Flasks

Three convenient sizes of high quality borosilicate glass flasks are available from Thermo Electron: 300 ml, 500 ml and 1000 ml. These flasks have been specifically designed for freeze drying and feature wide-mouth openings for easy access to the dried material. All three flasks feature the same 75 mm diameter opening. This facilitates the use of a single, universal, flask lid that is interchangeable between different size flasks. In addition, rubber cone connectors are available to facilitate the use of standard laboratory flasks. Adapters are also available for use with Labconco ^® and VirTis^® flask lids.

Acrylic Lid

The Acrylic Lid is a 25 mm thick disc of clear acrylic plastic with two 20 mm openings sealed with special removable rubber plugs. These openings allow for remote sensing of temperature inside the drying accessory while under vacuum.

The lid may be used with both Drum Manifold accessories (see Column and Drum Manifolds) and the Acrylic Cylinder accessory (see Specimen Drying Accessories).

Flask Lid with Adapter

Thermo Electron provides a snap-on universal flask lid that fits all three widemouth flasks. The neoprene rubber lid houses a replaceable filter secured with a rubber O-ring. The filter prevents system and sample contamination when applying vacuum or venting the flask. The lid is also supplied with a metal adapter that connects to the valves on the column and drum manifolds.
