The Final Word on the Sheldon Signature Benchtop Shaking Incubators 1570 Model 1570
For years, my lab has been in a constant state of evolution, each piece of equipment chosen to solve a specific problem or enhance a particular workflow. The need for a reliable, precise, and space-conscious benchtop shaking incubator arose from an increase in cell culture and aeration studies that demanded more than a simple stir plate could offer. After reviewing several options, the Sheldon Signature Benchtop Shaking Incubators 1570 Model 1570 stood out, promising a blend of quality and functionality at a competitive price point. My initial impression upon unboxing was one of solid engineering; the unit felt substantial, and the stainless steel interior hinted at the durability I’d come to expect from Sheldon equipment. While I briefly considered a larger, floor-standing model, the need to conserve valuable bench real estate made this compact unit the clear choice. My first reaction was a quiet satisfaction, a feeling that this piece of equipment might finally be the solution to my laboratory’s growing demands.
Real-World Testing: Putting Sheldon Signature Benchtop Shaking Incubators 1570 Model 1570 to the Test
First Use Experience
My initial tests were conducted in a standard university research laboratory environment, where temperature fluctuations are generally well-controlled but the occasional power flicker is a reality. I set up the unit on a dedicated bench space, ensuring it had adequate ventilation, as recommended. The initial setup was straightforward, plugging it in and running through the basic temperature and speed calibrations as outlined in the manual; the keypad interface was intuitive. I began with standard bacterial aeration protocols, running cultures at 37°C and 150 rpm for 48-hour periods.
The performance during these initial runs was remarkably smooth. The Sheldon Signature Benchtop Shaking Incubators 1570 Model 1570 maintained temperature with impressive accuracy, and the digital display for both temperature and speed was easy to read at a glance. I experienced no unexpected shutdowns or significant deviations from the set parameters. One minor quirk I noticed was the slight vibration transmitted to the benchtop at higher speeds, though this was easily mitigated by ensuring the adjustable leveling feet were properly secured.
Extended Use & Reliability
Over several months of continuous use, this shaking incubator has proven itself to be a workhorse. It has become an integral part of my daily workflow, accommodating various cell cultures, microbial growth studies, and small-scale metabolic experiments. I’ve subjected it to prolonged shaking periods, some exceeding 72 hours continuously, and it has performed flawlessly.
The stainless steel interior and shelves have held up remarkably well, showing no signs of corrosion or staining, even after accidental spills of common laboratory media. Cleaning is a simple affair; the smooth interior surfaces and removable platform allow for easy wiping down. The brushless DC motor has remained consistently quiet and efficient, with no discernible drop in performance. Compared to older, noisier units I’ve used in the past, this Sheldon model offers superior reliability and a much more user-friendly experience.
Breaking Down the Features of Sheldon Signature Benchtop Shaking Incubators 1570 Model 1570
Specifications
The Sheldon Signature Benchtop Shaking Incubators 1570 Model 1570 is a compact but capable unit, boasting a chamber volume of 113.3 liters (4.0 cu. ft.). Its interior dimensions measure 48.3cm x 49.5cm x 43.8cm (19″ x 19½” x 17¼”), providing ample space for a variety of labware. The exterior dimensions are 54cm x 59.7cm x 68.6cm (21¼” x 23½” x 27″), making it ideal for benchtop placement without dominating the workspace.
This model comes supplied with one universal shaking platform, measuring 43.8cm x 43.8cm (17¼” x 17¼”), which is quite generous for a benchtop unit. It features a microprocessor-controlled system for precise temperature adjustments. The temperature range for this non-refrigerated model is 5°C above ambient to 60°C (140°F), with an impressive temperature accuracy of ±0.5°C @ 37°C and a controller accuracy of 0.1°C.
The shaking mechanism is driven by a high-performance brushless DC motor, capable of delivering speeds from 40 to 400 rpm. Speeds are digitally controlled for maximum precision, with large, easy-to-read LED displays for both temperature and speed. A key feature is the user-adjustable stroke length, offering three options: 1.3cm (1/2″), 1.9cm (3/4″), and 2.5cm (1″), allowing for customization based on application needs.
For user convenience, there’s an internal light and an electrical outlet, both operable independently via exterior switches. Safety is paramount, with a door interlock switch that automatically stops rotation when the door is opened. The viewing door itself is a generous 48.9cm x 37.5cm (19¼” x 14¾”) and features 2.5cm (1″) hermetically-sealed, double-pane glass for excellent insulation. The unit operates on standard 120/230V, 50/60Hz electrical supply, with a power consumption of 1100W. It also includes four adjustable leveling feet for stability.
Performance & Functionality
The primary function of any shaking incubator is to provide controlled temperature and consistent agitation, and the Sheldon Signature Benchtop Shaking Incubators 1570 Model 1570 excels here. The temperature control is exceptionally precise. I’ve run long-term experiments where maintaining a stable 37°C was critical, and this unit never faltered, with uniformity staying within the specified ±0.5°C.
The shaking mechanism is robust and surprisingly quiet for its power. The 40 to 400 rpm speed range covers a wide spectrum of applications, from gentle aeration to vigorous mixing. The digital speed control is accurate, and the rotation remains smooth even when the platform is loaded with multiple flasks or plates. I particularly appreciate the user-adjustable stroke length feature; switching between orbit sizes allowed me to optimize conditions for different cell types and growth media, a flexibility I haven’t always found in comparable units. The door interlock is a thoughtful safety addition, preventing accidental spills or workspace disruptions.
Design & Ergonomics
From a design perspective, Sheldon has prioritized both functionality and durability. The stainless steel interior and shelves are not only easy to clean but also contribute to the unit’s overall sturdiness. The exterior has a clean, professional finish that fits well into a modern laboratory setting.
Ergonomically, the benchtop design is a significant advantage, saving precious lab space. The placement of the control panel and switches on the exterior is convenient, allowing for adjustments without needing to open the door and disturb the internal environment unnecessarily. The large viewing window is excellent for monitoring cultures without disrupting the internal conditions. The adjustable leveling feet are a simple but crucial detail that ensures stability on uneven surfaces, a common issue in older lab buildings.
Durability & Maintenance
Built with what appears to be high-quality materials, the Sheldon Signature Benchtop Shaking Incubators 1570 Model 1570 feels like a unit designed for longevity. The noncontact, low watt density nichrome heating element is a smart design choice, likely contributing to a longer service life by minimizing hot spots and thermal stress. The brushless DC motor is also known for its durability and low maintenance requirements.
Maintenance is straightforward. Regular cleaning of the interior and platform with a mild detergent and water is sufficient. The platform can be easily removed for thorough cleaning or sterilization. I haven’t encountered any specific maintenance challenges during my use, which is a testament to its robust construction and thoughtful design. The inclusion of a VWR Two-Year Limited Parts and Labor Warranty provides additional peace of mind for any unforeseen issues.
Accessories and Customization Options
The Sheldon Signature Benchtop Shaking Incubators 1570 Model 1570 comes standard with one universal shaking platform, which is designed to accommodate a variety of labware, though specific racks are sold separately. This modular approach allows users to purchase only what they need, whether it’s test tube racks or clamps for larger vessels. The platform itself is large enough to hold several standard Erlenmeyer flasks or multiple microplate carriers.
While the unit itself is highly functional, the ability to customize by purchasing additional or specialized shaking platforms and racks adds significant value. For applications requiring specific vessel configurations, this flexibility is key. The included platform is a good starting point, but planning for additional accessories early on can streamline specific experimental setups.
