Grindervac: Grinder and Vacuum-Sealed Herb Container in One
The Grindervac is a pocket-sized herb grinder with a built-in vacuum-sealed storage compartment that keeps your ground herbs fresh and odour-free. Made by TightPac from military-grade BPA-free plastic, it grinds herbs, spices, and nuts, then drops everything straight into an airtight chamber below. No separate containers, no stale leftovers, no fuss — just twist, grind, seal, and go. You can buy the Grindervac at Azarius and get it shipped to your door.
What Makes the Grindervac Worth Picking Up
The Grindervac combines grinding and vacuum-sealed storage in a single lightweight device, eliminating the need for separate containers. Most grinders do one job: they grind. Then you're left tapping herb out onto a rolling tray, scooping it into a baggie, and watching half of it stick to the teeth. The Grindervac skips all that. You push the cap down, twist until you've got the consistency you want, and the ground material falls directly into the vacuum-sealed container underneath. Twist the base shut and it's locked airtight — no smell leaking out, no moisture getting in.
We've handled a lot of grinders over the years, and the thing that surprised us about this one is the weight. It's genuinely light — feels like it could snap, but it doesn't. That military-grade plastic is deceptively tough. You can toss it in a rucksack, a coat pocket, or a festival bag without worrying about it cracking. It's not going to replace a heavy aluminium four-piece grinder on your desk at home, but that's not what it's for. This is the grinder you take with you.
One honest limitation: the plastic teeth won't give you the ultra-fine grind you'd get from a metal grinder with a kief screen. If you want powder-fine consistency, look at a metal four-piece like the SLX Grinder. But for a quick, even grind that stays fresh in your pocket? The Grindervac is the best portable grinder-and-storage combo we've come across.

Grindervac vs Other Portable Grinders
The Grindervac outperforms most portable grinders on storage convenience, though it trades grind fineness for that advantage. Here's how it stacks up against common alternatives:
| Feature | Grindervac | Standard Plastic Grinder | Metal Four-Piece Grinder |
|---|---|---|---|
| Built-in vacuum storage | Yes | No | No |
| Odour-proof | Yes | No | No |
| Kief catcher | No | No | Yes |
| Grind fineness | Medium | Coarse | Fine to very fine |
| Weight | Very light | Very light | Heavy |
| Portability | Excellent | Good | Moderate |
| Material | Military-grade BPA-free plastic | Standard plastic | Aluminium or zinc alloy |
| Herb freshness after 24 h | Excellent | Poor | Poor |
If grind precision and kief collection matter most, a metal grinder like the SLX Grinder is the better desktop choice. If you want to grind and carry without a second container, order the Grindervac — nothing else in this category matches its seal.
How to Use the Grindervac
The Grindervac works with a simple push-and-twist mechanism that requires no threading or alignment. It's intuitive from the first use.
- Remove the cap from the Grindervac body. You'll see the grinder teeth inside the cap and a matching set on the top of the container.
- Place your herbs, spices, or other dry material into the grinder area on top of the container. Don't overfill — about a gram or two at a time works best for an even grind.
- Push the cap down onto the body and twist. Keep twisting until you've reached the consistency you want. Coarser material needs fewer turns; finer material needs more.
- Once ground, the material drops through the holes into the airtight vacuum chamber below. Give it a gentle tap if anything's clinging to the teeth.
- Use the included TightPac poker to scrape out any stubborn bits stuck between the grinder teeth. This little tool gets into the gaps that your fingers can't reach.
- Twist the base firmly shut. The threaded twist-lock creates the vacuum seal — you'll feel a slight resistance when it's properly closed. That's your herbs locked in fresh.
- To access your stored herbs later, simply twist the base open. The vacuum releases and your ground material is right there, ready to go.
Why You Actually Need a Grinder with Built-In Storage
A combined grinder-and-storage unit eliminates the most common cause of stale herbs: transferring ground material between separate containers. Here's a scenario we see constantly: someone grinds their herbs at home, tips them into a plastic bag or a film canister, and by the time they get where they're going, the herbs have dried out, lost their flavour, and half the good stuff is stuck to the inside of whatever container they used. Separate grinder, separate container, separate headache.
The Grindervac collapses that whole process into one object. Grind and store in the same device, sealed airtight within seconds. The vacuum seal isn't just marketing fluff — TightPac built their name on vacuum storage containers, and the same technology sits inside this grinder. Moisture stays out, freshness stays in, and odour doesn't escape. That last point matters more than you'd think if you're carrying herbs in a bag or a car. According to EMCDDA research on botanical preservation, airtight storage significantly slows the degradation of volatile aromatic compounds in dried plant material — which is exactly what the Grindervac's vacuum chamber is designed to do.
It's also genuinely useful in the kitchen. Heading outdoors where you want fresh-ground garlic or rosemary? Barbecue where you don't want to haul a spice rack? The 10-gram capacity is enough for a solid session's worth of whatever you're grinding, and the pocket-friendly size means it actually comes with you instead of sitting in a drawer.
Complete your setup: pair the Grindervac with a TightVac storage container for bulk herb storage at home — grind what you need into the Grindervac, keep the rest vacuum-sealed in the larger container. If you're after a heavier desktop grinder for home use, the SLX Grinder offers a ceramic-coated aluminium build with a kief catcher. For rolling on the go, grab a pack of RAW Rolling Papers to round out your portable kit.
From Our Counter
We've been stocking grinders since the early 2000s, and the number one complaint we hear is always the same: "my herbs go stale before I finish them." The Grindervac is the simplest fix we've found for that. It's not the most powerful grinder on the shelf — it won't chew through large, dense buds the way a heavy metal grinder will — but it does something no metal grinder does: keeps your ground material vacuum-sealed the moment it's done.
The poker tool is a nice touch, too. Plastic grinder teeth tend to hold onto fine particles more than metal ones, and without the poker you'd be blowing into the thing like a kazoo trying to get the last bits out. TightPac clearly thought about that, and it shows. Small detail, big difference in daily use.
One more thing we've noticed after years of selling these: customers who buy the Grindervac almost never come back complaining about freshness. We can't say the same for people using standard plastic grinders with zip-lock bags. If you're tired of dry, flavourless herbs, get yourself a Grindervac and stop overthinking portable storage. It just works.
Frequently Asked Questions
Is the Grindervac really airtight and odour-proof?
Yes. TightPac's twist-lock seal creates a genuine vacuum that blocks both air exchange and odour. We've left herbs in one for over a week with no detectable smell on the outside. It's the same vacuum technology used in their standalone TightVac containers.
Can I grind things other than dry herbs in the Grindervac?
Absolutely. The Grindervac handles garlic, cloves, nuts, dried spices, and most other dry or semi-dry materials. It's a solid kitchen companion for camping and barbecues. Just avoid anything wet or oily — the plastic teeth aren't designed for that and it'll gum up.
How does the Grindervac compare to a metal herb grinder?
A metal four-piece grinder with a kief screen gives you a finer, more consistent grind and catches trichomes separately. The Grindervac trades that precision for portability and built-in vacuum storage. If you grind at home, go metal. If you grind on the move, the Grindervac wins.
How much herb can the Grindervac hold?
The vacuum chamber holds approximately 10 grams of dry herb, which is about 0.07 litres of volume. That's enough for several sessions depending on how much you use at a time.
Is the Grindervac durable enough for travel?
It's made from military-grade BPA-free plastic, which is genuinely tough. We've seen these survive being dropped on concrete and kicked around festival campsites. The plastic flexes rather than cracking, which is actually an advantage over brittle aluminium grinders at this price point.
How do I clean the Grindervac?
Disassemble the cap from the body and use the included TightPac poker to scrape residue from the teeth. For a deeper clean, soak both pieces in warm water with a drop of washing-up liquid, then dry thoroughly before reassembling. Avoid boiling water — the plastic can warp at high temperatures.
What's the TightPac poker tool included with the Grindervac?
It's a small pointed tool designed to fit between the grinder teeth and scrape out ground material that gets stuck. Sounds minor, but it makes emptying the Grindervac completely much easier — especially with fine, sticky herbs.
