Types of Electric Pipettors

Understanding the types of electric pipettors is crucial when selecting the right one for your laboratory needs. Each type is designed for specific applications, offering unique benefits and features to streamline liquid handling tasks effectively.

Single-Channel Electric Pipettors

Single-channel electric pipettors are ideal for tasks that require precision with one sample at a time. They are versatile and suitable for general laboratory use, such as preparing standard solutions or transferring liquids for individual experiments. Their adjustable volume controls ensure high accuracy, making them reliable for tasks demanding precise measurements. Single-channel pipettors are widely used in smaller-scale laboratories or when fewer samples are involved.

Multi-Channel Electric Pipettors

Multi-channel electric pipettors are perfect for high-throughput environments. They enable simultaneous liquid handling across multiple samples, significantly increasing efficiency. These pipettors often come with 8 or 12 channels and are commonly used in applications like microplate-based assays. Multi-channel pipettors save time and reduce repetitive strain, making them indispensable for labs that process a high volume of samples daily.

Electronic Repeat Dispensers

Electronic repeat dispensers are designed for repetitive dispensing tasks. They can dispense the same liquid volume multiple times without requiring adjustments between dispensations. This makes them excellent for aliquoting solutions, reagent preparation, or repetitive dispensing in assays. Their programmable settings ensure uniformity and speed, reducing the chances of errors during repetitive tasks. These pipettors are particularly useful in labs handling repetitive, large-scale liquid transfers.

By understanding the functions and advantages of each type, you can choose an electric pipettor that best suits your laboratory’s requirements. Assessing the scale and complexity of your tasks will help identify the right tool.
