A novel monolithic microactuator fabricated by 3D rapid direct manufacture
No full textIn this paper we present the world's first micropump entirely fabricated using a 3D direct manufacture process based on microstereolithography. The device employs a single pneumatically actuated membrane, with flow rectification provided by a nozzle/diffuser arrangement. A maximum flow rate of just over 2,000 mu l/min was achieved with a pneumatic pressure of 2 PSIG and a stroke rate of 96 Hz. The fabrication of actuator components using stereolithography apparatus (SLA) is a potentially major step towards the realisation of low-cost, disposable, rapid manufactured and fully integrated micro total analysis systems (mu TAS)

Standard pH Values for Potassium Hydrogenphthalate Reference Buffer Solutions in 10, 30 and 50 wt per cent 1,4-Dioxane + Water Mixed Solvents at Temperatures from 288.15 to 318.15 K
No full textStandard pH(S) values for 0.05 mol kg-1 potassium hydrogenphthalate (KHpH) reference buffer solutions in 10, 30 and 50% (w/w) 1,4-dioxane/water solvent mixtures within the temperature range 288.15-318.15 K are determined from e.m.f. measurements of the cell without transference Pt|H2|KHPh + KCl|AgCl|Ag|Pt. The consistency of the results is analysed by a recently described method of multilinear regression of the quantity p(aHγCl) as a function of both solution composition and temperature. The standard pH(S) determined can be reproduced to within ±0.01 by the equation pH(S) - 4.004 + 3.309w + 0.408z + 1.037w3 - 14.95zw2 + 27.1zw3, where w is the weight fraction of dioxane in the solvent mixture, z = (T - θ)/θ, and θ - 298.15 K. Values of the first ionization constant of phthalic acid (H2Ph; benzene-1,2-dicarboxylic acid) in the above solvent mixtures are also determined from e.m.f. measurements of the cell without transference Pt|H2|H2Ph + KHPh + KCl|AgCl|Ag|Pt

Determination of Standard pH Values for Potassium Hydrogenphthalate Reference Buffer Solutions in 10, 20, 50 64 and 84.2 wt per cent Methanol/Water Mixed Sovents at Temperatures from 283.15 to 313.15 K
No full textStandard pH0 values for 0.05 mol kg-1 potassium phthalate reference buffer solutions in 10, 20, 50, 64 and 84.2 wt % methanol/water solvent mixtures have been obtained from cells without transport, in the temperature range 283.15-313.15 K. The consistency of results has been analysed by a new method of multilinear regression of the quantity p(aHγCl) as a function of both temperature and solution composition. The pH° values found can be reproduced within ± 0.01 by the equation pH0 = 4.00 + 4.38x - 5.02x2 + 4.23x3 + 0.13z - 0.91xz, where x = mole fraction of methanol in the solvent mixture, z = (T - θ)/θ and θ = 298.15 K. Subsidiary values of the first ionization constant of o-phthalic acid in the above solvent mixtures have also been obtained by the buffered cell method
