Q: What’s the difference between single-layer and double-layer glass reactors?

A: The single-layer glass reactor can directly heat or cool, which is similar to the water and oil bath. But it’s inferior in temperature control aspect. The double-layer glass reactor has interlayer between two layers. The water or oil can be injected through the temperature control equipment to form a circulating system. It will have a better and more accurate temperature control whether for heating or cooling.

Q: Which one to choose, single-layer glass reactor or double-layer glass reactor?

A: It depends on their differences, heating and cooling conditions.

Q: What is the glass material of the reactor?

A: Full set of glass part adopts G3.3 borosilicate glass, with excellent chemical and physical properties.

Q: What kind of circumstance is it applicable for?

A: It is applicable for a wide temperature range from -80℃ to 200℃.

Q: Is it easy to clean the reaction kettle?

A: It is convenient to clean with the large cleaning port.

Q: What kind of payment terms do you accept?

A: Normally we accept TT, Paypal, Western Union, Alibaba Escrow, and L/C. The exact term will be discussed during the deal.

Q: How will you delivery these goods?

A: It will depend on your quantity. Normally we will choose International Express, air and sea freight.

Q: How do you package products?
