Mechanical Pipettes
CAPPAero multichannel pipette has a unique construction, ensuring extremely easy tip mounting and ejection. Both the 8- and 12-channel pipettes have an external ejection lever, assuring ergonomic and effortless tip ejection. This unique construction of CAPP multichannel pipettes enables the thumb to rest under tip ejection and helps to activate the other fingers, considerably reducing the thumb workload. Tip ejection is simply a matter of applying light pressure to the levered ejector arm. Excessive thumb workload by multichannel pipetting is one of the major causes of repetitive strain injuries and user discomfort. Apart from the external ejection lever, the lower part of each 12- and 8-channel pipette is slightly bent in order to eject only 2 tips at a time! This happens so smoothly, as if all 8 or 12 tips were ejected in one take, but this special construction of the lower part distributes the pressure and minimizes the workload. Each tip cone of CAPP multichannel pipettes is made of anodized aluminum and has double O-rings, which all together eliminate the need to ‘hammer’ the pipette into the tips rack to secure the optimal tip mounting. The ‘hammering’ is quite a common issue by multichannel pipetting with many other brands. With CAPP multichannel pipette you only need to apply a slight even pressure to perfectly attach the tips to the nose cones.
