Sample Preparation Platform
Sample preparation is a crucial part of the entire processes of sample analysis
and detection; for example, for specific biological samples, which need to be
considered for possible changes in their biological activity, the process of the
whole experiment is prevented from being affected by the preparation.
Especially for some trace samples, the selection of an appropriate sample
preparation method will achieve twice the result with half the effort.
Freeze Dry System
Drying is an essential part of the sample preparation process. Compared with
other drying methods, after freeze-drying, the original biological, chemical and
physical properties of the sample are basically unchanged, easy for long-term
preservation. It can avoid the unrecoverable agglomeration of the particles
caused by heating and drying, and is very suitable for treating biological products
and preventing their deterioration due to high-temperature operation.
Target Preparation Device
The sample needs to be cut and polished before being examined by SEM, TEM and
LM, which is often a very time-consuming and difficult process. Because in this
process, the small size of the point of interest needs to be accurately located, Alfa
Chemistry chooses Leica EM TXP for sample preparation, which can be accurate
positioning of the target, less loss of the target area. In addition, it is also a highly
effective sample preparation tool for ion beam lapping and ultramicrotomy
TEM, SEM, AFM, and LM require the preparation of semi-thin and ultra-thin
sectioning of biological and industrial samples. The use of cryo-ultramicrotome
can quickly, reliably, and safely process frozen samples, to obtain accurate frozen
sectioning, and to meet the requirements of high-quality sectioning. It is suitable
for providing ultra-thin sectioning of various biological samples such as cells,
tissues and bacteria, as well as ultra-thin sectioning of various materials such as
polymer materials, rubber, and plastics.
