A simple apparatus for paraffin infiltration under reduced pressure (in vacuo)

A Simple Anæsthetic Apparatus

In the apparatus about to be described I make no claim to originality in design. It has been my endeavour to find the simplest form of anaesthetic apparatus which could, with slight adaptation, be used with reliability for intra-tracheal, intra-pharyngeal, or intra-nasal induction using ether with air or oxygen. This apparatus has been in constant use for the past 33r years in certain Indian mi...

A Simple Apparatus for Distilling Water

A simple anaesthetic apparatus for small animals.

This apparatus was developed for the anaesthesia of small animals, including infant and adult mice, rats, guinea-pigs, rabbits, and rhesus monkeys. The general layout of the apparatus is shown in the diagram. The apparatus consists of an electric pump which drives air through a two-way tap connected to two tubes in an ether container. One of the tubes reaches well below the surface of the ether...

A Simple Apparatus for Thin-layer Chromatography.

Thin-layer chromatography was introduced by Stahl (1956) and has advantages over paper chromatography in speed, resolution, and smaller sample size. Also, the physical nature of the thin layer allows its treatment, where necessary, with strong acids and alkalis. It has been found possible to construct a satisfactory, cheap, and simple apparatus for the preparation of thin layers on glass carrie...
