Polaris Series - Cryogenic Inventory Racking System
The stainless-steel Polaris inventory racking systems are designed for long-term sample storage applications.
Unlike traditional cryogenic storage that immerses samples in liquid nitrogen, or vapour storage systems where samples are housed above a liquid reservoir, Polaris is a truly dry storage system. A nitrogen jacket surrounds the sides and base of a central chamber creating a dry storage system and ensures temperature uniformity.
Available in five storage sizes, the largest can store up to 107,100 vials.
Product Description
- Dry working chamber – virtually no risk of cross-contamination or exploding vials
- Lower sample storage temperature than conventional units
- Full volume of chamber can be utilised for racking. No loss of storage space under the lower plate as seen in vapour phase vessels
- Full logging of temperature/alarms
- Built-in high-level safety and sample protection
Principles of Dry Storage
- More uniform temperature profile from base to lid.
- Liquid envelops the chamber including sides
- Physical separation of samples from LN2
- Lid can be left open for access for several hours
- Dry storage offers -190 °C with all vessels
Polaris Sensors
- Temperature Sensor – PT1000 Class A (measuring range -200 °C to +200 °C) (calibration point -196 °C)
- Level Sensors (Cryogenics Proprietary Sensors responsive to LN2 vs gaseous phase) – Low Alarm/ High Alarm
- Continuous Level Capacitance Probe (CryoGauge 242 – battery powered – 2 yrs. – standard AA cell. Accuracy +/- 5mm. Pressure test 40 bar
- Gas Vent Sensor (QLA100GV probe – capacitance probe. Pressure tested to 10 bar)
- Available port for 3rd party temp sensor (8mm ID)
