Introduction<\/h5>
Pipetting, at first glance, would seem a fairly simple and easy task. Essentially described as glass or plastic tubes used to measure and transfer liquid substances of accurate volumes, pipettes are the ultimate laboratory tool. Yes, pipettes and micropipettes are easy to use–but, for scientists and professionals working in genetics, chemistry, microbiology, and medical research, transferring substances one at a time for experiments that would need a thousand or so samples can become an inexplicable nightmare.<\/p>
In the success of large-scale experiments, just as important as knowledgeable procedures, safety regulations, and accurate measurements is laboratory efficiency. Ordinary pipettes and automatic micropipettes already offer the former, but how about the latter? The solution for efficiency is as painless and straightforward as can be–multichannel pipettes.<\/p>
\u00a0<\/p>

Why Do You Need a Multichannel Pipette?<\/h5>
Multichannel pipettes are tools that allow the simultaneous aspiration of multiple pipette tips, effectively increasing laboratory output and reducing production time and costs. Different design variations of the multichannel pipette allow for the usual 8 to 12 to as much as premium 16, 48, and 64 pipetting channels that aspirate and dispense large volumes of liquid substances in welled trays at a time. However, increasing efficiency shouldn\u2019t come at a cost for measuring accuracy. The best multichannel pipettes are expected to deliver superior accuracy with high-volume pipetting, as well as maximum comfort to the user.<\/p>
\u00a0<\/p>

Selection Criteria for a Multichannel Pipette<\/h5>
With a large number of pipette brands on the market today, it can all get a little too confusing for the prospective pipette buyer. Premium laboratory equipment such as the multichannel pipette are expensive investments, and choosing the right variant is a crucial decision to be made. Nevertheless, this choice can be made easy once important benchmark criteria are kept in mind. What do you need to look for in a high-performance multi-channel pipette? Let’s look at our checklist.<\/p>
\u00a0<\/p>

Needs & Price<\/h5>
Do you need an electronic, 8-channel, 100 microliter multichannel pipette? Or a 12-channel pipette at 200 microliter settings? Establishing what is necessary for your experimental procedures is a must, before choosing among the other less essential features. But of course, as with any experimental pursuit, scientists can only dream of going beyond one\u2019s set budget. Therefore, the first thing on our list is financial considerations. This factor can quickly narrow down options, with different multichannel pipettes offering distinct features and properties at varying prices.<\/p>
\u00a0<\/p>

Comfortable Use<\/h5>
Conducting research can present very high demands for scientists, necessitating intensive manual labor across long periods of time. Spending hours in the lab with pipette in hand could prove an arduous task for any professional, and it is therefore important to consider that members of the laboratory staff are as comfortable as possible especially when using these complex instruments. Consequently, minimizing the risk of fatigue and wrist strain also minimizes the risk of error. The right multichannel pipette must have updated ergonomic designs for maximum productivity. Ideally, it may be equipped with a 360-degree rotation for convenience in adjusting to any position, and it must also be light enough to be comfortably held by the user for long periods.<\/p>
\u00a0<\/p>

Easily Cleaned & Autoclavable<\/h5>
Time is a limited resource in laboratory experiments, and none of it must be wasted on activities that are of lesser priority. Cleaning equipment, for example, is of utmost importance in the lab, but can potentially take too much time and workforce. Therefore, the right multichannel pipette must be easily cleaned and autoclavable to ensure lab safety and avoid contamination of substances without taking too much effort.<\/p>
\u00a0<\/p>

Universal Tip Fit<\/h5>
Given the wide array of pipette brands that exist in the market today, measurements might not be standardized for all variant products. That being the case, in buying new instruments for use in the laboratory, one must take into account the compatibility of equipment to the available resources. In the case of multichannel pipettes, the fit of the pipette tip can vary from brand to brand. Therefore, one must ensure that the multichannel pipette of choice has properly valued, widely available and easily acquired pipette tips.<\/p>
\u00a0<\/p>

Accuracy<\/h5>
Lastly, but surely not the least on our checklist, is the accuracy of measurement of the multichannel pipette. In using such a convenient, effortless, and efficient tool such as the multichannel pipette, it may be easy to disregard its number one purpose, which is to deliver substances in exact amounts. In transferring volumes one a time versus filling eight channels simultaneously, it isn\u2019t as easy for the scientist to do manual re-checks for precision. Therefore, relying on the accuracy of the instrument is of optimum priority.<\/p>
All modern laboratories should have multichannel pipettes in their arsenals. Now that we know what it takes to become a smart and responsible buyer of multichannel pipettes, here is a list of the best multichannel pipettes out there today.<\/p>
