Get micro-organised with essential consumables from Lasec

We all know that sometimes, effectively managing your laboratory supplies can be quite challenging. Laboratory managers spend lots of time evaluating stock levels, expiry dates, pack sizes, pricing, quality, lead times and suitability before making purchasing decisions. All this is done with the goal of streamlining processes while reducing costs.

At Lasec®, we recognise the importance of efficiently managing the inventory of commonly used consumables within a microbiology lab.

While this short article may not address all the specific challenges encountered in your lab, we hope to provide some insights on maximising purchasing plans for three main categories of essential consumables, namely growth media, Petrifilm™ and consumable labware.

Essential consumables for microbiology:

Neogen Culture Media

Neogen Culture Media (NCM) are ISO and UKAS certified producers of high-quality dehydrated culture media and supplements. NCM currently produces over 315 dehydrated culture media products which include pre-enrichments, selective, differential and chromogenic media.

  • Culture media products are available in standard and bulk packs to suit your lab’s unique demands. Take the opportunity to get a little “more bang for your buck” by purchasing the bigger pack sizes i.e. 5kg, 10kg and 25kg.
  • NCM also produces “convenient formats” which include pre-poured media plates, EZ Prep pouched media and µPREP bagged media. These pre-measured and pre-sterilised formats will prove to be very handy when the media preparation steps are delaying turn-around time for tests that need to be completed and reported on quickly.
  • As an authorised distributor of Neogen Culture Media, Lasec® supplies our products into various market segments which include the Food & Beverage, Water and Pharmaceutical industries, as well as the Clinical market. Due to NCM having dual manufacturing sites in the UK and USA, we offer faster lead times for commonly used media.  For specialised media types, talk to us about a standing order to ensure efficient and cost-effective supply.

3MTM PetrifilmTM

Lasec®, distributors of 3MTM Food Safety products, is the proud supplier of PetrifilmTM, a simple and trusted method for culturing and enumerating microorganisms. This technology was initially introduced during the mid-80’s and has revolutionised the way food safety professionals test for indicator organisms. Designed and manufactured according to ISO 9001, PetrifilmTM has earned international recognition with certifications from both AFNOR and AOAC.


Try PetrifilmTM as a solution in your micro lab

The great thing about PetrifilmTM plates is the fact that they are ready-to-use. No weighing, mixing or autoclaving is required - simply inoculate, incubate and interpret your results. Up to 20 of these plates can be stacked in the incubator, saving space and electricity. An unopened box has an impressive shelf life of 18 months while the internal packs can be used for up to 30 days after being opened.

We offer a variety of plates with formulations for aerobic counts, Enterobacteriaceae, coliforms, E. coli, yeast/mould, S. aureus, environmental Listeria and lactic acid bacteria. These can be used for several purposes which include food product, ingredient and environmental testing. PetrifilmTM also has the added bonus of being able to double as a contact, and even as an air sampling plate. – Talk about an over achiever!

Plasticware and Glassware
The below table briefly describes some of the microbiology labware essentials recommended and supplied by Lasec:

Consumable

Our offer

Petri dishes

Petri dishes are a staple for every microbiology lab preparing their own culture media. Our buying power and access to various suppliers allows Lasec® to find the right price/quality ratio to meet specific lab requirements.

Inoculation loops and spreaders

For a winning streak, we supply both metal and calibrated plastic inoculation loops for reusable and disposable purposes. Our plastic spreaders with L-shaped design ensure a smooth and evenly spread plate every time.

Syringe filters

For fast, low volume sterilisation, use 0.2μm syringe filters with either cellulose acetate or polyether sulfone membranes to effectively remove bacterial cells from the solution. With high flow rates and low protein binding, these syringe filters are suitable for sterile filtration of all culture media applications.

Weighing boats

If your current cracked weighing boat is causing you frustration during media preparation, consider our disposable weighing boats made from polypropylene that can withstand temperatures up to 70°C. The range consists of square shaped 7ml or 100ml, and diamond shaped, 5ml, 30ml or 100ml weighing boats.

Graduated beakers and cylinders

“You won't know what you have until it's measured” - Our Italian made standard clear, polypropylene (PP) beakers and cylinders with blue graduated markings are perfect for measuring out the volumes required for media preparation and sample dilution. For a more durable plastic, better suited to repeated autoclaving, ask about our clear, polymethylpentene (PMP) beakers with red graduated markings. If you are looking for volumetric glassware, we stock a variety of Erlenmeyer flasks, filtration funnels and measuring cylinders from our glass experts at Glassco.

Media and reagent bottles

Say goodbye to expansion cracks with Simax media bottles from Lasec®, made of borosilicate glass 3.3, offering excellent chemical resistance and thermal stability. The blue GL 45 screw cap and pouring ring are heat resistant up to 140°C. These are available as both clear and amber glass in a range of sizes.

Biohazard bags

Safely dispose of your biological waste with our steam autoclavable waste disposal bags available in red and clear, with “Biohazard” clearly indicated on the front. These bags can withstand temperatures up to 121°C.

Autoclave tape

"Has that been autoclaved yet?" Confidently answer the age-old question that haunts many microbiologists around the world with our lead-free steam sterilisation indicator tape that is available in various sizes and colours.

 

The products in the above three categories do not constitute an exhaustive list of the consumable microbiology products offered at Lasec®, however, we hope that it demonstrates the versatility and flexibility we can offer to help lab managers cut costs and maximise productivity in the lab.

Micro labs big and small, we’ve got a solution for them all!
