Like the single channel PIPETMAN L, the Multichannel version also offers an extremely lightweight pipette, that has been designed to fit naturally in your hand. Its new shape ensures a perfect fit while the new hook reduces tensions while holding it. An adjustable tip ejector button has also been implemented to adapt to both right- and left-handed users. Either push the tip ejector button with the tip of your thumb (figure one) or with the base of your thumb (figure 2), making it more comfortable and easier to access for any size hand.
