For the cutting of glass capillaries we need special blades of a material that is harder than glass. Usually, a diamond charged blade is used, which is particularly hard.

Zircon oxide blades are an inexpensive alternative that is easy to use. They are also very hard and can be sharpened up at any time.

These blades are particularly suitable for cutting glass capillaries since the flat blade can be drawn over the glass surface with high precision. Afterwards, the capillaries can be separated at the break. This technique also works with extremely fine mark tubes that have a wall thickness of only 0.01 mm.

The blades can be optimally clamped into our aluminium holders and be used freely with one hand only. For your convenience, please consider to add this practical tool to your order.

With this tools you can cut capillaries precisely by yourself.
