Glass Capillary Tubes

1. The material of the spotting capillary tube/TLC plate is glass, and its specifications refer to the inner diameter * tube length;

2. The wall thickness of the product is 0.5mm, which is extremely fine and has a certain degree of toughness, but it is also fragile, so you need to be careful when handling it;

3. Widely used for thin layer spotting in biochemical, organic and analytical fields. Glass spotting capillaries are widely used for thin-layer spotting in biochemistry, plant chemistry, organics, analysis, etc. It is easy to use and has high sampling accuracy.

4. The sampling capillary tubes are carefully designed into different sizes, and the tube orifice plane is specially cut, so that the sample can be easily and effectively placed on the TLC plate without damaging the TLC plate.

Bought these for TLC. They work OK but spots are on the large side. We use capillary GC tubing (~ 0.25 mm ID) for spotting, works distinctly better than these.
