Manual Liquid Handling - John Morris Scientific

Ultra Accuracy
and Precision
Improved comfort when
fitting and ejecting tips
Exclusive G-F.I.T. System provides instant reliable
seals and low ejection forces for Pipetman Ultra
and Pipetman Concept Large Volume (U5000; U10mL)
and Multichannel models. G-F.I.T. System is compatible
with most standard tips.
Exclusive patented
multifunctional
electronic liquid crystal
display with greater
readability and zero risk
of parallax errors.
The force required to fit and eject Diamond tips using
the G-F.I.T. System can be reduced by as much as
half of that of regular tip-holders. Above 40 N, the
ejection force remains at a steady level around 17 N
(example for Pipetman Concept Multichannel 12x300).

Stop & Guide
Ultra comfort
in daily use
Ergonomic design fits naturally
in your hand and requires less effort
to use.
Less force is needed to pipette
for a smoother pipetting on a daily
basis.
Quick volume setting
Only ten turns are needed to change
from the minimum to the nominal
volume setting.
Easy volume adjustment
The thumbwheel’s rotating friction
forces are reduced to a minimum.
Natural movement
Three-position tip-ejector button
(patented) may be set for left- or
right-handed users providing a
natural accessibility.
The lateral position of the button
respects the hand’s anatomy,
requiring less force to eject the tips.

G-F.I.T. System
Adjustable patented tip-ejector works as a stop-block
preventing over-insertion of the tip-holder into the tip
(all models except U10mL).
Maximum compatibility. The position of the tip-ejector
can be adjusted to adapt most standard tips.
