LW Scientific i4 Infinity Instruction Manual

Maintenance
1
Always cover your microscope with the dust cover when not in use. When cleaning the lenses, use lens paper or a
cotton swab dipped in lens cleaning solution.
2
Excess oil should be cleaned off your 100x objective and stage at once. An alcohol pad is best for removing oil from
the stage and on the other metal parts, but is not recommended for use on the lenses. Use lens cleaning solution and
lens paper to clean off your objectives.
3
Dust in the nosepiece or ocular tubes should be blown out using filtered air. Canned air dusters work well for this job.
4
Whenever you remove an objective, we recommend that you place it back into the original plastic shipping vial until
ready to be placed back on the microscope. SCREW THE OBJECTIVE SECURELY INTO THE CAP OF THE HOLDER - DO NOT
DROP OBJECTIVE LOOSELY INTO CONTAINER.
5
To keep your microscope in top condition for years, LW Scientific recommends that you have the microscope
professionally serviced once a year.
Warning: The 40x objective is not sealed for oil immersion. Damage to the 40x objective due to oil
immersion is not covered under warranty.

Introduction
The LW Scientific I-4 microscope features exceptional optical quality with an infinity optical system, like found on the
most expensive laboratory microscopes, but at a fraction of the price. The ergonomic narrow design allows users to
rest their arms flat on the table and easily operate all controls. The binocular eyetubes can also be rotated upward to
achieve an additional 2 inches of height for taller users. LED lighting produces "daylight" color, with a cool temperature
and long life. Comfort, durability, dependability, and superior imaging make the I-4 a great value for labs, physicians,
vets, and universities. The I-4 microscope is intended for use as a biological microscope in a professional environment in
accordance with the guidelines set forth in this operations manual.
