Roti Histol, voor Histologie, 1 Liter

Bestel
Excellent as clearing agent and for dewaxing histological cuts. Alternative for xylene.
Roti®-Histol is a natural product, manufactured from untreated orange peel. It consists of 96-98 % limonene, a terpene with a characteristic odour of lemon or orange.
Roti®-Histol replaces current clearing agents without the need for changing working procedures. No harmful vapours! It can be mixed with IPA, butanol, ethanol and all standard embedding media.
Clearing with Roti®-Histol prevents tissue samples from hardening and brittleness. It is particularly suitable for all histological hand work which usually exposes the user to solvent vapours in high concentrations.

Bestel
 
Roti®-Mount Aqua is an aqueous solution of polyacrylate resin used for mounting of paraffin sections and cryostat sections directly after staining. The solution is ready to use. Colours and tissue structures are preserved in an optimal way. For long-term preserving of fluorescent dyes we recommend Roti®-Mount FluorCare (Art. No. HP19).
Application:
Residues of staining solution are removed by rinsing with buffer or destilled water. Afterwards the specimens are mounted with Roti®-Mount Aqua.
Storage:
Store at 2-8 °C in the dark, shelf life minimum 2 years

Aqueous coverslip sealant

.Non hazardous ingredients
.Solvent free
.Solidification by light

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.
