The invention also concerns pyrogen-free assay systems coated with pyrogen-free antibodies for use in these tests.
Preferably the media is used for removing pyrogen from aqueous compositions.
Dispersion comprising the pyrogenic silicon-titanium mixed oxide powder.
The method results in a packaged, sterile nutrient composition which may be dissolved by the addition of sterile, pyrogen-free, water.
Test is valid if the value of the positive product control is within the range 50-200% in relation to the pure sample, and hemoglobin solution is pyrogen-free if the endotoxin level detected in the sample is 0,595EU/ml ( 5,95EU/g hemoglobin).
The stabiliser is, for example, a pyrogenic titanium dioxide and binds potential reaction partners or reaction products in the silicon oil.
Hydrophobic pyrogenic silica doped with potassium by means of aerosol is prepared by reacting a pyrogenic silica doped with potassium by means of aerosol with a surface-modifying agent.
Composite of layers which comprises a dielectric layer and a layer which comprises pyrogenic zinc oxide and is bonded to the dielectric layer.
The moulding is produced from high-purity fumed silica without addition of binders.
