microsampling designed with the lab in mind

Powered by VAMS^® technology, the patented Mitra^® Microsampling Device offers a streamlined approach to biological specimen collection, transport, and preparation. Use Mitra to facilitate sampling direct from animals, humans, or tubes to collect precise, reliable dried microsamples compatible with a wide variety of downstream applications as evidenced by the hundreds of published peer-reviewed manuscripts and the millions of devices that have been used in the field.

Mitra: pioneering VAMS technology

Trajan’s proprietary VAMS^® Technology is at the heart of the Mitra device, featuring a sampler tip crafted from a porous, hydrophilic polymeric material. This 'precision sponge' rapidly and consistently absorbs a specific volume of biological fluid—simply by contacting the source. The fluid is then allowed to dry acting as a stabilizer for most analytes.

Available in three tip sizes—10, 20, and 30 µL— and multiple formats, Mitra devices meet diverse end-user and analytical needs. Configurations include dual (2) or quad (4) samplers across various formats. Collect from 20 µL to 120 µL per device based on format selected. Our team of expert microsampling consultants is on hand to provide scientific support, helping you choose the optimal format and workflow for your specific applications.

Reliable

Quantitative sampling with pipette-like precision (RSD ≤ 5%). VAMS eliminates traditional blood hematocrit biases and results in extremely low in-lab sample rejection rates. No glue used in assembly, no matrix interferences.

Versatile

Collect biological fluids—blood, plasma, urine, saliva, and even tears—efficiently from humans and animals (e.g., finger, arm, knee, tail, etc.) or containers. Manual to fully automated workflows are available.

User-Friendly

99% sample acceptance rate validated by studies. VAMS tip acts as a fill indicator to confirm successful sampling. Outer housing protects against contamination and facilitates easy remote or home sampling.

Cost-Effective

Eliminate phlebotomy, couriers, and cold-chain shipping / storage requirements. Devices are compatible with standard automated liquid handling systems and available in various formats to suit different budgets.

mitra-collection-kit_v3 The Specimen Bag Mitra format is perfect for those looking to create their own collection kits for remote sampling or maintain bulk devices for centralized sampling in clinical or field settings.

Each Specimen Bag is sealed and includes a barcoded Mitra device with a unique identifier and desiccant. After collection, the device is placed back into the Specimen Bag to facilitate quick drying and protect the sample from external contamination.

If you need logistics help, bioanalytical lab services, or kitting support, we can connect you with experienced organizations that specialize in microsampling.

Regulatory status: Mitra® devices are CE-IVD (IVDR) devices intended as a specimen collector, and for the storage and transport of blood and other biological fluids for analytical and diagnostic analyses. They are available as registered IVD Devices in the European Union and United Kingdom, Australia, Brazil, China, and Canada, as well as multiple Health Ministries worldwide. In the USA, Mitra devices are supplied as a research use only (RUO) product to assist in method development, other research-related and non-diagnostic activities. End-users and laboratories must validate the use of the Mitra devices for the particular diagnostic testing intended.

Our Instructions For Use are available in English, German, Danish, Spanish, French, Italian, Dutch, Norwegian, Polish, Japanese, Vietnamese and Portuguese. Need a different language? No problem—just reach out to us at neo.support@trajanscimed.com, and we’ll be happy to assist!

The Microsample Collection Kit Mitra format streamlines the blood microsampling process, enabling both assisted and self-collection at home or in the field. Each kit is equipped with device, barcoding for secure chain of custody, easy-to-follow instructions, all necessary finger-prick sampling supplies, and a return-mailing envelope, all packaged for global distribution. Ideal for remote blood collection, these kits ensure that samples can be directly sent to accredited labs for precise analysis.

For customization to meet the demands of large-scale projects or to optimize your workflows and logistics, please consult with our Microsampling Consultants. They will provide tailored recommendations to align with your project’s specific objectives.
