Monolithic silica technology: A new age in chromatography. Chromolith® columns are based on silica so existing methods can be easily transferred with only minimal investment in new method development work. 'Sol-Gel' technology allows highly porous monolithic rods of silica to be formed. These feature a bimodal pore structure provides a unique combination of macropores and mesopores.

Water-free mounting media, such as Neo-Mount®, should be used for permanent mounting and long-term storage of samples. Slides processed in pathologyl laboratories need to be stored up to 10 years, whereby the staining results need to be stable and fading-out is not acceptable. Neo-Mount®, anhydrous mounting medium for microscopy is an extremely colour-stable mounting medium for microscopy, which is produced with solvents based on mixtures of aliphatic hydrocarbons. It contains an aromatic-free substitute for xylene, thus, Neo-Mount® needs to be combined with Neo-Clear® exclusively. Xylene must be avoided in the mounting step, as it will cause the slides to become cloudy and streaked. In addition, by placing the dehydrated slides on filter paper for approx. 1 minute prior to mounting, any excess Neo-Clear® should be circumvented, as air bubbles might arise under the cover slip. The same pre-condition should also be met when mounting specimens using cover slip machines; in this area, Neo-Clear® can be most efficiently eliminated by incubating the slides for 1 minute in an empty slide rack.

The high pressure homogeniser HPH is an inline dispersing machine for energy-efficient, continuous production of superfine emulsions. Compared to other IKA inline machines, the dispersing action of the high pressure homogeniser HPH is not based on the rotor/stator principle. The improved homogenising effect is achieved within the homogeniser by means of spontaneous decompression of the liquid from max. 2000 bar to an ambient pressure. With the same energy input, the IKA HPH produces considerably finer emulsions than conventional toothed ring dispersers. The use of high pressure homogenisers is recommended when a disintegration down to the nano range is required; however, these machines do achieve a smaller flow capacity than conventional dispersers. The high pressure homogeniser consists of a high pressure piston pump and a downstream homogenising valve. The pressure build-up within the HPH occurs by means of one or more piston pump(s) which, with the help of ceramic pistons, ensure(s) a volume flow that is independent of pressure and virtually pulsation free. The desired homogenising pressure can be infinitely adjusted. The pressure is reduced in a selected adjustable gap of the homogenizing valve. The quick pressure decrease in a moving medium leads to extremely high turbulences and cavitations, which then bring about the grinding of the raw product. The machine's design can be adapted to fit customer-specific tasks. The high pressure homogeniser is available in two sizes with either one or more piston(s) of varying Ø. These parameters determine the max. homogenising pressure (800 or 2000 bar) possible for a specific machine type, the minimal permitted feeding volume (up to 10 ml) as well as homogenising results and flow capacities.
