Sentrifugit ja orgaanisen näytteen teko (SPE)
Kemiallisessa analytiikassa näyte koostuu aina sekä itse havaittavasta aineesta (näyte), että sitä ympäröivästä väliaineesta (matriisi). Sentrifugointi ja kiinteäfaasiuutto ovat näytteiden esikäsittelymenetelmiä, joilla helpotetaan tai mahdollistetaan analyysi monimutkaisesta, mittausta häiritsevästä matriisista.
Sentrifugi kaikkiin käyttökohteisiin
Sentrifugeja käytetään nesteen ja kiintoaineen erotteluun toisistaan monilla eri aloilla, kuten ympäristö-, elintarvike-, lääkeaine-, ja kliinisessä kemiassa.
LabTech Gyrozen -sentrifugisarja tarjoaa laajan skaalan sentrifugeja moniin eri tarpeisiin laboratorioihin, pienistä pöytämalleista aina lattialla seisoviin, ison kapasiteetin laitteistoihin.
Välineet kiinteäfaasiuuttoon
Kiinteäfaasiuutto (solid phase extraction, SPE) on kemian alan menetelmä erotella ja väkevöidä näytteitä liuenneesta faasista. SPE:ssä nestemäinen näyte puhdistetaan joko sitomalla analyytti tai häiritsevä aine patruunaan, ja tällä tavalla puhdistetaan näyte häiriötekijöistä itse analyyttiä varten.
SPE on usein hyvin käsityövaltainen työvaihe, mutta LabTech tarjoaa myös useita eri automatisoituja SPE-laitteistoja. Laitteistoja on eri kokoisille patruunoille, sekä myös SPE kiekoille, ja eri näytemäärille sopivina.
Sentrifugit
Labtech’s range virtually satisfies the needs of any modern lab with its 14 models divided in 4 families covering low and high speed, ventilated and refrigerated, small and large capacity, bench top and floor standing models supported by an incredible array of accessories that provide flexibility and versatility.
Best by design, quality and flexibility
When the Dutch physicist Christiaan Huygens coined for the first time the term “centrifugal force” in his DeVi Centrifuga published in 1659 he could not imagine what an innovation he brought into the scientific world. Lot of time has passed since then with a succession of discoveries and improvements such as the Nobel Prize awarded to Theodore Svedberg for the invention of the ultracentrifuge (some 900.000 xg!) in 1926
or the first floor standing unit with refrigeration introduced by Ivan Sorvall in 1955. It is even thanks to those pioneers that nowadays laboratory centrifuges are crucial instruments in countless applications from genetic engineering to hematology, from drug discovery to pathology, from marine science to agriculture, and you name it.

Orgaaninisen näytteen teko (SPE)
Solid-phase extraction, commonly referred to the acronym SPE, is an extraction technique that uses the affinity of a solid substance (solid phase), generally packed in columns or disks, with one or more substances present in a more or less complex matrix.
Best by design and flexibility
The Solid-Phase Extraction (SPE) sample preparation method was developed by a combination of extraction and chromatography. It is mainly used for separation, purification, and concentration of samples. It has found applications in environmental protection, food, petrochemical, clinical drug analysis, life sciences, etc.
