Why do we choose clamp sample bottle and screw sample bottle?

As a common chromatographic laboratory consumables for GC and HPLC, the material, hardness, color, size, volume and shape of the sample bottle, the material of the cap and gasket, the size of the central opening, and even the recovery rate of the sample bottle should be considered when selecting the sample bottle Why do you choose the sample bottle with jaw cover? The jaw sample bottle cap can ensure the maximum tightness and reduce the probability of sample volatilization For example, the sample bottle with hammay jaw and the matching cap / spacer and ergonomic manual capper / cap lifter The new hammay ergonomic manual capper and opener adopt lightweight and streamlined design (the same design of Agilent capper) to reduce wrist pain and discomfort caused by force The weight is 25-30% lighter than the model designed earlier, and the problems of hand pain and hand clamping are eliminated at the same time The new design greatly improves the user experience This tool is a necessity for every laboratory The design concept of the new type of capping device is durability: at least 100000 caps are sealed by 11 mm capping device, and 80000 caps are sealed by 20 mm capping device before wearing affecting the usability
The new hammay ergonomic manual cover sealer and cover opener are light, comfortable and ergonomically designed The handle fits with both hands, so there is no danger of hand clamping The top mounted adjustment knob indicates the direction of tightening / loosening The adjustment knob can also be used as an indicator of the completion of cover sealing or cover opening The narrow jaw design makes the upper part of the sample bottle obtain greater vertical clearance The bottom The handle is easy to control and improves the stability of the jaw; the handle is made of durable fiber-reinforced resin and reinforced with steel structure in the middle Why to choose 8 mm thread mouth sample bottle? 8 mm thread mouth sample bottle is the smallest opening automatic sample feeder bottle, which is specially designed for various automatic sample feeders used in narrow neck bottles 8 mm screw cap and spacer have been assembled to reduce the chance of hand contamination during sample preparation For example, hammay 8 mm narrow thread port sample bottle, 9 mm wide thread port sample bottle and matching inner liner According to different materials, Hamai glass sample bottle can be divided into two types, one is domestic borosilicate, the other is imported first-class hydrolyzed glass to meet different levels of customer needs, with the specification of 11.6 * 32mm Sample bottle for standard GC and HPLC, small caliber, 8-425 standard thread port, can be used for sample storage of automatic sampler, and can be used with 8-425 thread port bottle cap spacer 8-425 autosampler is often used in combination with Shimadzu, spectrophysics, Varian, and other autosamplers The bottles are made of colorless class 1 A or amber class 1 B borosilicate glass with a writable label for sample identification The cap is made of high quality polypropylene, with precise manufacturing tolerance and controllable manufacturing environment The gasket is made of the highest quality PTFE / silica gel to ensure the high efficiency of the function.
