Lo spettrofotometro Go Direct SpectroVis Plus misura rapidamente l'intera lunghezza d'onda. Si collega direttamente alla piattaforma in modalità wireless tramite Bluetooth® o cablato via USB.
Introducete i vostri studenti alla spettroscopia con l'economico spettrofotometro Go Direct SpectroVis Plus. In grado di collegarsi wireless o via USB, questo dispositivo può facilmente raccogliere l'intera lunghezza d'onda (assorbanza, trasmissione percentuale o intensità) in meno di un secondo. Una volta determinata la lunghezza d'onda di picco, è possibile stabilire la concentrazione di una soluzione (legge di Beer) o monitorare la velocità di reazione. Un percorso luminoso ridotto consente allo spettrofotometro Go Direct SpectroVis Plus di essere utilizzato per microlaboratori e applicazioni biochimiche con micro e semi-micro cuvette.
Lo spettrofotometro Go Direct SpectroVis Plus può essere utilizzato in diversi esperimenti di spettroscopia:
Determinare la lunghezza d'onda del picco per raccogliere dati sulla concentrazione della soluzione per studi sulla legge di Beer o per monitorare le velocità di reazione.
Raccogliere uno spettro a lunghezza d'onda completa per misurare l'assorbanza, la trasmittanza percentuale, la fluorescenza (a 405 nm o 500 nm di eccitazione) o le emissioni.
Condurre esperimenti di cinetica enzimatica.
Effettuare studi sull'equilibrio di assorbanza vs tempo o assorbanza vs concentrazione.
Effettuare biotest colorimetrici o fluorescenti.
Utilizzate lo spettrofotometro a fibra ottica (VSP-FIBER) per misurare le emissioni provenienti da prove alla fiamma o da altre sorgenti luminose. Per un'analisi più dettagliata delle emissioni, prendete in considerazione lo spettrometro Vernier Emissions (VSP-EM).

The BioChamber 2000 is a 2000 mL plastic chamber that can be used with a CO2 Gas Sensor and an O2 Gas Sensor to monitor gaseous carbon dioxide and oxygen levels simultaneously in a closed system. The BioChamber 2000 is particularly useful when monitoring respiration and photosynthesis. The large side opening provides easy access to insert, adjust, or remove the sample.The BioChamber 2000 has two sensor ports on adjacent sides. Placing one of these ports on top, as shown, allows the O2 Gas Sensor to be in its proper vertical orientation. The CO2 Gas Sensor can then be placed in the other port on the side. Note that the two sensor ports are not equally spaced. One port is centered on its side of the chamber while the other is off-center. This was done intentionally to provide two options for your sensor orientation.If you choose not to use both ports, a size 6 rubber stopper fits snugly in the grommet. Note: While the stopper fits well, it is not guaranteed to be a water tight seal.
The Combination Dynamics Track and Optical Bench is aluminum and includes a metric scale. Extremely rigid, this 1.2 meter track will not sag under use. The track includes 2 Adjustable Two Foot Levelers.

With ultra-safe, patent-pending design, this spectrum tube power supply will provide a simple means of viewing gas discharge spectral lines with any of our spectrometers. Unlike other designs, this system has no exposed high voltage.
The gas tubes are permanently enclosed in plastic carriers that protect the tubes from breakage. There are no through-the-glass electrodes, so the tubes last far longer than older designs. The Power Supply will energize one tube at a time, and includes storage space for an additional six tubes.
A Spectrum Tube Fiber Optic Holder is included to hold an optical fiber cable in position.
