Designed for high-density cryogenic testing, it brings 48 individual DC channels through a single KF40 port, enabling more connections and more devices under test without a large breakout assembly extending into the experimental volume.

Small Coldfinger is a compact, modular sample-holder solution designed for millikelvin environments. Made from high-purity copper with non-magnetic gold plating, it features two layers of magnetic shielding, flexible mounting options, and compatibility with a wide range of sample holders and dilution refrigerators. Custom configurations are also available for different sample sizes, shielding, and mechanical interfaces.

Nord Cryo offers RF Cables that are in production use in tens of quantum computers worldwide.

Nord Cryo is proud to support Syracuse University and Assistant Professor Ethan Arnault’s team in quantum research, providing cryogenic electronics, mechanics, and customized hardware for demanding low-temperature environments.

Nord Cryo is honored to support the Low Dimensional Electronics research group at the Max Planck Institute for Solid State Research with cryogenic hardware for advanced low-temperature quantum research.

Nord Cryo is proud to support Groove Quantum with cryogenic products and expertise for demanding quantum systems. Groove Quantum is developing germanium qubit technology with a focus on scalability and semiconductor-compatible manufacturing.

Nord Cryo Line cables are now available for both room-temperature use and use inside the cryostat. Tested and validated by a team with hands-on experience in scaling production-grade quantum systems.

Nord Cryo offers cryogenic sample holders for QPUs with tens of qubits, with support for 100+ qubits coming next. Built on hands-on experience in scaling production-grade quantum systems, we help customers solve cryogenic infrastructure bottlenecks.

We have designed a microD25 to 24 SMP adapter. Enclosure Au-plated copper. M3 mounting holes at the sides. Ask for different gender, orientation, rf connector, shape or any other feature.

We provide Au-plated copper mounting brackets in three different sizes. Please see our brochure

We designed and manufactured cryogenic RC filter using large 940 nF capacitors. These models are available for both pairwise (PW) and ground-referenced (G2) two-stage filters.

An 8-channel 2-stage RC-filter was designed and built. Size 50 mm x 100 mm x 8 mm.

A) Breakout box with BNC, individual RC filtering and grounding options. B) Breakout box with SMA connectors, two selectable RC filter options (F1/F2) and grounding switch

We have built a BNC breakout for Fischer-24 pin connector with selectable RC filters. The filter takes place between pairs of twisted pair lines (1-2, 3-4, ). It is possible to disable filtering if needed.

We design and manufacture Micro-D25 adapters to various connector types (SMA, SMP, MCX, nano-D etc) or for direct soldering. The adapters can be single block units with all input/output connectors in single enclosure or combinations of micro-D connector, shielded cable and output connector enclosure. Aluminum enclosure as standard, Au-plated copper upon request.

Simple and slim 19-inch wide and 1U high aluminum panel with 40 SMA feedthru connectors. We can also modify panel to house different connectors according to your needs.

We have introduced new Therma filter models with more versions and improved EMI shielding. Please take a look at the Therma (cryogenic RC filters) pages.

We have designed and manufactured cryogenic and non-magnetic sample holder with three rf connectors (SMP) and multi-pin dc connector (Omnetics, 21 lines). The design work was made in collaboration with e-Si-AMP consortium consisting of leading metrology institutes (www.e-si-amp.eu). The holder has duplicate dc connector for grounding. This makes it possible to transport sensitive samples between Read more about Exchangeable sample holder for electron pump devices[ ]

We have updated the earlier BattSwitch and added automatic swapping every 12, 24 or 48 hours. By moving chargers outside the unit, the newest design is capable of producing four uninterruptible voltages. Thus, one can e.g. build up to +/-24 V regulated voltage supply. Preliminary manual available here.

Upon customer s request, we designed and built a small sampleholder with non-magnetic SMP connectors. The size of the gold-plated copper or aluminum holder is 30 mm x 30 mm. It is easy to customize this design to fit different number of connectors or other features.

We have designed and build a battery swapping electronics BattSwitch that is based on our earlier uninterruptible battery source. BattSwitch can swap between 1-6 battery pairs and in addition it can contain linear voltage regulators to provide a stable and constant uninterruptible voltage supply for e.g. preamplifiers. Swapping can be controlled both manually and user-specified Read more about Battery swap unit[ ]

We have designed and built an eternal battery power supply unit (PSU). In this 8-channel uninterruptible PSU, each output channel contains two batteries and a charger. One of the batteries is connected to actual output and the other is being charged. An intelligent relay electronics swaps the batteries within few milliseconds and a large capacitor Read more about Uninterruptible battery power supply[ ]

Analog isolation amplifier based on Burr-Brown IC. Please see manual.

Sampleholders for RF measurements. Gold-plated copper.
