Classification of Pipettes
Pipettes are precise instruments for removing small amounts of liquid. Various pipettes are indispensable tools for the quantitative addition of various liquids in chemical technology, pharmaceutical research, biological analysis, environmental experiment, food detection, clinical diagnosis, biochemical determination, immune experiment, and micro-component analyses. According to the different working modes, the pipette can be divided into two types: mechanical pipettes and electronic pipettes.
Electronic pipettes
The electronic pipette is less used in all kinds of experimental analysis and measurement applications relatively. The electronic pipette is divided into four products according to the plug: a USA plug, a Cn plug, a Euro plug, and a UK plug. Although not strictly mechanical, electronic pipettes are worth mentioning as they are commonly used alongside mechanical pipettes. Electronic pipettes provide additional features such as digital volume display, programmable modes, and motorized pipetting operation, enhancing accuracy, precision, and ease of use.
Mechanical pipettes
Mechanical pipettes can be classified based on various factors such as their operating mechanism, volume range, and application. Here are the common classifications of mechanical pipettes:
The standard series pipette is half autoclave sterilized at 121℃. The standard series has been refined to include four products: Advanced Fully Autoclave Single-Channel Adjustable Pipettes, Standard Single Channel Fixed Pipettes, and Standard 8/12 Channels Adjustable Pipettes.
The advanced series pipette is also half autoclave sterilized at 121℃. Unlike the advanced series and standard series, the advanced plus is sterilized are fully autoclave at 121℃. So the plus series is more used for biological laboratory analysis. The standard and advanced plus series are also exactly the same subdivided into four products as the first two series.
1. Fixed Volume Pipettes: These pipettes are designed to deliver a single, fixed volume. They are commonly used when precise and repetitive dispensing of a specific volume is required. Fixed-volume pipettes are often available in a wide range of volume options.
2. Adjustable Volume Pipettes: Adjustable volume pipettes allow the user to set the desired volume within a given range. They typically have a volume adjustment mechanism such as a thumbwheel or dial that allows for easy selection of the desired volume. Adjustable volume pipettes are versatile and widely used in various laboratory applications.
3. Single-Channel Pipettes: Single-channel pipettes are designed to transfer liquid from a single source to a single destination. They are used when precise liquid handling in individual samples or wells is required. Single-channel pipettes are available in both fixed and adjustable volume configurations. Such as Advanced Fully Autoclave Single-Channel Fixed Pipettes, Advanced Half Autoclave Single Channel Fixed Pipettes, Standard Single Channel Adjustable Pipettes.
4. Multichannel Pipettes: Multichannel pipettes are equipped with multiple channels or nozzles, allowing for simultaneous liquid transfer to multiple wells or locations. The principle of the multichannel pipettes is the same as above. The multichannel pipettes are usually 8 or 12 channels, which is consistent with the 8X12 = 96-hole microporous plate. The use of multichannel pipettes can not only reduce the number of times of sampling operations but also improve the precision of sampling. They are commonly used in high-throughput applications where the transfer of liquid to multiple samples is required. Multichannel pipettes are available in fixed or adjustable volume options. Such as Advanced Half Autoclave 8/12 Channels Adjustable Pipettes, and Advanced Fully Autoclave 8/12 Channels Adjustable Pipettes.
