Knowledge Hub · µ DDS-A™
A modern cyclotron radiopharmacy can\'t cancel patient PET slots because automation is being serviced. µ DDS-A is the plug-and-play dose drawing module that keeps F-18 unit-dose production flowing in those windows. Drops into any laminar-flow hot cell with a dose calibrator. Shielded syringes out. Manual backup mode built in. 274 units worldwide.

Why this matters
Redundancy for F-18 dispensing
PET imaging volumes are appointment-driven — when the primary dispenser is down, patient slots don't wait. µ DDS-A is the redundancy layer that lets the cyclotron radiopharmacy complete the F-18 unit-dose workflow even when CRP / FLEX automation is being serviced.
Based on: Saxsons-supplied market positioning for Indian cyclotron sites
Read source ↗Plug-and-play install
Adding backup capacity normally means commissioning a second shielded cell — a major capital decision. µ DDS-A is engineered as a stand-alone module that installs in whichever shielded cell already has a dose calibrator. Backup capacity without doubling the shielded footprint.
Based on: µ DDS-A product page — "stand-alone plug & play system that can be installed in any other cell of adequate dimensions"
Read source ↗Shielded syringes out
µ DDS-A dispenses into already-shielded syringes — the output is patient-ready, no further re-shielding step. It also handles open and closed vials. The shape of the output matches what your injection room is set up for.

Read source ↗274 units worldwide
(the manufacturer )publishes 274 µ DDS-A installations around the world — a meaningfully larger reference base than the CRP's 100 units. The device exists, ships, and works in clinical practice across many sites.

Read source ↗Manual backup mode
µ DDS-A has a built-in easy-manual backup mode. The radiopharmacist can complete a dispense by hand from the same module when its automation is being serviced — defense-in-depth, two levels deep, without falling back to improvised gear.

Read source ↗Pairs with the SYNT + FLEX + CRP stack
SYNT is the synthesis cell. FLEX is the Grade A dispensing cell. CRP is the primary automation inside it. µ DDS-A is the backup dispensing module. Specified together as a the manufacturer stack — one calibration chain, one teleassistance contract, one AERB import path through Saxsons.

Scope of this page
µ DDS-A is a dispensing module, not a hot cell. Lead shielding, Grade A environment and AERB licensing all sit with the host cell (typically the FLEX in a Saxsons-supplied Indian setup). The F-18 primary-use focus and the "backup dispenser" positioning are Saxsons-supplied market realities — the µ DDS-A public page uses generic "PET and SPECT radiopharmaceutical" language and doesn\'t designate it as a backup product. Compliance claim on the manufacturer page is generic "in compliance with current GMP"; we do not assert Annex 1 / Annex 3 certification.
