent mixture can be placed. The portable testing device further includes an optical assembly positioned in the housing, an electronic assembly that is configured to receive data from the optical assembly and transmit it for display upon the touchscreen display, and a power supply in the housing to power the portable testing device. The optical assembly includes an excitation filter that extends across the entire optical assembly and an emission filter that extends across the entire optical assembly.

Abstract: A method for processing a biological material sample includes dispensing a sample into wells of an array tape from a sample plate, dispensing a reagent into the wells of the array tape from a reagent plate, and sealing the sample and the reagent in the array tape. The method further includes cooling the array tape and detecting biological material in the wells of the array tape.

Abstract: A process for making a butyl ester from butadiene by reacting butadiene or a hydrocarbon fraction containing butadiene with a saturated aliphatic monocarboxylic acid, wherein the catalyst is rhenium(VII) oxide or an organic sulphonic acid containing at least 2 sulphonic acid groups per molecule wherein the ratio of the number of carbon atoms to the number of sulphonic acid groups in the organic sulphonic acid is in the range 1:1 to 1:0.15. Preferred catalysts are organic disulphonic acids for example ethane-1,2-disulphonic acid. The process can be used for making unsaturated esters, or, by hydrogenation of the product, for making saturated esters such as for example butyl acetate. Catalyst can be purified and recycled to the reactor.
