Various Cleaning Practices For Maintenance Lab Equipment

Keeping the lab equipment clean and sanitized is an essential task that must be performed in order to keep the operations of research lab smooth and efficient. For the safety of the environment and protecting the lab equipment from getting contaminated after the usage in lab experiments.

Variety of tools and techniques are used to clean these equipments. And the proper sanitization ought to be done in a careful manner lest the harsh chemicals still contained in the lab supply could harm the users. The lab equipments are put in use for different chemicals, flammable materials, acids, bases, reagents, etc. so caring for them is a an important act. 
The most commonly used materials for cleaning up are paper towels, and gloves along with distilled water. To ensure the precise results, the lab apparatus should be cleaned and made free from grease and chemicals that are left residue on the glassware. Use distilled water to see if the water wets the surface smoothly.

If there are dry spots being left, then those areas need to be cleaned so that the next time they are being used in experiments, they do not contaminate the materials used for the reaction. And if there is any glass apparatus that has been cracked or chipped, then dispose them immediately as they could cause injury or failure in the experiments.

Always wash the glass apparatus thoroughly after use. Otherwise the residues of the experiment can be difficult to clean at the later stage. The new glassware is slightly on the basic side so it should be washed with water and put in a solution containing 1% acid such as hydrochloric acid or nitric oxide and rinse it later with water.

But it is precautionary to never soak the labware for very long or else the solution can ruin the glass. And to clean the residue that is attached on the labware, always use brush with soft bristles with a wooden or plastic handle so that glass is prevented from abrasion by extreme friction. Make sure to buy quality lab equipment from a reliable supplier in NYC region.

Medical Laboratory Equipments And Its Safe Handling

Several tests are conducted in a medical laboratory for the information on the health of a patient. For the diagnosis and treatment of medical conditions different types of lab equipments are used. Scientists and physicians use different lab equipment to conduct experiments, collect data, testing of different parameters and health factors and carrying out serious measurements. This information helps the medical laboratory scientist to examine the medical state of a patient and thus give proper prescription.
The laboratory equipments are manufactured under strict scientific control and thus maintain highest level of safety standards. Medical laboratory procedures depend on various types of lab wares for checking and measuring critical fluid parameters.

Important Laboratory Equipment

The various tools and articles used in medical laboratory needs to be sterilized and disinfected. The most important activity to be followed is to keep each and every material used in lab perfectly sterilized. Normally chemicals are used for this purpose, and they become important ingredients of the laboratory.

The following equipments are used for the purpose of sterilization of the equipments:

Hot Air Oven: Hot air oven is electrically operated and thermostatically controlled device. The structure of oven is two – walled steel chamber equipment. The articles to be sterilized are placed inside it and are sterilized through hot air convection method.

Autoclave: An autoclave is made of metal jackets to maintain high pressures. Water inside it is boiled to produce high steam pressure. The tools to be sterilized are placed inside it and are disinfected through the generation of pressurized hot steam flow. 

Water bath: In medical laboratories water bath is used to heat things uniformly from all sides at a set temperature up to the boiling point of water.

Other common laboratory equipment used for various applications includes the following devices:

Weighing scales
: Weighing scales are used to find out the weight of different medical quantities that are large. On the other hand for the measurement of smaller quantities analytical balance is used.

Compound Microscope: No laboratory is complete without this sophisticated device. Compound microscope is to magnify the microscopic constituents of a human body specimen like blood, tissue etc which enables exact verification of its biological conditions.

Centrifuge: Centrifuge is used to determine the volume of packed cells of RBCs. A centrifuge machine is used to quickly separate and deposit the molecular elements like cell. The process is called centrifugation. Its speed is represented in rotations per minute. Here, capillaries filled with blood samples are rotated at high speeds and the amount of RBC is calculated.

Precision Incubators: These incubators are suitable for different applications like in clinical, industry, research, and microbiology. The general-purpose incubators are the ideal choice for hematological, biochemical, pharmaceutical, microbiological studies.

Caliper: It is a medical device used to measure thickness of an object in millimeters. The thickness of subcutaneous fat tissue is measured by this instrument.

Hemacytometer: It is used for the counting of blood cells or particles in a sample. Glass Hemacytometer is a thick microscope slide to determine the number of particles in the given volume of liquid.


To work safely with hazardous chemicals you need to properly use laboratory equipments which can be done by maintenance and regular inspection of laboratory equipment. Many of the accidents that occur in the laboratory are the cause of improper use or maintenance of laboratory equipment. It is the duty of laboratory personnel to check if the equipments are maintained well, properly and safely used.

The following precautions should be kept in mind and the necessary adjustments should be made before working in the laboratory:

. Insulate all electrical equipment properly:  Every month inspect all the electrical cords visually for any damage. Rubber covered cords can be worn out by organic solvents and by ozone.

. Replace all damaged cords before any further use of the equipment is permitted: The replacement should be carried on by qualified personnel.

. Ensure the complete electrical isolation of electrical equipment and power supplies: All the power supplies should be enclosed in a manner that makes accidental contact with power circuits impossible.

. Minimize the condensation: If the electrical equipment is placed in a cold room, you will have to minimize the condensation that may enter the equipment. Cold rooms are risky as the atmosphere is frequently at a high relative humidity, and the possibility for water condensation is significant.

. Mount the equipment on a wall or vertical panel: This precaution will reduce the condensation problem.

. Avoid using variable auto transformers: Do not use variable autotransformers to control the speed of an induction motor as this will cause the motor to overheat and perhaps start a fire.
If the equipments are handled with care, they will work for long duration and without causing any harm. New innovations are rising day by day in the field of medical technology in NYC. Modern medical experts are designing different types of lab equipment that will provide remarkable medical assistance in the near future.
