How to Choose Plastic Pasteur Pipettes
The relevant aspects of choosing Pasteur pipettes will be covered in this article. And tell you about some important aspects of choosing it.
About Pasteur Pipettes
Pasteur pipettes are too small to clean and are usually disposable. The disposable Pasteur pipette is micro and easy to use. It has a thin tip on one end and a bulb for sample extrusion on the other. A Pasteur pipette is a single-use plastic laboratory consumable that can be used for pipetting micro-samples. Next, we will introduce this product from the material.
Check Its Material
- Most of the common Pasteur pipettes on the market are made of LDPE, which is a relatively environmentally friendly material.
- This material is inert and does not easily react with other chemicals and will not contaminate your samples.
- Its molding technology is relatively stable, and its sealing performance is also excellent.
- It is soft and not easy to be damaged, and it will not be easily broken like glass.
- The material used in Pasteur pipettes is particularly light and easy to handle and store.
- It has low water absorption, does not require drying before processing, and is not prone to residual liquid samples.
- The chemical stability of LDPE is good. However, it cannot be used with strong acids and bases containing strong corrosiveness, so as to prevent it from dissolving into the solution and causing unnecessary trouble.
- And it also has good transparency to facilitate the observation of the sample condition.
- Its extensibility is very good, and there is no need to worry about extrusion deformation caused by excessive force during use.
Pasteur Pipette Volumes
- Pasteur pipettes provide a wide range of capacity options, ranging from 1mL, 2mL, 3mL, 5mL, to 10mL, to meet your experimental needs of different specifications.
- Small-volume Pasteur pipettes are small and suitable for experiments with precious samples. It has a slender tip and can extract tiny volumes of solution from small open containers.
- The large capacity can complete the operation of a large liquid transfer volume. They absorb and drip evenly without leaving sample residues that compromise the accuracy of experimental data.
- Pasteur pipettes on the market are also divided into sterilized and non-sterile versions, and the sterilized version is of course the safest product. Strictly sterilized pipettes are ideal for single use, ready to use without concern for contamination.
- You also need to pay attention to the scale line of its body. Choosing Pasteur pipettes with scale lines can make it easier to observe whether the liquid transfer process the amount you need. When you get the product, you should also observe whether its scale is clear and whether the interval between each section is even before putting it into use.
- Also, confirm its tightness before buying, check the production certificate of the store you buy from and review past customer feedback. After receiving the product you purchased, if the seal is not tight and contamination is found in the tube, please do not use it to avoid contamination of the sample.
