LD Series Dewars

The LD Series cryogenic dewars are perfect for storing and dispensing small amounts of liquid nitrogen. The LD Series includes a beaker-style dewar with a wide mouth (LD5) and a pitcher-style model (LD4) for easy pouring.

  • State-of-the-art construction and advances insulation materials for high thermal efficiency
  • Ribbed, high-strength aluminum body, magniformed neck tube design, and durable paint make these dewars rugged
  • Easy to operate—light-weight, snap-on cap and precise-fitting neck tube assure tight closure and easy access
  • Large, convenient handles for easy maneuvering
  • Superior vacuum and insulation performance for maximum holding times
