2. Biological safety cabinet-Class II
Make : Labline
Application :A biosafety cabinet (BSC)—also called a biological safety cabinet or microbiological safety cabinet—is an enclosed, ventilated laboratory workspace for safely working with materials contaminated with (or potentially contaminated with) pathogens requiring a defined biosafety level
Standard Features: The primary purpose of a BSC is to serve as a means to protect the laboratory worker and the surrounding environment from pathogens. All exhaust air is HEPA-filtered as it exits the biosafety cabinet, removing harmful bacteria and viruses.
Unique Features and Advantages :Class II cabinets provide both kinds of protection (of the samples and of the environment) since makeup air is also HEPA-filtered.

Application : “(i) Blaine’s air permeability apparatus conforming to IS 5516 is used to determine the fineness of cement in terms of specific surface area. Fineness test is used to check the proper grinding of cement and measures the surface area of the cement particles per unit mass.
(ii) Le Chatelier apparatus conforming to IS 5514 is used to determine the soundness of cement due to the presence of lime. The test procedure consists of subjecting a sample of cement to a controlled heating, then measure its expansion for estimate the possible risk of late expansion due to hydration of free lime.
(iii) Vicat apparatus conforming to IS 5513 is used to measure the standard consistency and setting time of cement. Standard consistency test is conducted to find out the amount of water to be added to the cement to get a paste of normal consistency. Initial setting time is the time elapsed between the moments that the water is added to the cement, to the time that the paste starts losing its plasticity. The final setting time is the time elapsed between the moment water is added to the cement and the time when the paste has completely lost its plasticity and has attained sufficient firmness to resist certain definite pressure.
(iv) Le Chatelier flask is used to determine the specific gravity of cement. Specific gravity is the comparison of the mass or density of any substance with the mass or density of the standard substance (water). Specific gravity of cement is an essential parameter in concrete mix design and quantity estimations.
(v) Compressive strength of cement is estimated by conducting compression test on standard mortar cube of face area 50 sq.cm. after 7 and 28 days of curing. Compression testing machine of capacity 3000kN is used to carry out the compression test.
