This parts list for BME 101/L (Applied Circuits for Bioengineers) Spring 2014, is based on the Winter 2014 list and the parts orders for that course. Prices are based on ordering enough parts for 40 kits, but do not include tax and shipping (see last year’s list for the prices last year including tax and shipping). Some parts based on buying for 50 (where that was a big price break).
