Barnstead/Thermolyne Locator® Cryobiological Storage Systems, Thermo Scientific


Compact cryogenic storage systems feature durable construction and advanced vacuum insulated to minimize liquid nitrogen (LN2) evaporation.

  • Vessels feature a secure locking clasp to prevent unauthorized access
  • Alarm alerts operator in the event of excessive liquid nitrogen loss
  • Systems are suitable for manual and computerized inventory methods

Temperature uniformity assures that samples are stored at –180°C (–292°F) even when the vessel contains less than 5 cm (2") of LN2 and also vacuum insulation reduces the operating costs.

The rugged, steel, 4-wheel storage vessel transporter cart reduces the risk of accidental spillage or tipping of vessels. The racks can accommodate 13.3x13.3cm (51/4 x 51/4") boxes, which are sold separately.

Ordering information: Liquid nitrogen level monitor is sold separately. Boxes not included. Locator systems are supplied with manufacturer's three-year warranty and stainless steel storage racks.
