Pure performance
Focus on MEMBRANEBLUE-DUAL®

• MembraneBlue-Dual® is a dye to stain both the ILM as well as the ERM and PVR membrane, without compromising the staining effect within one injection.
• By injecting MembraneBlue-Dual® in the vitreous cavity the membrane will be clearly stained and easily distinguished 
  from the underlying, unstained retina and can be removed selectively.
• Extensive tests proved that MembraneBlue-Dual® is a 100% stable mix and stains the ILM at the same level as ILM-Blue® and stains the ERM and PVR at a higher level than the classic MembraneBlue.
• Due to a new integrated carrier 4% PEG solution, 
  MembraneBlue-Dual® can be injected in a BSS filled eye 
  and sinks imme-diately as a cohesive ball to the fundus of
  the eye and only stains the targeted tissue without 
  diffusion throughout the whole globe.

Best ILM & ERM staining 
due to high purification up to 97% purity 

MEMBRANEBLUE-DUAL®: Dye for staining ILM, ERM & PVR membranes consists of: 

• Combination of TrypanBlue 0,15% 
  + BBG 0,025% + 4% PEG
• Highly purified TB + BBG up to 97%
• 

Best injection characteristics 
due to new "carrier" 4% PEG solution
Creates better injection characteristics under BSS.
Sinks immediately to posterior pole as a cohesive ball. 
Stains only target tissue and no diffusion throughout the eye.

Safety tests
Toxicity tests on ARPE-19 human retinal pigment epithelium 
cells showed an advantageous safety profile of the new 
products MembraneBlue-Dual®.

Increased purity of the dyes as well as the addition 
of PEG3350 results in even safer products.

Safety testing was complemented by electron microscopy 
ultrastructural analysis and in vitro cytotoxicity tests 
according to ISO-10993.
