What is the flow range?Depending on the pump you select, our pumps offer a range of flow rates from 0.2 µl/min to 60,000 ml/hour.
Is the flow reversible?
Yes. The desired flow could achieved either by clock-wise or anticlock-wise rotation.
Could you please provide me information about the precision of dosing of a Lambda peristaltic pump? Accuracy of the pumps is about ±1% and the reproducibility is ±0.2% (electronics). Speed of rotation of the pump motor is regulated with a precision of quartz watch, which in-turn assures a high precision of the flow rate.
How would I calibrate the flow rate in peristaltic pumps?The calibration of the pump flow rate with speed can be done to know the amount of the liquid pumped. It could be done in two ways: volumetric calibration of the peristaltic pump flow and pump flow calibration by weight. A short video of peristaltic pump flow calibration can be found at https://www.lambda-instruments.com/peristaltic-pumps/#video
Can I get multi-channel pumps?We do not manufacture multi-channel pumps. Because with the multi-channel pumps it is not possible to achieve the precise and reproducible flow rates with only one pump motor. For the high precision of flow rate, it is not advisable to use the multi-channel pumps.If one channel gets blocked then your whole project will get spoiled totally. Instead, we recommend having individual pumps.
Why do I need to use LAMBDA individual pumps over multi-channel pump?It has more advantages over the multi-channel pumps. The most important thing to take into account is the precise, reproducible and steady flow rate.If one channel gets blocked then your whole project will get spoiled totally.The bench space required for the needed channel equivalent to individual LAMBDA Pumps is same as that of a single multi-channel pump, because of the compact structure of the LAMBDA Pumps. The individual pumps can be used in other projects too.
Do you have pumps on stock?Yes, we have the pumps in stock. We maintain a large stock of instruments, in order to be able to quickly set them up in the desired configuration and to dispatch them in shortest possible time, within few days!
