Quantification of samples is an integral step in numerous biological and chemical experiments. Spectrophotometers are often used together with colorimetric assays that react with the compound of interest in the samples. However, spectrophotometers are often costly, bulky and immobile. To increase the convenience and ease the process of spectrophotometry, the APD SpectBT was developed using the Arduino-based platform to create a smartphone dependent mobile spectrophotometer.

Smartphones doubling up as laboratory equipment are increasingly in demand for convenience and portability. VibraTilt is a free smartphone app with a simple interface on both the iOS and Android operating systems that functions as both an accelerometer and a gyroscope. Leveraging on in-built sensors, the portable accelerometer bubble level can be used in labs to determine the tilt of surfaces.
