power supply outage

When the main power supply outage (PLN), the electricity supply required reserves and the conditions of the Generator-Set is expected to supply power mainly to priority loads. Generator can be used as a backup electrical system or "off-grid" (which depends...

Gel permeation chromatography

Gel permeation chromatography (GPC) involves steric separation of a sample, i.e., separation on the basis of size. Different detectors are used to analyze the resulting size fractions in order to quantify molecular weight and distribution, molecular...

micromanipulators

Crystal manipulation and harvesting have been done manually since the science of crystallography began. While the looping of larger crystals comes easily for some people, others never seem to get the knack. Some of the problems with manually harvesting...

bridge rectifier

There are basically two versions of the P3a: a 60W into 8 ohms (with ± 35V supply rails) and a 100W into 8 ohms (with ± 42V supply rails). I decided to build the version ± 35V, for two reasons. A 60W, which is more than enough. The other is that the...
