A micro-Kjeldahl apparatus

A steam distillation apparatus suitable for micro-Kjeldahl analysis.

The Estimation of Non-Protein Nitrogen in Blood by a Micro-Kjeldahl Method.

A new micro-respirometer with automatic setting and recording apparatus.

The instrument was designed to measure the O2 uptake of living material which consumes between o-oi and 5-0 yl. O2/ hr. Its accuracy is +o-ooi /u.1., and it has the following advantages over other micro-respirometers of similar sensitivity. (a) It is robust, easy to handle and is suitable for routine use. (b) The respirometer constant is independent of the gas volume of the reaction vessel. (c)...

A Uniform Pressure Apparatus for Micro/Nanoimprint Lithography Equipment

Nanoimprint lithography (NIL) has overcome the limitation of light diffraction. It is capable of printing features less than 10nm in size with high lithographic resolution, high manufacturing speed, and low production cost. The uniformity of pressure, however, remains a critical issue. To improve the uniformity of pressure, we developed a flexible uniform pressure component based on Pascal’s La...
