Excellent Shaker

This instrument was life saver for me during my cloning experimentation days. I used this machine almost every day, for my gene cloning experiments. I was used to keeping my tubes overnight in this shaker and I had no issues regarding to its functionality. The instrument never broke down in between of the shaking cycle and it shakes the tube and solution so well that every time the growth of my bacterial culture was high. Instead of a drawback, I have a suggestion/recommendation for this instrument. The manufacturers should provide some supporting system with this machine as we camp up to put balance when we used small tubes for shaking, as the instrument was not having it. You can see in the product picture that we used the balance/support for the tube shaking.
