Power Source. Can be used with 75V or 150V. Maximum current is 250 milliamps. Can be
used with one or two cells simultaneously. Run time for gels at 75V is 40-50 minutes and
20-30 minutes for 150V. 8" x 6-1⁄2" x 8".
SB49189M - $178.50
Glass Slides. Pack of six.
SB49191M - $17.85
Casting Tray. With embossing gel ruler and two rubber end caps.
SB49194M 7 cm x 7 cm - $30.95
SB49193M 7 cm x 14 cm - $35.15
Agarose. Prepare your own Agarose gels at any concentration with the
addition of TBE running buffer. Can be stored at room temperature for years. 5
grams low EEO.
SB49019M - $14.90
DNA Stain. Stain and de-stain in 40 minutes. The highly sensitive
stain will stain a gel in about 20 minutes and de-stain in
20 minutes. Once the gels are stained they can be stored for
months without fading. Stain up to 20 gels with 60 ml of 20X
concentrate.
SB49020M - $11.85

Walter Electrophoresis Stations
Designed with safety and convenience in mind. The injectionmolded
UV transparent chamber is made from thick acrylic,
making it durable and leak-proof while the lid fits securely in place and can
easily be removed. Units feature adjustable leveling feet, recessed electrical wires,
and a safety stop that prevents the gel from running when the cover is not securely
fitted. Each casting tray with embossed gel ruler has rubber end caps and multiple
slots for easy and versatile comb placement. Grades 9-college.
Dual Station. Supports up to 16 students. Each set includes two electrophoresis
apparatus, one power supply, and two adjustable volume pipettors (5-50 µL). The
EL-100 model (SB49195M) includes two 7 cm x 14 cm casting trays, while EL-200
(SB49196M) includes four 7 cm x 7 cm casting trays.
SB49185M EL-100 Dual Station - $821.10
SB49187M EL-200 Dual Station - $827.05
Four Station. Supports up to 32 students. Each set includes four electrophoresis
apparatus, two power supplies, and four adjustable volume pipettors (5-50 µL). The
EL-100 model (SB49195M) includes four 7 cm x 14 cm casting trays, while EL-200
(SB49196M) includes eight 7 cm x 7 cm casting trays.

Walter Electrophoresis Unit
This electrophoresis apparatus includes an injection-molded UV transparent base and a
transparent cover. Casting trays have an embossed gel ruler and rubber end caps. Allows six
7 cm x 7 cm
electrophoresis gel trays to run simultaneously on one apparatus, six 6-toothed combs, and
six 7 cm x 7 cm casting trays. Unit measures 16" x 12-1⁄2" x 7". Grades 9-college.
SB49197M - $330.85
An Introduction to Electrophoresis
Economical two-part exercise provides an introduction
to agarose gel electrophoresis and is designed for eight
groups of students in two 40-60 minute lab periods.
Includes four colorful dye mixtures and DNA. In the first
part of the exercise, students identify unknown dye molecules
by comparing their electrophoretic migration with
the migration of known dyes. In the second part, students
identify dye molecules that bind to DNA and determine
the mechanism. Includes complete instructions, samples 1-4, DNA, eight transfer pipets
(one ml each), agarose (5 grams), and TG buffer (contents makes 3.5 liters of re-usable
buffer). Grades 9-college.
SB49181M - $47.55

adjustable volume pipettor, and the Introduction to Electrophoresis experiment kit
(see SB49181M at left for complete description).
