Let’s Dive into Labconco CentriVap Benchtop Centrifugal Concentrators and Systems, Labconco 7811020 Cold Traps Cold Trap
The Labconco CentriVap Benchtop Centrifugal Concentrators and Systems, Labconco 7811020 Cold Traps Cold Trap represents a crucial piece of equipment for any laboratory dealing with sample concentration. It’s designed to efficiently and effectively evaporate solvents from multiple small samples simultaneously. This system is a game-changer for biological, biochemical, pharmaceutical, and analytical chemistry applications, significantly speeding up sample processing.
My work in a high-throughput screening lab required us to concentrate hundreds of samples daily, a task that was previously a bottleneck. We needed a reliable system that could handle various solvents, minimize sample loss, and maintain consistent performance under heavy use. The Labconco CentriVap system seemed to tick all the boxes.
The unit arrived well-packaged and protected. The initial impression was one of robust build quality; the epoxy-coated aluminum chamber felt solid, and the controls were intuitive. Compared to our older, less sophisticated vacuum concentrator, the Labconco CentriVap looked like a significant upgrade.
We were previously considering a Savant SpeedVac system and a Genevac HT-4X. The Labconco stood out due to its integrated cold trap and the promise of acid-resistant components in the acid system, which was crucial for some of our workflows. My first impression was optimistic. I was excited to see how it would streamline our sample preparation process, but a little apprehensive about the price.
Real-World Testing: Putting Labconco CentriVap Benchtop Centrifugal Concentrators and Systems, Labconco 7811020 Cold Traps Cold Trap to the Test
First Use Experience
The initial testing took place in our analytical chemistry lab, concentrating samples of various organic solvents and aqueous solutions. We subjected the Labconco CentriVap system to a series of runs, monitoring the time required for complete evaporation and checking for any signs of sample degradation or loss. The system performed admirably, even with volatile solvents.
The cold trap effectively captured the evaporated solvents, preventing them from contaminating the vacuum pump. The microprocessor-controlled operation eliminated bumping and foaming, resulting in consistent and reliable concentration. It was easy to set up and use straight out of the box. The LCD display clearly showed the program number, temperature, and runtime. The only surprise was how quiet the system ran compared to our old concentrator.
Extended Use & Reliability
After six months of nearly daily use, the Labconco CentriVap has proven to be a workhorse in our lab. There are no noticeable signs of wear and tear. The epoxy coating on the aluminum chamber is holding up well, even with occasional spills.
Cleaning and maintenance are straightforward. The stainless steel collector in the cold trap is easily accessible and drains quickly. Compared to our previous concentrator, which required frequent repairs and recalibration, the Labconco CentriVap has been remarkably reliable. It has significantly outperformed our expectations in terms of throughput and ease of use.
Breaking Down the Features of Labconco CentriVap Benchtop Centrifugal Concentrators and Systems, Labconco 7811020 Cold Traps Cold Trap
Specifications
The Labconco CentriVap Benchtop Centrifugal Concentrator boasts a 30.5cm (12″) diameter epoxy-coated aluminum chamber. This spacious chamber accommodates a wide array of high-capacity rotors. Its brushless motor reaches a maximum speed of 1725 rpm.
The system features a microprocessor that expertly manages centrifugal motion, eliminating bumping and foaming during vacuum evaporation. A large automatic vacuum release valve safeguards samples, rapidly releasing the vacuum before the rotor halts. The built-in vacuum delay prevents bumping during startup, allowing the rotor to achieve set speed before applying vacuum. It has the ability to store up to nine user-set programs that define temperature, heat time, and run time.
The Labconco 7811020 Cold Traps Cold Trap utilizes a CFC-free refrigeration system with a 1/4 hp compressor. This quickly lowers the temperature to –55°C (–67°F) in under 20 minutes. The cold trap features an acrylic lid with two quick-disconnect fittings for 1.3cm (1/2″) I.D. hose, an LED temperature graph display, and a 4L stainless steel collector with a corrosion-resistant nylon valve. The unit reviewed is specified as 115V, 60Hz, 5.4A.
Why These Specs Matter: The large chamber and high rotor speed allow for processing a greater number of samples in a single run, increasing efficiency. The microprocessor control and vacuum release valve minimize sample loss and ensure consistent results. The cold trap’s low temperature effectively captures a wide range of solvents, protecting the vacuum pump and the environment.
