hemaPEN® is an easy-to-use microsampling device that collects 4 volumetrically identical capillary samples from a single finger-stick. Click it shut & 4 DBS samples are locked inside until lab processing.

Indications for Use: Enables collection of 4 blood samples by a healthcare professional for shipment to an accredited laboratory for analysis.

volumetric accuracy + sample integrity + convenience = hemaPEN

The hemaPEN® offers a unique approach to capillary sampling with its 4 integrated capillary tubes within the device for easier handling. The glass capillaries simultaneously draw 4 samples from a single finger-stick, transferring 4 blood spots onto a DBS cartridge inside the hemaPEN.

Easy to Use

End-users like the intuitive pen-like design of hemaPEN® and the fact that a single finger-stick is all they need to rapidly collect four microsamples.

The hemaPEN collects a sample from any angle, so it is nearly impossible to under- or over-sample. This benefits end-users with limited mobility. Offer hemaPEN to remote study cohorts for sampling with ease – anywhere, anytime.

The hemaPEN is a one-time use, low-volume sampling device.

Easy to Secure, Store & Transport

The hemaPEN® ensures sample security, making it suitable for anti-doping in sports or other programs where sample tampering is a concern.

After end-users collect the samples, they place the point of the hemaPEN into its plastic base and push down until they hear a "click." That locks the hemaPEN shut and also transfers the 4 capillary samples onto 4 pre-punched DBS papers inside.

Re-seal hemaPEN in its specimen bag & ship to the lab. Internal desiccant keeps the samples dry during storage and transport.

Easy to Analyze

Labs set up for a DBS workflow should find it easy to adopt hemaPEN microsampling methods. 
A benefit of hemaPEN over traditional DBS cards is that the aliquoting & hole-punching steps are eliminated. This is because the 4 DBS samples in the hemaPEN are collected onto 4 pre-punched, industry-standard DBS filter papers within. 
The hemaPEN is suited for both manual & automated DBS processing workflows. Lab tools available include the hemaPEN® Opening Tool, hemaPEN®-QC, hemaPEN® Tube Accessioning Tool & hemaPEN® 96-Rack Adaptor.
