With these syringes for GL, LC, TLC and biochemistry the entire sample volume is accommodated in the cannula. The tungsten piston extends to the tip of the cannula, i.e. 100% of the sample volume is used. Can be used against high counter-pressures and in dispensers.
Round to 90°, e.g. for applying specimens to TLC plates.
The cannula tip is ground to 10 – 12° and bent slightly inward in order to pierce a septa.
