Coronavirus Update   -   May 1, 2021

The spread of the COVID-19 infection has caused significant changes in businesses throughout the world. Perritt Laboratories recognizes that we provide essential testing and support services to many clients that supply important healthcare products. We want to assure our clients that we are currently, and we will continue to do all that we can to maintain our services during these difficult times. The following is an update on the status of Perritt Laboratories.

Child-Resistant Package Testing

Perritt Laboratories is pleased to announce that we have resumed child-resistant package testing.

COVID related closures forced testing to be suspended for many months. However, even though some restrictions and closures remain, Perritt Laboratories is once again able to perform package testing. We expect as more people are vaccinated, our ability to test will further increase.

Microbiological Testing Services

Perritt Laboratories continues to receive samples and to perform microbiological testing. We have taken the following steps to ensure the health and safety of our employees while continuing to provide our essential testing services:

  • Staffing and work schedules have been modified to reduce the number of people in the facility at any given time in order to allow for social distancing.
  • Cleaning and sanitation of the facility has increased.
  • Remote working for eligible employees.
  • Non-essential employees are on leave.
  • Access to our facility is limited to employees only.
  • On-site audits and client visits are suspended.
We are working with our suppliers to ensure that we maintain adequate amounts of materials for the continuation of testing.

Our microbiological testing continues as close to normal as could be expected given the current circumstances. We appreciate your patience if any of the testing and reporting is delayed due to the precautions that we have taken to ensure the health and safety of our employees.

We at Perritt Laboratories appreciate the overwhelming cooperation and support that we have received from our clients. We feel privileged to be able to provide our service to so many wonderful clients.
