Frequently Asked Questions

We calibrate most pipettes and analytical balances, and can service microscopes. In most cases, if you have multiple instruments that need servicing, we can coordinate service in one or more scheduled visits based on the scope of work.

No, we calibrate one channel and check all the other channels. We check all the other channels because sometimes the measurements are increasingly off as you checks towards the other side. We then re-adjust the calibration to find the best compromise where all the channels are within the range (manufacurer or ISO).

No. We only charge for the pipettes that pass calibration.

Some balances have an internal weight that is use during auto-cal or internal calibration. Usualy, we can change the menu to external calibration and use our set of calibrated weights to calibrate the balance.

First, we would have to examine the microscope to determine if we can repair it. We would have to look at it. Our skilled technicians can repair many models. However, often, the issue is caused by old grease that solidified and act similar to glue. Recently, we disassembled older Stereomasters and AlfaPhot models, cleaned up the old grease, re-lubricated the gears and re-assembled them. Now the clients are very happy with the performance of these older microscopes

Yes, many of our clients come to L.E.S. through referrals. We are grateful for that trust, and we would like to extend a simple thank you. If you refer a colleague who schedules service with us, you will receive 10% off your next invoice, up to $200.
