|StarFrost ® microscope slides
KNITTEL StarFrost® slides are globally
protected as a registered trademark of Waldemar Knittel GmbH and in the EU
under patented licence. This is a guarantee to you to receive our high-value,
inspected, quality product. These slides can be easily recognised by the
colour-printed marking areas and it offers you an additional differentiating
factor for your substrates in medical or science institutions and
slides carry on the wettable top surface, a coloured translucent but
opaque marking area. Available in our 6 standard colours: white, blue,
pink, yellow, green and orange, all of which can be marked like a normal
||As well as their markings with
pencil (#4 = 2H), ballpoint pen, marker and different
laboratory-printers (e.g. Leica XPS) or special solvent resistant
laboratory-markers, different substrates can now be additionally
identified by the colour of the slide. It makes it quicker and safer to
separate slides or specimens e.g. by the urgency of the matter, testing
method, staining technique, patient, etc .
Our special colour-printed marking area is
resistant to all common chemicals used in the laboratories. On our
StarFrost® Slides the printed ink works as a spacer to prevent scratches or
sticking of the slides when stacking or magazining them. Additionally, there
has been a lower susceptibility to failure in automated laboratory systems
From the single side printing of our coloured marking area and our adjacent
printed trademark “StarFrost®“, the user always knows the best surface to be
used (NB: With our standard Floatglass it is the same side as the best
wettable surface (airside) of the slide). The printing also makes it easier
to focus the microscope on the used surface and even in the dark you can
feel whether you have the correct side.
The KNITTEL StarFrost® slides are cleaned
by a new, KNITTEL-developed, globally unique cleaning-procedure, which is
also friendly to the environment. Our cleaning-process offers the best
wettability and the optimum condition of the marking area.
Like our standard microscope slides,
StarFrost® slides are available in the familiar edge formats, such as cut,
ground 90° with or without clipped corners, ground 45° and bevelled edged
StarFrost® slides. Like all our other microscope slides, we take care to
achieve the best processing, washing, examination and packing.
For larger demand, StarFrost® slides can
be specially manufactured with customised printings, e.g. name of the
customer, laboratory or hospital. We offer you detailed information about
these specials on request.
Allabove mentioned microscope slides have
hydrophilic surfaces and are commonly used for blood smears.
For research on pathologic and cytologic
samples a different product is needed. Unlike our standard slides these should
have a special “activated” glass surface. In the past it was a lot of extra work
for the laboratory staff to prepare hydrophobic slides e.g. with
protein-glycerine, gelatine or Poly-L-Lysine.
KNITTEL StarFrost® adhesive slides have been
developed by our company especially for pathological and cytological
applications in biological-medical research and diagnostics in order to pick up
cells and tissues easier and at lower cost.
