Must be equipped in a level 2 bio lab?
Basic Configuration of Level II Biosafety Laboratory
(1) Laboratory bench: Whether it is a level II biosafety laboratory, or other types of laboratories, the laboratory bench is indispensable, the relevant equipment and supplies are placed here. Its countertop material to acid and alkali resistance of the physical and chemical solid core board is appropriate, under the countertop drawers and cabinets to place the experimental supplies.
(2) safety cabinets: the safety cabinets for biological safety cabinets, according to national norms, the second level of biological safety laboratories must be configured with a safety cabinet. This is a kind of isolation equipment, the role is to prevent the proliferation of harmful suspended particles in the laboratory, can provide comprehensive protection of staff, experimental samples, the environment in the laboratory.
(3) interlocking transfer window: according to national norms, the second level of biosafety laboratories must be configured with two interlocking transfer window to ensure the safety of logistics. There should be ultraviolet lamps inside the transfer windows to sterilize the items entering the laboratory.
(4) interlocking doors: according to national norms, the secondary biological safety laboratory must be configured with a set of interlocking doors, interlocking doors, 1 door is not closed, it is not possible to open the other door, thus playing a buffer effect of airflow.
(5) automatic door closers: automatic door closers must be installed on the door of the secondary biological safety laboratory.
(6) Scrubbing table: in the secondary biosafety laboratory scrub disinfection room to be equipped with a scrubbing table, and the water should be used in the laboratory triple water, sinks and downstream hoses to be used in acid and alkali resistant PP materials.
(7) multifunctional microcomputer controller: the temperature and humidity display and control of the secondary biological safety laboratory, send and exhaust fan start and stop and start and stop sequence, lighting switches, ultraviolet lamp control, these are controlled by multifunctional microcomputer controller.
(8) micro-pressure differential meter: according to national norms, two biological safety laboratories must be equipped with a set of indoor and outdoor pressure differential amount of indoor and outdoor pressure difference, and control of differential pressure micro-pressure differential meter.
(9) ultraviolet lamp: biosafety laboratories must be equipped with 2 ultraviolet lamps in order to provide physical disinfection for staff.
(10) socket: the laboratory must have a socket, the second level of biosafety laboratories are no exception, to configure a sufficient number of nine-hole sockets and three-phase four-hole socket to be able to do, and sockets are embedded design.
Does the chemical industry use computers?
Many.
Aspen, CAD, SmartPlant3D, MATLAB, ChemDraw, Origin and other software used in chemical engineering majors require high computer configurations. You need to pay extra attention when choosing a laptop.
CAD is the most commonly used drawing software, mainly used to draw construction design drawings, process flow diagrams, etc. Aspen is mainly used to simulate the entire process of chemical production, SmartPlant3D is mainly used to design and optimize the chemical production process. MATLAB, Origin and other software is mainly used to calculate and analyze data.
How to configure the canonical liquid for biological experiments?
Measure 35-40mL of prepared iodine standard titration solution, place it in an iodine measuring flask, and add 150mL of water (15-20℃). Titrate with sodium thiosulfate standard titration solution, near the end point, add 2mL starch indicator (10g/L), continue titration until the solution disappears blue. At the same time to do a blank test.
Dilute iodine solution: take the original iodine solution 2mL, add potassium iodide 20g, mix, add purified water to dissolve the capacity to 500mL, stored in a brown bottle.
Types of health information?
Medical informatics, MI (Medicineinformation) is the combined science of medicine and computer science, is a necessary stage of medical development. It is an emerging interdisciplinary discipline. Medical informatics was first applied to basic research, clinical practice, hospital management, and now extends to regional health information systems, national health information network.
Medical informatics (also known as health informatics or medical informatics), is an interdisciplinary discipline of information science, medicine and health care. It studies relevant resources, designs and methods to optimize the acquisition, storage, retrieval and utilization of health and biomedical information. Medical informatics, as an emerging cutting-edge interdisciplinary field, uses tools that include not only computers and informatics technologies, but also clinical guidelines, appropriate medical terminology, and information communication systems as implementation platforms.
Medical informatics includes a number of subordinate subfields, such as: bioinformatics, pharmacoinformatics, public **** health informatics, and medical graphic informatics.
Recommended computers for bioscience majors?
Personal analysis
One, to the biological sciences, buy laptop computers and do not have to be too good configuration, after all, do not have to be involved in the graphic design, design a class, so the ordinary G series of dual-core CPU or I3 series of CPU computers are enough to use.
Two, if they are not for professional and buy a computer (for example, also play games), then you should buy a good point of configuration, so you can not delay.
Specific recommendations, Asus, Dell, Lenovo and other brands of laptops.
Recommended configuration: i5 series processor 4G memory 500G hard disk 2G unique display.
