Freeze Dryer Lyophilizer

Laboratory Freeze Dryer (Lyophilizer) For Long And Safe Storage of Samples

Summary: Freeze Dryer (Lyophilizer) is the best way to freeze dry samples of any biological kind for long term storage or staggered consumption purposes. They come with fully automatic temperature and vacuum controls.

Lyophilization is the process where test samples are subjected to freezing and vacuum in predefined temperature and environmental conditions. This is done in two stages. The first stage is sublimation or primary drying and second stage is desroption or secondary drying. With this process, the water content from the sample is removed completely, making the sample fit for long term storage.

This method is commonly used in production of freeze dried products including dairy, coffee, eggs, dried meat & fish and frozen fruits. It is also used in document recovery especially for moisture damaged papers like those that sank with the Titanic. Taxidermy is also a common area where freeze drying is used. Freeze Dryer (Lyophilizer) is the device specially developed for this purpose. It is made in different sizes and can be built in different sizes depending upon user requirements.

Common features of Freeze Dryer:

Most of the industry standard dryers are made to be as user friendly as possible. They are equipped with special validation ports and digital PID controllers. The devices are ready to use, and operators can plug them in any standardized power outlet. Commonly these devices are made in 2 to 50 liter ice capacity and temperature range can be defined at -40 degrees C or -110 degrees C. Precision vacuum control is used in these dryers and they are made using corrosion resistant material.

The cooling system in these devices is free of any CFC or HFC making it very environment friendly.  It comes with a factory fitted heating defrost system and a bottom mounted drainage system. Each device is generally put under 15- 20 days of Factory Acceptance Test in order to ensure effective usage and long life.

Common varieties of Dryers:

Depending upon the user requirement, Freeze Dryer (Lyophilizer) can be made in bench top designs or large size designs which can stand on a floor. Ice capacity of most common models is either 2, 3 or 5 KG. These devices can be customized for specific bio-products. The common choices include sensitivity to saline, enzymes, blood products, hormones and bodily fluids.

Common concerns of Dryer usage:

Many people who are untrained in using lab equipment tend to make costly mistakes. These dryers are special use equipment meant to be used by trained professionals. One important concern about the usage of these devices is knowledge of the melting point of the sample. Second common concern is the mistake of people thinking that colder is better. This can completely ruin some samples if they are not processed at specified temperatures. Another concern is that many times the operator may use wrong equipment unsuitable for the sample e.g. using a small machine for a large sample even though it may fit in the holder. Regular maintenance of the vacuum pump is another important consideration and so is the usage of inappropriate accessories.

Test Sieves


What is Test Sieve?

The test sieve is used for testing aggregate screen analysis, soil, rock, construction and filling materials, powder compounds, flour, seeds, powdered metals, foundry sands, coffee, minerals, chemical compounds, coal, artificial fertilizers and other particles or row materials in the laboratory, it is the most common laboratory research materials testing equipment. To be used for separation, fractionation or grain size determination.

The test sieve is employed in determining the size of solid particles. This technique is also called Granulometry. The laboratory sieve is used either in a column to determine a material’s particle size curve or singly for making a cut-off. In large diameters, the laboratory sieve can also be used to sieve powders. Test sieves are metal wire mesh pans made of stainless steel. Different industries use it for sieving, splitting and filtration. These are incredibly accurate for stress materials used in various types of particle analysis.

Laboratory Test Sieve Equipment Specify:

  • The dimensions of the frames.
  • The standardized openings.
  • Their respective tolerances.
  • The method of identification.

The Laboratory Test Sieve is made of stainless steel, has high efficiency and precision. Equipment specially developed for laboratory scale particle classification and analysis, always aiming to meet the most demanding requirements and standards in the market. Analyzed of this type are performed in laboratory procedures involving soil study and the manufacture of medicines, for example. Identifying particle size is essential for research results.

The process is carried out in a joint work of laboratory test sieve and sieve shaker. The sieves are deposited on the agitator, which will start the vibration, causing the material or particles to pass through the sieve size automatically.

What Are The Advantages of Test Sieves?

The laboratory test sieve is used for large variability programs because it reduces costs (less material needed and shortened test time) and lead time, without compromising the quality of the results.

Because it is not closed with a given sieve (the “standard closure sieve” of Bond’s test), the test can be used to simulate different sieves. This is particularly useful when large data sets where varying objectives of crushed product need to be investigated, and / or where final granularity has not yet been chosen.

Stability test Chamber

Everything You Need to Know About Stability Test Chamber

Lots of products are there in the market that needs to be stored, preserved and maintained in a safety chamber for good shelf life. In several industries, people need these types of chambers to keep their products in a particular atmosphere so that these sensitive products stay fresh and active for a longer period of time. Thus stability test chambers are quite popular in the manufacturing sectors across the world. In general, you can term a stability test chamber as a large scientific refrigerator that keeps important products intact and at per their actual condition maintaining the humidity and temperature of the product.

Keeping a controlled atmosphere is the key

Keeping pharmaceutical products in a controlled condition is very important. Stability test chambers mainly maintain the humidity of the pharmaceutical products in several companies. So who sets the measure of these chambers? Who controls and maintains the specification of these products? Well, the Food and Drug Administration or FDA, The World Health Organization or WHO or The International Conference on Harmonization or ICH are some of the organizations that fix and maintain the quality and specifications of these products. Specification for different products is different for obvious reasons. All the specifications are available online on the websites of these organizations.

Preserving the procedure is not easy!

If you think that preserving a piece of medicine is an easy task when you are highly mistaken! The piece of medicine or the pill can change its chemical composition with the change of humidity, temperature, and other factors. So before putting the pill in the chamber, it gets tested several times using different methods. Potency, Purity, Quality, and Identity of the pill should be tested before it is sent into the chamber. Microbiological tests are run on the pill to know whether there’s any change or degradation of the pill in this changed atmosphere. Finally, the perfect temperature is taken out and is kept the pill in that temperature.

Consider the change in temperature

Say a particular medicine is prepared in the UK and it is shipped to UAE as per the demand of the patients. Now when then medicine is being taken from the UK to UAE, the change in temperature is huge. It feels like going from the fridge and entering straight into the oven. So the change is temperature is drastic and here the importance of the stability test chamber can be seen. Sometimes the shipment doesn’t move directly from the UK to UAE! Say sometimes the package visits the USA in between. So the change in temperature is drastic and hence the stability chamber plays an important role during the shipment as well.

Consider the C’s:

When you are going to buy a stability chamber, you need to consider the most important three C’s. You need to consider Construction, Conditioning, and Control. CFC free double wall mounted chambers with enamel exteriors are one of the most popular and common products available across the world. The change in temperature will be huge. So the chamber must contain uniform temperature and humidity distribution system. A microprocessor unit is added to the chamber. This smart feature keeps the humidity and temperature as per the desired format. So these are some of the most essential features that a stability test chamber must possess.


Everything You Want to Know About Laminar Air Flow

What is laminar air flow?

Laminar air flow is basically a system that can circulate filtered air in panels which are parallel flowing. They are mainly used in hospital and other health care institutions. The people who work or lives in these places are exposed to air contamination and having a laminar airflow system, reduces the chances of acquiring it. The system also helps in preventing contamination due to bacteria and other contamination that might be caused due to chemical fumes.

How do they work?

The laminar air flow system mainly works with air that is moving with the same speed and direction with lesser cross-over of air streams. They help in getting a dust free and contamination free by sweeping the particles on a single direction, from the cleanest to the exit area. This design would ensure that the cleanest area is closest to the upstream of the face of filter.

Types of Laminar air flow

There are basically two types of hoods in the laminar air flow system, which are as follows,

Vertical- they are mainly featured with a filter system that is top mounted. The air in this system is pushed vertically and this helps the users to protect themselves from air contamination. The filtered air flows from the top of the device down to the working area. The user also needs to be in protected clothing so as to enhance his protection from all the harmful materials.


  • The floor space required to install this type of laminar system is quite less.
  • They are the best suited for compounding all sterile products.
  • As the filter is on top hence it is much easier to access.
  • The effect of turbulent is much from air striking larger objects is much less here.


  • As they are located overhead, cleaning them might be a bit difficult.
  • Items could not be placed at top as it might block the flow of air.
  • The turbulent effect of air striking is quite increased.

Horizontal- the air flow for this system occurs horizontally and goes to the users. This would keep the air contamination free and the users also do not need to wear any protective clothing.


  • The turbulent effect of air striking is much lesser.
  • Much easier to work and clean


  • Large objects might restrict the laminar flow of air
  • It might blow fumes or powder directly to the face of the operators.

Where are they used?

As mentioned earlier they are mostly used in hospitals and other medical institutions like pharmacy, operation room, pharmaceuticals, IVF, path labs etc.

Things to remember

  • While working with these devices make sure that all the written instructions are nearby.
  • Always check the hood before you start working with any of those dangerous chemicals.
  • The flow hood should always be placed in an area that has the minimal traffic.
  • It should always be checked that there are no obstructions in the exhaust system of the laminar air flow.
