Protasis CapNMR probes can be loaded conveniently from a standard 25 or 50 microliter syringe into a simple injection port built into a microvolume union. This can be done by hand. But the Protasis Manual Injection Module (aka MIM) provides a convenient stand to hold the syringe, the injection port, an in-line filter and the connection to a small diemeter (100um) transfer line. Many samples are small enough to simply push to waster. But the MIM also holds a small vial that can be used o recollect your 'precious' sample from an optional 'sample return' line.
