DPTC Lab Equipment and Photos


DPTC Lab EquipmentExperion Automated Electrophoresis Station
Performs all of the steps of gel-based electrophoresis in one compact, durable unit. It automates analysis by combining electrophoresis, staining, destaining, band detection, and imaging into a single, 30 minute step. It's an electrophoresis cell, power supply, and imager built into a single device.


DPTC Lab EquipmentLaser Tweezers
Also known as optical tweezers, they use a strongly focused laser beam to trap smallparticles and objects within the beam. The laser tweezers can manipulate individualcells and similarly sized bits of matter and measure the forces involved with great precision. Measuring the interactions of the particles accurately is important toassess their function.
