SITRA Textile Chemistry Division is the one of the oldest divisions of SITRA and it provides accurate, reliable and faster testing services for fibre, yarn, fabric, garment, accessories, packing materials, oil, sizing ingredients, chemicals, technical textile, water, textile effluent and soil / sludge samples using national and international standard test methods.
With 4 decades of experience and skilled manpower, SITRA Textile Chemistry Division has theexpertise to meet the ever increasing demands of today’s industry. SITRA’s test reports are valid across the globe! The laboratory is accredited by the National Accreditation Board for Testing and Calibration Laboratories as per ISO / IEC 17025 : 2017 vide certificate no. TC 6944.
With our lab working in shifts, we are able to provide the test reports to customers quickly and ensure swift turnaround time. Our online Laboratory Information Management System (LIMS) enables the customers to track the status of their samples, view the results and take print-outs of their respective test reports online.
