Core components
Simple sample preparation and automatic transfer
The L-Type Rapid works with a puck-based system, letting you prepare experiments outside the cryostat while measurements are running. Using the Puck Station, check DC and RF connections at room temperature and take a reference measurement, then transfer the puck to the Automatic Sample Loader via the Puck Transfer Cage. From there, the instrument software automates loading and cooling, limiting physical interaction with the cryostat to just a few minutes – including airlock evacuation and transfer to the millikelvin stage, the full process takes less than 10 minutes.
Once loaded, cooldown happens automatically, and samples can be unloaded at any time regardless of cryostat temperature. After unloading, warm the puck in an inert gas environment to prevent condensation.
Unloading and warm-up take around 30 minutes. The system is ready for the next run within 40 minutes of handling time.

Configure the L-Type Rapid to your needs
Magnetic shielding
Layers of mu-metal and superconducting shields suppress the magnetic background at the sample position, ideal for characterizing sensitive superconducting devices such as resonators and qubits.
Sample magnet
Integrate a sample magnet at the sample position: 5 T or 8 T solenoid magnets, or a 3 – 1 – 1 T vector magnet.
Flexible sample packaging
Various commercial sample holders fit your puck, including probe cards, cryo-prober, QBoard and QCage by Quantum Machines, and Linqer – so you can speed up and optimize measurements of sensitive quantum devices.

Extend standard DC lines with semi-rigid RF cables rated to 18 GHz, with customer-specific attenuation for each line. Configure wiring trees with low-noise amplifiers, isolators, low pass filters, and couplers to match your characterization needs.
Intuitive graphical user interface
kiutra.io offers pre-configured control functions through a modern, graphical user interface. It ensures intuitive and fast access of all core features of the cryostat, such as temperature control, sample magnet, and the automatic sample loader.
Browser-based operation
The software runs from your browser on a PC, laptop, tablet, or any other device with a network connection. This ensures maximum flexibility in everyday use, while ruling out compatibility issues with different operating systems in your setup.
System health monitor and live data
Real-time updates on important parameters minimize errors and downtime. Live plots help you monitor your cryostat and measurements in real time, keeping you in control throughout the experiment at any time.
Touch optimized
An iPad mounted directly on the cryostat runs a touch-optimized version of the instrument control software. Monitor key parameters and initiate essential processes right at the system, freeing up lab space and eliminating the need for dedicated measurement PCs.
Guided user interface
Step-by-step instructions help both experienced and inexperienced users navigate the system and perform tasks with ease.
Seamless integration with Python
An integrated jupyter lab environment lets you automate processes, execute scripts and customize routines – all directly from the user interface.

Put the L-Type Rapid to work
You don't need a system of your own to get started. Send us your samples and we'll run the measurements for you, or book time on our system to run them yourself – a low-commitment way to see the results before investing.
Measurement as a Service
Send your samples and we run the measurements, then return the data to you.

FAQ
Will magnetic cooling expose my sample to harmful stray fields?
Our cryostat design mitigates magnetic fields to protect sensitive materials and devices. It uses compensated superconducting magnets and maximizes the distance between the sample stage and cooling units. Stray fields at the sample position remain below 50 µT – about the strength of the Earth's magnetic field – even when all magnets are fully powered.
Can I get ESD protection?
Yes, the system can be configured with ESD protection. Get in touch for setup details.
Does the L-Type Rapid provide continuous cooling?
Yes, depending on the configuration: continuous cooling is provided above 100 mK with 3-stage ADR, or above 200 mK with 2-stage ADR. Full spec sheet here.
What do you mean by turnaround time?
It's the time between measurements on separately loaded samples: unloading (~5 min), warming up (~30 min), loading (~5 min), and cooling down (2–4.5 hours, depending on configuration). Total: around 40 minutes of handling plus 2–4.5 hours of cooldown.
Can I get magnetic shielding?
Yes, we can integrate magnetic shielding both on the system level and on the puck itself. This reduces the residual field by two orders of magnitude. Get in touch for integration details.
Can I customize the system?
Yes, it's highly customizable. See options or contact us to configure.
Can I upgrade to a different configuration after delivery?
Yes. Our cryostats are designed to accommodate future upgrades. Get in touch to discuss options.
Can I get a sample magnet?
Yes. We can integrate 5 T or 8 T solenoid magnets, or a 3 – 1 – 1 T vector magnet. Get in touch to discuss options.
How large is the sample space?
Puck 55: 55 mm in diameter and 117 mm in height. Download the data sheet.
Is there space to integrate RF electronics?
Yes, in addition to the sample space on the puck, there is ample room to integrate cryogenic electronic components at the 4 K stage and on the sample stage. Get in touch to discuss.
What wiring is included in the system?
The system is equipped with DC lines. It can be configured with RF wiring and RF electronics during the assembly. See options.
Is there a full system manual available?
Yes, there is. Get in touch if you are interested in getting a copy.
Can I measure qubits?
Yes. See how we measured T1 times in superconducting qubits in this application note.
Does the cryostat need regular maintenance?
The cryostat itself does not. The compressor requires maintenance every 30,000 operating hours, and the coldhead after 20,000 hours.
Do you have a support line?
Yes. You can reach the team here: Phone: +49 89 35647977-0. Email: support@kiutra.com. Or through the cryostat control software GUI.
Can I see a demo?
Yes, get in touch to book a demo with our team.
Do you offer service contracts?
Yes, we offer service contracts covering wearing parts during the warranty period and beyond.
Do you offer staff training?
Yes, we offer both remote and in-person training.
