The Attachment for Hard-to-Grip Samples is an ideal tool for tension testing of short or fragile samples that present difficulties when clamped with a chuck. The device measures tension strength by pulling apart left and right plates, which secure the sample’s ends using adhesive. Furthermore, the attachment is suitable for assessing tension strength in thin, rod-shaped samples, utilizing the plates’ central groove. This specially designed attachment provides a precise and effective solution for evaluating tension strength in samples that are typically challenging to grip using conventional methods.
