All parameters given below can be changed according to the specifications of the customers without any surcharge. The meanings of the parameters can be taken from the drawing.

Glass:
The needles are manufactured from borosilicate glass capillaries. The ends are firepolished in order to protect the washers of the capillary holders.

Inner diameter (ID):
The standard ID is 25 µm. In this range there are no differences in the holding properties of the pipettes. Smaller diameters have the disadvantage of easy clogging.

Straight and bent holding pipettes:
Holding needles with straight or bent tips are delivered.
