H-Pette^® Dispenser
Until now, there was really no alternative to differential slide preparation but two glass slides, a drop of blood from a capillary tube or pipette and a technician's skilled hands.

Helena's new H-Pette offers a new approach to slide preparation that eliminates the hazards of open tubes of blood and cuts consumption of slides and transfer pipettes. In addition to saving dollars on disposables, increased efficiency and safety are key benefits.

Just insert the H-Pette into the stopper of any size blood collection tube, invert tube and transfer the drop of blood to a glass slide. Rotate the tube and use the attached paddle to make your smears just as you would with a slide. The H-Pette remains in place in the stopper and is disposed with the tube as a biohazard. It can also be easily removed if necessary. H-Pettes are also available without blades and are ideal for transferring sample to test cassettes and slides.

H-Pette is available through Helena Laboratories,

Step 1. Place H-Pette’s cannula in the center of the stopper of the collection tube. Gently press until the cannula completely penetrates the septum. The tube is now ready for use.

Caution: Cannula is sharp; care should be taken in handling.

Step 2. Invert tube at an angle as shown (blade side up, if bladed). Gently press the round edge of the H-Pette to the glass slide to transfer sample to the slide.

Step 3 for H-Pettes with Blade. Rotate tube to turn paddle side down. Grasp the circular disc as shown and use the paddle to make a smear just as you would a glass slide. A 15-25° angle of incidence gives optimum results. H-Pette can be removed or disposed with the collection tube.
