S212 Series Laboratory Double-Layer Glass Reactor Product Overview
Core Abstract The S212 Series Laboratory Double-Layer Glass Reactor is a precision experimental device that performs stirring reactions under set constant temperature conditions and can control the reflux and distillation of reaction solutions. This machine is best suited for R&D and small-scale trials in industries such as fine chemicals, biopharmaceuticals, and new material synthesis. Its core advantages include the use of premium borosilicate glass material ensuring excellent corrosion resistance and thermal stability, diverse reaction capacities from 1L to 5L, and an advanced PTFE bearing seal system with a powerful 120W motor, enabling safe, efficient, and visualized fully enclosed chemical reactions.
I. Product Overview & Core Advantages
The S212 Series Double-Layer Glass Reactor is an indispensable core reaction device in modern chemical, pharmaceutical, and biological laboratories. The inner layer holds reaction solvents for stirring reactions, while the jacket can circulate different heating or cooling sources (chilled fluid, hot water, or thermal oil) for heating or cooling reactions. Its core advantages include:
-
Premium Borosilicate Glass Material: The reactor body is made of borosilicate glass, offering excellent physical and chemical properties. It can withstand drastic temperature changes and has extremely high corrosion resistance against various strong acids and alkalis, ensuring the purity and safety of the experimental process.
-
Excellent Sealing & Temperature Control Performance: Employs specialized PTFE (Teflon) bearing seal components that maintain high-precision vacuum levels during operation. The jacket design enables efficient circulation of heat exchange media for precise reaction temperature control.
-
Multi-Function Standard Opening Design: The reactor lid comes standard with "4+1" standard openings, allowing easy assembly of condensers, constant-pressure dropping funnels, thermometer sleeves, and other components, meeting complex experimental needs such as feeding, reflux, distillation, and real-time temperature measurement.
-
Intelligent Stirring System: Equipped with a 120W stirring motor. The 1L-3L models use an electronic speed control unit, while the 5L model upgrades to a variable frequency controller, ensuring smooth operation with strong torque and effectively preventing material sedimentation or uneven mixing.

III. Packaging & Shipping Information
To ensure the safety of high-value glass instruments during transportation, we implement strict logistics packaging standards:
-
Minimum Order Quantity & Custom Packaging: The minimum order quantity (MOQ) is 1 unit. The glass components and stainless steel frame of the reactor are separated and secured with high-density foam inserts, then uniformly packaged in sturdy fumigation-free wooden cases that meet export standards.
-
Shipping Time: Standard configuration models can be dispatched quickly after order confirmation and full payment. Specific voltage requirements or non-standard custom components require additional lead time assessment.
-
After-Sales Warranty Policy: Core electrical components such as the motor and control system come with a one-year warranty. Glass components are consumable parts; if any damage is found upon receipt, we will provide free replacements. After the warranty period, we offer spare parts at cost price and lifetime technical guidance.
IV. Frequently Asked Questions (FAQ)
Q: What medium should be injected into the jacket of the double-layer glass reactor? A: Different circulating media can be injected into the jacket based on your experimental temperature requirements. For low-temperature reactions, chilled fluid (such as ethylene glycol aqueous solution) can be connected; for high-temperature reactions, thermal oil or circulating hot water can be used. We recommend pairing with our circulating coolers or high-temperature heating circulators.
Q: How does the stirring system of the 5L model differ from the smaller models? A: The 5L model (S212-5L) has a larger reaction system, and material resistance may increase. Therefore, this model comes standard with a more advanced "variable frequency controller" to ensure strong torque even at low speeds. The stirrer is also upgraded to a "single-layer four-blade" design to achieve better mixing performance in larger volumes.
Q: What are the advantages of the bottom PTFE discharge valve design? A: The bottom discharge valve is made of PTFE (Teflon) material, offering extremely strong corrosion resistance. Its dead-cavity-free (no dead corner) design ensures that materials at the bottom of the reactor can fully participate in stirring and reaction. During discharge, there is minimal liquid retention, greatly facilitating product collection and reactor cleaning.
