PR1MA™ Touch Power Supply
- Touch screen control
- Bright color display
- Dual orientation, auto-rotating display
The PR1MA™ Touch is a workhorse electrophoresis power supply, ideal for the efficient separation of nucleic acids and proteins as well as basic western blotting applications. Four pairs of output jacks are wired in parallel for connecting multiple electrophoresis tanks. A color touch screen allows quick setting and monitoring of all run conditions, including run time, voltage, and current. Users can select “Constant Current” or “Constant Voltage” during an electrophoresis run, keeping the chosen parameter fixed as resistance changes. The dual orientation design with a rotating display allows the PR1MA™ Touch to be installed in the most convenient location, on a shelf or bench, saving valuable space.
The PR1MA™ Touch features a logical user interface.
Setting up an electrophoresis run couldn’t be easier; simply touch the parameter to select it, press the “up” and “down” arrows to adjust the value, and then touch “Start”. All parameters are always displayed, with no need to toggle between Time, Voltage, or Amperage. In addition, the run status is always displayed.

PetriStickers™ Petri Dish Labels
Quick, clean, and reliable labeling for petri dishes.
PetriStickers™ provide a fast, neat, and dependable way to label petri dishes in laboratory environments. Designed for ease of use, these stickers apply directly to the back of the petri dish, keeping labeling information visible without interfering with sample handling, streaking, or observation.
Each sticker is made with waterresistant ink, durable substrate materials, and strong adhesives that remain securely attached across a wide temperature range, from 42ºC down to 4ºC. Once applied, plates can be comfortably held for streaking or colony transfer, safely stored in incubators or refrigerators, and easily photographed for documentation.
Ideal for microbiology, research, teaching labs, and quality control environments, PetriStickers™ help streamline workflow while maintaining clean, professional labeling.
Main Attributes
- Quick and neat labeling for petri dishes
- Waterresistant ink, substrate, and adhesive
- Secure adhesion from 42°C to 4°C

General Purpose Solid Door Manual Defrost Freezer
The Standard Manual Defrost Freezers are intended for general
purpose applications where precise temperature control and maintenance are not
essential and there are no requirements for temperature alarms. Manual defrost
units have been designed to operate without product damaging auto defrost
cycles.
The NSPF units have natural
refrigerants. The Hydrocarbon Manual
Defrost Freezers take a large step forward in performance from past solid door
general purpose units; offering a digital temperature display and alarm module
coupled with a microprocessor temperature controller.
Defrosting
of the unit will need to be performed periodically to prevent severe ice
build-up.
Corepoint is Going Green! We are an industry leader in providing a
variety of Refrigerators and Freezers that are built with Hydrocarbon
Refrigerants, R290 or R600a.
Environmentally friendly, natural hydrocarbon (HC) refrigerants (not
containing hydrofluorocarbons) vastly reduce global-warming potential (GWP)
while meeting new EPA/SNAP mandates and UL, ASHRAE compliance guidelines.
Periodic manual defrost is required on these
units.
