Day-Impex Dilvac Dewar Flasks

There are two ranges of the Day-Impex Dilvac Dewar flasks in containers. They all utilise the proven borosilicate glass inner vessels and are offered in stove-enamelled steel and hygienic satin finish stainless steel, with capacities of 200cc-10 litres. Designed for safe use and transportation of liquid gases, all Dilvac Dewar flasks are manufactured to exacting standards and represent the highest quality units available today for laboratory use.

The Dewars are designed with practicality and safety in mind. Many of the range of 21 models have features such as vented, clamped lids, carrying handles and rubber-cushioned bases.

Universal Style: With Handle and Lid

Fitted in highest-quality stainless steel containers, therefore rust-free, anti-corrosive, all hygienic and strong. These Dewars have an all stainless steel lid with self-contained insulation. Toggle-clamps secure the lid to the body for safe transportation.

Shallow Form with Wide Mouth

Wide-mouthed shallow glass Dewars, dish-shaped, fitted in stainless steel protective containers. These can be used with magnetic stirrer, designed to accept standard boiling flask up to 2 litres in capacity, for rapid freezing tempering of stirring rods, pestles, etc. The shallow form configuration allows for a minimum amount of coolant to be used.

Blue enamelled Steel: Wide and Narrow Mouth

A range of low-cost utility Dewar flasks specially designed for laboratory, hospital and industrial use. Safe for use with all liquid gases and ideal for cold traps. High-quality borosilicate glass inner flasks, ultra-low evacuated in attractive blue stove-enamelled steel outer container, available in 8 capacities. There are also 4 sizes in this multi-purpose range with models that have an insulated lid, fold-down carrying handle and cushioned base to prevent benchtop damage.

New to the Dilvac range comes the 1 litre, 2 litre and 4½ litre tried and trusted borosilicate glass Dewars housed in a blue steel enamelled container
