Design and Build
The Slendor SH-2 features a square, white design with a heating plate surface measuring 4.7 by 4.7 inches. The primary construction material is noted as polytetrafluoroethylene (PTFE, commonly known as Teflon), which is selected for its resistance to high temperatures, abrasion, and chemical corrosion. This material choice is a key selling point for laboratory environments where exposure to various reagents is common, as it helps ensure the platform’s durability and ease of cleaning. The overall dimensions are compact, which should allow it to fit into various lab spaces without occupying excessive bench area.
The unit’s controls are analog, with a speed-regulating device located at the bottom. This knob is rotated clockwise to increase stirring speed and counterclockwise to decrease it. The design philosophy here is one of simplicity, forgoing digital displays for straightforward manual adjustment. The product includes a support stand, presumably for holding the included thermometer or other apparatus above the stirring vessel. The build is described as having undergone testing and inspection, with the manufacturer emphasizing stable long-term operation as a quality assurance goal.
Performance and Features
Stirring Capability
The core function of the Slendor SH-2 is magnetic stirring, with a maximum rotational speed of 2000 RPM. The adjustable speed control allows users to match the mixing intensity to their specific experimental needs, from gentle agitation to more vigorous stirring. The inclusion of a one-inch Teflon-coated magnetic stir bar is standard and necessary for operation. The manufacturer provides guidelines for continuous operation, suggesting a limit of 4 hours at high-speed settings and up to 8 hours at medium speeds, which is an important consideration for prolonged experiments.
Heating Performance
A significant feature of this unit is its ability to heat and stir simultaneously. With a heating power of 180W, the plate can reach a maximum temperature of 520°F (270°C). This dual functionality can save considerable time in lab procedures that require temperature-controlled mixing. The included thermometer is intended for real-time temperature monitoring during use, though it is an analog tool separate from the unit itself, as the SH-2 does not have a built-in digital temperature display or control.
Material and Durability
The use of advanced, resistant materials is highlighted as a key feature. The PTFE surface is designed to withstand the high temperatures it generates, along with abrasion and chemical corrosion. This makes the stirrer suitable for use with a variety of substances without degrading the work surface. The manufacturer states each unit is tested and inspected to guarantee quality, aiming for stable performance over extended periods, which is crucial for reliable experimental outcomes.
Setup, Support and Ownership
Setup for the Slendor SH-2 appears straightforward, involving placing the unit on a stable surface, inserting the magnetic stir bar into the vessel, and using the bottom knob to adjust speed. The included accessories—stir bar, thermometer, and stand—mean no immediate additional purchases are necessary for basic operation. The manufacturer notes that customer service is available for any questions regarding the lab hot plate, though specific details about warranty length or support channels are not listed in the provided data.

The manufacturer’s description indicates a stirring capacity, but the exact maximum volume for the SH-2 model is not explicitly listed in the provided data. It is advisable to consult the product manual or manufacturer specifications for detailed capacity guidelines related to vessel size and liquid viscosity.
Does the Slendor SH-2 have overheat protection?
The provided product data does not specify the presence or absence of overheat protection or other safety cut-off features. Safety features are not listed among the key specifications or manufacturer features. Users should operate the device according to the provided guidelines, such as the recommended continuous operation times.
Can I use my own magnetic stir bars with this unit?
Yes, magnetic stirrers are typically compatible with various stir bars, provided they are of an appropriate size and material for the magnet strength and the chemical resistance required. The unit includes a one-inch Teflon-coated bar, but other bars should function as long as they can be effectively coupled by the rotating magnet within the plate.
Is the surface easy to clean after a chemical spill?
According to the manufacturer, the plate is made from polytetrafluoroethylene (PTFE/Teflon), which is noted for its resistance to chemical corrosion. This property should make it relatively easy to clean after most common lab spills, as many chemicals will not adhere to or degrade the non-stick PTFE surface. Standard laboratory cleaning protocols for such materials should be followed.
