PiStar Discontinuation Announcement: 01 November 2018


The PiStar platform of circular dichroism stopped-flow systems served and continues to aid scientists throughout the world. However, the natural evolution of our current Chirascan and SX20 products meant that official production of the PiStar platform ceased in 2006. In recent years, rather than increase your costs for parts and service, we have maintained our standard fees. However, we are now faced with the reality that several of our sub-suppliers are no longer able to manufacture many of the replacement parts for the PiStar platform. We have therefore taken the decision to withdraw support for the PiStar platform over the coming twelve months.

Total end of support for the PiStar platform will occur no later than October 31, 2019.

What does this mean for you?

  • Service visits and contract products for the PiStar platform are no longer available, effective immediately.
  • Limited support from the Applied Photophysics helpdesk will be available until the total end of support date, at which point all support will be withdrawn.
  • Orders for spare parts that are PiStar specific will be fulfilled subject to availability until the total end of support date. Orders for service parts that are common to our current platforms will not be affected and will continue to be taken after the total end of support date. This also includes product manuals.

We appreciate the custom that our PiStar customers have brought us over the years and appreciate that some of you have already migrated to our other platforms. If you would like to discuss how a new Applied Photophysics instrument can satisfy your circular dichroism and/or stopped-flow needs, or should you need advice, helpdesk support or service parts before the end of support date, then please contact us here.

We sincerely regret having to make this decision and apologise for the inconvenience and disruption that it may cause. Please do not hesitate to contact us if you are unsure of what to do next, we are here to help you, and work with you, to find the best solution for you moving forwards.
