Frequently Asked Questions
You need to focus on the following factors when searching Reliable Rotary Evaporator Manufacturer in China.
Quality Control
This is most important as there is no unified standard for rotary evaporators in China.
You should pay attention to how the manufacturer control their raw material and manufacturing quality.
A reliable manufacturer will use superior quality raw material to produce rotary evaporators and glass reactors.
Research & Development Ability
Here is the truth:
Lab equipment need upgrade to meet the latest technology.
Manufacturer with strong R&D capability can provide advanced rotary evaporators and glass reactors to improve your usage experience.
Factory Management
rotary evaporators and glass reactors production need whole manufacturing equipment line.
A reliable rotary evaporators and glass reactors manufacturer will use high efficiency processing machine and management way to ensure product quality & cut down production cost.
Based on internet, the rotary evaporator might cost you at least $1200.
But this is not the real case.
There is not a fixed price on rotary evaporators from different brands and types.
You need to figure out the following issues when buying rotary evaporators.
Rotary Evaporators Types
Look:
There’re many types for rotary evaporators such as ordinary type and explosion proof type.
You will pay more for explosion proof rotary evaporators than general rotary evaporators.
Rotary Evaporators Capacity
You can choose 0.5L, 1L, 10L or even 100L rotary evaporators.
However, you have to spend more money on larger capacity rotary evaporators.
Rotary Evaporators Materials
This factor is easily neglected by most rotary evaporators importers.
You might be wondering:
Why this company is more expensive than that company?
Actually the quality of raw material decides the rotary evaporators price.
Rotary evaporators made of higher grade material usually cost more than ordinary material type.
The bottom line?
You should not just consider the price when sourcing rotary evaporators in China.
Instead, safety, quality and raw material grade is the first concern you need care.
You need to figure out the following questions before choosing suitable rotary evaporators.
The Rotary Evaporators Volume
You need to know the capacity of rotary evaporators as different capacity will impact your work efficiency.
The Temperature of Heating Bath
The general heating temperature is 60℃, you will require customized rotary evaporators if your heating temperature is higher than it.
Evaporating Flask Speed
The higher the rotating speed , the larger the heating area will be.
You should also know the rotating speed for your rotary evaporators.
Here are tips on operating glass reactor needs
1. Check whether the medium corrodes the main material
Look:
The medium impact your choice of glass reactor.
You will have to customize glass reactors if there’s severely corrosive reaction.
2. When loading the reaction medium, it should not exceed 2/3 of the liquid level of the kettle body.
3. It is strictly forbidden for the glass reactor to work under the condition of overpressure and overtemperature.
4. Be careful not to mix water or other liquids when adding heat transfer oil.
5. Connect the corresponding voltage according to the operating voltage of the controller.
6. When the final reaction temperature is determined, it is not allowed to change the temperature setting value during the heating process to avoid a large overshoot of the temperature
Yes, you can.
Rotary Evaporators and Glass Reactors manufacturers with strong development ability can customize the function for your case.
You need to provide your process flow, material viscosity & temperature and working time so the manufacturer can tailor your rotary evaporators and glass reactors accordingly.
If you can’t provide drawing, rotary evaporators and glass reactors manufacturer will discuss with you about the size issues.
