200ml Glass Volumetric Flask

200ml Glass Volumetric Flask

Guide Medlab 200ml volumetric flasks are precision‑grade volumetric glassware crafted from 3.3 borosilicate glass. As practical medium‑capacity lab vessels, they work great for standard‑solution preparation and precise dilution in routine analytical tasks. Calibrated at 20 °C with distinct etched graduation marks, these flasks support either ground glass stoppers or plastic stoppers as your selection. Featuring solid chemical resistance, they suit daily lab work in chemical laboratories, pharmaceutical QC departments and educational teaching labs.

Usage

Before using a 200ml volumetric flask, complete two key checks.

First, confirm the flask capacity matches your experimental requirements.

Second, verify that the stopper fits snugly with no liquid leakage. Perform the leak test twice: the stopper may fail to seal properly at certain rotation positions along the flask neck.

Application

Guide Medlab 200ml glass volumetric flasks are precision‑class volumetric vessels crafted from 3.3 borosilicate glass. Built for high‑accuracy medium‑volume solution preparation and quantitative dilution, they come with etched graduation marks calibrated at 20 °C. They are widely applied in analytical chemistry labs, pharmaceutical quality control, environmental testing and university teaching facilities.
• Accurate preparation of medium‑volume standard solutions and reference reagents
• Precise quantitative dilution of test samples for instrumental analytical work
• Constant‑volume handling for chemical and physical performance tests
• Quantitative sample setup for lab calibration and routine QC procedures

FAQ

Q1: Do you offer free samples?

Yes, we provide free samples (usually 5‑10pcs) for your evaluation. Shipping cost is covered by the customer or negotiated separately.

Q2: What is the minimum order quantity (MOQ)?

MOQ varies for glass labware. For this 200ml glass volumetric flask, MOQ is 5 cartons. Reinforced export carton packaging is applied to lower breakage risk during transportation.

Q3: What payment methods do you accept?

We accept T/T (bank transfer) or pay through Alibaba.

Q4: Can I add my own design or logo to the product?

Yes, we provide OEM/ODM service. Custom logo and customized packaging are both supported.

Q5: Can you provide CE and ISO for your products?

Yes, our glass volumetric flasks come with complete technical documentations including CE and ISO certificates. Material and calibration test reports can be provided on request.

Q6: Do you support shipping insurance and freight options?

Yes, shipping insurance is available for glass consignments to cover potential breakage. Multiple freight options can be matched according to your destination and delivery schedule.

Q7: What is your lead time for mass production?

Normally 7‑15 working days after receiving your deposit. Exact lead time depends on order volume and customization requirements.

Q8: How do you handle broken goods upon arrival?

All glass products are well‑packed for export. Please capture photos of damaged items and outer carton within 48 hours after receipt. We will discuss compensation or replacement based on actual damage condition.

Q9: What stopper types are available for this 200ml volumetric flask?

We offer two stopper choices: ground glass stopper and plastic stopper. Pick the proper option according to your experimental reagents.

Q10: Can this volumetric flask be applied for direct heating?

No. Volumetric flasks belong to precision‑grade measuring glassware. Direct heating is prohibited, as it may trigger volume deviation and permanent glass damage.

Q11: What calibration standard do these flasks comply with?

This 200ml volumetric flask features permanently etched graduation marks calibrated at 20 °C, built for reliable preparation and dilution of standard solutions.

Q12: Are other volumetric flask capacities available for selection?

We provide a complete series covering various volumetric flask sizes. Contact our team to obtain the full size chart and up‑to‑date quotation.

Q13: Could you share tips for daily operation and storage?

Keep flasks in dry indoor conditions and protect them from heavy impacts. Always pair each flask with its original matched stopper. Discard any scratched or cracked flasks to secure measurement accuracy and lab‑operation safety.
