Bio-Rad Gradient 96 Well DNA Engine Thermal Cycler Model: ALS1296G /PTC0200**Unit has been tested to specifications. Has slight cosmetic blemishes from normal use. See photos for further detailsAlpha Units Single-Block Model:96V Alpha unit: Holds 96 x 0.2 ml tubes or one 96-well microplate. The Biorad Gradient 96-Well DNA engine Thermal cycler utilizes interchangeable sample blocks and heat pump assemblies, which allow the user to change format easily between runs while retaining NIST-traceable accuracy. This thermal cyclers precise peltier effect heat pumps deliver a full temperature range of 0 to 100'C electronically. This compact instrument offers speedy ramping rates of up to 3.0/sec. in models that hold 0.2ml. tubes or V-well plates. The DNA engine thermal cycler has unparalleled temperature homogeneity of +-0.4'C within 30 seconds of arrival at 60 Deg. C for all standard models. This Bio-Rad machine offers a large memory and amiable software that allows control over virtually every thermal parameter.SpecificationsThermal range5 to 105C, but no more than 30C below ambient temperature (4 to 100C for the Slide Chambers Alpha unit)Thermal accuracy0.3C of programmed target at 90C, NIST-traceableThermal uniformity0.4C well-to-well within 30 seconds of arrival at 90C (for most Alpha units; see specifications for individual Alpha units)Ramping speedUp to 3C/sec for all single- and dual-block Alpha units;Up to 1.2C/sec for the Slide Chambers Alpha unit.Line voltageDNA Engine cycler: 100240 VAC rms (no adjustment needed among voltages within these ranges)Frequency5060 Hz single phasePowerDNA Engine cycler: 850 W maximumFusesTwo 6.3 A, 250 V, 5 x 20 mmDisplaysOne 20 x 4 LCD alphanumeric displayPortsOne 25-pin 8-bit parallel interface printer portOne 9-pin RS-232 serial port for printer or remote useOne IEEE-488 bidirectional general purpose interface busMemory400 typical programs in up to 12 individual foldersAccuracy+0.3C of programmed target at end columns, 30 seconds after the timer starts for the gradient step, NIST traceableColumn uniformity+0.4C, welltowell within column, within 30 seconds of reaching target temperatureGradient calculator accuracy+0.4C of actual well temperatureLowest programmable temp30CHighest programmable temp105CAdditional Prep Fees May Apply
