One-Stop Solution: From Synthesis to Sample Concentration

Why “Device Collaboration” is Needed From Standalone Device Procurement to System Integration

In the day-to-day operations of a laboratory, no single piece of equipment operates in isolation. A complete concentration and purification experiment typically requires multiple pieces of equipment to operate in coordination under precise timing and parameter control.

• Reactor are used to carry out the entire synthesis process.

• Rotary evaporators perform reduced-pressure distillation and concentration of solvents under vacuum conditions.

• Vacuum pump provides a continuous and stable negative pressure environment for the entire system.

• Condenser water circulators supply a cooling medium that maintains a constant low temperature to the condenser tubes.

• Subsequent testing will require the use of corresponding analytical equipment.

SCITEK offers a comprehensive product portfolio designed to address these needs, enabling reactors, rotary evaporators, vacuum centrifugal concentrators, and vacuum equipment to be flexibly integrated into a range of end-to-end workflows.

The one-stop reaction and evaporation solution is built on the core concept of flexible configuration, integrating five key processes, reaction synthesis, evaporation and concentration, vacuum supply, intelligent control, and cooling and temperature control into a comprehensive equipment system.

Sample Pre-Treatment

Sample preparation is the first step in the experimental process.

SCITEK provides a wide range of sample‑pretreatment instruments.

Reactor Systems

As the starting point of the entire process, we offer three reaction environments.

• High-temperature.

• High-pressure sealed reactions.

• High-speed emulsification and homogenization reactions.

A suitable reactor platform is an indispensable foundation for laboratory synthesis workflows. Serving as an upstream processing unit, the reactor can be logically integrated with subsequent evaporation, concentration, and analytical testing processes to establish a complete experimental workflow spanning from chemical synthesis to product characterization.

SCITEK offers complete range of reaction platforms in various sizes and types.

Evaporation & Concentration

Once the reaction is complete, it is necessary to remove the solvent, increase the product concentration, or recover the solvent. The rotary evaporator is where your product is gently concentrated — removing solvent quickly and safely under vacuum, so your sample stays intact[1].

Rotary and Centrifugal Concentrator

SCITEK evaporators cover the full range of models: from entry-level to high-end, multifunctional units, allowing users to choose freely based on throughput and the level of automation.

Alternatively, you can choose a vacuum centrifugal concentrator—which handles small volumes, multiple samples, and parallel processing—to meet your various experimental needs.

Vacuum pump

Why is it necessary to use a vacuum pump?

Evaporator should be operated at high pressure, if possible, as in this way the vapours can be used to the best possible extent[2]. Evaporators rely on vacuum pumps to reduce the pressure inside the system. The reduced pressure lowers the boiling point of the solvent, allowing distillation to be carried out at relatively low bath temperatures.

SCITEK offers many types of vacuum pumps: cost-efficient options for standard lab work, and corrosion-resistant solutions engineered for professional, chemically demanding processes.

Vacuum control

What role does a vacuum controller play?

It serves as the “brain” of the vacuum system, precisely regulating pressure to ensure that every evaporation process is stable, repeatable, and safe. A vacuum pump can only provide a maximum pumping speed but cannot continuously maintain the system’s target vacuum level. Without a vacuum controller, the vacuum level would drift and fluctuate, causing the evaporation process to become unstable, making experimental results difficult to replicate, and potentially leading to bubbles or foaming that could damage the sample.

The VC100 vacuum controller upgrades vacuum regulation to programmable automatic control, serving as a key component for improving the reproducibility of concentration, preventing boil-offs, and saving energy.

Vacuum Controller

Vacuum Setting Range : 1–1000 mbar

Temperature control

Reactions need temperature control, evaporation needs condensation, and solvent recovery needs low temperatures.

SCITEK recirculating chillers and circulators provide precise temperature assurance for the entire workflow.

Freeze Dry

Vacuum concentration removes most of the solvent, yielding a viscous paste; freeze-drying removes the residual solvent by encapsulating the sample and allowing it to sublimate at low temperatures, producing a resolvable, active dry powder, thereby avoiding sample damage caused by heating and splashing.

Analytical Instrument Portfolio

After samples undergo pretreatment, such as reaction and concentration ndustries including pharmaceuticals, fine chemicals, and new materials each have specific requirements for component separation, quantitative analysis, and impurity analysis.

SCITEK offers analytical instruments such as HPLC, GC, UV-Vis, FTIR and etc.
