We do our best to give an accurate estimate of turnaround time when service requests are submitted. These estimates are not guarantees and occasionally change due to unforeseen circumstances (instrument maintenance/repairs, staff sick leave, etc.). Please let us know if you have a hard deadline on project completion when you submit your service request and we will take measures to ensure that we either meet that deadline or inform you ASAP if circumstances beyond our control will cause us to miss it. Thanks!
