Microscope Slides - German made

Proscitech have selected a range of microscope slides from the German manufacturer, Knittel. These slides are good value for the best quality available. Cheap slides may be adequate for some purposes, but we recommend quality slides for any permanent preparation. The cost of a slide when compared with the cost of the final preparation is very small.

Glass Types

Soda glass is near clear, whereas older formulations had a green tinge when viewed side-on. New, low iron formulations have almost elminiated that and autofluorescence of slides is very low.
Refractive index (Na d) = 1.52; Density ρ= 2.49 kg/dm³; Coefficient of thermal expansion α= 9 x 10-6 K -1 @ 50-350 deg.C

Clear white glass (also known as water white, superwhite, pure white and super clear)  is clear and without any trace of colour. White glass is a very low-iron sodaglass, made by Schott and it is not auto-fluorescent.
Refractive indices at 20 degrees C: ne 546nm = 1.5251; nd 588nm = 1.5230. 
Both of types of Knittel glass slides are made by floating liquid glass on a hot tin surface; hence the name float-glass. Float-glass is produced down to 0.7mm; coverglass is treated mechanically. Float glass is particularly even in thickness and the sides are parallel - images remain very close to focus when moved on the microscope stage.
Microscope slides are not made of borosilicate glass - high quality coverslips are.
Slide Features
Twin frosted slides have one end (~ a third) frosted on both sides so either side may be used for labeling the slide.

Dimensions - Standard dimensions are according to ISO 8037/1:1986, 26 ( 0/-0.1mm x 76( 0/-0.1)mm, but with only 0.05mm variation on any slide. However, width and length refer to cut dimension; ground slides may be 0.5mm less. Standard slides are 1.0mm thick. Thicker slides are are available as indicated. These slides are exceptionally flat and parallel.
Surface is clean and perfectly wettable; glass imperfections are rare.
