Laboratory squeezer

Types of laboratory squeezers

The laboratory squeezer is a tool used in laboratories. It is used to squeeze fluids from flexible containers such as bottles and bags. The different types of laboratory squeezers are as follows:

• Laboratory Squeeze Bottle:

  These are bottles with a soft body that can be squeezed. Their nozzles are used to dispense liquids. The bottles are made from various materials. They include LDPE, HDPE, and PET. The materials used determine the type of liquid the bottle can store. For example, LDPE squeeze bottles are soft and flexible. They can be used to store thinner and more viscous liquids. HDPE bottles have more rigid bodies. They are used to store more viscous liquids. PET bottles are stiffer than squeeze bottles. They are suitable for the storage of non-vicious and corrosive liquids.

• Squeeze Valve:

  These laboratory instruments have a cylindrical body and a valve at the bottom. To open the valve, the user squeezes the body. The valve opens, and the content flows out when the pressure reaches a threshold. The flow stops when the pressure is released, and the valve closes. Some squeeze valves have a spring mechanism that closes the valve when pressure is released. Squeeze valves are used in the dispensing of slurries and powders.

• Roller Squeezer:

  The roller squeezer is also called the laboratory roller press. It has two rollers that can be rotated in opposite directions. When the rollers are pressed together, the distance between them reduces. The material being processed is squeezed as it passes through the rollers. Roller squeezers are used to separate solids from liquids. They are also used to extract juices from plant materials.

• Gasket Squeezer:

  The laboratory gasket squeezer is a combination of a squeeze bottle and a filter press. It has a squeeze bottle at the top and a stack of filter papers at the bottom. The squeeze bottle forces liquid through the filter papers when it is pressed. The papers then filter out the solid particles from the liquid. This squeezer is used in the laboratory to separate solids from liquids.

Design of laboratory squeezers

There are many laboratory squeezer designs to meet the needs of various applications. Each design improves the usability, efficiency, and accuracy of squeezing. They ensure that the results are consistent and reliable. Such designs provide the versatility and performance required for different laboratory tasks. They make them indispensable tools in research, quality control, and various scientific applications.

• Handheld squeezers

  Handheld laboratory squeezer devices are small and compact. They are easy to use with one hand. Their design usually includes a pair of handles that are pressed together to generate the squeezing force. Some might have a trigger mechanism for convenience. Handheld squeezers are great for small-scale operations. They can extract liquids from fruits, vegetables, or other soft materials.

• Bench-top squeezers

  Bench-top laboratory squeezer machines are bigger and heavier than handheld ones. They are designed to be used in conjunction with a laboratory bench. They often have more complex mechanisms. Bench-top squeezers are more appropriate for larger-scale operations. They can handle bigger samples or require more force to extract the liquid.

• Hydraulic press squeezers

  Mechanical press squeezers

  Both hydraulic press squeezers and mechanical press squeezers have a similar design. They consist of a robust frame that can withstand the applied pressure. The frame holds the squeezing plates. The plates may be moved by a hydraulic cylinder or a mechanical actuator. They come with a control system. It allows the user to adjust the amount of pressure applied during the squeezing process. These laboratory juice squeezers are suitable for extracting juice from fruits and vegetables.

• Roller squeezers

  Laboratory roller squeezers are designed with a system of rollers. These rollers can be turned by a motor or manually. The rollers press the material against a flat surface. It is an efficient way to extract juice, especially for large volumes of soft materials.

• Gear press squeezers

  Gear press squeezers are designed with gears of different sizes and teeth counts. The gears mesh together to crush and squeeze the material placed in the machine. Such designs are usually found in industrial-grade juice extractors.

Scenarios of laboratory squeezers

Laboratory squeezers have numerous applications in many industries. They include the following:

• Food Industry

  Laboratory squeezer is used to control the quantity of ingredients such as sauces, jams, and juices. They are also used to extract juice from fruits and vegetables.

• Pharmaceutical Industry

  In the pharmaceutical industry, laboratory squeezers are used to dispense ointments and creams. They help produce drugs that require the formulation of polymers and emulsification.

• Cosmetic Industry

  Cosmetic products such as lip balms, lip gloss, and creams are well-extruded using cosmetic squeezer bottles. It ensures the proper mixing of product components.

• Chemical Industry

  In chemical labs, laboratory squeezer bottles are used to dispense solvents and reagents. The chemical industry also uses squeezer bottles for extruding pesticides and fungicides.

• Biotechnology

  Laboratory squeezer is used in the extraction of plant and animal tissues. It plays a role in the extraction of DNA and RNA from biological samples.

• Material Science

  Laboratory squeezers are used in the synthesis of polymeric materials. They are also used to characterize the mechanical properties of elastomers.

• Environmental Science

  Laboratory squeezers are used to extract soil and water samples from the environment. They are also used to squeeze air from sample bags for gas chromatography analysis.

How to choose a laboratory squeezer

When choosing a laboratory squeezer, think about the needs of the lab. First, identify the materials that need to be squeezed and their properties. A wide range of options is available, from soft to hard.

Consider the design of the laboratory squeezer and the space available. In smaller labs, manual squeezer machines or handheld models might be more suitable. Bigger labs may require floor-standing or bench-top models. Also, consider how much material needs to be processed within a given period. The output capacity and squeezing speed of the equipment should be sufficient for the laboratory's needs.

It is essential to ensure that the laboratory squeezer's construction materials and design comply with the laboratory's cleanliness and safety standards. The device should be easy to clean and maintain to ensure long-term performance and hygiene. Think about the budget as well. Find a balance between the laboratory's needs and the financial constraints.
