Best Microbiology testing lab in Mumbai
Cytotoxicity Studies
In vitro Cytotoxicity testing are rapid, standardized, sensitive, and inexpensive means to detect cell damaging substance present in the sample material. Cytotoxicity tests are considered screening assays, used to evaluate the living cell’s reaction to the implant in a cell culture assay. The test is suitable for sportsewear, underwears, wellness and functional textiles, babycare products as well as Medical products. This represents “Skin Friendliness” or Biocompatibility of Materials.
This is carried out by ISO 10993-5 standard using L 929 cells. Extraction, Direct Contact and Agar Overlay method are the procedures to determine presence/ absence of biologically harmful constituents.
Virology BSL-3 Lab
With the current scenario where a lot of viruses pose a threat to humanity, there has risen a need to counter these entities so that they can be neutralized before causing adverse effects to human life. In that sense,
Biotech Testing Services has a fully functional BSL-3 Virology laboratory to carry out antiviral activity of textiles, plastics, metals and similar non-porous materials and Sanitizer/ Disinfectants.
We are one-of-a-kind laboratory in India to evaluate performance of product using live virus particles by determining viral titre by TCID50 and Plaque assay methods. The most widely accepted methods like ISO 18184, ISO 21702, ASTM E 1052, ASTM E 1053 and EN 14476 are used to determine susceptibility of viruses to chemical disinfectants/ Treated substrates.
Virus Penetration / Blood Penetration
This test method is used to evaluate the resistance of Protective clothing to penetration by blood-borne pathogens/ blood and body fluids.
This test method uses a surrogate microbe under conditions of continuous liquid. Protective clothing “pass/fail” determinations are based on the detection of viral penetration at a specific hydrostatic pressure using the specially designed Test apparatus. The same way, protection against blood and body fluids is determined using synthetic blood.
ISO 16604/ ASTM F 1671 are widely used for penetration by blood-borne pathogens and ISO 16603/ ASTM F 1670 are used for penetration by blood and body fluids
Resistance of Paints to Algal & Fungal growth using Environmental Chambers
Fungal growth, frequently referred to as mildew, causes defacement of paint films exposed to varying Environmental conditions. To evaluate this, painted panels are exposed for 4-week period to accelerated conditions in Environmental Chambers having green house soil supporting abundant Fungal sporulation. The visual rating of paint surface signifies its Resistance/ Susceptibility to Fungal attack. ASTM D 3273/
Algal growth on Paints is undesirable wrt aesthetics/ hygiene. Controlling Algal growth is a tedious task owing to the fact that it has very limited nutritional requirement and are prevalent in tropical / rain prone climates.
Evaluation of algae on real time basis is time consuming and impractical. Hence use of Algal Chambers is useful in evaluating the degree and permanency of protection against surface growth of algae.This method is reliable in predicting Algal resistance/ susceptibility under laboratory conditions due to the continuous exposure to consortium of algal spray under artificial illumination.
