To successfully achieve freeze-drying, various factors must be effectively combined. The "Freeze-Drying Guide" is a handbook for realizing proper freeze-drying. It focuses on hardware explanations and describes important parameters and procedures for sample pretreatment. It also explains the parameters of the drying process in freeze-drying and how to perform freeze-drying on samples that include solvents other than water. [Contents (excerpt)] ■ How to choose the right equipment for your needs ■ The relationship between the temperature of the cooling condenser and the drying rate ■ The importance of equipment maintenance ■ Vacuum pumps - types and maintenance - ■ The importance of freezing *For more details, please refer to the PDF document or feel free to contact us.

This poster introduces tips on how to shorten the working time involved in "freeze-drying" while ensuring it is done "reliably." It includes topics such as "the freeze-drying process," "effective process control," "requirements for vacuum pumps," and "detection of the end point of drying." We encourage you to take a look. 【Contents (partial)】 ■ Shortening experimental work time through optimization of process parameters ■ Effective process control ■ Cooling condenser ■ Requirements for vacuum pumps ■ Correlation between temperature and vapor pressure of ice *For more details, please refer to the PDF document or feel free to contact us.

The "Lyovapor L-200Pro/L-200" is a freeze dryer suitable for research and development prior to production. The "L-200Pro" is a compact tabletop model for laboratory use, yet it has control functions equivalent to those of large-scale pilot production machines, allowing for efficient and smooth preliminary testing. Additionally, the shelves where samples are placed are equipped with built-in heaters, which independently supply thermal energy lost from the samples during sublimation at each shelf level, achieving accurate control with good reproducibility and fast drying processes. 【Features】 ■ Ideal for process control and development of freeze drying ■ Intuitive and easy operation ■ Adjustable angle ■ Supports Japanese language display ■ Freely customizable according to usage purposes *For more details, please refer to the PDF materials or feel free to contact us.

The "Lyovapor L-300Pro/L-300" is a freeze dryer with unlimited processing capacity. The "L-300" has no restrictions on the "amount" that can be continuously operated, and it regularly removes ice from two cooling condensers without interrupting the freeze-drying process in a vacuum state. Additionally, the adhered ice is alternately removed at regular intervals, keeping the cooling surfaces exposed without being covered by thick ice, which consistently maintains high cooling capacity and significantly contributes to speeding up the freeze-drying process. 【Features】 ■ No upper limit on trap capacity ■ Intuitive and easy operation ■ Adjustable angle ■ Japanese language support ■ Freely customizable according to usage purposes *For more details, please refer to the PDF document or feel free to contact us.

The "Lyovapor L-250/L-250Pro" is a freeze dryer equipped with a cooling condenser that reaches -85°C. It is suitable for samples that may contain residual organic solvents such as acetonitrile, and is also ideal for samples that are easy to melt. Additionally, it uses a non-fluorinated device that has a low environmental impact. 【Features】 ■ Maximum dehumidification capacity: 5kg ■ Compatible with samples that may contain residual organic solvents ■ Uses environmentally friendly non-fluorinated substances ■ Graphical display of the drying process ■ Detection of drying endpoint for flask samples ■ Remote control and monitoring *For more details, please refer to the PDF document or feel free to contact us.
