Product Description
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. 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.

Flexible Sample CompatibilityOur holders support a wide range of sample types, including films, pellets, and papers. Each is designed to ensure optimal presentation and alignment within FTIR, IR, and similar spectrometers for precise, repeatable measurements. Paper inserts can be tailored to specific dimensions, enhancing adaptability for various analytical needs.
Robust Construction & Surface TreatmentMagnetic film holders and KBr pellet holders are crafted from durable materials, featuring passivated or anodized surfaces to resist corrosion. This ensures longevity and consistent performance even when exposed to cleaning agents like alcohol or deionized water, making them ideal for heavy and frequent laboratory use.
User-Friendly OperationDesigned for manual use, these sample holders do not require a power source or complex automation. The clamping mechanisms and magnetic plates facilitate easy sample mounting and removal, streamlining workflow and reducing handling-related errors in your analytical processes.
FAQs of Magnetic Film Holders, KBr Pellet Holder & Paper Inserts:
Q: How do I mount samples using Magnetic Film Holders, KBr Pellet Holders, and Paper Inserts?
A: Samples can be easily positioned within the holder using the magnetic plates or clamping mechanism. Films, pellets, and paper can be placed as specified, with paper inserts adjustable in size for a secure fit. Ensure the sample aligns precisely for accurate spectrometer readings.
Q: What cleaning process should I follow for these sample holders?
A: To clean the holders, rinse them gently with alcohol or deionized water. Their passivated or anodized surfaces protect against corrosion, allowing for regular cleaning without damaging the holders.
Q: When should I choose a magnetic holder versus a KBr pellet holder or paper insert?
A: Select the magnetic film holder for mounting thin films, the KBr pellet holder for crystalline pellets such as KBr discs, and paper inserts for paper samples or customized sample dimensions. The choice depends on your sample type and experimental requirements.
Q: What benefits do these holders offer for spectroscopic analysis?
A: These holders provide reusable, accurate, and secure sample mounting. They ensure precise alignment (within 0.01 mm, instrument-dependent), reduce sample handling time, and accommodate various sample forms for versatile analytical work.
Q: Where are these sample holders compatible for use?
A: They are suitable for use in laboratories, research settings, industrial environments, and educational institutions equipped with FTIR, IR, and other spectrometers. Their compatibility spans most major spectrometer models.
Q: What is the temperature tolerance of these holders during analysis?
A: All holders are designed to operate safely at temperatures up to 200C, which allows for analysis of samples needing moderate heating during spectroscopic measurements.
