Rotiseal is used to seal the edges of the coverslip. Solid at room temperature. Prior to use it is melted on a waterbath (max 50-55C), the it is applied around the edges of the coverslip by using a pipette or a glass rod. Exposure to light allows the sealant to harden within a short time.

Roticlear for Histologie, 1 Liter

Bestel
For dewaxing histological sections. Alternative product for xylene
Roticlear® consists of different hydrocarbons with only little own odour. It is practically free from aromatic compounds and can be mixed with IPA, butanol, ethanol and acetone.
Roticlear® can be used like xylole. The absorption capacity for paraffin is even better than that known from xylole. Therefore, water baths for removing the paraffin need not to be changed so frequently. Roticlear® produces non-sticky cuts and, due to a short evaporation period, enables fast and effective working.
Roticlear® can be used in automates without any difficulty.

Solvagreen, ontkalker, 500ml

Bestel
 

Tissues containing solid material such as bones or keratin are to be decalcified before paraffin embedding. Usually the specimens are treated with acids of different concentrations and mixtures.

An especially gentle method is decalcification with EDTA solution.

           
Decalcifier soft SOLVAGREEN® for histology

The solution contains 25 % EDTA.

   
The process of decalcification takes more time than acid decalcification (see Decalcifier standard, Art. No. 6483), e.g. bone biopsies need approx. 3‑4 days. The procedure can be accelerated by using a magnetic stirrer. The decalcification takes place in a weakly basic milieu.
Nucleic acids and enzymes are not affected; therefore, the solution is also suitable for immunological applications.
