Silson standard silicon nitride membranes are available in both Si3N4 and SiRN with thickness ranging from 10 to 1000 nm, depending on the type of silicon nitride. Standard frame sizes vary from those compatible with TEM grid holders to 23.5 mm with a wide range of membrane sizes depending on the frame size.

Silicon nitride membranes are sized at 0.05, 0.1, 0.25, 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0 mm increasing in 1.0 mm increments to 19.0 mm, although not all membrane sizes are available for each membrane thickness.

The largest standard membrane available in a 5.0 mm frame is 2.0 mm x 2.0 mm, in a 7.5 mm frame is 3.0 mm x 3.0 mm and for a 10.0 mm frame it is 6.0 mm x 6.0 mm. Membranes up to 19.0 mm x 19.0 mm have been produced in 23.5 mm x 23.5 mm frames.

The chart below illustrates standard silicon nitride membrane availability as a function of frame and membrane size and thickness.

Although the most popular membranes are square, rectangular membranes are also available and are particularly beneficial when approaching the limit for a given membrane size and thickness combination.

It is possible to increase overall window size as a function of film thickness by producing arrays of membranes to produce multi-element window which are described separately. These are also useful for compartmentalisation of samples for experiments.

Please take a look at our pricing table below, but please note that Minimum Order Quantity (MOQ) requirements do not always apply if we have membranes available from pre-manufactured stock, or especially if there is flexibility on product size or thickness, so it is always worth contacting sales@silson-8j81h7lw7l.live-website.com to make an enquiry or to discuss a smaller quantity requirement!
