Ghid selectie centrifuga

Alegerea unei centrifuge poate fi o provocare, piata oferindu-ne o multitudine de modele, cu specificatii diferite pentru aplicatii diferite.
Va prezentam un mic ghid pentru a va ajuta sa gasiti centrifuga perfecta aplicatiei dumneavostra.
In primul rand, trebuie sa alegeti una din cele doua mari categorii: centrifuga de masa sau de podea.
Centrifuga de podea ( Floor Standing Centrifuge)
Centrifuga de podea este selectata in general cand aveti nevoie de un volum mare zilnic, sau o viteza G-force foarte ridicata, pe care o centrifuga de masa nu o poate atinge. De asemenea pot suporta o gama larga de rotoare atunci cand aveti diferite protocoale sau aplicatii.
In general centrifuga de podea are un cost mai ridicat in comparatie cu cea de masa, dar daca nu aveti mult spatiu de lucru la masa, acest pret poate fi justificat.
Centrifuga de masa (Benchtop Centrifuge)
Nenumaratele optiuni ce le gasim la centrifugele de masa acopera o varietate de aplicatii, la un pret mult mai economic decat o centrifuga de podea.
Volumul este in general mai scazut, iar in cazul in care forta/viteza este prioritara aplicatiei dvs, centrifuga de masa nu se compara cu cea de podea.
In schimb, avem multe centrifuge foarte specializate, si puteti gasi un model specific aplicatiei dvs.
Inainte sa continuam cu urmatoarele criterii, ar mai fi 4 intrebari la care trebuie sa raspundeti:
1. De cata forta centrifugala (RCF) am nevoie?
2. Cate mostre am de procesat zilnic?
3. In ce fel de tuburi se vor afla mostrele ?
4. Am nevoie de rotor special? De ex. un unghi de inclinatie anume sau rotor basculant

Centrifuge de podea rapide / super rapide
Cu un RCF de pana la 70000 xg, acestea sunt, dupa ultracentrifuge, cele mai rapide.
Dimensiunile generoase le fac ideale pentru aplicatii ce implica multi utilizator sau protocoale.
In general dimensiunele pot fi intre 1.5 mL - 1000 mL. Datorita dimensiunii, aceste centrifuge permit o varietate mare de configuratii, iar producatorii oferta o gama mare de rotoare.
Considerati o centrifuga super rapida daca aplicatia dvs implica preparearea generala a mostrelor, separarea celulelor, culturi de tesut, izolarea corpurilor Golgi, separarea ADN/ARN.
Centrifuga de mare viteza, de masa
Cu forta asemanatoare centrifugei de podea - 50000 xg, aceasta centrifuga este capabila de multe aplicatii ce necesita o forta centrifugala ridicata cu un volum al mostrelor 1.5 mL la 200 mL. Considerati aceasta centrifuga pentru extragerea de celule, sau anumite aplicatii ADN / ARN
Ultracentrifuge Ultracentrifugele sunt cele mai rapide centrifuge de pe piata, cu forta g de pana la 1.000.000 xg. Acestea suporta o varietate de configuratii pentru a intrunii necesitatile dvs.
Volumul in general este 0.23 mL pana la 250 mL.
Alegeti ultracentrifuga daca lucrati cu ADN , proteine, fractionarea de ARN, lipoproteine, aplicatii in nanotechnologii.
Centrifuge uz general
Cu o forta in general de pana la 24000 xg si volum de la 0.2 mL la 750 mL, este ideala pentru o multitudine de aplicatii, fiind cea mai folosita centrifuga de laborator.
O singura centrifuga poate fi modificata cu un numar mare de rotoare pentru diverse aplicatii. Daca laboratorul dvs nu are mult spatiu, aceste unitati pot fi puse pe o masa de laborator. Suporta un numar foarte mare de aplicatii, cercetare ADN/ARN, extragere celule, cultura de tesut, proteine, separatii sub celulare, etc.
Cu o RCF asemanatoare categoriei de mai sus, de pana la 21000 xg, microcentrifuga este conceputa pentru mostre de la 0.2 mL la 1.5 mL. Considerati o microcentrifuga daca lucrati cu mostre de dimensiuni reduse.
Centrifuge cu viteza redusa
Sunt folosite in general in doua aplicatii: separarea celulelor intregi, sau extragerea celulelor intregi din culturi procesate in bioreactore RCF-ul este conceput pentru aplicatii ce necesita o forta centrifugala redusa, in jur de 7000 xg. Datorita aplicatiilor limitate aveti optiuni limitate in ceea ce priveste rotorul - in general suportand volum de la 1.5 mL la 2000 mL.
Este de mentional ca aceste centrifuge pot fi modificate cu rotoare speciale pentru aplicatii ale bancilor de sange.
Centrifuge Cell Washer
Acestea sunt un tip de centrifuge foarte specilizate, cu o forta de panal a 1500 xg. Sunt adesea folosite la teste antiglobulina, Rh, procedura Coombs; in general sunt folosite in laboratoare medicale, pentru "spalarea" celulelor, proteinelor, celulelor de sange
Centrifuge medicale
Sunt folosite zilnic in clinici, spitale. Se rotesc cu o forta de 4000 xg sau mai putin, si contin in general 4 .. 28 tuburi de 3mL .. 15 mL; Considerati aceasta centrifuga daca in aplicatiile dvs lucrati cu sange, urina

Before guiding yourself through the Lab Centrifuge purchasing selection criteria below, you should ask yourself four questions related to the protocol or application you intend to use this centrifuge for.
Before choosing a centrifuge, the first question you should ask is: floor standing or benchtop?
Once you’re ready to check out the latest models, link to MultiLab centrifuges main page! Narrow your search with the presented categories on the page.

Floor Standing Centrifuge
Floor Standing Centrifuges are often selected when there is either going to be a large volume of daily use or your application calls for very high G-Force speeds. They also support a very wide range of rotors so are a good choice if use of this centrifuge will likely change or need to accommodate many different or unexpected protocols.
Floor Standing Centrifuges are often priced in a higher range than their benchtop counterparts. But if you are running short on bench space, the extra cost of a floor model is well justified.
Benchtop Centrifuge
The numerous options you have when it comes to Benchtop Centrifuges means that most applications can be accommodated at a lower price point than with a floor standing model. However, your sample throughput will be lower than that of a floor standing model. And if force, like that found at the very top end of the RCF, is your top priority, Benchtop Centrifuges cannot keep up with a floor standing model. You can also find very specialized centrifuges within the benchtop category that may already be perfectly tailored to your application.
Four More Questions
Before guiding yourself through the Lab Centrifuge purchasing selection criteria below, you should ask yourself four questions related to the protocol or application you intend to use this centrifuge for:
How much Relative Centrifugal Force (RCF) do I require?
How many samples am I going to need to process per day?
What sort of tubes or microplates will the samples be contained in?
Do I require special rotors, such as fixed angle or swinging buckets?
All of these questions can be answered by looking closely at the protocol you will be following.
If you will be using this centrifuge for ever-changing protocols and general purpose lab use, choose based on the overall criteria presented to you that would accommodate most of your expected needs.

Super Speed Centrifuge
With a RCF as high as 70,000 x g, these are the second highest g-force centrifuges available.
Their large sizes also make them ideal for applications involving many users or protocols within the same unit. They typically offer a large volume range of 1.5 mL-1000 mL. Due to the size of the units, these also provide the most versatile range of configurations, with manufacturers offering a wide range of rotors. Consider a Super Speed Centrifuge if your applications involve general preparative work, such as cell separations, tissue culture, isolations of Golgi bodies and ribosomes, DNA/RNA separations and plasmid preps, to name a few.
Ultraspeed Centrifuge
The fastest centrifuges on the market are classified as Ultraspeed, with g-forces up to 1,000,000 x g. These units are also supported with a vast range of rotor configurations to meet your applications. Typical sample volumes range from 0.23 mL to 250 mL. Consider an Ultraspeed centrifuge if your application involves DNA, protein or RNA fractionation or lipoprotein flotation. Another common application is size gradient separations as well as many new nanotechnology applications.
Low Speed Centrifuge
These units are typically used in one of two specific applications; either the separation of whole cells or the whole cell harvest step when processing cultures from bioreactors. Their RCF is designed specifically for these low speed applications and usually is around 7,000 x g.
Due to the limited applications, you will only find a small choice of rotors—typically supporting volumes from 1.5 mL to 2,000 mL. Low Speed Centrifuges can also be customized with special rotors and liners to outfit them for blood banking applications.
General Purpose Centrifuge
Due to its RCF range of up to 24,000 x g and common volume granges of 0.2 mL to 750 mL, ideal for a broad range of applications, this is the most common lab centrifuge classification. A single unit can be modified through a large selection of rotors to suit many diverse applications.
If your lab is short on floor space, these units also sit nicely on an open bench.
Consider a General Purpose Benchtop Centrifuge if your applications include DNA/RNA research, cell harvesting, tissue culture, protein work and sub cellular separations. But the applications these units support is almost limitless.
With a similar RCF range as a General Purpose Centrifuge, up to 21,000 x g, what differentiates the microcentrifuge is sample size.
Microcentrifuges are tailored for 0.2 mL PCR tubes and 1.5 mL or 2.0 mL microcentrifuge tubes. Consider a Microcentrifuge if your applications are micro volume in nature, such as daily DNA and RNA work, plasmids and mini preparation kits.
High Speed Benchtop Centrifuge
With a RCF almost reaching the range of a floor model, up to 50,000 x g, this centrifuge is capable of many high speed applications at a sample volume range typically between 1.5 mL to 200 mL. You will not find as many rotor options in this unit as you would in a comparable Super Speed Floor Centrifuge. Consider a High Speed Benchtop Centrifuge for applications such as whole cell harvesting or certain DNA/RNA applications.
Cell Washer
These are very specialized centrifuges that run at 1,500 x g and are valuable instruments for washing blood cells for antigloboulin reagent tests, such as SBO compatibility, Rh testing, cross matching and the Coombs procedure. Cell Washers typically support culture tubes in 3 mL and 5 mL volumes. Consider a Cell Washer Centrifuge if the application in your clinical or medical lab includes washing away cellular debris, extraneous proteins and other constituents of the donor blood from red blood cells.
Clinical Centrifuge
This low-throughput centrifuge is used on a daily basis in most clinical labs and hospitals. They spin at an RCF of 3,000 x g or lower while holding 3 mL to 15 mL sample tubes. A typical run can process between 4 to 28 tubes. Consider a Clinical Benchtop Centrifuge if your applications include spinning blood collection tubes and urine samples at very low speeds for diagnostics.
