The last offering from MJ Research is the PTC-200 DNA Engine. The sleek design and rugged chassis are suggestive of an Italian sports car. Interchangeable sample blocks and heat pump assemblies allow the user to change format easily between runs while retaining NIST-traceable accuracy. The lab need only buy the single control unit and supplement it with the desired Alpha modules- such as dual- independently controlled blocks- microplate format- or a slide adapter for up to 16 slides. Thermal control is achieved by either block- in-sample probe- or calculated methods. Heating rates up to 3C/second reduce reaction times while 0.4C temperature homogeneity can be reached within 30 seconds at 90C. The Hot Bonnet heated lid controls pressure and height to accommodate various plasticwares. A Power Bonnet is available for robotic systems. Additionally- a single cycler can be networked to control up to 15 separate instruments. A PC can also control and monitor cyclers remotely and export data to video screens or databases in real time.
The MJ Research PTC-200 is a 96 well gradient thermocycler that can be supplied with different alpha blocks such as a 96 well or a dual 48-well block. The dual 48-well block allows two independent programs to be run at the same time. The PTC-200 also uses the Hot Bonnet to allow oil-free operation. Precise Peltier-effect heat pumps -robustly designed for repeated cycling-- deliver the full temperature range of 0-100C electronically- in a compact instrument with a footprint that measures 24cm x 28cm x 27cm high. Speedy ramping rates of up to 3.0/sec in models that hold 0.2ml tubes or V-well plates; Unparalleled temperature homogeneity: + or - 0.4C within 30 seconds of arrival @ 60C for all standard models. Large memory and amiable software that allows control over virtually every thermal parameter. Cycler has 80-character LCD/ menu-driven software- and 200-program memory with individually secured directories.
