When vortexing small volumes (microcentrifuge tubes), this thing is perfect. It takes up nearly no bench top space and allows me to rapidly mix a sample in no time by simply holding it down on top. We have about six of these and have never had one break in the years we have been using them. read more

We have several of these in lab and use them very routinely for solution making. The thermostat function is very fast acting, however we only use this mode in low temperatures. Overall, these have held up well in the lab. read more

We had bought four of these and used them somewhat frequently in routine procedures. However, after around a year, one had an issue where the lid had to manually be held down to operate. Shortly after, the rotor on another stopped operating. While the other two still work, we expected more shelf-... read more

We have a very big collection of this line of pipettes, ranging from 2 uL to 1000 uL. We have had multiple people using these for over four years and they still consistently pass precision and accuracy tests. I feel very confident in these and have never had issues with inaccuracies. read more

I use these filters in the process of plant matter extractions before MS applications and find that they are essential for the cleaning and extraction process. I don't ever have issues with any tearing or inconsistencies. read more
