Eppendorf - Refurbished Pipettes Research Plus, 8-channel MuLtichannel Pipette Variable, 10 - 100 uL Product Description: The Eppendorf Research Plus Multichannel Pipette combines the spring-loaded tip cone, a secondary calibration option and improved volume display all in an ultra-light, fully autoclavable pipette. The spring-loaded tip cone saves your energy and time. No need for rocking, the spring guarantees a reproducible and safe tip fit. It provides increased user to user reproducibility for more uniform results among members of the lab. Eppendorf Research Plus Multichannel Pipette features and benefits: Air-displacement pipette for accurate pipetting of aqueous solutions. Feel the difference in weight and pipetting forces: the ultra-light mechanical pipette is designed according to the strict criteria of the Eppendorf PhysioCare Concept and limits the strain on your hand and arm. Spring-loaded tip cone for minimal tip attachment forces helps to reduce stress. The low tip ejection force can be as low as 3.6 N. Adjust your pipette in seconds for better accuracy when pipetting various difficult liquids like ethanol or even when pipetting at high altitudes. Return to factory adjustment without calibration. Autoclave the entire pipette or only the lower part according to your needs to ensure decontamination. Enjoy excellent flexibility and choice of variable volume 8 and 12 channel pipettes. Applications: Forward pipetting. Reverse pipetting. Removal of supernatants. Sample mixing. Phase extraction. Filling of plates, gels, and reaction vessels. Model Test Tip epT.I.P.S.
