Good product. Great packaging. Quick delivery.

I compared multiple freeze dryers from different companies and finally chose this one from StonyLab. It works great, is easy to use, and feels well-built. I'm very satisfied with the performance - definitely a smart purchase!

Correction: FYI: This item (Asin P/N: B07XG77YVG) has a male M8-1 threaded shaft. Material look like it's Steel with Zinc plating.

Very good.

I have purchased several funnels from Stonylab over the years. I have always found them to be a good value for the money. Whoever said the price was high has obviously never bought equipment from any top brand. I found the price to quality ratio to be amazing and surprising. The quality is very good, the funnel works well and it's durable. It is well made. This is most likely the best value funnel available. Stonylab shipped it immediately after the order and it was in my hands soon after that. I am writing this review with full gratitude and appreciation for Stonylab. Thank you. I will be a return customer again.

Surface of the electrode is smooth, with no obvious bumps or cracks, which is crucial for experiments such as electrocatalysis and voltammetric analysis.

Connect condenser tube, thermometer and stirrer at the same time, the interface sealing is perfect, and the experimental efficiency is increased by more than 50%.

Compared with some imported brands of equipment, the price of this electrostatic spinning machine is more reasonable, but the function is completely enough, very suitable for laboratories with limited budget.

The glass is translucent, so you can clearly see the powder flow and easily control the pouring speed.

Standard interface, can be applied to 24/40 milled vessels in the laboratory, good compatibility.

Graphite electrodes are an ideal choice for fuel cell research.

We received the goods soon after the order was placed, the packaging was intact, and it was not damaged during transportation, which is very suitable for the situation where we need to replenish the experimental materials quickly.

When used in contact with slightly hot utensils, there was no blowing or breaking.

Product is firmly packed, no damage during transportation.
