Options available to enhance the utility ofyour system with customisable features for
specific applications.

Sample pucks for rapid exchange
Our patented, market leading sample loading mechanism allows
for fast and easy sample exchange, without the need to warm
the entire system to room temperature:- Loading a sample puck takes less than 15 minutes and thesystem automatically cools back to base temperature- Up to 28 RF and 96 DC connections on a single sample puck
- Ideal solution for multi-user facilities since different experiments
can be prepared in multiple sample pucks- Patented loading concept allows for safe and easy operation.

SampleProtect system secures against ESD
SampleProtect enables grounding or bias of samples during
sample exchange to safeguard your experiments. It provides
users with a method of protecting sensitive samples from
accidental electrostatic discharge (ESD).
High quality, fully earthed cables for low level signals:- Low noise- High attenuation shielding- Low cross-talk.
BNC or Twinax option.
24 connectors and 12 twisted pairs.
