EMS Technical Data Sheets
Entellan® Rapid Mounting Media for Microscope Slides
EMS Catalog #14800
Composition:
Entellan® New is a solution of polymers in xylene.
Uses:
The combination of several synthetic resins makes Entellan® a particularly rapid embedding agent. It can be used for all dehydrated microscopic preparations.
Embedded preparations can be filed for years without changes occurring in their color. Constant properties ensure its high quality.
Properties:
| Setting time at room temperature | 20 minutes | |
| Intrinsic color | Colorless; absolutely transparent | |
| Neutrality Acid number | <2.50 | |
| Refractive Index | nd20 1.490 - 1.500 | |
| Refraction to daylight & UV light | not turbid | |
| Heat resistance | up to 90°C | |
| Cold resistance | down to -17°C | |
| Intrinsic fluorescence under UV light | <50ppb quinine sulfate | |
| Indifference to biological stains | not to carmine, sudan III , toluidine | |
| Density 20 o/4°C | 0.940 - 0.960 | |
| Viscosity @ 20°C | <450cP | |
| Solubility dissolves in | acetone, ether, benzene, chloroform, dioxan, toluene, xylene | |
| Reaction to water | slight; immiscible with water | |
| Loss on drying | about 75% |
Use:
Cover the object with drops of Entellan® so that the space between the cover glass and the slide is completely filled. The cover glass must be sealed right up to each edge. Excess embedding agent can be removed with a cloth moistened with xylene.
In the case of histological and cytological preparations it is recommended that xylene be used as the final stage before embedding, so that turbidities caused by the action of alcohol can be avoided.
As a matter of precaution, we recommend that, as with other embedding agents, all work with Entellan® be carried out in a fume hood or in a well-ventilated room.
Note:
Recap the bottle immediately after use. Should Entellan® become to viscous, it can be brought back to the desired consistency by adding xylene. Store at room temperature.
