G Pen Hyer Vaporizer

Concentrates Ground Material
$249.95

or 4 interest-free payments of $62.49 USD with

The G Pen Hyer®️ is an intuitively designed, dual-use, portable vaporizer that works with concentrates or dried herb and pairs with any glass-on-glass water piece in one’s arsenal.  Manufactured with the highest quality materials, including a quartz heating element, the G Pen Hyer features smart heating technology with constant temperature output to deliver best-in-class flavor and vapor production.

Featuring a 6,000mAh rechargeable lithium-ion battery with rapid, pass-through charging via USB-C, in a lightweight and durable, anodized aluminum casing, the G Pen Hyer redefines the limits of sheer power and portability.  Utilizing a simple three-button operation and five-LED user interface, the G Pen Hyer allows for easy set-up and activation while delivering an uncompromising experience.

A premium braided power cable with durable snap-in magnetic attachments connects the battery to a lightweight, anodized aluminum tank housing, in which the G Pen Hyer Quartz Tank for Concentrates or Dry Herb Tank* can be easily threaded in and out.  The Concentrates Tank is heated by a custom-stamped stainless steel heating element and features a full Quartz chamber and internal up-stem that provides maximum surface area for heating, efficient airflow, and an optimal vaporization of concentrate materials.  

The final component in the superior performance of the G Pen Hyer Quartz Tank for Concentrates is the Concentrates Tank Cap, magnetically attached and made of anodized aluminum with a built-in ceramic liner and dual airflow holes for smooth, rotary functionality.  The included stainless steel wax tool can also be attached to the top or side of the tank cap for easy placement and accessibility.

Each G Pen Hyer Vaporizer kit comes with a 14mm male glass adapter (10mm and 18mm glass adapters sold separately).  All kit components come neatly packed in an included hemp travel case with a mesh pocket for additional accessories.

or 4 interest-free payments of $62.49 USD with

Grenco Science is proud to introduce a profound advancement in portable, ground material vaporization with the highly anticipated release of the G Pen Elite II.  Standing on the shoulders of its predecessor, and in celebration of the 10-year anniversary of Grenco Science, the G Pen Elite II rises above and beyond, redefining the standards of herbal vaporization through its innovative dual-heater and air-path system which allows it to access the full array of flavors and effects that flower has to offer.

Engineered with a patented clean air intake and patent-pending convection and conduction dual heater technology, the Elite II delivers pure and expansive vaporization with every dose through a full ceramic heating chamber and individual temperature control between 200º - 430ºF (93º - 221ºC).  Designed to cater to individual preference, the Elite II comes equipped with a full-color, high resolution TFT display along with the introduction of a curated settings menu allowing a customizable interface, including session duration, heating method, haptic feedback and more.  

With a perfect marriage of form and function, sleek look, and ergonomic design, the Elite II is built to ensure each pull is a memorable experience.  The clean air intake doubles as a built-in carb molded directly into the durable zinc-alloy body, ergonomically positioned at the hand’s thumb-grip to control the amount of airflow desired.  The Elite II Mouthpiece is made of zirconia with an integrated spiral air-path, delivering cooled vapor and a comfortable contact temperature to the lips, and is magnetically attached for easy removal.  At the opposite end, a handy built-in pick tool at the bottom of the device can be used to assist in both packing and clearing the oven.

Powered by a 2100mAh rechargeable lithium-ion battery with USB-C fast-charging, the Elite II can be fully charged in 1.5 hours and run for an hour of vaporization time.  This complete kit standardly includes a protective silicone sleeve that encases the entirety of the unit, packed neatly within a sleek and sturdy hemp travel case.
