Why Choose an Ear Punch?

Ear punching is a widely used identification method in laboratory animal research because it creates permanent identification marks without requiring tags or additional identification devices. Researchers can use standardized ear punch patterns to uniquely identify each animal while maintaining accurate colony records.

Ear Punch vs. Ear Tags

Ear Punch	Ear Tags
Permanent identification marks	Numbered tag identification
No tag remains on the animal	Visible numbered tag
No replacement tags required	Tags may need replacement if lost
Ideal for standardized notch systems	Ideal for numbered individual identification

FAQs

What is an ear punch used for?

An ear punch is used to create small, permanent identification marks in the ears of laboratory animals, allowing researchers to distinguish individual animals throughout a study.

Which animals can this ear punch be used on?

It is commonly used for: mice, rats, and other small laboratory rodents.

Is ear punching a permanent identification method?

Yes. Ear punches create permanent identification marks that can be used alone or as part of an established ear-notch identification system.

Which length and diameter do I need?

1mm diameter is smaller, less invasive hole; suits very young or small animals, or where a subtler mark is preferred while 2mm diameter is larger, more visible hole for easier identification at a glance. The shorter length (5cm, 5.5cm) is more compact, easier control for close, precise work. The longer length (7cm, 7.6cm) allows greater reach and leverage, which some users prefer for repeated high-volume tagging sessions.
