Saxsons PET Tungsten Syringe ShieldTungsten Shielding for F-18 · Ga-68 · Lu-177 · Cu-64 Dispensing

Saxsons own-brand tungsten syringe shield engineered for PET radiopharmaceutical dispensing — F-18, Ga-68, Cu-64 — and Lu-177 theranostic prep. High-density tungsten-alloy shielding reduces finger dose to a fraction of the bare-syringe value; the engraved lead-glass viewing window keeps the dose volume visible while the shielding stays in place. Turn-lock retention on the dispense-line workhorse sizes, thumb-screw on the outlier sizes. Size-coded end caps in Red / Black / Blue make the right shield obvious at glance-speed. Designed and manufactured in India in an ISO 9001 / ISO 13485 approved plant. Sign in to view the complete configuration matrix.

Key Features

Saxsons own-brand product — designed and manufactured in India by Saxsons Healthcare Pvt. Ltd. in an ISO 9001 / ISO 13485 approved plant
Tungsten-alloy shielding — high atomic number and high density deliver high attenuation per millimetre of shielding wall, keeping the chassis smaller and lighter
PET-tier shielding attenuates the annihilation radiation from F-18 and Ga-68 dispensing enough to bring extremity dose per dispense below the AERB / ICRP action threshold
Engraved lead-glass viewing window on the side — operator reads the calibration scale and visually confirms the dose volume without removing the shield
Turn-lock retention on the dispense-line workhorse sizes — one twist secures the syringe; no fiddly thumb-screw on the high-throughput dispense line

Applications

Tungsten PET-tier shielding is the design choice between bare-syringe finger dose and the AERB limit

[¹⁸F]FDG unit-dose dispensing

Per-patient FDG dispensing — turn-lock shield sized to the routine unit-dose syringe. Operator reads the calibrated volume through the lead-glass window; dose is assayed against the dose-calibrator without ever exposing fingers to the bare syringe.

Ga-68 PET tracer dispensing

Turn-lock shield for Ga-68-DOTATATE / DOTATOC / PSMA-11 dispensing post-generator elution. The Red / Black / Blue size-coded caps make the right shield obvious at glance-speed against the bench tray.

Lu-177 theranostic dispensing

Higher-volume variants for Lu-177-DOTATATE and PSMA-617 patient-dose dispensing. Tungsten covers the Lu-177 photopeak and the annihilation contribution from Lu-177m in a compact chassis.

Cu-64 investigational dispensing

Investigator-initiated Cu-64 unit-dose dispensing for micro-dose research protocols. Standard PET tungsten attenuation applies across the Cu-64 emission profile.

Multi-size dispensing line

Size-coded caps let the radiopharmacist pick the right shield at glance-speed — Red, Black and Blue map onto the routine syringe sizes on the bench. Prevents wrong-size pick-up during the high-throughput dispensing shift; tray-level organisation by cap colour matches the daily syringe-size mix.

Hot-lab finger-dosimetry programme

TLD ring-badge programme — extremity-dose log records dose per dispense per operator. Tungsten PET-tier shielding is the design choice that keeps the annual extremity dose below the AERB 500 mSv occupational limit at typical PET workloads.

Why Saxsons PET Tungsten Syringe Shield?

Red · Black · Blue

Size-coded caps

The cap colour tells the operator which size shield they're holding before they read the engraving. On a busy PET dispensing line where 30+ doses pass through per shift, glance-speed size identification prevents the wrong-size shield being picked up and dispensed against.

Tungsten

PET shielding tier

Tungsten's high atomic number and high density mean the shielding wall stays thin while still bringing the primary annihilation flux down to a fraction of the bare-syringe surface. The compact chassis keeps the shield in hand for hours without operator fatigue on the high-throughput PET line.

500 mSv

AERB extremity dose limit

AERB caps the annual extremity (skin / fingers) dose for radiation workers at 500 mSv. A high-volume PET radiopharmacy dispensing 30+ FDG doses per shift can reach a measurable fraction of that limit with bare-syringe handling; a tungsten PET-tier shield brings the per-dispense extremity dose to a level the annual budget comfortably absorbs.

Why tungsten — the physics that gates PET syringe shielding

How tungsten delivers high per-millimetre attenuation at PET energies, the AERB / ICRP extremity-dose framework, why turn-lock matters for high-throughput dispensing lines, and how size-coded caps cut wrong-size pick-up at the bench.

Variant matrix

Pick the size, the shielding tier, the variant

Five syringe sizes, three tungsten shielding tiers and three geometry variants. The per-isotope dispensing-line build sheet matches the size to the dose volume and the variant to the workflow geometry; the size-coded cap (Red = 2 cc, Black = 3 cc, Blue = 5 cc) makes the right shield obvious at glance-speed.
