Brief Overview

The microG by Grenco Science may be micro in size, but delivers large clouds of vapor at the push of a button. Designed to vaporize solid concentrates quickly and efficiently, the microG easily fits in your pocket for on-the-go use. Simple loading and simple operation makes the microG one of the most user-friendly portable vaporizers available.

See User Guides below for full usage information.

Get to know the microG Vaporizer

Using Your microG

A: As with most pen vaporizers, the microG is super easy to use. Refer to the full instructions located on the ‘User Guide’ tab, but here is a quick rundown on using the microG:

Charge the microG – This could take a few hours the first time, but subsequent charges should not take longer than 46-60 minutes.

Load the microG – This is easily done by removing the mouthpiece, and using the included key chain tool to apply your concentrates on top of the atomizer coil. Do not load too much, more than a sessions worth is definitely too much. Ensure the concentrate the making contact with the atomizer. Replace mouthpiece and apply silicone mouthpiece covers, if desired.

Power up and Draw – If the switch on the microG is locked, unlock by pressing the button five times. This enables the power switch and the microG is ready to use. Press the button and immediately begin drawing from the microG. Best practice is to keep the microG as vertical as possible during use. Draw until you have had your fill, or the ten-second shut off turns the atomizer off.

Many owners find that taking one more draw through a cooling microG (no power applied while drawing) keeps the air vents from clogging.

A: The microG heats up instantly. With a powerful (for its size) 650mAh battery, the microG heats up fast, and keeps heating long past other vaporizers of this size.
A: There are no temperature settings on the microG. It goes from room temperature to its peak temperature in one second.
A: First and foremost it’s vital that you use the cleanest and purest liquids and concentrates you can find. The microG was designed for use with liquids and concentrates that melt cleanly and leave no particulate behind.

When particulate makes contact with the atomizer, it can overheat and will degrade the lifespan of your cartridge exponentially.

Since the microG has only one temperature setting, its pretty foolproof. Press the button, and draw until you have your fill or until the microG shuts off automatically after 10 seconds.

Adjusting your draw rate can have an effect on vapor thickness; draw faster for thinner vapors, slower for thicker vapors.

A: The microG was designed solely for liquids and concentrates. Do not put aromatic blends into atomizer included with the the microG. There are atomizers available for blends, please contact Grenco Science more information.
A: The charger is rated from 100v to 240v, but you might need an adapter for your outlet if outside North America.

Since the microG has only one temperature setting, it’s essentially foolproof. Press the button, and draw until you have your fill or until the microG shuts off automatically after 10 seconds.

A: The atomizer coil is nickel/aluminum-alloy, the wick is fiberglass, the crucible that surrounds the coil is ceramic, the body is made of steel and plastic. The mouthpieces are silicone.
A: The microG has a nickel/aluminum-alloy atomizer coil that surrounds a fiberglass wick.
A: Liquids and concentrates love high temperatures, so you should not have an overheating issue!
A: It’s best to not fill the heating chamber full. Just apply enough for one session at a time. The microG was not designed to hold more than one session at a time.
A: Occasionally through use, especially when drawing rapidly, the melted concentrate can ride on the sides of the crucible, preventing it from making contact with the atomizer coil. Using the unique included tool, you can ‘push’ the buildup on the sidewalls back down into the crucible for use. Use caution not to make contact with the atomizer, you could damage it very easily.
A: Yes, after ten seconds of use, the microG will power off.

There is also a safety on the power switch, clicking it five times turns off the power button, and repeating this turns the button back on. This is great if you have the microG in your purse, or pocket, as it prevents it from going off accidentally and wasting your battery or worse.

As a general safety rule, do not leave the microG unattended while powered on.

A: The microG Pen atomizers are not rebuildable, you can replace them very easily by disconnecting them from the battery, and replace with a fresh atomizer coil.

On average, atomizer coils last 4-5 weeks of normal use; your experience will vary.

A: There are no screens in the microG.
A: The battery is Elips – C
A: The microG comes with an AC adapter/USB plug, rated from 100v to 240v. The USB plug can be used by itself in a powered USB port anywhere in the world, but if you are charging your microG outside of North America with the included AC adapter an outlet/plug adapter might be needed.
A: When the microG battery is in need of a charge, the power button will flash 8 times when pressed.

At this time, connect the microG battery to the microG Wired USB Charger (at the base of the microG Battery). The microG Wired USB Charger can be connected to either the G Wall Adapter or any compatible USB port. A red LED light will illuminate at the base of the battery to indicate that a charge is being administered.

Once the red LED light turns green, the microG battery has been fully charged.

Cleaning & Maintenance

A: Any concentrate that may have collected on the body of your microG can be removed with a warm damp cloth.

If you need to remove concentrates from inside the crucible, you can do so using your microG Tool. USE CAUTION and be extremely careful not to damage the atomizer coil.

Within the crucible of your microG tank, the coil works to clean itself by clearing off any residue that comes in contact with it. We don’t recommend using any type of liquid cleaning agent in the microG tank, as doing so could cause it to malfunction.

A: On certain parts alcohol is fine. The top cap will incur the most buildup, soaking it in alcohol or cleaning with alcohol soaked cotton swab are effective cleaning methods.

Cleaning the atomizer is not recommended, replace as needed.

Make sure you don’t expose the atomizer or battery to any liquids whatsoever. If you need to clean the outside of the microG, use a warm damp cloth. If the microG gets wet in any way, allow to dry in the sun or a warm dry area until COMPLETELY DRY. Attempting to use the microG if wet will cause serious damage to the unit.

A: The coil atomizer should be replaced as needed on the microG. Over time even the purest concentrates will allow buildup to collect on the Atomizer coil; removing this with a tool will damage the coil.

On average, atomizer coils last 4-5 weeks of normal use; your experience will vary.

Getting the Most Out of Your microG

  • Drawing after the heater has cooled down will allow the air vents to stay free of blockage.
  • Never leave a microG in a hot car. Ever.
  • While using the microG, try and keep it as vertical as possible to avoid potential leakage.
  • Allowing the microG to freeze can damage the atomizer. Avoid temperatures below 40 degrees.
  • The microG ships with two units. Load them both before you head out and be ready to vape when you’re on the go.
  • Use caution with the included G tool, as it could damage the atomizer coil if you aren’t careful.
  • Overloading more than one session’s worth of concentrate is a potential recipe for mess.

microG Maintenance

Cleaning the microG couldn’t be easier. If the atomizer coil has gotten too much buildup, replace it with a new one.

The inside of the mouthpiece will take on the most buildup, soak it in isopropyl alcohol and clean with a cottonswab.

If any concentrate has made it onto the body of the microG, wipe off with a warm damp cloth.

Need Assistance with your microG?

Try these Solutions to common issues:

A: A few things could be causing this. Is the 5-click safety lock in place? Try clicking your microG button five times and see if anything happens.

Are you getting any light at all from the button? If not, make sure that its charged properly. This seems obvious, until you realize the power strip you were plugged into wasn’t turned on. Or…the USB port you were plugged into wasn’t actually a powered USB port. Or…there are many reasons to think your vaporizer is charging…when it isn’t. It happens all the time.

If you have charged it fully, and unlocked the power button, and are still getting no vapors, remove the mouthpiece, press the button, and see if the atomizer is at least getting warm?

If you have no activity from a fully charged microG, it’s possible that your atomizer has died. Try that atomizer on the other microG that came in the package, and see if it works. If not, we have replacement cartridges available.

A: Make sure your microG is fully charged, and the atomizer coil is fully seated and loaded properly (not overloaded).
A: The microG was designed for liquids and concentrates only, so loading aromatic blends will result in undesired results. Do not load aromatic blends in coils designed for liquids. Grenco Science makes coils for blends, please contact them for more information.
A: This is a natural situation with the microG. There are two fresh air intake holes on the sides of the microG atomizer cartridge. They are connected to small holes in the bottom of the crucible. When your solid concentrate melts, it may fill the holes located in the bottom of the crucible. When this liquid cools, it blocks the holes, so drawing is difficult.

This is easily remedied by heating up the microG for a short time, blocking one of the two holes on the side of the cartridge (they are in the silver band) and drawing. If warm enough, this should clear on one side, then repeat on the other side.

As you continue to use the microG, be mindful of this blockage potential. One trick to prevent it from happening is to continue to draw through through the microG once a minute as it is cooling. Once all the internals have cooled to room temperature, you can stop.

If these troubleshooting tips don’t work, please contact us.
