Lab Micropipette, Adjustable Volume 8-Channel Multichannel Pipettors

I am a scientist that actively works in the laboratory with my students. I bought this as my first multichannel micropipette for cell culture, cell viability experiments and protein extraction techniques. Was pleasantly surprised on the quality. It mimics well those micropipettes of higher name brands such as Fisher or Eppendorf. I bought both the 300ul and 50ul multichannels from Onilab and both have work very well. It is important to say for those who are interested in the volume increments, that the multichannel for 300ul increases in values of 5ul while the 50ul multichannel goes up in sets of 0.5ul making the latter more accurate for samples. The 300ul is less accurate due to the 5ul increments but works very well for what I use it for in my experiments. The multichannel has gone through some rough handling by 4 of my students in the laboratory plus myself and still going strong. Would recommend if top brand names is not a concern for you, although Onilab tends to make good products from my personal experience. Also, I tested the compatibility with different micropipette tips and they fit perfectly well with 200ul micropipette tips from brand names such as Fisher and Sigma and from 200ul micropipette tips that you may find throughout Amazon. Needless to say, they are compatible with Onilab’s pipette tips.

Ha tenido poco uso, son de buen material y por ahora no han fallado, quizas necesiten calibrarse para trabajos mas precisos pero para un manejo en laboratorio de enseñanza estan bien.
