Vivaspin® 100 PES Centrifugal Concentrator, 2 pc

Vivaspin^® 100 PES centrifugal concentrators are designed for the concentration or diafiltration of samples up to 98 mL. These devices combine the ease of use of centrifugal devices with further flexibility and control provided by pressurized operation.

Easy to Assemble

Vivaspin^® 100 devices were specially designed with ease of handling and efficiency in mind. The devices are easy to assemble, require no tubing connections or stirring mechanisms and can be adapted to equipment availability or specific user preferences.

Flexibility in Process

Vivaspin^® 100 PES centrifugal concentrators are unique in that they provide the experimenter with a choice between centrifugal, pressure or pressure-shake operating methods. For example, for increased process control, gas pressure can be combined with gentle orbital shaking.

Highest Sample Capacity

Fitting swing bucket rotors accepting 250 mL bottles, Vivaspin^® 100 offers the highest sample capacity available in a centrifugal device: up to 90 mL.

Use for Single or Sensitive Samples

Vivaspin^® 100 can also be used for single or extremely sensitive samples of up to 98 mL when pressurized. Moreover, temperature-sensitive samples can be placed into a refrigerator while the device is pressurized. The unique design ensures pressurization is easy, by using quick-release connectors. This method can be combined with orbital shaking for an even faster sample concentration.

Simplicity of Use

For your convenience, these devices are simply spun in a large capacity centrifuge (carriers accepting 250 mL bottles). For the highest simplicity of use with minimum equipment requirements, Vivaspin^® 100 can be pressurized on a laboratory benchtop or in a refrigerator.

Vertical Membrane Design

Regardless of the model used, the vertical membranes in Vivaspin^® 100 inhibit and minimize fouling. Further, the integral dead-stop of 350 µL ensures the highest concentration factors, while impeding concentration to dryness and loss of sample.
