Lab pipettes – Buying guide & Comparison
If you are short on time, and you just want to find the best pipettes, this concise paragraph should help you get just the model you need. According to our research, the Glove Scientific 139050 LDPE 100 Pack is worth considering as it can help you with performing multiple tasks both in the lab and at home. Every pipette comes with a capacity of 23 milliliters and has a length of 300mm. What this means is that you won’t have to make an effort to grab the liquid as the size of the product will enable you to do just that without having to come into contact with the substance. Moreover, these pipettes are made of low-density polyethylene, which renders them non-slippery and capable of being frozen in liquid nitrogen. In case the Glove Scientific 139050 LDPE 100 Pack is no longer available, we suggest opting for the next best choice, the SEOH 41121513 Glass Droppers.
What is the best brand of pipettes? Which ones fit the application you have in mind? If you’re having a bit of trouble providing an answer for these two questions but plan to get some of the best laboratory pipettes available for sale out there, we’re here to help you. In order to save you some time that you’d have to spend reading countless articles about selecting the right products, we suggest you check out our simple buying guide. It can assist you when it comes to making an informed decision.
This is one of the first factors you ought to keep an eye on. Just how much liquid can you transfer with the help of the pipette you might want to purchase? Bear in mind that sometimes, bigger is better, and we’re not here to disagree. If you have no idea whether you might require adding more and more liquid to your sample, perhaps you’d benefit from using a sizeable pipette. If, on the other hand, your working protocol requires you to add just one milliliter of liquid per sample, you already know the volume you’re looking for.
Not all of these products are designed the same, and the same rule applies in the case of the applications they might be a great fit for. If the area you work in needs somewhat accurate measurements, what you may be in need of is a graduated pipette. If you can use just your eyes to tell how much liquid you’ve poured into a Petri dish, for example, then you may not need the services offered by a graduated model. There aren’t any significant differences in regard to the price of graduated and non-graduated items, so you needn’t worry about spending too much money on one or the other.
For some, the best ergonomic pipettes are made of glass, whereas others simply prefer the convenience offered by plastic alternatives. Glass has some net advantages over plastic, which are mostly related to the fact that the items constructed of this material can typically be reused. Most glass pipettes can be washed and even sterilized, depending on the durability of the parts in the product. From what we have gathered on the topic, glass models are usually a little more expensive compared to their plastic counterparts, but it really boils down to whether you’re comfortable with using a rubber bulb or one that’s integrated into the body of the item and has been made of a rather flexible type of plastic. The vast majority of these last options cannot be sterilized using a substance or heat, which is why they are traditionally made to be disposed of right after having been used.
Price, recommendations, and manufacturing brands
In most cases, you are likely to see that even the best manual pipettes don’t cost a lot of money. Depending on their capacity, packs of 100 pieces can be found for as little as five dollars or even less. The cost does add up when you’re working in a busy lab where hundreds of samples are processed on a daily basis. That’s why it might pay off to continue your research and go through the best pipette reviews as there are many professionals who might report an issue if they’ve come across any. As for the brand that has manufactured the pipette, we recommend buying a model made by companies that are renowned for the quality of their products. Karter Scientific and SEOH are just two examples.
