These unbreakable all-in-one pipets eliminate the hazard of broken glass and exposure to infectious materials as well as put an end to matching rubber bulbs with glass pipets. Molded from see-through low density polyethylene, these transfer pipets are inert to biological fluids and most acids, temperature resistant down to -196 °C and the low-affinity surface reduces sample loss.

  • ventilation ribs minimize condensation

  • guaranteed sterile via gamma irradiation

  • disposable

Petri dishes are easy to handle. A perfect fit lid enables it to be removed and replaced quickly with one hand. The precision flat bottom, insures that a minimum amount of culture media will provide even distribution over the bottom of the plate, minimizing and controlling medium consumption.

Precision & Convenience

  • molding process produces optimum product clarity and the most consistently flat dish in the market

  • ideally suited for all automated filling and streaking equipment

  • can be traced for quality assurance and sterility verification

  • side arrows and Isomarks available

  • comprehensive line of standard, shallow deep and media saver dishes

  • Pressure-sensitive counting
  • Average count facility
  • Bright white energy saving LED lighting
  • With BioCote antimicrobial protection
  • Audible confirmation
  • Choice of light or dark background
  • Connectivity to printer or computer

Touch pressure with felt tip marker on petri dish registers cumulative count on the digital display with confirmation by audible tone (can be turned on or off). The pressure required to register a count can be adjusted to suit each user. Averaging facility calculates average count over multiple plates. Counting results as well as useful statistics including SD can be sent directly to the accessory printer or to a computer via a USB cable supplied.

Sub-stage illumination by low energy bright LED's allows glare-free optimum viewing. A switchable black background is provided to enhance viewing of translucent and difficult to see colonies. Supplied with a Wolffhuegel graticule, segmentation dish and dish centering adapters to facilitate use with 50mm to 90mm dishes. A choice of magnifiers and a printer are available as optional accessories.

Stickers for labeling petri dishes.

PetriStickers allow for petri dishes to be labeled quickly, neatly and reliably. Made with water-resistant ink, substrate and adhesives and will remain firmly attached at temperatures from 42° to 4°C. Simply remove the label's protective backing and apply it to the back of a petri dish. After labeling, the dish can be held in a comfortable position for streaking or colony transfer, stored in an incubator or refrigerator, and photographed.

Lazy-L-Spreaders disposable microbiological spreaders provide an economical alternative to bending glass rods or pipets for spreading samples on agar surfaces and filters in Petri dishes. They are supplied sterile-no need to flame sterilize or autoclave.

  • Unlike glass spreaders, durable polystyrene Lazy-L Spreaders are non-breakable and pose no safety hazard
  • L-shaped for convenient "lazy" spreading; just turn the Petri dish for smooth, even sample distribution
  • Smooth spreading surface and a slight upward turn reduce the chance that the spreader will dig into agar
  • Packaged in pre-sterilized pouches of one or 10 each
  • Pre-sterilization eliminates flaming or autoclaving and reduces risk of contamination
  • No more time spent bending glass rods or waiting for glass or metal spreaders to cool before use!
  • Manufactured by Excel Scientific

Our Inoculating Loops and Needles are smooth and flexible to facilitate uniform, smooth streaking without damage to media/gel surfaces. The needles are straight and suitable for removal of single colony specimens. The loops are extra-smooth and constructed of polypropylene and rubber. Both the loops and needles are packed sterile in safe, tamper-proof, zip-seal resealable bags. Cross contamination due to improper sterilization is eliminated. They can be used under hoods without danger, are color coded for ease of size identification, and are extra long to reduce the risk of contamination. Certificate of conformity is available upon request.
