Glass Serum Bottles — Dropper or Pump, 2ml to 120ml
Serum bottles are small glass bottles with a dropper or pump, and RENTRASPA™ stocks them from 2 ml sample vials to 120 ml bottles. Choose a pipette, press-button or euro dropper, or a lotion pump, in amber, clear, frosted, blue, green, black or painted glass. 30 ml is the usual face-serum size. Order one piece to test, or buy wholesale with no minimum order.
Frequently Asked Questions
-
A dropper bottle, or pipette bottle: a glass bottle with a glass pipette and a rubber teat set in a screw collar. Essential-oil bottles use a euro dropper instead, a plastic insert that releases one drop at a time under a screw cap. RENTRASPA™ stocks both, from 2ml to 120ml, with collars in gold, silver, black and white. Compare every style in glass dropper bottles.
-
30ml is the standard, about two to three months of daily use. 15ml suits trial packs and high-value actives; 50ml and 100ml suit hair oils and body oils; 2ml and 3ml vials are for samples and testers. Most round bottles here share the 18mm neck, so droppers and pumps swap between sizes; press-button and designer bottles take their own matching closures.
-
Glass. It is inert, so it neither absorbs your oil nor gives anything back to it; amber, blue, green and black glass filter light; and glass reads as premium on the shelf. Plastic droppers are lighter but can hold scent and cloud over time. RENTRASPA™ stocks only glass.
-
Amber blocks most UV and is the safe default for vitamin C, retinol and essential oils. Cobalt blue and green filter part of the spectrum and are chosen for their look. Black blocks light completely. Clear and frosted clear are for stable formulas where the colour of the product sells it.
-
Pipette dropper for thin serums and oils where the customer measures drops; press-button dropper for a one-hand, premium feel; pump for thicker gels and emulsions and for hygiene, because nothing touches the product; euro dropper for essential oils. All four closures are available on the same bottle sizes, so decide by formula, not by bottle.
-
Roughly 600 drops of a water-thin serum (about 20 drops per ml) and 400–500 of an oil, which drips heavier. A standard pipette draws about 1ml — 20 to 25 drops — per squeeze.
-
It is the closure, not the oil, that decides this. A euro dropper with its screw cap seals tight and dispenses drop by drop without dripping — the format for couriered oils. A pump with a travel lock is the choice for viscous oils. A pipette dropper is a shelf bottle: it seals well but is not made for a bag or a parcel. Test one sample with your formula before you commit — RENTRASPA™ sells singles for exactly that.
-
No. Order one piece to check the fit and feel, small packs for launch batches, or wholesale quantities at the tiered price shown on every product page. Custom printing, painting and colour-matched caps start from 1,000 pieces.
-
Yes. RENTRASPA™ imports and holds stock in Chennai and ships across India on a GST invoice. Bulk prices are on each product page; for pallet quantities or a mixed order across sizes, send the quantities on WhatsApp (+91 75500 42423) for a quote.

They arrive straight from the factory cartons — new, but not washed or sterilised. Wash and sterilise every component (bottle, pipette, teat, collar, pump) before filling. Glass tolerates hot water and isopropyl alcohol; rinse with filtered or distilled water and air-dry fully.
