Insanely Great Science

Four more mobile science apps

I’ve added four more apps to the mobile science page.

The Aldrich Handbook of Fine Chemicals for your iPad, Convenient alphabetical browsing of chemical substances in list or grid view Substance pages with key technical properties, chemical structures, and links to corresponding products on Sigma-Aldrich.com for additional information,Ability to search by product name, synonym, CAS number, and product number with alphabetically returned results.

Molarity a chemistry calculator tool that generates lab-ready directions describing how to prepare an acid or base solution of a specified molarity or normality from a concentrated acid or base solution. A second tab includes a general molarity function that calculates the mass of any reagent needed to prepare a given volume of solution of desired molarity. A third tab features a stock dilution function that calculates how to dilute a stock solution of any known molarity to your desired volume and molarity.

HPLC Calc Calculates conditions for transfer of an isocratic or gradient method from one HPLC column to another. Recommends flow rates for analytical columns. Allows method scaling from microbore through preparative column range based on the 2 sets of column variables (column length, column I.D., particle size) and current method conditions (flow rate, injection volume, pressure, run time, equilibration time).

CloningBench Restriction Enzyme Finder - Search by cut-site, name or buffer type, obtain technical data that you can share easily with others and order directly from your mobile device. Double Digest Finder - Find the correct buffer and concentration when digesting DNA with two restriction enzymes. Competent Cell Selection Guide - Quickly find the right competent cell for your cloning application and order easily. Search for chemically competent or electrocompetent cells, desired transformation efficiency, specialized application or packaging format that suits your needs.
