Magnetic holders are convenient for holding KBr pellets or thin polymer films. They are also useful for mounting a 13mm crystal that has been used as a microscope slide in a standard spectrophotometer sample compartment. The film sample, pellet or optic is held in place by a magnetized rubber plate. These holders fit the universal 2" x 3" slide mount in all spectrophotometers. Use of paper inserts facilitates mounting small samples.

You must specify the holder with which you will use the magnet. (Please select the Request Information Button)

N/A Smaller samples may be mounted on a slotted opaque card (masking the spectrophotometer beam) and then inserted into the Magnetic Film Holder. The film sample, pellet or optic is held in place by a magnetized rubber plate. These holders fit in the universal 2” x 3” slide mount in all spectrophotometers. Use of paper inserts facilitates mounting small samples and pressing KBr pellets.

Paper inserts are used to make KBr pellets by dropping them into the bore of a 13mm die set. The OD of the insert is slightly less than 13mm. Several hole sizes are available to enable formation of pellets from limited sample quantities. These inserts frame the pellet for ease of handling and also provide a visual reference for the proper amount of KBr powder which improves pellet quality and consistency.
