GRIPTIPS : Perfecting the connection between pipette and tip
Reliable tip sealing
and firm tip attachment are of key importance for efficient pipetting. With this in mind,
we have re-engineered the connection between pipette and tip. By designing the GripTips in tandem with the
new Tri-lobe tip fitting we have created a unique and fully integrated system.
Your
benefits with the new GripTips and VIAFLO pipettes:
- GripTips will latch onto the pipette. Never lose a tip again - even when touching off (tip touch).
- On a VIAFLO
multichannel pipette, all tips sit on the same height to allow accurate
touch-offs.
- Perfect fitting and sealing between tip and pipette for best accuracy and precision results.
- Attachment and ejection forces are among the lowest on the market, which helps to prevent repetitive stress injuries.
The
Tri-Lobe tip fitting explained
3 lobes are arranged
in pyramidal shape. GripTips will snap over this
lobes, attaching firmly. As a result, GripTips will never accidently fall off, even after several touch-offs (tip touch).
A shoulder provides a
positive stop to prevent over-tightening of the tip. It can only be attached up
to that point and no further. That means, the tip is either on or off, but
nothing in between. Hammering the pipette into the tips to make sure they attach
correctly is no longer required.
The O-ring on larger
volume pipettes provides a forgiving and robust seal.
GripTips are designed for the
Tri-lobe tip fitting. Their features perfectly match the tip fitting to form a
complete system.
Why
generic pipette tips are falling off and GripTips don’t
Most tips are made from plastic material called polypropylene. This material has excellent chemical resistance properties but has a memory effect in terms of shape. When a generic tip is attached to a pipette with a conical tip fitting, the tip shaft is widened. Due to the memory effect of polypropylene, the tip will slowly go back to its original shape and thus fall off. A touch-off (tip touch), which is generally performed after a pipetting step, will increase this issue because it wiggles the tip off.
The unique design of the Tri-lobe tip fitting and GripTips takes advantage of the memory effect. The shape of the tip shaft is altered only briefly and springs back to its original shape once it has snapped on the lobes of the tip fitting and thus prevents GripTips from falling off.
