For several years, our customers, impressed by the excellent optics and great price of our SMT1 Dissecting Stereomicroscopes, have been asking for a Fluorescence Dissecting Scope in the same vein of quality and economy. After lots of research and development, recently presented at the International C. elegans Meeting, and the result is the SMT1-FL.

The Tritech Research Fluorescence Dissecting Stereo-microscope replaces the old cumbersome mercury arc lamp with a state-of-the-art Light Emitting Diode (LED) illuminator. This dramatically lowers power consumption, heat, and the cost of accessory optics and power supplies.

For example:

Fluorescence Illumination	Mercury Arc Lamp	Tritech LED System
Watts consumed	200	4
Lifespan (hours)	250	10000
Cost per bulb (US$)	$250	$25
Bulb Cost / 10000 hrs	$10,000	$25
Power cost @ $.2 / kW-hr	$500	$1
Total Cost of disposables	$10,500	$26
Cost of Scope + Acces.	$18,000	$6,795
Total Cost	$28,500	$7,021

Advantages	1 lamp for fluorophores	low heat output
		energy efficient
		40x lifespan
		dichroic mirror optional
		1/400 bulb cost
		1/500 power usage
		no UV danger
		no high-voltage danger
		no toxic Hg concerns
		less expensive housing

Our system uses ultra-high-quality multi-coated filters to isolate the excitation and emission wavelenghts from each other by up to 4 orders of magnitude, keeping bleed-through background at a minimum.

The nematode C. elegans expressing the [Punc-25::GFP] transgene (juIs76). unc-25 encodes glutamic acid decarboxylase (GAD). UNC-25 is expressed specifically in GABAergic neurons and localizes to cell bodies, axonal branches, and synaptic regions in the 19 type D motor-neurons, most notably shown here in the 13 ventral nerve cord neurons.

"Tritech Research is the first and only company to offer LED-based complete GFP Dissecting Stereo-microscope Systems, saving customers thousands of dollars. Traditional Mercury arc lamp based fluorescent systems cost up to $35000. They have perfected the LED-based GFP microscopy and completely eliminated the mercury arc lamp and associated optics, bringing the price of the microscope to one third of its previous cost!."

Complete Injection Scope Systems

microINJECTOR™ System Complete w/ Inverted Microscope, manipulator - Inquire

MINJ-1000: $11,891.89 † - Special Order

Tritech Research sells complete microinjection systems that integrate our famous microINJECTOR™, Pulse Length Control Module (PCM), and needle holder with top name brand inverted microscopes and micromanipulation equipment. We take advantage of our status as a fully authorized Narishige dealer and manufacturer of custom OEM solutions for Olympus and other microscope systems to get you great prices and the added convenience of receiving a fully integrated microinjection system from a single source.

Other features include our custom GlideStage®, which provides a fine level of manual stage manipulation at a fraction of the cost of motorized stage manipulators. When the stage is in use, you can employ a low-cost mechanical joystick-type micromanipulator, to save thousands of dollars over other systems.

Microscope Features:

Small Foot Print.
Excellent Quality Optics.
Includes our custom-made Hoffman Modulation Contrast (HMC) optics for DIC-like images at a significantly reduced price.
Trinocular head for photo and video documentation.
Available with a fluorescent system for detection of GFP, DAPI, Rhodamine, etc.

Some researchers are curious whether a low-cost dedicated injection station like the MINJ-1000 is going to be a compromise in terms of quality, ease-of-use, or optics. The answer is - no. Great optics are as important to us as they are to you. Just as there can be a "good" DIC image, when the right Wallaston prism is combined with the right numerical aperture objective and the correct polarization, and a poor DIC image when these items are not optimized, we design and choose our HMC optics to work together to get you great images. Don't let a bad experience with a local microscope rep who doesn't know what he is doing, or understand how to optimize a system for your microinjection needs prejudice you.

Here are links to some QuickTime movies showing oocytes and the syncitial gonads of some C. elegans worms under our MINJ-1000 scope. We think you will be impressed with how clear and easy to inject these structures are. Click on these links to watch the QuickTime Movies (it will take a while for them to load completely, and then they will play.)

Drosophila Anesthesia CO₂ station

MINJ-DROS-1: $459.46 † - In Stock

Image for Drosophila CO[2] Workstation coming soon!

The Drosophila CO2 Work Station allows flies to be anaesthetized with unparalleled precision, convenience, and safety. An electronic foot pedal allows the user to deliver just the right amount of CO2 to keep flies asleep. This saves a lot of CO2, compared with continuous-flow systems, is much less likely to inadvertently kill important specimens due to over-anaesthetizing, is much more convenient than systems that require users to reach around and hand-operate valves in the middle of genetics, and is safer, for all concerned, than using organic solvents as anaesthetics.
