Key Specifications

Success Story: Custom Order from a Swiss Fragrance Laboratory

Our 15ml glass tubes were chosen by a famous Swiss fragrance research laboratory which requested specific customization of PTFE-lined caps and printed graduations. The custom-designed tubes performed exceptionally well: the precise graduations reduced mixing measurement errors by 0.5%, and the tubes also increased their sample submission capacity by 40%. They initiated another order for 500,000 vials which they needed to package their new fragrance blend sets together with their concentrated essential oil items.

Customization Options

• Custom Caps: Our company provides customers with various cap options which include specific linings of silicone or rubber together with different color choices and child-safe or tamper-evident features.
• Capacity: Glass tubes are available in multiple capacities of 5ml, 30ml, 50ml and 100ml.
• Inner Coating: The glass tube uses special inner coatings which protect against both reactive and adhesive substances.
