HT4000A is HTA sample preparation workstation that allows automation of sample preparation procedures by taking care of a large number of operations such as liquid handling, purification or filtration, tracking and further sample processing such as vortex, automatic uncap/ recap, and weigh. This video focus on automatic uncap/recap function of HT4000A. Automatic uncap/recap is particularly useful when samples or solvents are volatile. In such cases septum piercing is not recommended because a sample loss can occur, especially if samples remain long time in the workstation; therefore it is more advisable to uncap the sample vessels, perform liquid handling tasks, and then immediately recap. In this video we show: • Sample vial displacement • Screw cap decapping • Screw cap recapping
