I picked up two ABI PRISM 377 DNA sequencers. These are the last generation of slab gel sequencers.

With the front open, you can see the place where the gel gets mounted.<\/p>\n

The left side opens, and the bottom cover comes off. The laser can be seen at the bottom, and some of the power supplies on the left.<\/p>\n

\"Open<\/a><\/p>\n

Here is the laser, a Uniphase Argon laser, 0.5W 2214-40MLA 1998.<\/p>\n

The power supply modules are located on the left side. On the top left is the laser power supply. The electrophoresis power supply is on the left in the middle. To the right of it is the power distribution center–plugs for the laser and electrophoresis power supplies, and the blower motor. On the bottom at the left is the blower motor. In the middle at the bottom the top of a mirror module that bounces the laser back to the right at the level of the bottom of the gel. On the right at the bottom, the servo motor that moves the detector unit along the bottom of the gel.<\/p>\n

Here’s the laser power supply. The laser is not plugged in.

The power distribution center labels: J41 DC Power Supply Max 4000W J40 Heater and Pump Control<\/p>\n

The electrophoresis power supply: Spellman P\/N X2094 Rev. E4 Model No PTV5P300X2094
\n230V 5A, output 0-5kV, 0-60mA.<\/p>\n

Two interesting chips on the board, a FPGA and a pair of voltage converters.<\/p>\n
