5 Types Of Laboratory Fume Hoods

Original Source: https://www.writerscafe.org/writing/Cleatech/2177724/


Laboratory Fume hoods are found in many different patterns and sizes-small benchtop units are available for space-challenged laboratories, and wider cabinet-type units are available for storage and space-consuming experiments. For example, specially built units are designed to protect users from radioisotopes, and units with a wash-down system of water spray nozzles scattered throughout the hood are required for perchloric acid work. Consider special user requirements, energy consumption, available space, and types of filters required when choosing a suitable hood for their lab. Fume hoods are a form of regulation in ecosystems exposed to dangerous chemicals and fumes. With the aim of protecting people from the negative effects of these fumes, fume hoods are used to get rid of the harmful aspects and enable employees to work safe. Working with substances that let off a harmful fume or odor, laboratories use fume hoods.

Laboratory staff can work straight under the fume hood with substances, or simply place the substance in the fume hood after the work has been done. Labor technicians will also ensure that the exhaust is working before work starts. Exhausting fumes is a hood's main job, so if that part of the ventilation system doesn't work, the hood won't work effectively. Check the baffles to ensure the exhaust is operating. These are movable partitions that create openings in the hood’s back. They maintain uniform airflow, which increases efficiency. Check for any impediments that may impede airflow. For other items such as paper towels, chemical wipes, and aluminum foil, be extra vigilant. These lightweight materials can be quickly drawn into the exhaust, thus impeding airflow. Use the sliding sash barrier when using a top fume hood on the bench. It's there for security and let them keep their face outside the worksite.

Here are the 5 Types of laboratory fume hoods

Ductless Smoking Hoods: A Ductless fume hood uses carbon filters in a laboratory to eliminate fumes and vapors. Carbon filtration, a cutting-edge technology used in a ductless fume hood, is an environmentally friendly option for both the consumer and the environment. The fume hood filters out the harmful fumes instead of funneling the fumes outside and then gets back the clean air back into the laboratory. Ductless fume hoods are also energy-efficient and cost-effective, and even provide electronic monitoring to consistently test filtration system performance.

Hoods for Chemical Fume: A Chemical fume hood is used in laboratories where workplace hazardous chemicals are being handled. This form of the hood is specially designed laboratory staff to work with these chemicals without revealing themselves to their associated harmful drawbacks. Featuring quality products and a design that goes beyond SEFA requirements, this device will ensure that staff can work safely with chemicals. The innovative fume hood design allows users to get a complete overview of their work and laboratory through a sash.

ADA Fume Hoods: An ADA Fume Hood is designed and built to be completely ADA-compliant in order to ensure a safe work environment. Every feature including lights, switches, epoxy-coated steel exterior, and digital airflow monitors is expertly engineered to meet the necessary safety requirements. ADA fume hoods can also be hand-operated and come with a standard stationary glass viewing panel with a safety glass counterbalanced sash.

Cabinets for Biosafety: In laboratories that deal with infections, have an enclosed, ventilated workspace, biosafety cabinets, and fume hoods are used. People can work with these units on materials contaminate with pathogens requiring levels of biosafety. This equipment ensures that the employees remain safe from dangerous chemicals or materials, and includes total recirculation and partial exhaust.

Hoods of polypropylene Fume: A Polypropylene Fume Hood is invented for laboratories that use products and materials rich in acids. These devices ventilate the indoor, air, avoid chemical damage, and are non-porous for healthy use for food testing. Reduced backflow of air also permits a much smooth production.

Above mentioned information regarding laboratory Fume Hood isvery useful for decreasing the pollution and many harmful chemicals. Besides this, the one who is a desire to be healthy during the laboratory experiments must use laboratory Fume Hoods in their laboratories.

Basic Data Types in Python | Python Web Development For Beginners

At the end of 2019, Python is one of the fastest-growing programming languages. More than 10% of developers have opted for Python development.

In the programming world, Data types play an important role. Each Variable is stored in different data types and responsible for various functions. Python had two different objects, and They are mutable and immutable objects.

Table of Contents  hide

I Mutable objects

II Immutable objects

III Built-in data types in Python

Mutable objects

The Size and declared value and its sequence of the object can able to be modified called mutable objects.

Mutable Data Types are list, dict, set, byte array

Immutable objects

The Size and declared value and its sequence of the object can able to be modified.

Immutable data types are int, float, complex, String, tuples, bytes, and frozen sets.

id() and type() is used to know the Identity and data type of the object

a**=25+**85j

type**(a)**

output**:<class’complex’>**

b**={1:10,2:“Pinky”****}**

id**(b)**

output**:**238989244168

Built-in data types in Python

a**=str(“Hello python world”)****#str**

b**=int(18)****#int**

c**=float(20482.5)****#float**

d**=complex(5+85j)****#complex**

e**=list((“python”,“fast”,“growing”,“in”,2018))****#list**

f**=tuple((“python”,“easy”,“learning”))****#tuple**

g**=range(10)****#range**

h**=dict(name=“Vidu”,age=36)****#dict**

i**=set((“python”,“fast”,“growing”,“in”,2018))****#set**

j**=frozenset((“python”,“fast”,“growing”,“in”,2018))****#frozenset**

k**=bool(18)****#bool**

l**=bytes(8)****#bytes**

m**=bytearray(8)****#bytearray**

n**=memoryview(bytes(18))****#memoryview**

Numbers (int,Float,Complex)

Numbers are stored in numeric Types. when a number is assigned to a variable, Python creates Number objects.

#signed interger

age**=**18

print**(age)**

Output**:**18

Python supports 3 types of numeric data.

int (signed integers like 20, 2, 225, etc.)

float (float is used to store floating-point numbers like 9.8, 3.1444, 89.52, etc.)

complex (complex numbers like 8.94j, 4.0 + 7.3j, etc.)

A complex number contains an ordered pair, i.e., a + ib where a and b denote the real and imaginary parts respectively).

String

The string can be represented as the sequence of characters in the quotation marks. In python, to define strings we can use single, double, or triple quotes.

# String Handling

‘Hello Python’

#single (') Quoted String

“Hello Python”

# Double (") Quoted String

“”“Hello Python”“”

‘’‘Hello Python’‘’

# triple (‘’') (“”") Quoted String

In python, string handling is a straightforward task, and python provides various built-in functions and operators for representing strings.

The operator “+” is used to concatenate strings and “*” is used to repeat the string.

“Hello”+“python”

output**:****‘Hello python’**

"python "*****2

'Output : Python python ’

Tips That You Know While Looking For A Good Fume Hood

Original Source: https://www.writerscafe.org/writing/Cleatech/2307520/

A lot of products are there that are more vital in comparison with the fume hood. Even, the most important equipment of a lab is the fume hood because it keeps the employees safe and protects them from all types of harmful chemicals. This not only keeps the working environment of the employee safe but also protects everything in the lab. If you are searching for a fume hood, here are some valuable tips that you need to consider.

What exactly fume hood is?

When the workers are dealing with the harmful chemicals or toxins, then these fume hoods are very effective to protect them and keep the lab safe from all fumes that could also be volatile. Two things are important that is done by fume hoods. First off, airflow is installed in the fume hood and make sure that fumes are taken outside the area and prevent people who are working inside the lab. Then filters and the exhaust system of the fume hood works to treat the air and disperse if it is required. These fume hoods are also necessary for the lab work, especially while working with the hazardous chemicals that could be poisonous and fatal is inhaled. 

What you ought to look for in a fume hood?

Firstly, these fume hoods need to have complied with the definite set of standards. Some organizations are there that are responsible for checking as well as certification of scientific equipment for lab use. To exemplify, lab equipment is certified by the Scientific Equipment and Furniture Association for usage within the lab however dangerous and harmful chemicals are used for experiment or research purposes. For instance, an airflow system needs to be present there in a fume hood and an alarm that sounds if there is any malfunctioning in the working of airflow. 

In addition to the warning alarms, you need to make sure that the fume hood has also extra-alarm settings for low airflow as well as filter alarms in case the hood is not working properly with the premium levels. To add on, if you are going to choose the ductless fume hood that includes the filters as well as blowers on top of the hood, then you have to ensure that the filters as well as blowers are effective to clean the air. You need to check out the fume hood’s sash because it pulls the air in the room. It provides the utmost protection to the fumes by preventing the workers from getting too closer.

Strong materials should be used in fume hoods such as stainless steel that is simple to clean and durable too. Make sure that the fume hood you get is perfect for the workplace and your employees as well. A good manufacturer fulfills all your needs and proffers safety to the employees too.

Ensure safety with Laboratory Fume Hoods

These fume hoods are helpful to reduce the exposure to the toxic and harmful fumes. Moreover, it is useful to provide protection against the lab’s environment and also safeguard the workers in the lab. It is a daunting task to find out the best fume hood from the huge number of options as available in the market. It is also tricky to pick up the one that suits best with the needs as well as space as available in the lab. 

Different types of fume hoods are also available in the market such as general-purpose hoods, bio-safety, PCR enclosures, extractor systems, ducted fume hoods, and vented enclosures. You can go for the one that fits perfectly with the applications and working needs. All these varieties have their advantages as well as disadvantages while considering the laboratory. 

How to pick up the best fume hood for the lab or workplace?

The first and foremost thing that you need to consider while choosing the best fume hood is that you need to establish whether you want protection for the staff or for the accessories as placed in the lab or for both. There are various choices as you can choose a horizontal or vertical clean bench if you intend to safeguard the products only. Other fume hood extractor or extract system and ducted or ductless chemical hood are suitable if you want to protect the staff from chemicals. If you tend to safeguard both employees as well as products, then you can give a try to the Class II biosafety cabinet and this is the best option.

Consider your needs first and then, narrow down the choices.
