This hood is equipped with a main carbon filter and a secondary HEPA filter located at the exhaust. This unit is suitable for cleanroom applications and for handling chemicals in powdered/ solid form.
Quantify nucleic acids and proteins. This device is magnificent! With only 1µl it can tell the concentration of DNA, RNA, protein sample and assess it purity also.
Amplify a specific sequence of DNA. The concept of PCR relies on generating copies of a sequence of DNA through repeating cycles of three main temperature-dependent steps (denaturation, annealing and extension) in presence of DNA polymerase, primers, and dNTPs. The production of the PRC can be analyzed using other techniques.
Determines the exact amounts (relative or absolute) of amplified DNA/cDNA. qPCR follows the exact procedure of PCR, but they differ in the way and time of detection. In qPCR, DNA is fluorescently labeled which allows direct measurement of the amplified DNA at any time. The density of fluorescence increases with increase in number of amplified DNA.
Preparation, running and blotting of proteins. The module contains an apparatus that holds gel cassette firmly to help in preparation of SDS-polyacrylamide gel and prevent leakage. The XCell SureLock Mini-Cell is used to run the SDS gel, while the XCell II Blot Module is used to transfer proteins from the gel to a nitrocellulose membrane. Both modules contain electrodes that create a uniform electrical field which allow movement of proteins in the desired direction.
Gel electrophoresis is an analytical technique used to separate nucleic acid molecules (DNA or RNA) based on size.In gel electrophoresis, the molecules to be separated are pushed by an electrical field through a gel that contains small pores. The molecules travel through the pores in the gel at a speed that is inversely related to their lengths. This means that a small DNA molecule will travel a greater distance through the gel than will a larger DNA molecule.
Helps in visualization of nucleic acids in gels. The transilluminator emits UV radiation that pass through the gels to show DNA, and RNA after electrophoresis.
A gel contains a stain that when exposed to UV ignites showing the bands of nucleic acids it contains. Similarly, HRP-labelled proteins in a cellulose membrane illuminate at a particular wavelength. These bands can be then quantified.
A centrifugal force is applied on a mixture at a fixed axis (rotor) to precipitate the heavier components at the bottom of the solution while allowing the lighter components to float on the surface of the solution.
HPLC is an analytical technique to separate, identify, and quantify components in a mixture. The components of a mixture are separated from each other due to their different degrees of interaction with the absorbent particles. This causes different elution rates for the different components and leads to the separation of the components as they flow out the column
Molecules have different absorbance and emission capabilities, which can be related to the cell characteristics such as viability and integrity. This spectrophotometer provides unlimited wavelength selection, measurement at low UV to visible wavelengths and both cuvette and microplate reading capabilities. Measurement of the absorbance of molecules provide information about quantity and purity of molecules. |
Fluoroskan readers measure the light signals emitted in relative fluorescence units. First, a specific wavelength is used by the excitation system to illuminate the sample. Then the light signals of the illuminated sample are collected by the emission system and separated from those of the excitation light. The signals are measured by a light detector.
This method is used to remove excess solvent from extract at elevated temperature and reduced pressure. This helps in obtaining pure yields of extracts.
It gives pH value from 0 to 14 with a resolution of 0.01. The reading is displayed as 7 digits (3 digits for temperature and 4 digits for pH).
Tap water goes through a pressure reducer then enters the ultrapure water system to monito the electrical conductivity. The entered water then goes through UV-photooxidation and a filter cartridge and then this water goes through another filtration module to a special conductivity that measures cell equipped with temperature compensation. Finally, the treated water goes through a sterile filter once dispensed out through the ultrapure water outlet.

The automated freezer is a closed chamber that keeps the items within it in at ultra-low temperature -80deg C
Its concept is similar to that of MultiSkan Spectrum. It detects light signals produced by a sample, converted by a sample, or transmitted through a sample. The signal is measured by a detector, which convert photons into electricity that is then quantified by the microplate reader. The output of this process is numbers by which a sample is quantified.
Unlike inverted microscopes, the light source and the condenser are found below the stage, while the magnification objectives located on the top of the stage.
In the inverted microscope, the light source and the condenser are on the top of the stage while the magnification objectives are located below the cell-carrying stage. The location of the objectives allows better observation of bottom-adhering cells and provides a sterile working area. These objectives can increase the image 10X, 20X or 40X.
All centrifuges have the same working concept. This centrifuge can centrifuge different types of tubes (1.5ml, 5ml and 50ml tubes). Moreover, it has a cooling system and thus centrifugation can be performed at various temperature (-10 to 40 degree Celsius).
It is used for sterilization of bacterial pathogens, decontaminating biological waste materials, sterilization of culture media and labware.
The equipment has a dual purpose which can be controlled by temperature. It is specifically designed for incubating culture plates to facilitate the growth of bacterial pathogens. The second use is for sterilizing materials such as glassware, sealed containers etc.
Infectious specimens are handled within this equipment to protect laboratory workers and the environment from harmful biological agents during culture and other procedures. It also prevents biological materials inside it from being contaminated.
