Description
Micro filter crucible according to Pregl 4 ml P1 is a specialised glass filtration crucible intended for micro-scale analytical work following the classic Pregl method. It offers a working volume of 4,0 ml, a P1 filter plate of 10 mm diameter and a stem diameter of 6 mm, enabling controlled vacuum filtration of small sample quantities in quantitative organic analysis and microchemistry. The compact geometry minimises sample loss while retaining coarser precipitates on the defined P1 porosity plate. Produced by manufacturer Witeg, the crucible delivers dimensional consistency and reliable filtration performance for gravimetric determinations, micro-preparative procedures and teaching laboratories. Its 4,0 ml capacity suits elemental or organic microanalysis where only limited material is available. The unit integrates readily into standard micro-filtration assemblies used in analytical chemistry, pharmaceutical quality control and research environments. Supplied as a single piece with a net weight of 0,01 kg, this Pregl-type filter crucible provides a practical, durable solution for precise small-volume solid–liquid separations in everyday laboratory practice.

Questions about Micro filter funnels, acc. to Pregl 4.0
What is this article?
Micro filter funnels, acc. to Pregl 4.0 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Crucibles, inside Dishes, crucibles & porcelain, in Labware.
A crucible holds a sample in a furnace or over a flame, at temperatures that would soften a borosilicate beaker. Porcelain, platinum and glazed ceramic are different articles. The form, tall or wide, decides how fast a sample dries or ashes.
A dish is an open vessel for drying, evaporating or holding a solid. Porcelain and glazed ceramic take a higher temperature than borosilicate glass, which is why a crucible, not a beaker, goes into a furnace. A watch glass covers, or holds a small amount for drying. A mortar is for grinding. The temperature and the chemical, not the shape alone, choose the material. Laboratory ware of this family is listed under ISO laboratory ware.
