Glass Microscope Slides

Premier quality Micro-Tec glass microscope slides are made from optically clear and corrosion resistant select quality soda lime glass. All slides comprise precision ground edges are are pre-cleaned. This low iron soda lime glass has no notable interference from UV light in the 250-350nm range. Currently available slides are:

  • standard plain slides, 75 x 25mm, with precision ground edges,
  • large plain slides, 76 x 51mm, with precision ground edges.
  • concavity slides ,76 x 25mm, with optically clear single well or double wells. Ideal for liquid samples and tissue cultures. Well size is 15mm diameter and 0.5-0.55mm deep.
