This variable-volume microdispenser is engineered to overcome sample delivery problems associated with DNA sequencing techniques.

• Volume range: 0.25 to 3 µl
• Non-contact plunger and replaceable autoclavable tips
• First variable volume microdispenser designed for DNA sequencing operations
• Spring-loaded override
• Replaceable polycarbonate bore

Calibrated plunger assembly dispenses preset volumes from 0.25 to 3 µl range with increments at 0.05 µl. A spring-loaded override provides for blow out.

The unit features a replaceable polycarbonate bore with 0.34 mm (0.014") Ext.Ø tip that provides precise microliter delivery from 0.25 to 3.0 µl. It dispenses volumes as small as 0.25 µl into narrow (0.35 and 0.2 mm) gel slots.
