Standards & Consortiums

RFID for life sciences

Central information page for the implementation of the Cryogenic Radio Frequency Identification system.

Scope

The CryoRFID consortium have been created by EMBL Grenoble Instrumentation group in order to bring together the manufacturers of CryoRFID equipped devices and to centralise the attribution of Manufacturer IDs and Device Type codes. 

The consortium is today composed by the following members: 

  • EMBL 
  • Mitegen 

To join the consortium or to request for the attribution of new Manufacturer IDs and Device Type codes please Contact us.

Technical Information

Programming protocol

The memory of the CryoRFID tag is organized in 52 pages. One page can store 4 bytes (32 bits) and ASCII encoding (4 characters/page) was choosen for the programming of the RFID tags. 

The pages are devided in three main domains

  • Device UID (Page 0 and Page 1)
  • Device Type Code (Page 2)
  • User Field ( Page 3 to Page 51 )
This image has an empty alt attribute; its file name is domains-2.tiff

Device UID

The Device UID has been defined to avoid duplicated IDs between different manufacturers. It is composed of 8 alphanumerical characters. Only six characters are used, the last two being reserved for future extension.

The first letter of the Device UID is the  manufacturer ID. It is attributed according to the Manufacturer Ids table here after. It is up to each manufacturer to follow up on the distribution of the remaining 5 characters, to ensure unique IDs in its production.The Device UID is stored in the memory Pages 0 and 1 of the RFID chip that contain 8 characters in total. Space characters (ASCII character: 32 decimal base, 20 hexadecimal base) should complete the 6 UID characters to reach a total of 8 characters. 

Example for the device UID “AX123A” we have to write “AX123A  ” into the chip.

Device Type Code

The device type allows automated handling systems to recognize a device, e.g. in MX, the different pucks that fit in the same Dewar slot. The device type is stored in the memory page 2 of the RFID chip, which contains 4 characters in total. The currently available device type codes are summerized in the table Device Type Codes.

Example: For an SC3 puck , the code “MX0 “ has to be written to the page 2 of the RFID tag

CryoRFID reader

Description

To help the widespreading of the CryoRFID identification technology the EMBL Grenoble Instrumentation Team has created the easy to use, easy to integrate CryoRFID reader/writer device. This device permits to read and write the cryoresistant RFID tags respecting the above described protocol. There are various accessories to adapt the reader to different device types (a couple of examples on the following pictures). The CryoRFID reader runs a web interface accessible from a simple browser (no software installation required). Furthermore it also runs a low level socket server permitting to integrate it into bigger systems using machine to machine communication.

For more information please contact us. 

Configuration file download

The CryoRFID reader/writer can be updated in order to support new manufacturer IDs ans device type IDs. In order to keep a coherence over these different codes and avoid duplicates, the latest configuration files of the devices are availables exclusively on this website. 

To proceed to the update of your device please download the latest configuration package from the list below and upload it to your CryoRFID reader device

Project History

In 2009 a feasibility study for a new sample holder standard with high sample storage density and precise sample positioning was launched at the EMBL Grenoble. Since 2011 the project has been supported by the European FP7 program BioStruct-X under the name NewPin (http://www.biostruct-x.eu). Led by the EMBL Grenoble outstation the project numbers six synchrotron partners: DLS, ESRF, EMBL@PETRA-III, HZB-BESSY II, the MAX IV Laboratory and SLS. NewPin is also supported by the US synchrotron NSLS-II and by European and American companies active in the field of consumables and robotics (MiTeGen, Molecular Dimensions, Irelec and Arinax).

Two sample holder models named NewPin and miniSPINE were initially proposed. Both allow the storage of 36 samples in pucks with a uni-puck style footprint. A robot gripper that acts as a cold buffer can manipulate both the miniSPINE and NewPin sample holders.

A puck and a robot gripper compatible with the SPINE sample holders (SPINEplus) have also been defined to facilitate the migration from SPINE to miniSPINE and NewPin.

Spines

Initial evaluation of miniSPINE and NewPin was made at the EMBL ESRF/GRG beamline BM14 using a robotic setup based on a six 6 axis industrial robot, a compatible robot gripper and a Dewar (FlexED8: the first member of a fast and flexible sample-changer family for macromolecular crystallography, 2017, Acta Cryst. D73, 841-851 ). 

The miniSPINE model has been selected for the medium scale evaluation of the new standard as it is easier to integrate into beamlines. miniSPINE Evaluation Kits were proposed to evaluate the manual use of the miniSPINE sample holders.

The NewPin model will offer high precision sample positioning and the possibility to increase storage density to 64 pins per puck (fully robotic handling only). The pins will be optionally identified with RFID transponders (under development). The NewPin model will be further evaluated in a second round. 

Details of former developments are available here.

miniSPINE

The standard defines the main dimensions of the sample holder base and associated puck and identification schemes.

miniSPINE sample holder (Pin) base

The miniSPINE Pin base is a 7 mm diameter ferromagnetic support with 1.9 mm diameter gripping area. The basic Pin model is compatible with 0.65 mm diameter cryo-mounts. The dimensions of the Pin base make the miniSPINE Pin compatible with Spine-compatible goniometer setups. See goniometer mounts. The miniSPINE Pin bases can be identified with a Datamatrix ID.

DatamatrixSpinesSampleHolder

Different versions of the miniSPINE Pin base allow:

  • A fixed angular orientation of the base
  • A specific harvesting tool
  • Integrated RFID trarsponders (under development)

miniSPINE Puck

Holds up to 36 miniSPINE Pins. uni-puck style footprint for compatibility with sample changers that accept uni-puck pucks (Requires specific Dewar slots). Compatible with CX100 transport Dewars. Preliminary information (pdf).
