This is to state that Simca Laboratories Pvt ltd (A WHO GMP certified pharmaceutical Company, based in Byasi, Bhaktapur,Kathmandu, Nepal) is using Stability Chambers from Osworld Scientific Equipments Pvt. Ltd. (OSEPL) (800 litres and 1000 litres) since the year 2013. Though installed almost six years, we have not come across any major problems in the machine and both the chambers are working well till date. The service of (OSEPL) is satisfactory and we believe it will strengthen further in the coming years as they have authorized Eden Technologies as their service partners. There is no doubt that the performance as well as after-sales service for OSEPL product is as per the expectations of customers.
