Lab equipment for biology

First, it should be clear that biological lab have different focuses and classifications, such as microbiology lab, cell biology lab, molecular biology lab, and tissue culture lab. According to different biological lab, the commonly used lab equipments are also different.

Commonly used lab equipments in the microbiology laboratory are:

Constant temperature incubator, mold incubator, biochemical incubator, ultra-clean workbench, autoclave, oven, heating plate, electric furnace, electronic analytical balance, magnetic stirrer, water bath, shaker, Centrifuge, cryopreservation box, pipette, PH meter, spectrophotometer, optical microscope, scanning microscope, homogenizer, etc.

Commonly used lab equipments in molecular biology and cell biology lab are:

Carbon dioxide incubator, biological safety cabinet, low temperature storage box, oven, autoclave, analytical balance, ordinary balance, pipette, centrifuge, inverted microscope, PCR equipment, electrophoresis equipment, decolorizing shaker, etc.

Commonly used lab equipments in tissue culture lab are:

Autoclave, oven, shaker, light incubator, artificial climate incubator, analytical balance, ordinary balance, ultra-clean workbench, etc.

From the perspective of laboratory workflow, it is divided into sample storage, sample preparation, cultivation process, observation and analysis. Different equipments are required in different working steps.

In general, commonly used equipments for sample storage include refrigerators/ultra-low temperature refrigerators and liquid nitrogen tanks. Common equipments for sample preparation include pipettes, balances, homogenization/stirring series, centrifuges, freeze dryers, autoclaves, and electrophoresis equipments.

Commonly used equipments in the cultivation process include incubator series, biological safety cabinet/ultra-clean workbench, fermentation tank, shaker, water bath, bottle turning machine, PCR equipment, microplate reader, etc.

Commonly used equipments for observation and analysis are microscopes, colony counters, flow cytometers, DNA sequencers, and chromatography series.

In the biological laboratory, equipments such as bottle washer, ultra-pure water series, and ultrasonic cleaning machine may also be used.

Lab equipment for physics

Commonly used in physical laboratory equipment are:
(1) Basic measuring tools and equipments, such as meter ruler, vernier caliper, micrometer, balance, spring scale, metronome, dot timer, thermometer, measuring cylinder, barometer, teaching electric meter, ammeter, voltmeter, multimeter, oscilloscope, Signal generator, etc.;
(2) General equipments, such as projectors, movie machines, magnetic teaching boards, vacuum pumps, physical supports, power regulators, etc.
(3) Special equipments, such as Archimedes tester, Torri deli tester, connecting device, pulley and pulley block, calorimeter, electroscope, electrostatic induction motor, sliding wire rheostat, rheostat box, low voltage power supply, Magnets and needles, primary and secondary coils, induction coils, relays, prisms, optical benches, lenses, spectral tubes, X-ray tubes, Wilson cloud chambers, etc.

Management of laboratory equipment

1. To establish equipment and equipment files

The laboratory must establish a file for each equipment, establish a "file" and prepare an "equipment and equipment list" account book, for easy reference and tracking. The content includes: uniform number of equipment, equipment name, model, technical indicators (range, accuracy, etc.), manufacturer, factory number and date, purchase time, performance status, verification or calibration cycle (certificate), maintenance status, use or the custodian, the current position, etc., to achieve one machine and one file.

2. Ensure the normal operation of the equipment

It is necessary to standardize the operating procedures of equipments and equipment, and each laboratory testing equipment should prepare "operation instructions"; implement environmental monitoring on the equipments and equipment, establish use registration and temperature and humidity monitoring records, and find faults in a timely manner to eliminate the fault and make the equipment The operation of the equipment is always under control and running normally.

3. Verification during the implementation of equipments and equipment

For equipments with high frequency of use, parameters that are easy to drift, often disassembled, transported, and carried to the site for testing, consideration should be given to check during the arrangement period when appropriate. During the implementation, verification is different from calibration. Calibration is to verify and correct the performance of the equipment between the two calibrations. Calibration solves the "quasi-inaccuracy" of the equipment; while the verification of the equipment during the implementation of the equipment solves the "stability" of the equipment problem.

4. The signs of the lab equipment should be managed

Implement label management for equipments and equipment, using green, yellow, and red status signs, and equipments and equipment that pass verification or calibration use green (for normal or grid) marks; when the accuracy of a certain range of equipments and equipment is unqualified, but used for testing When the partial range is qualified or degraded, the yellow mark is used; the damaged or unqualified equipments and equipment use the deactivation mark.
