The Series 5572 is the tallest bottle in our amber dropper family, a slim 30 ml-class cylinder designed for essential oil brands, aromatherapy blenders, and private-label skincare companies that need a dependable retail-size hero SKU. The bottle itself is a plain cylinder: deep amber glass, a straight-sided cylindrical body, a gently sloped shoulder, and a continuous-thread neck ready to accept standard dropper assemblies. If your product line is built around a 30 ml flagship oil, a facial serum, or a beard oil sold at full retail price, this is the format most of your competitors already sit in — and the one your filling line will thank you for choosing.

Why the 30 ml Cylinder Owns the Retail Shelf

Thirty millilitres is the de facto standard retail unit for single-note essential oils and facial treatment oils across North America and Europe. It is large enough to carry a premium price point and a full ingredient story on the label, yet small enough that a customer finishes the bottle before oxidation degrades a sensitive blend. The Series 5572 body proportions are tuned to that role: the tall, narrow cylinder maximizes shelf presence per centimetre of footprint, gives label designers a generous flat wrap area for front-panel branding and a compliant back panel, and stacks efficiently in retail trays and e-commerce mailers. Compared with squat boston rounds of the same capacity, the cylinder silhouette reads more clinical and modern, which suits dermocosmetic and apothecary-positioned brands.

The straight wall also simplifies decoration. Silk-screen printing, hot stamping, and full-wrap pressure-sensitive labels all apply evenly without the panel distortion you fight on curved shoulders. If you plan a matte black or gold screen print directly on the amber glass, the flat body is the friendliest canvas in the dropper category.

Neck Finish and Dropper Assembly Pairing

The mouth shown in the photo is a continuous-thread finish in the DIN 18 class, the global standard for dropper bottles in this capacity range. That single decision unlocks a wide closure ecosystem: glass pipette droppers with nitrile or silicone bulbs, tamper-evident dropper caps for pharmacy-channel products, child-resistant dropper closures for blends containing restricted essential oils, and orifice reducers with screw caps if a SKU ships without a pipette. Pipette length must be matched to bottle height so the tip reaches the last millilitres without bottoming out on the push-up of the base; we supply matched assemblies so the pipette, bulb, and cap are validated together. Exact neck dimensions and thread profile are confirmed on the technical drawing at quotation, and we encourage buyers to validate their existing closures against our drawing before committing to a full production run.

Filling-Line Compatibility: Where This Bottle Earns Its Keep

A 30 ml retail SKU is usually the highest-volume item in an oil brand’s catalogue, which means it spends the most hours on the filling line. The Series 5572 is engineered around that reality. The cylindrical body transfers cleanly through star wheels and timing screws without the rocking that round-shouldered bottles exhibit at speed. The flat, thick base gives stable puck-less conveying on standard tabletop chains, and the rigid neck ring tolerates the gripper pressure of automatic capping heads set for dropper caps. Amber glass of this wall thickness handles the thermal shock of warm-fill processes for oil-wax blends within normal cosmetic filling temperatures.

For contract fillers running volumetric piston or peristaltic fillers, the narrow bore of the DIN 18 finish accepts standard filling nozzles with minimal drip-back. We recommend a short trial on your line with production samples — available before mass production — to confirm torque windows, labeler registration, and case-packing orientation. Buyers who ship filled product into Amazon FBA or third-party fulfilment centres should also note that the 30 ml cylinder nests efficiently in standard twelve-count master cartons, which reduces dimensional-weight charges compared with wider-shouldered formats. Brands that are still planning their supply chain can review our guide to importing glass bottles from China for lead-time, Incoterms, and logistics expectations before placing the first purchase order.

Quality Control and Compliance

Every production lot of Series 5572 passes a documented QC protocol before it leaves the factory. Annealing stress is verified by polariscope inspection in line with ASTM C148, so the bottles resist spontaneous breakage during filling, capping, and transit. Internal pressure resistance is tested per ISO 7458, and thermal shock endurance is verified per ISO 7459, covering the temperature swings of warehouse storage and container shipping. Verticality, wall-thickness distribution, and brimful capacity are gauged on statistical samples from each mould cavity.

For cosmetic applications, packaging must not adulterate the formula under normal use. Our amber soda-lime glass is produced to support your compliance obligations under EU Cosmetics Regulation (EC) No 1223/2009, and we provide material declarations and migration-relevant documentation on request so your safety assessor can complete the product information file. UV transmission data for the amber glass is available with the quotation package.

Ordering: MOQ, Samples, and Customization

Standard amber Series 5572 bottles run from stock moulds, which keeps minimum order quantities practical for indie brands and contract fillers alike; the current MOQ logic is explained in detail on our glass bottle MOQ page. Pre-production samples with your chosen dropper assembly are strongly recommended and ship within days. Customization options include silk-screen printing, hot stamping, frosting, and custom colour coatings, plus matched cartons and dividers for e-commerce fulfilment. To receive a quotation with the technical drawing, closure options, and current lead time, send your target annual volume and closure preference through our contact page and our team will respond with a complete package.

Frequently Asked Questions

What is the minimum order quantity for the Series 5572 amber dropper bottle?

As a stock-mould item, the 5572 typically starts at 10,000 pieces per order for plain amber bottles, with lower trial quantities negotiable for first-time buyers. Decorated orders (silk-screen or frosting) may carry a higher MOQ per design. Send your target volume through our contact form and we will confirm the exact figure with your quotation.

Can I get samples with a dropper cap before placing a production order?

Yes. We ship free bottle samples with your choice of pipette dropper, tamper-evident cap, or child-resistant closure; you only cover the courier cost. Samples ship within 3-5 working days so you can test filling, dosing feel, and label fit before committing.

Which dropper assemblies fit the 5572 neck finish?

The bottle uses a DIN 18-class continuous-thread finish, compatible with standard glass pipette droppers (nitrile or silicone bulb), tamper-evident dropper caps, child-resistant dropper closures, and orifice reducers. Pipette length is matched to the bottle height; confirm exact dimensions on the technical drawing at quotation.

Is the amber glass compatible with essential oils and facial serums?

Amber soda-lime glass is chemically inert against essential oils, carrier oils, and typical serum bases, and its UV filtering protects light-sensitive actives. For aggressive formulas such as high-acid or high-alcohol products, we recommend a 4-12 week compatibility and stability test with your bulk before mass filling.

What is the lead time for a 30 ml dropper bottle order?

Plain amber bottles from stock moulds typically ship 25-35 days after deposit and drawing approval. Add roughly 10-15 days for silk-screen printing or other decoration, and confirm sea or air freight timing with your forwarder based on the destination port.

Yes. Options include one- to multi-colour silk-screen printing, hot stamping, matte frosting, spray colour coating, and custom droppers with coloured bulbs or collars. Share your artwork and Pantone references and we will produce a decorated pre-production sample for approval.
