Haematocrit centrifuges: a buying guide to help choose a haematocrit centrifuge for your laboratory

In this month’s blog, we take a closer look at haematocrit centrifuges and what factors you need to consider when buying one. Furthermore, we will look at how Henderson Biomedical can help with regards to you haematocrit centrifuge needs. let’s take a closer look:

What is a haematocrit centrifuge?

A haematocrit centrifuge is a laboratory instrument used to separate blood components based on their density, particularly to determine the volume percentage of red blood cells in whole blood. This percentage is known as the haematocrit.

Here is how it works:

• Blood sample preparation: A small amount of blood is usually collected into a capillary tube or microhaematocrit tube.
• Centrifugation: The tube is then placed in the haematocrit centrifuge, which spins rapidly. Centrifugation uses centrifugal force to separate the blood into its components based on their density.
• Component separation: The different components of blood have different densities. Red blood cells, being denser, migrate to the bottom of the tube during centrifugation, forming a distinct layer.
• Measurement: After centrifugation, the length of the red blood cell layer is measured and compared to the total length of the blood column in the tube. The ratio of the length of the red blood cell layer to the total length of the blood column gives the hematocrit value.

The hematocrit value is an important parameter in assessing various medical conditions, such as anemia or polycythemia. It provides information about the proportion of red blood cells in the blood, which is crucial for understanding the blood’s oxygen-carrying capacity.

What are the different haematocrit centrifuge options?

Several laboratory equipment manufacturers produce hematocrit centrifuges. Here are some well-known makes and models of haematocrit centrifuges:

• Hettich HAEMATOKRIT 200
• Sigma 1-14
• MSE Micro Centaur
• Hermle Z 207 H
• Sorvall Legend Micro 17

Before purchasing a haematocrit centrifuge, it’s essential to consider factors such as speed, capacity, features and any specific requirements for your laboratory applications. Additionally, check for customer reviews, warranty, and after-sales support to ensure the quality and reliability of the equipment.

Factors to consider when buying a haematocrit centrifuge

When buying a hematocrit centrifuge, it’s important to consider several factors to ensure that the chosen model meets the specific needs of your laboratory. Here are some key factors to consider:

• Capacity: Determine the number of samples you need to process simultaneously. Centrifuges come in various capacities, so choose one that can accommodate your typical workload.
• Speed (RPM) and Relative Centrifugal Force (RCF): Consider the types and sizes of tubes or containers that the centrifuge can accommodate. Ensure that it is compatible with the sample containers commonly used in your laboratory.
• Safety features: Look for safety features such as lid interlocks, imbalance detection, and over-speed protection to ensure the well-being of users and prevent damage to the centrifuge.
• Ease of cleaning and maintenance: Check how easy it is to clean and maintain the centrifuge. Look for models with easily accessible parts for routine cleaning and maintenance tasks.
• Footprint and portability: Consider the available space in your laboratory and the portability of the centrifuge. Some labs may benefit from smaller, more portable models.
• Brand reputation and after sales technical support: Choose a centrifuge from a reputable manufacturer with a history of producing reliable laboratory equipment. Check customer reviews and the availability of after-sales support, including warranties and service options.
• Cost and budget: Consider your budget constraints. While it’s important to invest in quality equipment, make sure the chosen centrifuge meets your needs without exceeding your budget.
• Regulatory compliance: Ensure that the centrifuge complies with any relevant safety and regulatory standards in your region, especially if you work in a clinical or diagnostic laboratory.

By carefully considering these factors, you can select a hematocrit centrifuge that aligns with your laboratory’s specific requirements and applications.
