The 500 ml clear pharmaceutical glass bottle is the largest-volume member of the CGMB family. This cap-less version is for those who already have an appropriate closure — for example a custom pump, screw cap, or own-branded seal — or who want to swap between different cap types depending on the contents. The larger volume suits bulk massage-oil filling, larger lotion runs, industrial sample storage, or small-laboratory data collection. The 30-piece pack is already a serious prepared set for a small-business workshop or for launching an own-label cosmetic line.
What the pack of 30 contains
30 clear (water-white) pharmaceutical glass bottles with a nominal fill capacity of 500 ml, WITHOUT caps. Bottle height ~220 mm, diameter ~80 mm, net unit weight ~380 g; gross package weight 12.54 kg. The bottle neck is a standard size, so the other CGMB-04 cap variants (aluminium, plastic screw, black anodised aluminium, black plastic, pump) all fit it.
Clear pharmaceutical glass properties
Clear (flint) pharmaceutical glass is chemically inert, imparts no off-flavours or odours, and contains no plasticisers. Full transparency allows continuous visual control of the contents — colour, clarity, sediment, or phase separation. It is therefore ideal for lotions, bath oils, massage bases, hydrosols, and carrier oils where visual identification matters. For light-sensitive preparations (concentrated essential oils, high vitamin C), choose amber glass instead.
500 ml — the advantages of the largest volume
500 ml is the largest volume in the CGMB series, which brings several practical advantages: fewer bottles to label and fill for the same total volume, lower packaging cost per unit, and longer use time per bottle for the end customer. For massage therapists and cosmetic studios it is particularly convenient: a weekly or two-weekly amount can stay in a single bottle. It also suits industrial sample storage and small-laboratory data collection, since a representative quantity fits comfortably inside.
Areas of use
- Bulk massage-oil filling for therapeutic studios and cosmetic salons
- Larger-volume lotions, body care, and hydrosols
- Carrier-oil refill format for an own-label cosmetic line
- Industrial sample storage, small-laboratory data collection, reference bottle
- Liquid household concentrate in a 500 ml format
Choosing a cap and compatibility
Since this version ships without a cap, you will need to choose an appropriate closure separately. The other CGMB-04 variants (CGMB-04AB black anodised aluminium, CGMB-04AC silver aluminium, CGMB-04BC plastic screw, CGMB-04CR black plastic, CGMB-04PC pump) are all compatible with this bottle. If you need a secure seal, choose the aluminium-cap variant. If you need hygienic dispensing, the pump variant is ideal.
