Product Details
Description
NEW German national law for the use of Uranyl compounds from depleted Uranium:
From 31.12.2018 the new German Radiation Protection Ordinance (StrSchV) of 29.11.2018, allows according to §5 paragraph 1 and Appendix 3, part B, item 9 the purchase of uranium compounds from depleted uranium for chemical-analytical and chemical-preparative purposes, e.g. for heavy metal staining for electron microscopy, up to an amount of uranium of 30 grams without permission.
Should you require further information, our radiation protection officer will be pleased to answer your questions.

Uranyless is a non-radioactive staining reagent as alternative to uranyl acetate. An optimized lanthanide Mix allows fast staining times. Uranyless is suitable for classical and negative staining procedures. The 30ml dispenser bottle is sufficient for staining of up to 1500 TEM grids.
UranyLess in 30% Ethanol is recommended for dense and lipid-rich tissue which is difficult to stain.
UranyLess in Acetone is used for contrasting cryo-fixed tissue during freeze substitution.Recommended for use with Lead Citrate (#DM22410).
