Smart Pack

Smart Pack Goals

  • Reduce Weight of Packaging
  • Increase Usage of Recyclable Materials
  • Improve Packing Integrity
  • Decrease Shipping Costs

Thorlabs' Smart Pack Initiative is aimed at minimizing waste while providing adequate protection for our products. By eliminating any unnecessary packaging, implementing design changes, and utilizing eco-friendly materials, this initiative seeks to reduce the environmental impact of our product packaging. 

The updated B2939 packaging primarily consists of recycled paper and cardboard and weighs 23% less than the original packaging. This weight change results in a 70.86 kg reduction in travel-based CO2 emissions per year, based on typical product sales.

As we move through our product line, we will indicate re-engineered, eco-friendly packaging with our Smart Pack logo, which can be seen above.

Does Thorlabs sell just the dropper bottles? I do not need the wash bottles.

Thank you for contacting Thorlabs. Custom or component level parts can be requested by contacting your local Thorlabs distributor (in your case Laser 21 Pte Ltd. P: +(65) 6565 1221 / E: sales@laser-21.com). We will discuss the pricing and lead time directly.

Please bring back the small (30mL?) glass dropper bottles for solvents sold apart from the large squirt bottles. Thank you!

Thank you for your feedback. The glass dropper bottle was superseded because its rubber dropper portion would deteriorate within 1-2 years and contaminate the solvent inside the bottle. We moved to these plastic dropper bottles that are made from non-reactive plastic instead to avoid this contamination. While we are not planning on bringing the glass bottle back at this time, we may be able to offer a special offering of it. Please email techsupport@thorlabs.com if you would prefer this option, though keep in mind the potential contamination.

I have the same issue as Makarov. Our BD8 dispenser bottle refuses to fountain (even when sitting on a flat surface). It seemed to work initially, but stopped soon after purchase in May 2013 (maybe because the level dropped below the half way mark, as Makarov observed).

Response from Jeremy at Thorlabs: Since you did not leave your contact information, can you contact our RMA department please? We can arrange to have a new one sent to you.

We can't get the bottle to work unless it's full. When it's filled under 1/2, no amount of pressing or shaking gets ethanol fountaining. The pump does not work. Is there any trick we're missing?

Response from Chris at Thorlabs: Thank you for using our feedback tool. The bottle should sit on a flat surface. You should not need to pick up, shake or squeeze the bottle. If you open the lid and push down on the top, suction will draw fluid up and create a small pool in the reservoir. If you turn the bottle sideways, it cannot work when the level is below halfway since the liquid will not make it to the end of the hose inside.

A response from Ken at Thorlabls to d.sarkar: We do not sell any chemicals. We only sell the empty bottles used to store them.

  • Pure Cotton, Non-Woven, Low Lint, Absorbent

The Handi-Pads are plush non-woven cotton pads.

These pads are free from contaminants and adhesives, which make them ideal for use with optics cleaning solvents. The large plush pad allows the user to make a single continuous wipe across the entire surface of the optic being cleaned, even if the surface is curved such as with a lens. The pad can also be used to wrap optics before placing them in a storage container.

  • Ideal for Cleaning Connectors between Polishing Steps

Cotton-Tipped Applicators (Item # CTA10)

  • 6" Wood Stick Disposable Applicators with Cotton Tips (100 per Pack)
  • Appropriate for Cleaning Connectors or Optics

Kimwipes® are durable, low-lint sheets and the cotton-tipped applicators are nonabrasive, disposable swabs. Both the Kimwipes and the cotton-tipped applicators are appropriate for cleaning optical fiber connectors. Additionally, the cotton-tipped applicators are optical grade, meaning they are nonabrasive and will not deposit contaminants, making them appropriate for cleaning optics (see our Optics Handling and Care Tutorial for details).

Please note that Kimwipes are sold in cases, with 12 boxes per case and 280 Kimwipes per box, and are not ideal for cleaning optics. Instead, we recommend using the MC-5 lens tissues to clean optics. We do not recommend using the cotton-tipped applicators with acetone.

Dusters with Low Global Warming Potential

  • Non-Flammable HFO-1234ze Propellant
  • Integrated Plastic Nozzle
  • Low Global Warming Potential (GWP) of 6
  • Zero Ozone Depletion Potential

Thorlabs offers the CA4-US and CA6-EU Eco-Friendly Air Dusters. These dusters evaporate HFO-1234ze to create high pressure gusts. These general use dusting cans are ideal for cleaning and maintaining optical and electrical equipment while leaving no residue. Due to different nations' regulations, we offer two versions of this product: the CA4-US is compliant in the United States and Canada, while the CA6-EU is compliant in the European Union. These dusters are chemically identical, but have different packaging and volumes; the -US version contains 10 ounces, while the -EU version contains 400 mL. Be sure to check with your government's regulations before ordering either product. The labels for the CA4-US can be downloaded by clicking here and the CA6-EU by clicking here.

Global Warming Potential (GWP)
Global Warming Potential according to the United States Environmental Protection Agency is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given time, relative to the emissions of 1 ton of carbon dioxide (CO2). CO2 is defined as having a GWP of 1. GWP is usually estimated for a 100-year time horizon, but other methods may be used. The higher the GWP of a gas, the more energy it can trap in Earth's atmosphere, correlating to a higher average global temperature. For a point of comparison, methane (CH4) is listed as having a GWP of between 21 and 25. This duster's propellant, HFO-1234ze (1,3,3,3-tetrafluoropropene), is phototransformed in the air with ~100% degradation observed by 14 days, and has a GWP of 6.
