This policy explains how PX Scientific Goods dispatches orders, what carriers we use, what it costs, and what happens when a shipment is delayed, damaged or lost. It applies to every order placed on this site.
Processing time
Orders for in-stock items placed before 1:00 pm Central Time on a business day are picked the same day and dispatched the next business day. Orders placed after that cut-off, or at a weekend or public holiday, are processed on the following business day. Glassware and any item requiring additional protective packing may add one business day; where that applies we tell you by email rather than letting the order go quiet.
If an item turns out to be short on stock after you have ordered, we contact you within one business day with the real lead time and give you the choice of waiting, substituting, or cancelling that line for a full refund. We do not part-ship without telling you first.
Carriers, zones and transit times
We ship within the United States, including Alaska, Hawaii and Puerto Rico, using UPS and USPS. Ground services typically deliver in two to six business days depending on zone. Expedited two-day and next-day services are available at checkout where the destination supports them. Transit times are carrier estimates and begin the day after dispatch, not the day you order.
Heavier or bulkier items — benchtop instruments, cases of glassware, spill kits — may ship freight or in multiple parcels. Where an order splits, every parcel is tracked and you receive tracking for each.
Shipping charges
Shipping is calculated at checkout from the actual dimensional weight and destination of your order. We do not add a handling surcharge and we do not inflate shipping to subsidise product pricing. Orders over the threshold shown at checkout ship free on standard ground within the contiguous United States.
Tracking
A tracking number is emailed as soon as the label is generated. Please allow up to twenty-four hours for the carrier’s first scan; a number that shows no movement overnight is normal and does not mean the parcel is lost.
Damage, loss and shortages
Inspect your delivery on arrival. If glassware arrives broken, photograph the outer carton, the internal packing and the item, and contact us within five business days at support@pxscientificgoods.store. We will replace the item or refund it, and we file the carrier claim ourselves — that is our job, not yours.
If tracking shows delivered and the parcel is not there, tell us within seven days. We will open a carrier trace. Traces typically take three to eight business days; we will not leave you waiting without an update while one is open.
Shortages must be reported within five business days of delivery so we can reconcile the pick against the packing list.
Addresses and refused deliveries
We ship to the address you enter. Please check it before completing checkout — once a label is generated, a change is at the carrier’s discretion and may incur a fee. Parcels refused at delivery or returned as undeliverable are refunded less the actual outbound and return shipping cost.
International
We do not currently ship outside the United States. Where duties or import charges would apply to a future international service, they would be the responsibility of the recipient.
