SCILOGEX Pipette Controllers are a syringe-style pipetting device, for easy, one-hand control of filling and delivery for (TD) pipettes; that are calibrated to the tip but not to be blown out (retains final drop). For rapid delivery, the rapid release lever can be depressed directly and for finer filling/dispenses, the thumb wheel is rotated. A tapered plastic chuck grips the end of pipette. The controller can be easily disassembled for cleaning. Offered in 3 color-coded sizes, for 2ml, 10ml and 25ml maximum capacities.
