A BOD (Biochemical Oxygen Demand) incubator is a specialized laboratory equipment used to measure the oxygen demand of water samples, particularly in water purification and wastewater treatment studies. It provides a controlled environment, typically maintaining a temperature between 20–25°C and humidity above 90%, for microorganisms to decompose organic matter in the water sample. The amount of oxygen consumed during this decomposition process is then measured, providing a measure of the organic pollution level. 

Here’s a more detailed explanation:

How it works:The sample is placed in an air-tight bottle, which is then incubated in the BOD incubator under specific conditions for a set period (usually 5 days). Dissolved oxygen levels are measured before and after incubation, and the difference is used to calculate the BOD. 

Purpose:The primary function of a BOD incubator is to determine the Biochemical Oxygen Demand (BOD) of a water sample. 

Principle:The BOD test measures the amount of oxygen consumed by microorganisms while they decompose organic matter in a water sample. 

Controlled Environment:The incubator maintains specific temperature and humidity levels to facilitate the biological decomposition process. 

Applications:BOD incubators are used in various fields, including environmental engineering, wastewater treatment, and research to assess the quality of water and its potential for pollution.

What is a Laboratory Fume Hood?

A fume hood, also known as a fume cabinet, is a form of ventilation equipment used in laboratories to reduce exposure to poisonous or dangerous fumes, gases, dust, and vapours.In a laboratory for conducting chemical processes, a laboratory fume hood is the single most important element. A fume hood, also known as a lab hood or a chemical hood, shields workers from dangerous compounds they might inhale. The sash, a transparent movable screen on a fume hood, protects employees from splashes and spills that could happen inside the laboratory fume hood. The mainstay of laboratory exhaust systems, fume hoods are the most used method for local ventilation. Swastik is a leading laboratory fume hood manufacturer in India. We offer a wide variety of fume hoods for your labs, so whether you need one for research and development, quality control, education, or outside testing, we make all type of fume hoods available.

How does a Laboratory Fume Hood works?

When using a fume hood, air is drawn into the chamber with the help of a blower from away from the user. The facility exhaust system is used by the fume hood to cleanse the air before venting it outside. An alternative is to use a laboratory fume hood to filter the air, get rid of any harmful fumes, and then circulate the air inside the space. Most laboratory fume hoods have gauges or sirens that can alert the user to inadequate airflow and the possibility of being exposed to dangerous vapours.

A colony counter is a device that is frequently used to count bacterial or other microorganism colonies on a plate that contains a gelled growth medium.

Microbiologists have to tackle the daunting task of counting colonies, which can occasionally be undersized and obscured by the unique color of the cultural media or the enumeration process itself. Thus, everyday routines require a better and more effective method of optimizing procedures.

A colony forming unit or CFU is a precise measurement to determine how many bacterial or mycelial cells are present in a given sample. Thus, the colony counting approach monitors viable CFUs, which can still reproduce via a process like binary fission under carefully monitored settings.

Analytical and Precision Weighing Balance Functions

Most of us have never had the requirement to use more than the basic weighing function of a scale. However, many weighing balances are capable of much more advanced functions which can simplify a variety of complicated tasks. This handy article from Precisa presents an informative summary of some of the main Precision and Analytical Balance Functions, enabling you to get the most out of your weighing balance.

What is a Weighing Balance?

A weighing balance is an instrument that is used to determine the weight or mass of an object. It is available in a wide range of sizes with multiple weighing capacities and is an essential tool in laboratories, commercial kitchens and pharmacies.

What are the Main Weighing Balance Uses?

Balances are generally more sophisticated and precise than scales and are therefore commonly used by professionals for advanced scientific weighing in the following industries:

• Pharmaceutical
• Educational
• Food and beverage
• Chemical
• Industrial

Due to their high precision and advanced technology, precision and analytical balances are used in laboratories to efficiently perform specific tasks such as weighing test materials and sampling amounts, formulation, density determination, purity analysis, quality control testing and material and conformance testing. These analytical balance functions will be explained in detail in this article.  Balances with higher capacities are not only used in laboratories but can be used to test larger high-capacity weighing materials such as in construction sites

Adopting two microprocessors, one for controlling all functions of the balance and the other for total control of the furnace heat, BEL Engineering came to realize the ideal equipment for moisture determination of raw materials and finished products in the food, cosmetic, dairy, pharmaceutical, chemical, ceramics and construction material industries etc.

The philosophy to adopt two microprocessors in their Moisture Balances enabled BEL Engineering to introduce in the market a product with high performance at competitive cost.

Autotritration is involves automating the traditional titrator so that the titration, results calculation, sample preparation, and sample series analysis. By incorporating an automated system user increase reproducibility and repeatability while simultaneously reducing labor time per sample.

This also eliminates human errors and optimizes operational safety of lab personnel. Titration involves the slow addition of a solution of known concentration to a volume of another solution until a reaction has occurred. Its applications range from chemical analysis to environmental science.

Typically, titrations can be labor intensive depending on the application, however, autotitrators remove the time limiting steps usually associated with this technique. Considerations for your automatic tritrator should be based on sample load, sample type, and degree of throughput.
