The E3100 large chamber critical point dryer has been an industry standard for over 35 years and is used in numerous scanning electron microscopy (SEM) laboratories around the world. Primarily used for the critical point drying biological and geological specimens, the E3100 can also used for the controlled drying of MEMs, aerogels and hydrogels.The design of the E3100 features a large, horizontal pressure chamber measuring 63.5 mm internal diameter x 82 mm in length. The chamber has an external water jacket for temperature control and specimens are introduced via a removable rear door. The front of the chamber is fitted with a 25 mm diameter window which gives an unsurpassed view of the liquid level during the critical point drying process.
