Practical Tips for Choosing the Bottle-top Dispenser for Your Lab
Bottle-top dispensers are commonly used in various laboratories to measure liquid (typically between 1 and 60 ml) from a reagent bottle. Because they are used in so many different lab settings, there can be many factors to consider when choosing the right bottle-top dispenser for a particular set of needs.
A few questions to consider when shopping for the right bottle-top dispenser:
- Which chemicals will this bottle-top dispenser be used for – and will it be durable enough to tolerate them?
- Is this bottle-top dispenser easy to clean and calibrate?
- What is the nominal volume for this unit?
- Does this bottle-top dispenser have ergonomic controls to allow for ease of use?
A bottle-top dispenser is a long-term investment, so it is a good idea to consider all factors when choosing the unit to best suit your laboratory needs.
Commonly Asked Questions
- Do I need a bottle-top dispenser in my lab? - If you work in a laboratory environment where it is common to need to measure larger volumes that would be inconvenient using a pipette.
- How can bottle-top dispensers improve performance in the laboratory? - Properly calibrated bottle-top dispensers dispense reagents more quickly and with a higher degree of accuracy than when using a measuring cylinder or volumetric flask, so there is a smaller likelihood of error. And because they are designed to reduce spillage, they help to keep the workspace clean and free of contaminants.
