Some syringe pump characteristics

How would you like if your new syringe pump pumps like this? Here a 60 ml syringe with a rubber based plunger sealing is set to pump 15 ml/h. It takes 4 hours to empty the syringe. The set-up is degassed and has no compliance in the tubing, which otherwise would dampen the flow pulsations. [...]

Effectiveness oil based evaporation cover

DTI has evaluated the effectiveness of the oil based evaporation cover to lower than 5000 times compared to uncovered. At this evaporation rate it would take thousands of year for a simple glass of water to evaporate. But the twist is that it actually would gain in weight instead, from the amount of dust and [...]
