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
  • Applies to the back of petri dishes for unobstructed handling

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.
