It is the core part of the laboratory, which mainly provides protection for samples and ensures the accuracy of experimental results and the safety of personnel.
(1) sterile room
Sterile room provides a relatively sterile working environment for microbial experiments through air purification and space disinfection. The main components of the sterile room are air self-purifier, transmission window, ultraviolet lamp and so on. A strict sterile room may also be equipped with a wind room.
(2) Clean the workbench
As a kind of equipment to replace aseptic room, clean workbench is simple and convenient to use, which provides a relatively sterile operating platform for experiments. Ultra-clean work Taiwan Province team is divided into horizontal and vertical teams according to the wind direction.
Second, the incubator
It is mainly used for the cultivation of microorganisms in the laboratory to provide a suitable environment for the growth of microorganisms.
(1) General incubator: The temperature range generally controlled is: room temperature +5 ~ 65 degrees, which is divided into electrothermal constant temperature incubator and waterproof constant temperature incubator.
(2) Biochemical incubator: Generally, the controlled temperature range is 5 ~ 50 degrees.
(3) Constant temperature and humidity box: generally, the temperature range is 5 ~ 50 degrees, and the humidity range is 50 ~ 90%. Can be used as a mold incubator.
(4) Anaerobic incubator: suitable for the cultivation of anaerobic microorganisms.
Electric drying oven: used for dry heat, sterilization and baking of straws and flat glassware.
4. Autoclave sterilizer (also called autoclave): Sterilize articles.
5. Balance: An analytical balance with the accuracy of110000 is generally required.
6. Microscope: an essential instrument for observing the morphology and dynamics of bacteria, and the structure of microorganisms and tiny objects.
Spectrophotometer: QS is used to produce instant noodles, tea drinks, meat products, dairy products and marshmallows.
8. Acidimeter: QS is used to produce canned fruits and vegetables, sugar and drinking water.
9. Conductivity meter and turbidity meter: QS enterprise is used to produce drinking water.
X. Refractometer: QS is used in enterprises that produce canned fruits, vegetables and drinks.
Eleven, constant temperature water bath pot: used for QS some enterprises that need water bath (such as Escherichia coli test) to produce instant noodles and quick-frozen noodle products.
12. Nitrogen fixation device: QS is used for enterprises producing dairy products and beverages containing protein.
Impurity filter: used in QS for dairy enterprises.
Homogenizer: used to homogenize samples. There are two options: rotating blade type and flapping type.
Traditional glassware
1. Suction tube: used to suck a small amount of liquid. Commonly used straws are 1 graduated 1mL and 1 graduated 10mL.
2. Petri dish: it is a kind of hard glass double-layer Petri dish, which is often used for separation and culture. The size of the cover and bottom should be appropriate, and the common specification is 90 mm
Three, triangle flask and jar: mostly used for holding culture medium and preparing solution, commonly used specifications are 250mL, 500mL, 1000mL.
Four. Beaker: used for holding liquid or boiling. Commonly used specifications are 100mL, 250mL, 500mL, 1000mL.
Verb (abbreviation of verb) measuring cylinder: used for liquid measurement. The common specifications are 100mL, 250mL, 1000mL.
Six, test tube: used for bacterial culture, there are many specifications.
Seven, slide cover: bacterial smear observation.
Eight, reagent bottle: used as a reagent, generally brown to avoid light.
Others, such as test tubes, brushes, alcohol lamps, inoculation needles, inoculation rings, etc.
Laboratory support general equipment
A, fume hood
Second, centrifuges.
Third, the water purifier
Fourth, the oven
Five, low-temperature refrigerator laboratory commonly used consumables (purification workbench)
Intransitive verb others
