WELCOME TO THE GATEWAY FOR TESTING SERVICES at BMT Wing - Customer Service Cell.
The Biomedical Technology Wing of the Institute, located at Poojapura Campus offers selected testing services to external customers - primarily intended for the medical device industry in the areas of Physico-chemical characterization as well as biological evaluation of materials. The testing services are coordinated by the Customer Service Cell (CSC), which is the point of all contact and communication for the external customers with the Institute.
The CSC will extend you with all support such as providing information on the testing services, testing timelines, limitations, test methods, test charges, payments etc. If required, interaction with testing laboratory will be facilitated by the CSC. Please feel free to contact the CSC for all your queries regarding testing services.
1. Characterization of materials as per international standards using analytical techniques:
2. Biological Evaluation meeting the requirements of International standards ISO 10993, ASTM & USP:
3. Preclinical Functional and Safety Evaluation of Medical Devices
Preclinical studies: Safety and functional performance evaluations in large animals are also offered as part of the testing service and the Institute possess excellent facility and expertise for the evaluation. These studies are carried out on a study mode based on a study plan/protocol which is prepared based on the requirement of the customer. Budget for the study is made and is to be paid by the sponsor. These animal studies are conducted subject to approval by the CPCSEA.
Animals provide a valuable testing system anatomically, physiologically or even pathologically because of their phylogenetic closeness to humans. Preclinical large animal evaluation is generally conducted in order to provide a reasonable assurance of device safety prior to use in humans in a clinical trial. Relevant animal models are selected depending on the clinical application of the device.
Experience & expertise in the evaluation of critical cardiovascular & neurosurgical products and sophisticated facilities is a good advantage to us.
Expertise include evaluation of majority of the cardiovascular devices like drug eluting coronary stents, heart valve etc.
The manufacturer must ensure the product and package system combine to create a total product that performs efficiently, safely and effectively in the hands of the user.
Accelerated aging is the storing of packages at elevated temperature and / or other intensified environmental conditions in order to simulate real time aging in a smaller duration of time. Environmental chambers are used for accelerated aging test.
The principle behind the concept of accelerated ageing is that the ageing of medical device packaging can be accelerated to two time space by increasing the storage temperature by 10oC, by what is known as Q10 analysis.
The ageing studies are carried out on the basis of the following:
• Donald S Barcan and Harold F Miller, Package Validation in Max Sherman (Ed.), Medical Device Packaging Handbook, Marcel Dekker Inc, NY, 1998, pp267-30
• The European Agency for the Evaluation of Medicinal Products. Guideline for stability testing : stability testing of existing active substances and related finished products, CPMP/QWP/122/02 rev 01 , Dec 2003

What Every Test Request Should Have
Our Quality management system for testing services confirms to the international standard ISO/IEC 17025: "General requirements for the competence of testing and calibration laboratories".
About twenty biological tests which includes biocompatibility testing also are accredited by Le Comite Francais d'Acreditation (COFRAC) of France. The test reports of all accredited tests are issued with the COFRAC logo.
Calibration services (mechanical and thermal calibration) is accredited by National Accreditation Board for Testing & Calibration Laboratories (NABL).
Biocompatibility testing and evaluation of medical devices is performed to determine the potential toxicity resulting from contact of the device with the body. The device materials should not-either directly or through the release of their material constituents-produce adverse local or systemic effects, be carcinogenic, or produce adverse reproductive and developmental effects.
The biological evaluation of any material or medical device intended for use in humans shall form part of a structured biological evaluation programme within a risk management process in accordance with ISO 14971 as set out in the figur
As per ISO 10993 the choice of tests and the data required in a biological evaluation and their interpretation shall take into account the chemical composition of the materials, including the conditions of exposure as well as the nature, degree, frequency and duration of exposure of the medical device or its constituents to the body, enabling the categorization of devices to facilitate the selection of appropriate tests.
The biological evaluation performed based on ISO 10993 categorizes medical devices according to:
Material characterization is the crucial first step in the biological evaluation process. The extend of chemical characterization depends on what pre-clinical and clinical safety and toxicological data exist, and on the nature and duration of body contact with the medical device, but as a minimum the characterization shall address the constituent chemicals of the device and constituent residual process aids or additives used in its manufacture.
The following material characterization facilities are available :
This guideline is prepared to help you understand the importance of proper "sample preparation" for the different tests performed for the biological evaluation of materials.
It must be noted that testing is to be performed on the final product, or on representative samples taken from the final product or from materials processed in the same manner as the final product.
Submitting proper samples will go a long way in ensuring that you get the proper test reports in time.
We strongly advise you to visit us and discuss your testing requirements and get first hand information on the sample requirements for the selected tests; especially if you plan to submit the test reports to any regulatory agency.
We conduct tests on the samples submitted by you and the test results provide results for the test samples only. We do not certify your batch or product quality.
Our test reports will specify the test material/sample code as mentioned by you in the test request forms. Kindly ensure that you have specified the proper sample code that will reflect your end use. If you are submitting the test reports to a regulatory agency, ensure that the test sample codes will provide unambiguous traceability to your material/product. We will not accept requests for change of test sample codes or other details such as name of company etc. on the test report after testing.
1. Contact the lab and understand the specific requirements beforehand
2. Follow the specific instructions on each test request form
3. Submit samples in separately marked packets for different tests
4. When replicates are required, pack the samples in separate individual packets
5. Label the packets correctly
6. Indicate the sterilization status- whether sterile and method of sterilization
7. Indicate clearly, special storage conditions if any for your sample
8. Do indicate shelf life of samples when the sample is unstable or has a limited shelf life only
9. Do submit appropriate CONTROL samples, if required as part of the study/test.
10. If test materials are to be archived then a special request need to be given. Test materials will be archived for a maximum of 3 years.
1. Do not submit samples with hazardous / infectious/ radioactive content.
2. Don't have sharp and pointed edges for your samples. Remove any burrs or sharp edges from the sample pieces.
3. Don't submit samples before prior intimation to the customer service cell, either by post or in person.
4. Don't mix samples for different tests together. Pack the samples for different tests separately.
5. Do not use staplers or pins on sterile packets. If sending by post/courier, ensure that there is no damage due to stapling by the courier agency.
