WILOVERT

INVERTED
MICROSCOPES

have gradually become
an indispensable tool in many laboratories where living material is examined.
Also, they are being increasingly upgraded into highly specialized systems
for certain routine applications and particular research developments. The
new Wilovert microscopes are especially designed
for this trend, featuring:

HIGH
STABILITY AND ERGONOMY

The
entire U-shaped body of the Wilovert consists of
one cast part, which provides optimal conditions for high stability.
Micromanipulators can easily be adapted to any microscope in the Wilovert series.

WIDE
CHOICE OF LIGHT SOURCES

Besides
the 6V / 20W and the 6V / 30 W halogen lamps there is also a choice of 12V /
50W or 12V/100W lamps which can also be adapted from the outside. For
fluorescence work we offer HBO 50W or HBO 100W mercury lamps.

OPTICS

Objectives

As
inverted microscope specimens are examined in tissue culture vessels of
different heights, base thicknesses and materials, as opposed to the standard
specimen slides and coverglasses used for upright
microscopes, special optics are required. Hund
offers objectives and matching condensers with long free working distances.

CONDENSERS

There
are the following condensers to choose from:

•
Condenser NA 0.25 for transmitted light brightfield
with 58 mm free working distance.

•
Combined condenser NA 0.25 with 58 mm free working distance for transmitted
light brightfield and phase contrast.

•
Condenser NA 0.4 for transmitted light brightfield
with 55 mm free working distance.

•
Combined condenser NA 0.4 with 38 mm free working distance for transmitted
light brightfield and phase contrast.

HOLDERS
FOR CULTURE VESSELS

Frequently
used culture vessels such as petri dishes, tissue
culture vessels, microtest trays and microtiter trays are inserted in special holding frames
on Wilovert microscopes. The object guide ensures
that specimens are completely scanned.

WILOVERT
AS HF

The
standard outfit for routine examinations of transparent specimens with richly
contrasting details which can be done in brightfield.
The advantage of this outfit is the simple, clearly arranged configuration
which leaves the user plenty of room for manoevre.

optics as Wilovert SE HF, but with objectives A Ph
10x, SPL Ph 20/0.35 with combined condenser NA 0.25

(brightfield and phase contrast)
and focusing telescope.

WILOVERT
S HF-LL

Outfit
for scientific work and highly qualified routine examinations in brightfield.

ACCESSORIES

Micromanipulators
and microinjectors

Micromanipulators
and microinjection systems are now commercially available for working on
living cells – e.g. for injecting substances into cell nuclei or
cytoplasm. The stage of Wilovert microscopes proves
ideal for work with these accessories. Due to the importance of being
vibration-free for microinjection and electrophysiological tests, it is fixed
on both sides of the microscope stand. As focusing is performed by sliding
the objective nosepiece not by raising or lowering the stage, the system
stage-specimen- micromanipulator (microinjector)
always maintains a constantly high level of stability.

UPGRADE
OPTIONS

IMAGE
DOCUMENTATION

The
following accessories can be used for documenting microscope images:

–
Photographic systems

–
Video systems

–
Image archiving

There
is a choice of two different binocular phototubes for adapting the
documentary equipment via standard components.

BINOCULAR
PHOTOTUBES

Binocular
phototube 70/30

70%
of the light is directed to the photographic or video

camera, 30%
to the eyepieces for simultaneous viewing.

Binocular
phototube 100/100

The
light can either be fully directed to the eyepieces or to the connected
documentary equipment. This is a particular advantage for dark images as the
full light intensity is available.

Video
cameras are connected via C-mount adapter.
