Testimonials
We've been working with C&M Scientific ltd (now Labserve) for the maintenance, repair and calibration of our lab equipment for some time, and we couldn't be more pleased with their service. Fran and team consistently deliver outstanding support - from prompt and clear communication to the friendly and professional attitude of service engineers. Whilst on site engineers are respectful of our working environment, carrying out their work efficiently and with minimal disruption to our lab activities. Their expertise is evident, and they always leave us with full confidence that our equipment is in safe hands, and service reports are always delivered promptly after visits, providing us with clear and comprehensive information. I would highly recommend them to any lab users looking for reliable, high-quality service and support.
"We have used Northern Balance (now known as Labserve) for a number of years for our calibration needs and without question, we have always found them to be prompt and professional, a great service."
"Northern Balance (now Labserve) has been servicing and supplying balances to us for more than 20 years. In that time we have come to always expect a high level of service given by friendly and knowledgeable staff."
"Gateshead Foodbank was awarded a grant from National Highways to improve our warehouse facilities. Top of our shopping list was a set of roll-on scales that would greatly improve our food handling and safety processes. Northern Balance (now Labserve) went above and beyond not only in that they ensured we had the most appropriate equipment to do what we wanted but that they made a magnanimous gesture in providing the equipment for free. That allowed us to use the funds freed to purchase other much needed equipment. The Trustees of Gateshead Foodbank would like to express their profound thanks to Paul and his team at Northern Balance (now known as Labserve) and would highly recommend them to anyone."

The support from service engineer, Danny and the wider Northern Balance team made the process seamless and straightforward. Thereby greatly complementing our in-house team in the build up to this key GMP milestone."
"Whilst your engineer was here I asked him to do a bit of training of our lab staff and manufacturing staff over the correct way to use a balance, clean a balance, correct maintenance etc. This was very useful to both areas of our company and I am appreciative of him doing it. It is precisely this kind of helpfulness that your engineers have shown over the years that has maintained our business with Northern Balance (now known as Labserve) and that keeps us with Northern Balance."
