| Dispenser Type: | |||
| Your choices are... | |||
| Bottle Top | Dispensing small volumes of sample from a bottle safely and reliably without contamination or waste can be difficult. Pouring introduces the possibility of contamination each time the bottle is opened and invariably leads to waste. Traditional bottle top dispensers are more convenient, safer and cut down on wasted sample. | ||
| Burette | A device for the volumetric transfer of reagents for a titration. It consists of a calibrated barrel, a delivery tip, and a valve (stopcock). | ||
| Other | Other unlisted or proprietary dispenser type. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||

| ||
| Capacity: | The volume of sample that can be dispensed. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Increments: | An increment refers to how the volume scale is divided up. | ||
| Search Logic: | All matching products will have a value less than or equal to the specified value. | ||
| |||
| Accuracy: | Accuracy is the degree to which the volume dispensed matches true or accepted values. | ||
| Search Logic: | All matching products will have a value less than or equal to the specified value. | ||
| |||
| Reproducibility CV: | CV=Coefficient of variation, it is a statistical measurement of the distribution of responses around the mean of those values. | ||
| Search Logic: | All matching products will have a value less than or equal to the specified value. | ||
| |||
| Rotation Angle: | A measure of how far the dispenser can turn. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
