Coated glass vial for lyophilized injectable drugs

Lyophilization is an essential process in the biopharmaceutical industry, accelerating a drug’s time-to-market cycle and increasing shelf-life stability. But vial lyophilization can cause fogging of the glass container, which can lead to problems in the crucial inspection stage of drug manufacture.

SCHOTT TopLyo® vials feature a chemically uniform hydrophobic coating, which results in a decrease in fogging during the lyophilization process, as well as less disruption of the lyo cake. This improves the efficiency of automated inspection, leading to greater patient safety. In addition, SCHOTT TopLyo® vials offer reduced residual drug volumes and higher dosing accuracy after reconstitution.

Please note that TopLyo® vials are not meant for long-term liquid storage. Besides that short interaction with the liquid drug/formulation during the lyophilization process and reconstitution does not affect the functionality of TopLyo®.


  • Lower residual volume leads to cost reduction due to decreased overfilling.
  • Elimination of lyo cake disruption and sidewall fogging for improved automated inspection.
  • Lyo vial cake remains stable during transportation.
  • Reduced risks of protein aggregation compared to siliconized vials.
  • Product manufactured according to relevant international norms and standards
  • Product registered at Regulatory Authorities as e.g. US FDA and China NMPA (and available for Pharmaceutical Registration Applications)
Chemical Resistance
  • SCHOTT TopLyo® vials have a Si-O-C-H hydrophobic density coating of ~40 nm.
  • The stability of this layer during storage has been proven by accelerated aging at 40 0C and room temperature after three years. 
  • For production control, the standard Hydrolytic Resistance test is a release criteria, involving 0.5h autoclaving at 121 °C with H2O.
Dimensions & Cosmetics
  • Tight geometric tolerances thanks to 100% camera inspection of dimensional and cosmetic parameters along the process line.
  • Strict AQLs, with cosmetic defects a key part of the product specification. Any containers with critical defects are not allowed in the lot. 
Possible Applications
Improved lyo vial cake

Reduced climbing at vial edges results in less disruption and production losses of the lyo cake.

Optimized yield

Residual volume after reconstitution minimized by reduced adsorption at the inner glass surface. 

No dimensional changes required

Very thin coating layer of ~40 nm means no dimensional changes needed. 

Reduction of vial fogging caused by Marangoni flow
  • Chemically uniform hydrophobic coating decreases fogging during lyophilization. 
  • Reduced residual drug volumes and higher dosing accuracy after reconstitution. 
  • SCHOTT TopLyo® vials are manufactured according to all relevant international guidelines and standards. 
  • SCHOTT TopLyo® vials are registered with the US FDA and China NMPA regulatory authorities, as well as being available for pharmaceutical registration applications.
