It is vital to control the temperature during the cultivation. For different samples, the optimum culturing temperature differs. Normally, for bacteria, the temperature should be 30 to 37℃; actinomycetes, 25 to 28℃; molds, 25 to 28℃; yeast, 18 to 25℃; acetobacte, 30 to 35℃; cells or tissues, 37℃.

Freeze-drying is one of the best methods for preserving food's original taste, texture, and nutritional value (compared to canning, pickling, or chemical preservation). While the process removes moisture from frozen food, some texture and flavor changes may occur when rehydrating with water.

Under normal operating conditions, solvent loss is very low, typically ≤0.5% for ethanol.

Most maintenance involves the vacuum pump - particularly oil-lubricated models require oil changes approximately every 80 cycles. Seals, gaskets, and other components need regular inspection for wear and cleaning.

Choosing a right size is crucial in buying an incubator shaker. Normally, it depends on your lab space and the samples you are going to culture. In addition, the filling volume of flasks should less than or equal to 33% of the flasks' total volume. To achieve the maximum oxygen transfer, the filling volume of flasks should be less than 10%.

Temperature plays a crucial role in the sample culturing. For different samples, the optimum culturing temperature differs. Lab1st provides shaking shaker with temperature range from 4 to 60 ℃.

• Bacteria: 30 to 37℃ for 1 to 2 days

• Actinomycetes: 25 to 28℃ for 5 to 7 days

• Molds: 25 to 28℃ for 3 to 4 days

• Yeast: 18 to 25℃

• Acetobacte: 30 to 35℃

• Cells/Tissues: 37℃

The shaking speed will affect the oxygen transfer. Excessively low shaking speed might cause a reduction in OTR, while high shaking speed might lead to the death of shear sensitive samples.

Normally, the shaking speed range is from 0 to 300 rpm. But for ELISA plate at 50mm shaking throw, the shaking speed should be higher than 250rpm. And for deep well plate at 3mm shaking throw, the shaking speed should be within 800 to 1000rpm.

The oxygen transfer rate(OTR) will be influence by the shaking throw. 25mm shaking throw is suitable for 25mL to 2000mL flasks, and 50mm shaking throw is for 2000mL to 5000mL flasks.

The PH of the culture medium is related to the CO2 concentration. Normally the CO2 concentration should be within 0 to 20%.

Humidity control and light control are also essential parts in the cultivation. Molds and yeast require a high humidity (about 85%), while the humidity for culturing cells and tissues will be higher(＞90%)

Regular maintenance is essential to ensure chambers operate effectively and reliably. This includes calibrating sensors, checking seals, cleaning internal components, and verifying control system accuracy.

The term "bioreactor" is usually associated with the culture of suspended mammalian cells, while "fermenter" is used to provide an environment suitable for the production of products, but is limited to microbial use.

It depends. For some basic process with low gas requirements, people usually use "air + O2" via a sparger [recommend BR-M series]. To meet more demanding processes requiring multiple gases, BR-C series with a combination of sparger and overlay is a better choice. It It provides a variety of gas combinations [air, O2, CO2 and N2] that can be controlled by MFC.

The most common way is using an SPARGER, which bubbles the air from the bottom of the culture vessel. For mammalian cells, overlay is often combined with sparger aeration, as oxygen mass transfer is not as efficient as in microbial cultures, which is due to lower stirring rates to avoid shear stress (which reduces the percentage of dissolved oxygen), larger cell size, etc.

The gas supply to the bioreactor must be free of microorganisms, so the pipeline must be equipped with a sterilizable 0.2um filter.

Standard with 6-blade Rushton impeller for microbial fermentation and marine [elephant ear] propeller for cell culture. Customizable blades for your choice, such as Spin filter, Cell-lift impeller, Basket impeller, Pitched blade impeller, Marine blade impeller, etc.

• Molecular distillation is the same as short path distillation. Both imply the use of a high vacuum and a condensing surface close to a heated evaporating surface. However, "short path distillation kit" usually refer to with a basic glassware setup consisting of a basic boiling flask with a neck leading to a condenser and receiving flask, or a similar variation called a KIugelrohr.

• Purpose: Wiped film distillation is geared towards continuous operation and high throughput of liquids with a wide range of viscosities, offering high efficiency in separating volatile compounds. Short path distillation is more focused on batch processing of thermally sensitive or high boiling point substances, ensuring minimal degradation.

• Design and Operation: Wiped film distillation utilizes a rotating wiper blade to create a thin film of liquid, whereas short path distillation involves creating a short path between the heated flask and the condenser to minimize vapor travel distance.

• Applications: Wiped film distillation is suitable for industrial-scale operations requiring high purity and efficiency, while short path distillation kit is often used in research, small-scale production, and refining processes where maintaining compound integrity is crucial.

• Pharmaceuticals: Purification of pharmaceutical compounds, separation of omega-3 fatty acids, vitamin distillation.

• Food Processing: Extraction of essential oils from plants, fractionation of fatty acids, concentration of natural flavors.

• Chemical Industry: Refinement of high-purity solvents, separation of high-boiling-point chemicals, production of specialty chemicals.

• Environmental Remediation: Recovery of volatile organic compounds, treatment of hazardous waste, recycling of industrial solvents.

• Nutraceuticals: Extraction and concentration of bioactive compounds, purification of nutritional supplements.

When purchasing a freeze dryer, consider factors such as the processing capacity, the types of materials you intend to freeze-dry, energy efficiency, and the overall cost of ownership.

Drying a sample usually takes around 24 hours, though this can vary based on the material, and precise timings may differ. Models with heating functions can expedite the process, typically completing it in under 20 hours. The slower drying speed of freeze dryers is a characteristic of the freeze-drying process itself, not a flaw in the machine.

The processing capacity is based on the surface area of the freeze dryer trays. But different products differ in the density, concentration, so the processing capacity differs. Please contact us and send us the product you need to process, our engineer will work out for you.

During the freeze-drying process, the entire system operates under vacuum, so manual intervention is not possible. However, machines equipped with external bottles allow for sample retrieval.

We offer one-year warranty and life-time support like setup assistance, troubleshooting and maintenance tips for you.
