What are coated slides?
Slide coatings combine the high mechanical and thermal stability of metallic sliding surfaces with the superior tribological performance of modern polymeric composites. Therefore, they have become indispensable components in the manufacturing of light-weight, high-power, and safe vehicles.
What are glass slides made of?
soda lime glass
Microscope slides are usually made of optical quality glass, such as soda lime glass or borosilicate glass, but specialty plastics are also used.

Is glass slide transparent?
Our microscope slides are thin flat piece of glass used to hold objects for examination under a microscope made of high-quality white glass, no green tint with fine texture and transparency; these slides are also corrosion-resistant.
Do charged slides expire?
Q: Do charged slides lose their charge over time? A: Absolutely, yes. Usually manufacturers will assign an expiration date and the time would be one year. If you open a box, stuff oxidizes over time.
What are superfrost slides?
SuperFrost Slides. Thermo Scientific™ Superfrost Plus™ slides hold tissue sections on permanently without the need for expensive coatings in IHC and Anatomical Pathology applications. This treatment reduces tissue loss during staining as well as hours of slide preparation.
How do you make a glass slide hydrophobic?
Silanization of glass microscope slides using hexamethyldisil Azane (HMDS) can make slides hydrophobic dust repellent. Simply place the separated slides in a container like a wide mouth glass jar with an aluminium or Teflon lined cap.

What are frosted slides used for?
Frosted slides are best used in research or learning environments. The frosted tip of the slides allows the user to easily identify the specimen by writing directly on the slide.
What are microscope slides made of?
They are used for the preparation and archiving of specimens, as well as for microscopic investigation. These slides measure 76 mm x 26 mm x 1 mm thick. They are wettable, made from soda lime glass, pre-cleaned, and ready for use.
How long do prepared slides last?
A well prepared slide will last for 15-30 minutes before it dries up.
Are superfrost slides coated?
The Superfrost Plus® and Colorfrost Plus® frosted coatings take and retain most laboratory marking methods. The raised coating separates slides to help eliminate sticking, scratching or abrasion.
Are superfrost slides charged?
Superfrost Plus(+) glass slide are made by a process that place a permanent positive charge in the microscope slide.
Why do microscope slides expire?
Due to the composition of the glass, the alkaline content (Si02, CaO, MgO und Na20) in combination with humidity can lead to an alteration of the glass surface after a certain time. The alteration becomes visible as a fine white haze on the glass surface. The surface of the microscope slide can no longer be cleaned.

What is the function of glass slide?
A glass slide is a thin, flat, rectangular piece of glass that is used as a platform for microscopic specimen observation. A typical glass slide usually measures 25 mm wide by 75 mm, or 1 inch by 3 inches long, and is designed to fit under the stage clips on a microscope stage.
What are SuperFrost slides?
What is the difference between temporary and permanent slides?
Answer: When using a microscope, slides that are permanent can be examined and stored for a long time, while temporary slides are used for short-term observations. Permanent slides must be properly made for successful long-term storage.
What is used to preserve slides for years?
For specimens intended for making permanent microscope slide mounts, the killing and preserving solution of choice is AGA. This is a mixture of 10 parts 60% ethyl alcohol, 1 part glycerin and 1 part acetic acid.
