SEPARA? Syringeless filter is one step sample preparation device and integrates a device auto-sampler, filtration membrane, plug and cap/septa. The device consists of two parts: an internal vial with a membrane chamber and an external vial to be filled with filtrate. The internal vial has a sealed membrane and a cap with a pre-cut septa.
The liquid is placed in the external vial and dispensed by pressing the internal vial. This pushes the liquid through the membrane. The sample is then filtered and the SEPARA is ready to be loaded in the auto-sampler.
Features:
Save money – Eliminate the need for separate syringes, syringe filters, vials and septa, reducing sample preparation costs by 50%
Save operator time – 15 seconds SEPARA? Press&Go!, against 3 minutes with conventional sample preparation methods
Speed up process with high throughput automation – Designed and compatible for use with all HPLC or UHPLC auto-samplers
Preserve precious samples – Start with less sample volume; dead volume as low as 30 microliters (μL)
Reduce risk of cross-contaminations – No cumbersome steps transferring sample between different devices
Extend column life and needle longevity – Reduce risks of clogging and back pressure build up
Increase operator security – Safer single step process
Reduce identification errors – Color-coded caps by membrane type and pore size
