Used Lab Equipment

The VK 7000 is designed with automation and flexibility in mind. These microprocessor-controlled instruments allow for easy manual sampling as well as direct interface with the VK 8000 Dissolution Sampling Station. The EaseAlign system for centering vessels allows the use of a variety of vessel sizes (with options of 100 mL, 200 mL, 1L (standard), and 2L and 4L vessels). These units are preconfigured to accept accessory upgrades. VK 7000 units can be fitted with a number of options including AutoTemp and Dosage Delivery capabilities. This model is easily adapted to interface directly to a variety of UV or LC systems.
