DKI 720 glass capillary Needle/Pipette Puller (Single Stage)

The Model 720 Needle/Pipette Puller (Single Stage) is the ideal instrument for the busy laboratory where a number of pipettes are required. This unit is easy to use, versatile and a reliable vertical pipette puller with excellent repeatability.
Controllable parameters include heater voltage, solenoid current and length of gravity fall. These parameters coupled with heater configuration allow a wide variety of pipettes to be pulled.
Large tips as well as tips of 0.25 microns or less can be obtained. Pipette glass diameters of 0.4 mm to 3.0 mm, thin as well as heavy walled, can be held and pulled.
The unit pulls pipettes vertically to help assure straight, concentric shapes. In addition, its small, compact size (11″ x 9-1/2″ x 14-1/2″) occupies less than a square foot of bench space. Like all Kopf instruments, the Model 720 is built for reliability and durability and requires little maintenance. The slide mechanism employed is a super accurate component that has been used for more than 35 years on other Kopf vertical pipette puller.
