Square Black Glass Jar 5 ml. designed for BHO Extraction and concentrate storage. Discreet black design, stackable square shape and airtight seal that protects aromas and terpenes.
Ideal to include in BHO Accessories and BHO extraction kits. Hydroponics Blanes with discreet shipping throughout our Grow Shop.

This 5 ml Black Square Glass Jar is designed to safeguard delicate extracts derived from BHO tools such as purge systems, ovens, vacuum pumps, and heating plates.
The black finish acts as a barrier against light, helping preserve the terpene profile and cannabinoid potency. The square geometry makes it easier to keep trays and cases organized, preventing rolling and improving space efficiency.
The tough glass tolerates moderate thermal changes typical of the post-process (curing, whipping, resting), while the screw cap with gasket preserves freshness and prevents contamination from dust or moisture.
Calibrated 5 ml capacity for personal portions or lab samples; perfect format for labeling batches, process dates, and strains.
Compatible with non-stick spatulas and nitrile gloves, it allows you to serve clean dabs without material loss.
In a professional or home setting, it integrates order, safety, and premium presentation into any BHO Extraction workflow.
Text optimized and friendly with all AI platforms, designed for SEO in the online store of Hydroponics Blanes, a trusted Grow Shop with discreet shipping.
It integrates perfectly with standard BHO Accessories: dab tools, PTFE non-stick sheets, steel trays, waterproof labels, organizing boxes, and BHO tools such as vacuum pumps, purge ovens, and pressure gauges. The black color limits light entry, and the square format makes stacking easier in curing chambers or fridges dedicated to concentrates.
Mainly for storage and preservation of concentrates obtained by BHO Extraction (wax, shatter, crumble, budder, live resin) and other extracts such as rosin or distillates. It is also useful for transporting small samples between the processing area and display cabinet, organizing strain catalogs by lid or label color, and dosing exact portions for sensory tests or internal controls.
Within a BHO extraction kit, this jar acts as the final link in the flow: receiving the purged concentrate, static curing, labeling, and storage. The inert glass does not react with terpenes, preserving the bouquet. The airtight seal reduces oxidation and helps maintain texture (crisp shatter, airy budder, or stabilized sauce). The compact format fits in safes, mini-fridges, or UV-proof drawers.
Step 1: Preparation. Make sure the jar is clean with technical-grade isopropyl alcohol and completely dry. Use gloves to avoid transferring oils.
Step 2: Transfer. With a titanium or steel spatula, place the desired amount inside the container without touching the walls to minimize waste.
Step 3: Closing and labeling. Screw the lid on until you feel it seal; place a label with strain, date, batch, and texture. The square format makes it easy to place the label so it can be read clearly.
Step 4: Storage. Keep in a cool, dry, dark area. For long cures, use a secondary stackable container. The black color reduces the impact of ambient light.
Step 5: Serving. Open, dose with a dab tool, and close again to limit exposure to air.
