MAIN FEATURES
The Simple Origin Dual Grid Cryo Transfer Holder is a high-performance cryogenic TEM holder designed for extended cryo-EM acquisition with dual-grid capability.
Unlike standard single-grid holders, this system:
Accepts two 3 mm TEM grids
Allows grid selection via dewar-mounted selector
Provides extended acquisition time (up to 10 hours)
Enables high tilt angles due to 1.5 mm thin tip
Offers excellent thermal and mechanical stability
CRYOGENIC PERFORMANCE
According to the technical specification (Offer p.2 and Technical Memo)
Tip temperature: < -180°C
Holding time without refill: 9–10 hours
Drift rate: < 2 nm/min (1.5 nm/min achievable depending on TEM stability)
Resolution: better than 2.4 Å
Axis-symmetric dewar design for enhanced tilt stability
This extended 10-hour autonomy is a major operational advantage compared to standard 3–4 hour cryo holders.
TILT PERFORMANCE
Tip thickness: 1.5 mm
Allows wide tilt range (≥ ±70°, depending on pole piece gap)
Compatible with high-tilt tomography workflows
SPECIMEN CAPACITY
Dual grid configuration (2 × 3 mm TEM grids)
Compatible with:
Standard 3 mm grids (Model 205 & 215)
FEI/Thermo Fisher Autoloader grids (Model 200 & 210)
Ideal for cryo-EM labs seeking workflow optimization and reduced grid exchange frequency.
