Criteria for Selecting a Laboratory Homogenizer

Criteria for Selecting a

Laboratory Homogenizer

Homogenizers are valuable instruments in clinical and research settings. These high-speed mixers help to reduce various chemical or biological lab samples to tiny molecules of uniform size. They are designed to perform a wide variety of functions like blending, mixing, emulsifying, disrupting, dispersing or stirring.

Homogenization is an important sample preparation step preceding the accurate analysis of proteins, nucleic acids, pathogens and other samples. A clear understanding about the different homogenizing methods can help in selecting the

specifications include media viscosity, capacity, feed rate, motor speed, motor power, pressure range, and operating temperature.

Factors to Consider when Buying a Homogenizer Homogenizers often utilize pre-filled micro tubes with ceramic beads for disruption and mixing of samples.

This is supported by the oscillation or

reciprocal motion of the device. They are used to complete DNA, RNA or mRNA extractions combined with other procedures involving homogenization of samples without the degradation of nucleic acids. These devices come in various models such as handheld and benchtop and electrically powered to compressed air powered. As there many different types of devices, considering certain factors can help in choosing the right model for a specific application:

Motor Power Consider the drive motor power of the device which is expressed in terms of watts. A lightweight, handheld homogenizer will be ideal if you are processing small micro volume samples. On the other hand, if processing a thick, viscous material that is likely to put more strain on the motor, then a higher wattage unit will be required.

Speed Control and Range Speed control is a common feature on all types of these devices. Variable speed motor drives help make the homogenizing process faster, safer and more

thorough.

Benchmark Scientific’s Bead Blaster provides fast and efficient homogenization in seconds.

Cost Reliable suppliers provide top quality devices at competitive prices. Compare prices and specifications of various models to make the right choice.

Capacity Each lab equipment model will vary in terms of features and technical specifications. For instance, BeadBug Microtube, 230V from Benchmark Scientific has a capacity to mix, 1, 2 or 3 tubes simultaneously. A highly compact design, less than about 23 cm wide this model operates at a speed of 2800 to 4000rpm. On the other hand, this manufacturer’s BeadBlaster Microtube mixes up to 24 tubes simultaneously and delivers fast, efficient homogenization in about 35 seconds.

Processing Range It is essential to consider the processing range that includes the volume or sample size to be processed. For instance, multiple sample sizes ranging from micro liters to thousands of liters can be processed using the same device. Select the appropriate generator or tool suitable to match the specific volume range. Go for a model that delivers quick sample test results within minimum time.

Select a Reliable Supplier Before purchasing homogenizers, it is essential to choose a reliable and established laboratory equipment supplier. Selecting an online supplier will enable you to purchase quality products at competitive prices. Other benefits  Facility to compare different models and make the right choice  Competitive pricing and warranty  Quick delivery  Superior post-sales support
