To start a return, you can contact us at sales@cannabislabware.com. Please note that returns will need to be sent to the following address: 12 N Wentworth Ave., Londonderry, NH 03053

If your return is accepted, we’ll send you a return shipping label, as well as instructions on how and where to send your package. Items sent back to us without first requesting a return will not be accepted.

You can always contact us for any return question at sales@cannabislabware.com.


Damages and issues
Please inspect your order upon reception and contact us immediately if the item is defective, damaged or if you receive the wrong item, so that we can evaluate the issue and make it right.


Exceptions / non-returnable items
Certain types of items cannot be returned, like perishable goods (such as food, flowers, or plants), custom products (such as special orders or personalized items), and personal care goods (such as beauty products). We also do not accept returns for hazardous materials, flammable liquids, or gases. Please get in touch if you have questions or concerns about your specific item.

Unfortunately, we cannot accept returns on sale items or gift cards.


Exchanges
The fastest way to ensure you get what you want is to return the item you have, and once the return is accepted, make a separate purchase for the new item.


European Union 14 day cooling off period
Notwithstanding the above, if the merchandise is being shipped into the European Union, you have the right to cancel or return your order within 14 days, for any reason and without a justification. As above, your item must be in the same condition that you received it, unworn or unused, with tags, and in its original packaging. You’ll also need the receipt or proof of purchase.


Refunds
We will notify you once we’ve received and inspected your return, and let you know if the refund was approved or not. If approved, you’ll be automatically refunded on your original payment method within 10 business days. Please remember it can take some time for your bank or credit card company to process and post the refund too.
If more than 15 business days have passed since we’ve approved your return, please contact us at sales@cannabislabware.com.

Frequently Asked Questions

Using certified laboratory consumables with documented material specifications strengthens compliance documentation during inspections. Cannabis labs that use validated filtration systems, USP Class compliant components, and traceable batch information are better prepared for regulatory audits. Reliable lab equipment demonstrates commitment to safety, quality control, and standardized operating procedures.
Cannabis laboratories should use chemical resistant media bottles, HDPE carboys, and solvent waste containers designed for laboratory use. Proper labeling, compatible caps, and secure storage areas help meet OSHA safety standards and local cannabis regulations. Using compliant lab storage solutions reduces spill risk and improves audit readiness.
Sterile filtration removes microorganisms and fine particulates that may interfere with potency testing and analytical accuracy. In cannabis testing laboratories, sterile bottle top filters and certified membrane filters help maintain sample integrity, prevent contamination, and support reliable lab results required for regulatory approval and product safety verification.
For high volume cannabis processing labs, large capacity bottle top vacuum filters, membrane disc filters, and heavy-duty vacuum filtration systems are preferred. These solutions support faster throughput, reduced downtime, and consistent extract clarity. Choosing scalable filtration equipment helps commercial cannabis labs maintain productivity while meeting quality standards.
Selecting the right membrane material depends on solvent type and application. PES membranes are ideal for aqueous solutions due to high flow rates and low protein binding. Nylon membranes offer broad chemical compatibility, making them suitable for aggressive solvents used in cannabis extraction. Always verify solvent resistance and pore size to ensure safe and efficient filtration performance.
Yes, approved labs follow cleanroom protocols, sterile pipetting techniques, and validated filtration steps to reduce contamination and ensure integrity of cannabis potency and safety testing. Proper consumables and cleanliness reduce cross-contamination risk.
Labs should retain product certifications, batch traceability documents, calibration records, and SOPs for equipment and consumables. This documentation supports compliance with state regulations and quality testing requirements in cannabis labs.
Cannabis laboratories maintain compliance with OSHA safety CDC complaint protocols, solvent handling procedures, ventilation standards, and proper consumables that resist chemical degradation. Using certified labware reduces hazard risks related to explosive or volatile solvents.
USP Class VI and FDA-approved filters maintain high quality and regulatory compliance by meeting stringent material safety and chemical performance benchmarks, which is crucial for labs producing test results and products that must meet legal and health requirements.
Cannabis labs should follow industry standards for laboratory glassware and consumables such as USP Class VI and FDA-compliant materials. Verified specifications ensure chemical compatibility, sterility, and safety for handling solvent and extracts in testing and manufacturing environments
Essential accessories include pedestal bases, ring-stand cradles, vacuum hardware, and replacement filter units each enhancing setup stability and hands-free operation for high-volume filtration workflows.
Cannabis labs frequently use heavy-duty HDPE or PETG media bottles, Boston square bottles, and HDPE carboys with chemical-resistant caps. These storage solutions support solvent handling, waste collection, and safe transport of lab liquids.
When comparing filters, consider the intended use: larger pores (0.2 μm or 0.45 μm) may be better for bulk particulate removal. Evaluate flow rates, chemical compatibility, and membrane material for your specific extract.
Top vacuum filtration solutions include Autofil® 2 and EZLabpure bottle top vacuum filters in various volumes (50 ml – 1000 ml), EZFlow® membrane disc filters, and compatible filtration hardware. These products are optimized for solvent clarity, reliability, and ease of use in cannabis lab processes.
Using purpose-built consumables like sterile pipette tips, robust media bottles, and compatible carboys helps labs reduce contamination risk, improve repeatability, and support high throughput in cannabis testing and production operations.
High-flow PES filters provide rapid filtration with low protein binding and chemical compatibility, making them efficient for aqueous filtration and minimizing processing time in cannabis extraction and sample preparation workflows.
Membrane pore size (0.2 μm or 0.45 μm) determines the level of particulate removal and clarity. Smaller pore sizes capture finer particles for clearer extracts, making them suitable for quality-controlled cannabis testing and downstream processing.
Bottle top vacuum filters use a membrane filter to clarify solvents by drawing liquid through the membrane with vacuum pressure, separating particulates and improving extract purity. These are key filtration products used in cannabis labs for sterile clarification and solvent cleanup.
CannabisLabware.com offers a full range of filtration and lab safety laboratory supplies including bottle top vacuum filters, membrane disc filters, centrifuge filter units, media bottles, carboys, solvent waste systems, and other consumables tailored for cannabis and hemp testing and production labs.
