Potentiometry measures the potential difference between an indicator electrode in a solution and a reference electrode. This provides a quantitative non-destructive measurement of a liquid sample. A common electrode is the glass-membrane electrode used in a pH meter., but various indicator electrodes are designed for specifically for various solutions. The potentiostat is an unloved staple in most wet-labs […]

Pairing Plastic Printed Parts Professionally with 3DHubs
Last week we saw Holden Lab at Newcastle University start a discussion about using threaded fasteners to secure 3D printed parts. Dr. Robert LeSuer pointed out an extremely thorough discussion on the matter on 3DHubs.com . 3DHubs has an incredible wealth of information on DIY construction, including an amazing cost analysis of 3D printing vs […]
Economical High-Temperature Water Bath Control and Monitoring
In the fanciful land of scientific suppliers, a temperature controlled water bath can run you hundreds to upwards of a thousand dollars. These devices are not particularly accurate in their temperature read out, and… you know what we could complain about these buckets of filth for paragraphs, but let’s just provide you with an alternative. […]

ThermoFisher, SigmaAldrich, VWR even gives you a “Lab Set up Guide” to help you spot discounts. If you are setting up a new lab, check with your distributors to find out if […]
BioBits — Synthetic Biology for K-12
This is the coolest thing about STEM education I’ve read in a while. A large team of researchers from Wyss, MIT, and Northwestern have figured out how to use freeze-dried cell parts (which in itself is a super cool technology) to create synthetic biology experiments for K-12 that can be stored on a shelf at room temperature […]
