Zls-4 Vacuum Centrifuge Concentration System Chemical Analysis Experiment Equipment Sample Concentration Centrifuge Vacu

Sample evaporation, drying, concentration and purification methods, commonly used are:

● Distillation and rotary evaporation methods at high temperature and near atmospheric pressure conditions, but can only handle a single sample;

● In low temperature and high vacuum conditions of freeze drying method, although sublimation can maintain the sample activity, but more time-consuming;

● Rapid evaporation at low temperature, nitrogen blowing instrument method, but can only deal with a small number of samples, the use of high cost, troublesome operation;

● Evaporation under room temperature vacuum conditions, vacuum centrifugal concentration method, sample solvent evaporation faster;

Evaporation is an endothermic process, in the sample water evaporation will take away the heat of the product, so as to reduce the temperature of the product itself, in order to maintain the sample properties and activity. However, in order to accelerate the evaporation rate, the equipment needs to provide the heat needed to absorb evaporation, generally through cavity heating or infrared heating, especially suitable for concentration and purification of heat-sensitive biological samples or clinical drugs.

Vacuum centrifugal concentrator provides medium speed (1500~2000r/min), the corresponding centrifugal force can prevent sample dispersion and burst boiling, can be collected by cold trap solvent reuse.

Economical and efficient vacuum centrifugal concentrator

● The sample does not produce foam, the least sample loss

● Drying various samples at the same time

● All samples are concentrated at the bottom of the centrifugal tube

● Suitable for drying 1 ml to 3000 ml samples

● Repeatable drying by controlling process parameters, such as rotor chamber temperature

(Provides evaporation energy) and vacuum (automatically sets optimal pressure)

● Safe and simple solvent recovery

Range of application

●DNA/RNA(solvent is mainly water, ethanol, methanol)

● Oligopolymer or peptide

Low PCR products

● High performance liquid chromatography (HPLC) products

● Synthesis and separation of organic substrates

● Substrate preservation and processing

● Chemical synthesis

● High throughput Screening (HTS)

● Toxicological identification, forensic identification

● Analysis of food and environmental samples

● Universal laboratory evaporation

Vacuum centrifugal concentration system has the function of fast and safe evaporation of water and organic solvents in the sample. The processed samples can be easily used in various qualitative and quantitative analytical chemistry, biochemistry, biological analysis, immune screening, food safety, residue analysis, etc.

Suitable for immunoglobulin concentration, drug metabolite concentration, SPE solid phase extraction, liquid chromatography before and after treatment, ADMET/ toxicology, polymer chemistry, DNA/RNA purification concentration, oligopolymerization, forensic medicine/drug abuse testing, general laboratory concentration.
