The LD Series of cryogenic dewars are designed for storing and dispensing small amounts of liquid nitrogen.The series includes a beaker style dewar with a wide mouth (LD5) and pitcher-style model for easypouring (LD4).
The Worthington Industries Liquid Dewar (LD) Series of cryogenic dewars are designed for storing and dispensing smaller amounts of liquid nitrogen. The line includes a pitcher-style model for easy pouring (LD4), a beaker-style wide-mouth dewar (5LD), and a unique onion-style dewar (CLASSIC-25) that offers an improved center of gravity for ease of lifting and pouring.
Liquid capacities range from 4 liters to 50 liters, and optional accessories include tipping stands and roller bases for certain models, measuring rods for determining liquid level inside the dewars, and an industry-leading liquid withdrawal device that provides safe and secure dispensing of liquid nitrogen at flow rates up to 8 liters per minute.
Watch the video below to learn how to safely and effectively install, fill, and operate the Liquid Withdrawal Device from Worthington Industries. Our Liquid Withdrawal Device is used for pressure transfers of liquid nitrogen from LD25, LD35, and LD50 Dewars. When filling a Dewar, pressure is transferred through the withdrawal device enabling convenient replenishment without removing the device.
Product formerly branded CryoScience by Taylor-Wharton, which was acquired by Worthington Industries.
