Scientist Profile: Dr. Iva Greenwald

Dr. Greenwald's lab studies how cell-cell signaling can specify cell fate during development.  They utilize the differentiation of pluripotent C. elegans vulval precursor cells (VPCs) to specific cell fates as a model.  This rich system includes LIN-12/Notch, a receptor tyrosine kinase (RTK) / Ras / mitogen-activated protein (MAP) kinase cascade, its proteolytic cleavage by a Delta / Serrate / LAG-2 ligand, wnt signaling, and microRNA-mediated gene regulation.  [More...]

DigiTherm ® Incubators and Temperature Controllers with many options and low prices!

Not only is Tritech Research a cool company, but all of our incubators have active cooling as well - making them true heating/cooling environmental chambers. Equipped with many options (even internet control and monitoring!), they can be adapted to any type of research.


They are ideal for bacteria, nematodes (C. elegans), insects (Drosophila), amphibians (Xenopus), fish (zebrafish) and plant cell culture (Arabidopsis). Your research deserves the best incubator, and now you can afford more than one, making it easy to run experiments at different temperatures simultaneously. Whether you are interested in activity monitors, circadian options, customized ports, CO2 control, or built-in cameras, we have all that and more!


We have a convenient, quiet, energy-efficient incubators with heating/cooling temperature control, which is great for maintaining fly stocks, or growing S2 cells. General Activity Monitoring provides an important control for any study in behavioral genetics. Therefore, we can provide built-in interior jacks that can accommodate up to 20 TriKinetics Activity Monitors. See details about the drosophila incubator.


Our CO2 Incubators are microprocessor controlled, solid-state heating/cooling with a NDIR CO2 sensor. They are ideal for mammalian and insect cell culture. At this price, you can keep your lab happy by having more than one incubator, eliminating the risk of spreading contamination between experiments.See details about the CO2 Incubator


For Vaccine Development research, we developed the DigiTherm® Unibator™ and DigiTherm® HexaBator™. Conveniently programmable, these incubators have the ability to switch to refrigeration mode and rapidly cool samples to stop biological and chemical reactions at preset times or by remote control over the internet! See details of the Unibator

Our microinjection line: microINJECTOR™ and more

Looking for the mythical microinjector that suits your needs and is reasonably priced? Well, this hybrid actually exists! Whether you’re searching for analog, digital, pressure-type, or positive displacement syringe pumps, we offer a wide variety of microinjection options. Browse through our catalogue and let us know if there are any modifications you are interested in. We can make it happen!

We have developed our own microinjectors: the analog MINJ-1, the digital MINJ-D, the high speed pneumatic MINJ-FLY, as well as the positive displacement microinjector MINJ-PD used for injecting stem cells into the brain, spinal cord, and embryos. They cost only a fraction of competing systems and allow you to control both the pressure and the duration of the microinjection pulse with exacting precision, or the actual volume in the case of the positive-displacement-type injector.

Our complete microinjection systems integrate our industry-standard microINJECTOR™ control system 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 getting a fully integrated microinjection system from a single source.

Microscopes: Get 3 for 1 ?!!!

Our dissecting stereomicroscopes have optics that rival the best in the world, at less than 1/3 the price! This includes a fluorescence version. We also have economical inverted and upright compound microscopes.

We are proud to offer fantastic microscope solutions for thousands of dollars less than any competing system without making any compromise on quality or optics. At our incredible price, order three for the price of one of our competitors' scopes. Lower prices for the same superior optics! We also offer stage temperature controllers for heating and cooling.More Details about our Microscopes

PourBoy® 4: Get excited pouring Petri plates

Upon repeated demands from researchers, we developed an inexpensive, efficient, and reliable media dispenser, the PourBoy. We also have the low est prices on Petri Dishes.

Most devices on the market are either expensive, unreliable peristaltic pumps, or expensive unreliable motor-driven, syringe-based pumps... Finally there is something better and less expensive! (click for details of the PB4). We also have 35mm, 60mm, 100mm, and 150mm sterile Petri plates. We offer the same low prices whether you're at a small institution or a giant one. (see our prices and size options)

Electroporation: Clone it!

Our Cloning Gun® electroporators are the only cordless, rechargeable, and hand-held electroporators available, providing you several years of innovation and development in one compact, small device.

Our BactoZapper® Cloning Gun® can achieve transformation efficiencies (TE) of over 1010 transformants per µg of input DNA with E. coli bacteria harvested in stationary phase, and the MammoZapper® version achieves TEs exceeding 50% of viable cells with a variety of standard mammalian cell lines and has successfully transfected neurons, astrocytes, neuroglia, lymphocytes, monocytes, fibroblasts, epithelial and endothelial cells.
