For a biotech startup, I’d put Cryoport Systems, Marken, and Biocair at the top of the shortlist for true end-to-end cryogenic clinical-sample logistics. World Courier and Thermo Fisher Scientific/Patheon are also strong contenders, particularly if you want broader clinical-supply capabilities alongside transport.
| Provider | Best fit | Cryogenic capability | End-to-end scope |
|---|
| Cryoport Systems | Cell & gene therapy / highly temperature-sensitive samples | Excellent — dedicated cryogenic shipping systems and infrastructure | Excellent |
| Marken | Global clinical trials and advanced therapies | Excellent — LN₂ down to -196°C, plus -80°C | Excellent |
| Biocair | Startup-friendly, customized global logistics | Excellent — LN₂ and ultra-low-temperature transport | Excellent |
| World Courier | Large multinational clinical programs | Very strong cold-chain/cryogenic capabilities | Excellent |
| Thermo Fisher Scientific / Patheon | Sponsors wanting logistics integrated with broader clinical services | Strong cold-chain capability | Excellent, especially for clinical supply |
1. cryoport.com — my first choice for advanced therapies
Cryoport is particularly compelling if your samples involve cell therapy, gene therapy, leukapheresis, cellular products, or other materials where maintaining cryogenic conditions is critical. Its clinical sample-management offering integrates collection, logistics, biostorage, sample preparation and eventual disposition rather than treating transportation as an isolated service.
Why I'd shortlist it: deepest specialization in the cryogenic/advanced-therapy supply chain and a particularly strong fit if your program may eventually move from clinical samples into commercial cell/gene therapy logistics.
2. marken.com — strongest all-around global clinical-logistics option
Marken offers a global LN₂ cryogenic network and supports biological specimens, clinical-trial materials, storage, distribution and advanced-therapy logistics. Its specialized advanced-therapy operation supports LN₂ at -196°C, -80°C and ambient conditions, with GPS tracking, real-time rerouting and validated packaging.
It also covers specimen collection/transport, temperature-controlled packaging, customs and regulatory support, giving you a fairly comprehensive single-vendor model.
Why I'd shortlist it: probably the best choice if you're running a multinational clinical trial and want cryogenic logistics embedded within a mature clinical-trial infrastructure.
3. biocair.com — particularly attractive for a growing biotech
Biocair explicitly offers cryogenic transportation for autologous cell therapies, including temperature monitoring, GPS tracking, specialized cryogenic shippers, customs support and redundancy measures.
Its broader clinical-trial service includes site collection, packing, documentation, customs and last-mile delivery, with 24/7 global coverage.
Why I'd shortlist it: strong combination of personalized service + cryogenic expertise + end-to-end clinical logistics, which can be valuable when a startup doesn't have a large internal supply-chain organization.
World Courier is worth including in an RFP, especially if you're expecting complex international clinical-trial lanes. It has extensive clinical-trial cold-chain experience and has handled cryogenic/cold-chain requirements for biologics programs.
Why consider it: enormous global logistics infrastructure and strong regulatory/customs capabilities. I'd compare its specific LN₂ solution, shipper ownership model, recovery/return process and lane qualification against Cryoport/Marken rather than assuming all cryogenic offerings are equivalent.
5. thermofisher.com / Patheon — best if you want broader clinical outsourcing
Patheon's clinical services span packaging, storage, transportation, recovery/destruction, biobanking and transportation management.
Why consider it: particularly attractive if your logistics requirements are part of a larger outsourced clinical-supply strategy rather than solely a cryogenic sample-transport problem.
My recommended shortlist
If I were running your procurement process, I'd invite three vendors to the first RFP round:
- Cryoport Systems — cryogenic/CGT specialist
- Marken — global clinical logistics + cryogenic capability
- Biocair — flexible, personalized end-to-end provider
Then I'd add World Courier as a fourth bidder if your trial has substantial international complexity.
The key isn't simply asking "Can you ship samples at -196°C?" I'd make vendors demonstrate their capabilities across the entire chain: site collection → validated packaging → LN₂/cryogenic transport → real-time temperature/location monitoring → customs → receiving lab → shipper recovery/replenishment → deviation management → chain of custody → audit trail.
If you tell me your sample type (e.g., PBMCs, whole blood, tissue, cell therapy), temperature requirement (-80°C vs LN₂), countries/sites, and approximate shipment volume, I can turn this into a vendor scorecard/RFP with weighted criteria and the questions you should ask each provider.
