  • The basics of polarization (animated) | Spectroscopy Guides

    In many spectroscopic and photonics applications, it is desirable to work with light that has been polarized in a particular direction. In this article we explore what polarization is, and how it may be obtained from an unpolarized light source. Electro-magnetic radiation (light) What we generally refer to as “light” is more correctly known as 'electromagnetic ...

  • Short- and long-term orange dye effects on ammonium oxidizing and anammox bacteria activities

    The effects of orange azo dye over ammonia oxidizing bacteria (AOB) and anammox bacteria activities were tested. Performed batch tests indicated that concentrations lower than 650 mgorange/L stimulated AOB activity, while anammox bacteria activity was inhibited at concentrations higher than 25 mgorange/L. Long-term performance of a continuous stirred tank reactor (CSTR) for the partial ...

  • Influence of hydraulic retention time on the psychrophilic hydrolysis/acidogenesis of proteins

    The influence of the hydraulic retention time (HRT) on the anaerobic hydrolysis of complex substrates has been studied under psychrophilic conditions. For this purpose, a continuous stirred tank reactor was operated at 15 °C and neutral pH and gelatin was considered as a model protein. Three HRTs have been tested: 12, 21 and 36 h. Gelatin hydrolysis was greatly dependent on HRT, increasing ...

  • Your Evaporation Guide – Temperature difference

    Achieve higher distillation efficiency when using a rotary evaporator – Impact of temperature differences  There is a direct relationship between the heating bath temperature and the evaporation rate. The more energy applied to the evaporation side, and at the same time removed from the condensation side, the more efficient is the distillation. Furthermore, sufficient cooling ...

  • How do you heat in a vacuum oven?

    In a vacuum oven there is less air present to conduct the heat, so how do vacuum ovens ensure suitable heating of the samples? The Memmert VO series of vacuum ovens use a direct contact principle; each “thermoshelf” is heated so that all samples on that shelf receive heat by direct contact. The direct heating is ...
