Elektroforesesystemer

Supplier: VWR Collection

shiroGEL horisontale elektroforesesystemer og tilbehør er udviklet til men og sikker brug, og er bygget til at kunne holde til sliddet ved daglig brug. For at sikre mod lækager er gelkar og gelbakker støbt i tyk akryl. UV-transparente gelbakker hjælper til visualisering af prøverne. Kassetter beskytter elektroderne og gør udskiftning nemt. Gelstøbning er enkelt ved hjælp af de robuste støbningsindløb af gummi. Slots i bakkernes sider gør det nemt at placere kammene. Kammenes todelte design giver den vertikale indstilling, så brugeren har kontrol over brøndenes dybde. De kamme, som leveres sammen med systemerne, er 1,5 mm tykke. Der fås flere kamme, herunder nogle, som er kompatible med multikanalpipetter og med forskellig tykkelse. "EasyLift" låget på gelkarret er let at tage af ved hjælp af sidefligene og trykpunkterne. Låget er hvælvet for at hindre, at kondens drypper ned på gelen, og det er omgivet af en drypring til opsamling af kondens, så bufferkoncentrationen opretholdes.

shiroGEL Mini Vertical PAGE er modulært system, som gør det muligt at udføre PAGE og elektroblotting i samme tank ved ganske enkelt at skifte indsatserne. Med systemet følger indsatser til hver applikation og en fælles buffertank, som processerne foregår i. Hver indsats har sin egen monterede elektrode, som er forbundet til låget på buffertanken. Af sikkerhedsmæssige årsager er ledningerne forbundet direkte med låget. Når låget aftages, frakobles strømmen til systemet. Indsatsene har desuden en lille pude, som passer til lågets placering. Den sikrer, at lågen altid er placeret korrekt og gør det nemmere at aftage. Buffertanken er støbt for at forhindre separation og lækage. En lang række spacere, kamme og andet tilbehør er tilgængeligt for individuel tilpasning af systemet. Alle spacere og kamme er farvekodede eller har tydelig størrelsesangivelse.

The shiroGEL vertical 20 offers application flexibility and is distinguished by its ease of gel casting and set-up, requiring only four screws to secure up to four 20×20 cm gels. This vertical screw clamp technology distributes pressure evenly along the height of gel rather than in the centre to eliminate plate bowing and gel compression, while maintaining a leakproof seal during casting. A built-in inner buffer chamber within the PAGE insert allows set up to be completed without inclusion of an upper buffer chamber. These systems are ideal for 1D and 2D SDS-PAGE, native, preparative, gradient and high resolution nucleic acid electrophoresis.

This 96-well format horizontal gel electrophoresis unit is compatible with 8-channel multichannel pipettes, and matches up with a standard 96-well plate configuration.

The smallest of all the PerfectBlue electrophoresis systems, the Mini S can be used for up to 24 samples enabling short and rapid sample separation. This model includes all the features of the larger models, including direct chamber gel casting and embedded platinum electrodes, and is supplied ready to use with lid, power leads, two combs and a gel tray with an easy to read ruler.

Supplier: VWR Collection

The PerfectBlue Mini M electrophoresis system is a very convenient size for a wide range of routine uses. Supplied with two combs, but with a wide range of standard and microtitre combs available, this system can be used for the separation of up to 36 samples. The system comes 'ready to use' with lid, power leads and a gel tray. Its high specification construction and embedded platinum electrodes provide high quality results time after time.

Supplier: VWR Collection

Capable of running 12×14 cm gels, the largest of the 'Mini' range still offers the convenience of direct gel casting in the tray, in an easy to manage product size for reliable, high quality electrophoresis. This system can be supplied with a choice of gel trays suitable for 2, 4 or 12 combs, and an expansive range of standard and microtitre combs, making this versatile system appropriate for both routine and small separation electrophoresis.

The 'Revolution' series includes a buffer circulation system, powered by the electrodes themselves. Hydrogen bubbles produced at the cathode pass up a diagonally positioned pipe connected to the two sides of the tank producing a gentle circulation of the buffer. The result is no pH and ionic gradient – without need of mechanical pumps.

Supplier: VWR Collection

Capable of rapidly running up to 160 samples, the Midi S is a compact, but highly efficient, electrophoresis system. Versatility is built-in, with six different comb positions and a choice of 10 different comb types and thicknesses available. For rapid handling, special microtitre combs enable rapid loading with a multichannel pipette, while the effective rubber sealed 'end gates' allow gel pouring right in the tray. With its sturdy design and straight electrodes, the results are clear, crisp and quick, free from 'smiling' bands.

With its extra wide design, the Midi ExW is ideal when there is a need to run lots of samples (up to 200) in just a short distance, for example, when genotyping. This format, along with its compact footprint, offers rapid run times without compromising on power. The result is a system for high throughput sample processing, generating crisp clear band data. As with all PerfectBlue gel systems, gels can be poured directly in the trays at temperatures up to +60 °C. With the Midi ExW, the trays can be walled with effective gasketed 'end gates' which are supplied in the system. In addition, gel size can be reduced by using wall combs or the aluminium casting dam.

The JustCast system is a flexible and quick system for casting multiple PerfectBlue™ compatible 'mini' gels at the same time, without the need to tape. Adjustable to fit all gel trays featured in the PerfectBlue™ mini gel series, this system comes fitted with an easy to read bubble level and adjustable feet to ensure a level casting of the gel. At any one time, the system can fit three Mini S, two Mini M or two Mini L trays.

The smallest of the Maxi series, the Maxi S Plus is suitable for high quality sample separation of up to 160 samples per run. With this flexible system, the gel size can be split into two, three or four sections by using different comb positions, plus the gel size can be reduced using the wall comb or the casting dam system.

Supplier: VWR Collection

Wider than the Maxi S Plus, the Maxi M model can accommodate up to 168 samples but still with an economical footprint.

Supplier: VWR Collection

Based on the Maxi M model, the Maxi M 'Revolution' offers a built-in buffer circulation system, powered by the system’s electrodes. At the cathode, hydrogen bubbles are produced and pass up a diagonally positioned pipe connected to the two sides of the tank to produce a gentle and continual circulation of the buffer. The system nulls any pH and ionic gradient – without the fuss of mechanical pumps. The system offers 6 comb positions enabling the gel to be partitioned into 2, 3 or 4 areas. In addition, the system can accommodate any of the 23 standard and microtitre comb designs described for the Maxi M model.

Supplier: VWR Collection

This 'extra wide' Maxi tank was developed especially for large sample numbers and rapid separation times. Accommodating up to 10 microtitre combs, the Maxi ExW can be used to separate up to 500 samples and facilitates error-free loading with multichannel pipettes. By optimising the position of the embedded platinum electrode and the use of the three-point levelling platform, with in-built bubble level, the Maxi ExW provides highly reproducible and dependable sample separation, free from 'smiling' effects.

Supplier: VWR Collection

The Maxi ExW 'Revolution' offers built-in buffer recirculation - without the need for pumps or additional tubing. The Maxi ExW 'Revolution' offers the same high throughput, rapid separation as the Maxi ExW model but, with the position of the cathode and a rising tube, the system uses hydrogen bubbles to slowly mix the buffer. This system thereby avoids the build-up of pH or ionic gradients for electrophoresis of maximum quality and stability.
