The Sorvall ST16R is a refrigerated centrifuge that offers you consistent power and performance that you expect from Thermo scientific. This simple to use instrument has safety features such as a push-button rotor locking system and a motorized lid. The automatic rotor detection sets the appropriate speed thanks to SMART Spin Technology. The upfront, easy to read digital control panel has a six-program memory back, storing runs that you use the most, and increasing lab productivity. From this digital command center users can choose their desired temperature for sensitive samples, from between -10°C to 40°C, their time parameters up to 9 hours and 99 minutes, and their desired speeds.
The Sorvall ST16R also features 9 acceleration and 10 deceleration profiles to best suit your needs. The maximum speed is 15,200 RPM and the ST16R has a maximum RCF of 25830 x g, holding up to 4 x 400 ml (1.6ml). When installing a refrigerated centrifuge finding a level, resonance-free surface is key for proper balance, away from direct sunlight as UV rays can degrade the plastics. This centrifuge should have 30 cm/ 12” of clearance on the sides to ensure proper airflow, with hazardous materials kept at least 12” from the sides for safe operation. Becoming familiar with the ST16R maintenance schedule will help to prolong the life of this centrifuge and includes daily cleaning of the chamber, rotor, and accessories.
Every piece of lab equipment that enters The Lab World Group receives a full preventative maintenance and quality control before being listed for sale. This ensures that all items ship within 1 to 3 days once your order is placed and that the lab equipment you receive is in pristine condition.
The first step is receiving the laboratory equipment into our facility. At that point regardless of the unit’s origin they are instantly decontaminated using both simple green and isopropyl alcohol. For the next step, the laboratory instruments are then entered into our inventory system where each piece of equipment receives its own tracking ID and history. The inventory management is a large part of our system ensuring each piece of equipment receives the appropriate care as well as for any consigned pieces our customers have perfect tracking of their assets.
The maintenance of the centrifuges, analyzers, incubators, etc are all unique to their functions in the lab. The preventive maintenance process for an analyzer is vastly different than an incubator or lab refrigerator. One of the major differences with The Lab World Group is we service all our own laboratory equipment and are experts in servicing everything from a vortexer to a Chromatography System.
The First step we undertake when testing your centrifuge is the same regardless of whether is refrigerated, a benchtop or ultra-centrifuge. We ensure the centrifuge is properly balanced on the floor. Next, we check the rotor for any chips or defects and weigh the buckets for appropriate weight. The key to properly running any centrifuge is to ensure the unit is always balanced both internal and external.
Next, we then check the unit for physical defects and worn parts such as missing drip pans, dings and dents, gas lid struts, LCD screens, centrifuge seals, rotor seals, lid locking mechanisms, etc. We then open the centrifuge and perform a full preventive maintenance on the unit. This includes lubricating and greasing any gears, parts, and mechanisms. The electronic boards are reviewed for defective or expiring electronic parts such as transistors or capacitors.
We then install the rotor and buckets and run the centrifuge at a low rpm to ensure it is balanced and running properly. Using a tachometer, we then calibrate the centrifuge at a low speed to ensure accuracy. After calibration of the centrifuge we then run it through continued testing. We test the unit for 20 minutes, 40 minutes and 60-minute cycles at various speeds. The various rcf and rpm tests allow us to test that low-speed calibration is holding at high centrifugation speeds.
Next the unit is given a secondary cleaning and decontamination. At that point we picture and video the unit to show you the exact centrifuge that you will be receiving including the specific rotor buckets and inserts. This ensures that once you order the centrifuge it can easily pass its additional outbound quality control and be shipped within 1 -3 days.
