7ml Glass Jars- Low Profile heavy bottom- Screw Top with Lids

The 7ml Glass Jar – Low Profile Heavy Bottom with Screw Top Lids is a lab-ready glass container built for extractors, processors, and brands who care about both presentation and precision. The 7ml (0.24 fl oz) capacity is dialed in for concentrate grams, R&D samples, and small-batch fills, while the thick, heavy base keeps your jars planted on busy benches and display shelves. Clear and frosted options let you choose between full product visibility or a softer, premium look without sacrificing stability or seal quality.

Each jar comes paired with a black, non-child-resistant screw top lid that threads smoothly and seals tight, helping protect freshness, aroma, and texture between fills and during transport. The low-profile form factor makes these jars easy to tray, label, store, and ship, whether you’re running a small craft lab or a full production line.

Why it works

• Dialed-in size for concentrates — 7ml (0.24 fl oz) capacity works perfectly for typical concentrate fills, R&D runs, or promo samples without wasting headspace or glass.
• Heavy-bottom stability — The thick, weighted base helps prevent tipping when you’re filling on a crowded table or when these live in a retail display.
• Tight screw-top seal — Black lids thread on clean and snug so your terps, consistency, and potency stay protected between sessions.
• Brand-ready looks — Choose between Clear glass to showcase color and clarity, or Frosted glass for a softer, higher-end aesthetic that still feels lab-grade.
• Low-profile footprint — Short, wide design packs smoothly into trays and boxes, making storage, transport, and inventory checks more efficient.
• Consistent, repeatable packaging — Uniform sizing and threading make it easier to integrate into existing filling, weighing, and labeling workflows.

Best for

These 7ml heavy-bottom jars are made for licensed extractors, small-batch hash makers, and brands who want their concentrates to look as good on the shelf as they do on the lab bench. They drop straight into most existing storage and packaging setups, whether you’re hand-filling or running semi-automated equipment.

They’re also a solid choice for R&D teams needing consistent sample containers, or for anyone who wants a reliable, reusable glass option instead of flimsy single-use plastics.

How to use it

Use these like any precision glass jar in the lab: tare your scale with an empty jar and lid, fill to your target weight or volume, then thread the lid on firmly until you feel the seal engage. The heavy base helps keep things steady while you work, which you’ll really appreciate when you’re moving quickly through a run.

For a cleaner workflow, stage jars on a nonstick dab pad or mat so any stray drips land somewhere easy to wipe up instead of all over your stainless or benchtop.

Once filled and sealed, these jars are ready for labeling, boxing, or cold storage depending on how you handle your finished product. Let the jar and lid come back to room temp before opening to avoid moisture issues, especially if you’re moving between cold storage and warm environments.

Specifications

Fit & workflow considerations

The low-profile heavy-bottom design plays especially well with pre-cut labels and tamper bands sized for short jars, and it’s easy to line up in rows on trays or in shallow boxes. If you’re pairing these with other packaging, they drop nicely into a lot of standard-sized outer cartons and retail boxes used in glass jars and extract packaging.

Because the lids are non-CR, these jars are best suited for lab environments, R&D samples, or markets and applications where child-resistant closures are not required. Always confirm local packaging regulations before using them as your main retail option.

Cleaning & re-use

For re-use, let the jar reach room temperature, then empty any remaining product. A quick soak or rinse with isopropyl alcohol, followed by a fresh water rinse and full dry, will keep your glass looking clean and lab-ready without much effort.

If you’re handling especially sticky runs or want to line jars for easier cleanouts or product removal, consider pairing these with nonstick liners or compatible PTFE and non-stick papers sized to your workflow.

FAQ

• Are these jars truly 7ml? How much concentrate can I realistically fit?
  Yes, the internal volume is approximately 7ml (0.24 fl oz). In practice, most labs use them for typical “gram jar” fills or similar small concentrate fills, leaving a little headspace so product isn’t pressed against the lid.
• Are the lids child-resistant?
  No, these are non-child-resistant (non-CR) screw-top lids. They’re meant for lab use, R&D samples, or markets where CR packaging isn’t required. If you need CR solutions, you can pair these jars with secondary compliant packaging like boxes or bags from our broader mylar bag collection where allowed.
• Can I use these jars for solventless, hydrocarbon, and rosin products?
  These glass jars work well for a wide range of concentrate types, including solventless, rosin, and hydrocarbon extracts, as long as you’re following your own internal handling and storage protocols. For pressing or drying steps before jarring, many labs stage their product on parchment paper or other liners first.
• Do the clear and frosted versions behave differently?
  Functionally, no — they share the same capacity, footprint, and heavy-bottom stability. Clear glass is best when you want full product visibility and color to pop, while frosted glass is great for a softer, premium look or when you’d rather the label and branding be the main focus.
• How should I clean these between uses?
  Let the jar cool to room temperature, then wipe or scrape out any remaining material. For deeper cleaning, soak or rinse in isopropyl alcohol, then rinse with clean water and allow to fully dry before refilling. Lids can be gently wiped and left to dry as well.
• Will these work with my existing labeling and filling setup?
  Most setups that already handle small concentrate jars will work just fine with these, thanks to their consistent dimensions and low profile. If you’re already kitting out a lab with rosin presses, tools, and other gear, they slot in nicely alongside other rosin extraction equipment and workflows.
• Can I use these jars for personal stash instead of just lab work?
  Absolutely. Plenty of people keep a few at home for organizing personal concentrates or samples. If you’re building out a home setup, these pair well with rigs, dabbers, and other essentials from our broader smoke shop products lineup.
