How to purchase laboratory testing equipment for food enterprises?

Commonly used items for microbial testing items (food, drugs, medical devices, microbial sterility testing).

The facilities and equipment of the microbiological testing laboratory are the material basis and guarantee for carrying out microbial testing. Therefore, carrying out microbial testing experiments is inseparable from laboratory facilities and equipment. The facilities and equipment of the microbiological testing laboratory mainly include:

1. Ensure the aseptic environment facilities and instruments for testing - such as clean room (sterile room), aseptic isolation system, purification workbench, etc.;

2. Ensure the sterility (sterilization) facilities or equipment of experimental supplies and utensils for testing - such as autoclaves (or manual pressure steam sterilizers), electric constant temperature drying ovens, etc.;

3. Constant temperature equipment to ensure that microorganisms can grow at a constant temperature and preserve strains in the detection - such as constant temperature incubators and refrigerators; Instruments used in various experimental operations - fully enclosed membrane filtration device, electric homogenizer, electric constant temperature water bath, centrifuge, balance, microscope, etc.;

4. Glassware used in experimental operation - all kinds of graduated straws, pipettes, volumetric flasks, test tubes, triangular flasks, double-dish petri dishes and other commonly used glassware;

5. Relevant measuring instruments to ensure the measurement of microbial colony number or inhibition diameter in various samples - such as airborne microbial sampler, airborne particle counter, multi-functional microbial automatic measurement analyzer, etc.

6. Pharmaceutical factories also test instruments and utensils for bacterial endotoxin reactions - such as instruments and horseshoe crabs for bacterial endotoxin reactions.

7. Measuring instruments to ensure the measurement of microbial colony number or inhibition diameter in various samples - such as airborne microbial samplers, airborne particle counters, microbial automatic measurement analyzers, etc.

Add one: microbial detection is of course indispensable to culture media, foreign and domestic brands include Beijing Luqiao, Qingdao Haibo, Guangdong Haibo, Merck, etc.

The establishment and procurement of food testing and analysis laboratories are based on national standards, and the corresponding laboratory analysis and testing instruments and equipment are configured in accordance with national standards. It is divided into dairy products, meat products, frozen vegetable products, fruits and dairy beverage products, mineral water products, canned products, and many other classified items. I know that Shijiazhuang sells equipment for the analysis laboratory of a food factory, and the address is in the middle of Jiahui Street, the county seat of Yuanshi.

Free home delivery.

Now the domestic logistics industry is very developed, and goods from all over the country can be reached. Xinjiang's products can be sold to Hainan, and Guangdong's products can be sold to the Northeast, hehe. Enterprises with import and export rights can also be international.

I am a chemical glass instrument franchise store in Shijiazhuang, honest and trustworthy, high reputation, free delivery to you.

In terms of microorganisms, sterilization equipment should include, ultraviolet lamp, pressure cooker. Also have a fridge. If you are too poor in terms of physics and chemistry, from what you said, you don't want to think about physics and chemistry, such as pesticide residues, additives, etc.

1. It is recommended to buy from a powerful dealer, not from different manufacturers, which is not easy to bargain.

2. Now that logistics is developed, it doesn't matter if it's farther away.

Recommend Xuzhou Huana Precision Instrument Company.

Can you be specific about the bai issue.

What products are tested, and what items are tested.

Generally, food inspection DAO needs to go back to 2 aspects.

1.Physical and chemical indicators, water content, sugar content, trace element content, etc. 2Microbial indicators, total number of colonies, whether it contains E. coli, etc.

Some food products are inspected more stringently. You need to name what foods need to be inspected.

The field of food testing is wider. You should be clear about the product and testing items, such as food safety: pesticide residues, return.

Veterinary drug residues, biotoxins, heavy gold.

A, food additives, etc.; Food nutrition: vitamins, amino acids, trace elements, proteins, sugars, etc.; Food product quality parameters: such as moisture, solids, specific substance content, etc.; Biological parameters:

Such as the total number of bacteria, pathogenic bacteria, molds, etc. These problems are determined, the equipment and investment can be basically determined, and the personnel needs should also consider the workload and the nature of the test.

It depends on what kind of food you are producing.

What are the main detection indicators?

Food safety detector, pesticide residue detector, food additive detector, veterinary drug residue detector, etc.

In terms of chromatography, there are mainly high-performance liquid chromatographs, ultra-high performance liquid chromatographs, gas chromatographs, and high-performance thin layer chromatographs. Optical:

Atomic absorption spectrophotometer, fluorescence, ultraviolet spectrophotometer, near-infrared, infrared, Raman spectrometer, polarimeter. Titration: potentiometric titrator, Karl Fischer titrator, permanent stop titrator.

Others: texture meter, rotational viscometer, melting point meter......

There are a lot of things to be done by food laboratory technicians, including food analysis, soft drink technology, food science high-tech, condiment technology, meat product technology, biotechnology foundation, and so on, and so on, in practice, the use of various experimental instruments, such as 722 spectrophotometer, suction filtration, vacuum distillation, and what is this method and that method, how can there be a test for this now? If you are a student majoring in food science and engineering, you don't need to take the exam, you can use it with your graduation certificate, and you are not afraid of the exam. If you are a layman, you want to take a food test...

Then there are too many things you have to learn, otherwise you may not be able to operate when you take up the post, such as giving you a bottle of wine, asking you if the lead content exceeds the standard, you have to have a complete set of plans, giving you a bottle of canned fruit, asking you what the Brix is, you also have to be able to measure, give you a bottle of mineral water, its microbial population exceeds the standard, meat products such as sausages, ham sausages, its nitrite exceeds the standard? So! Speaking of which, it depends on what kind of food laboratory technician you do!

Kjeldahl nitrogen meter, spectrophotometer, liquid chromatograph, fluorescence detector.

Physical and chemical parameters such as acidity, soluble sugar, starch, NaCl, etc., the method of optional titration is basically burette, etc., and no instrument is required.

Proteins, sulfites, etc. need distillation devices, and it is best to buy a Kjeldahl nitrogen meter for proteins.

Visible spectrophotometer for additives such as nitrate and nitrite.

Additives such as sorbic acid, benzoic acid, and sodium saccharin can generally be used with a liquid chromatograph UV detector.

Carbamate pesticides can be used with liquid chromatograph-fluorescence detectors.

Organochlorine pesticides can be treated with GC-ECD

Organophosphorus pesticides can be used with GC-FPD

If possible, most pesticides can be tested with liquid or temperament.

Microorganisms, mainly the environment, should reach a certain level of purification.

The commonly used equipment of food testing laboratories are: rotating food according to two parts: testing instruments and common equipment in food laboratories.

Rotating food testing instrument: It can quickly detect more than 200 kinds of food safety items, including qualitative and quantitative detection of non-edible chemical substances, abuse of food additives, pesticide residues, veterinary drug residues, heavy metals, diseased meat, nutritional enhancers, antibiotic residues, hormone residues, mycotoxin residues, chemical residues and other items.

Common equipment for food laboratories:

Electric drying oven: used for dry heating, sterilization and baking of straws, flat dishes and glassware.

Autoclave (also known as autoclave): Sterilization of items.

Balances: Analytical balances with an accuracy of 1/10,000 are generally required.

Microscope: An essential instrument for observing the morphology and motility of bacteria, microorganisms, and the structure of tiny objects.

Spectrophotometer: used in QS for enterprises that produce instant noodles, tea drinks, meat products, dairy products, cotton sugar.

Acidity meter: used in QS to produce canned fruits and vegetables, white sugar, drinking water enterprises.

Conductivity and turbidity meters: used in QS for enterprises producing drinking water.

Refractometer: used in QS for the production of canned fruits and vegetables, beverages.
