The Ettan IPGphor II first-dimension isoelectric focusing system delivers high throughput, speed, reproducibility, and high protein-loading capacity.


Portable turbidity meter

14 July, 2004

Hanna microprocessor-based portable turbidity meters provide laboratory-grade accuracy for field or laboratory use. HI93703-11 measures turbidity from 0 to 1000 FTU (NTU). For best accuracy, HI93703-11 measures from 0.00 to 50.00 FTU in steps of 1/100th of FTU. The meter meets ISO 7027 requirements. HI93703-11 is equipped with an infrared LED light source. The infrared LED has a long life and maintains constant emission for the life of the instrument. The wavelength peaks at 890 nm, which provides the required intensity of diffused light even in samples with low turbidity values, and also reduces the interference from colours.


Analytical determination of ions in water

08 November, 2001

Water analyses are carried out by many different laboratories for a whole variety of constituents for as many different reasons. Techniques that involve the direct determination of ions present in the water play key roles in these analyses


pH electrodes evolve into the silicon age

08 March, 2001

Silicon chip pH sensors overcome breakage, maintenance and storage problems. Since the early 1930s when the first pH meter was invented, the core technology for quantitative pH measurement has, until recently, remained fundamentally unchanged
