The TwisTorr 305-IC turbomolecular pump with integrated controller features a revolutionary design and smart connectivity through near-field communication (NFC).
This 300 L/s turbo pump communicates seamlessly with the Vacuum Link app.
Due to its compact form factor and small size, the TwisTorr 305-IC is ideal for use in any instrument and any industrial application requiring a high compression ratio and low vibration.
