-75°C Insitu Vacuum Freeze Drying Machine; Silicone Oil heating

Hawach is an experienced vacuum freeze dryer manufacturers. According to the requirements of our clients, it can help you to choose the most suitable product to save time. For the freeze drying machine price, We also give the best price to support our clients.

Hawach currently has a full range of freeze dryer lab equipment, which can be divided into ordinary splits, heating splits, in-situ electric heating, and in-situ silicone oil heating vacuum freeze drying machine. The temperature range is also very wide, with -50 small freeze dryer, -55, -56 lyophilization machine, -60 scientific freeze dryer, -75, -80 benchtop manifold freeze dryer
degrees optional.

At the same time, there are also different cost-effective options in the selection of screens, including digital display, liquid crystal display, and home position. The application range is also very wide, both experimental and pilot.

Although vacuum freeze drying machine types are different, Hawach has always strictly controlled all aspects to let the product quality speak and give back to customers. As a specialist vacuum freeze dryer manufacturers, Hawach provider our customer a reasonable freeze drying machine price. The following steps must be performed before the official shipment:

1. After the components of the vacuum freeze drying machine are manufactured, they will be visually inspected and tested before entering the assembly stage.
2. Ensure that the drying room is transparent and smooth without scratches; the material tray is clean and tidy without residue, and the surface is smooth and flat;
3. The inside of the cold trap must also be smooth, flat, and free of scratches, and it must be sealed with the edge of the host without gaps;
4. There is no gap at the joint between the glass cover and the cover plate, and the tightness is high.
5. After the product is assembled, the test runs the entire product and troubleshoot.
6. Observe the cooling rate (reduced by 1 degree per minute after reaching the set temperature), the degree of vacuum (which can reach the theoretical degree of vacuum), and the accuracy of temperature control (PT100 accurate temperature display).

As a qualified vacuum freeze dryer manufacturers, you can go further only if you strictly control the product quality. We know that quality and freeze drying machine prices are always the most important issues for customers. So we will definitely provide the best quality products at the most suitable freeze drying machine price. I believe Hawach is worth you trying. Our freeze drying machine price is highly competitive when considering the quality.

The characteristics of electric heating and silicone oil heating are as follows

The shelf cooling of the electric heating freeze dryer lab equipment is directly from the evaporation end of the compressor, so the refrigeration is rapid and the temperature is low. During heating, due to the rapid cooling, the cooling and heating conflicts, the temperature control is not particularly uniform, and the temperature error will be slightly larger.

For example, the shelf is controlled at -20 degrees. When the cooling end is opened, it is extremely possible to instantly drop to -30 degrees, and then slowly rise to -20 degrees through the heating plate. Electric heating heats up faster, causing rapid cooling and rapid heating. Generally, temperature-sensitive materials cause melting or collapse, and some drugs may be inactivated. Therefore, it is recommended that the temperature-sensitive materials should be freeze-dried without electric heating.

Compared with the electric heating in-situ freeze dryer lab equipment, the silicone oil in-situ vacuum freeze drying machine has superior performance. The vacuum freeze drying machine with silicone oil as the medium is very reliable in cooling and heating. Silicon oil heating in-situ freeze dryer maintains the original characteristics of the in-situ freeze dryer. At the same time, silicone oil is used as a circulating medium, with high temperature control accuracy, shelf temperature difference ≤1 ° C, uniform drying effect, and can better maintain the characteristics of the material. Therefore, which type of in-situ freeze dryer is selected must be determined according to the nature of the freeze-dried product.
