1.0 Introduction
The Harris e-Core is a compact, versatile, electric coring device designed for unrestricted sampling
of a wide range of DNA storage products or other sample substrates. The Harris e-Core was created
to bridge the gap between the lower cost, manual Harris Micro-Punch and Harris Uni-Core and the
automated bench top punching platforms. The ergonomic “joy stick” grip and the e-Core’s simple
operation provide comfort and efficiency, integrating smoothly into all levels of laboratory sample
throughput. The user has complete management of the disc recovery process, the coring speed and
disc delivery.
The Harris e-Core, like the Harris Micro-Punch and Harris Uni-Core, continues to offer the same
unique combination of patented simultaneous sampling features: coring, retrieving and storing in
a single operation, but with dramatically increased processing times. The Harris e-Core ejection
system, like its predecessors, still offers the user the ability to control both the speed and delivery
of the ejected disc. Most importantly the Harris e-Core ejection system does not generate static,
affecting both accuracy and precision. The manually controlled ejection system and lack of static
generated ensures accurate disc delivery.
The Harris e-Core is a coring tool and not a punch. The Harris e-Core has been designed to utilize
dedicated replaceable Harris Micro-Punch Tips. The razor sharp cutting edge on the Harris Micro-
Punch Tip cleanly and precisely cores discs from substrates, all but eliminating the creation of
artefacts and potential cross contamination between sampling.
The Harris e-Core is currently available in three models identified by their respective industry standard
coring diameters: 1.2 mm, 2.0 mm and 3.0 mm. Each model has a fixed diameter plunger ejection
rod ensuring efficient sample ejection. The Harris e-Core utilizes Harris Micro-Punch Tips which
conveniently thread to the Harris e-Core drive shaft. Each tip is made from 304 stainless steel with a
nitride coating and Rockwell Hardness of Rc60. The ejection rod is made from 304 stainless steel.
